Clever Corvids: vs. two-year olds
by David Turell , Saturday, December 13, 2014, 18:53 (3633 days ago) @ David Turell
The kids win:-http://www.wsj.com/articles/who-wins-when-smart-crows-and-kids-match-wits-1418230699?KEYWORDS=Alison+Gopnik-Here was the question: Would the crows or the children be able to use this accidental event to design a new action? Could they imagine how to procure the treat on purpose, even though they had never done it before? If they just saw the block sitting on the table, would they pick it up and put it in the machine?-Despite their tool-using brilliance, the crows never got it—even after a hundred trials. They could learn to pick up the block and put it into the box through conditioning—that is, if they were rewarded for each step of the process—but not spontaneously. In contrast, most of the 2-year-olds learned from the accident. They could imagine how to get the marble, and could immediately pick up the block and put it in the box.-The crows have a deep understanding of how physical objects work, and they are very clever at using that knowledge to accomplish their goals. But the children seem to be better at noticing the novel, the accidental and the serendipitous and at using that experience to imagine new opportunities. It may be that same ability which lets us humans fashion ancient mountains and lakes into magical new worlds.
Clever Corvids: analytic thinking

Crows can do it:-http://www.scientificamerican.com/article/crows-understand-analogies/?WT.mc_id=SA_DD_20150210-"Then, the critical test was given. Each card now pictured a pair of items. The middle card would display pairs AA or CD, and the two side cards would display pair BB and pair EF. The relation between one pair of items must be appreciated and then applied to a new pair of items to generate the correct answer: the BB card in the case of AA or the EF card in the case of CD. For instance, if the middle card displayed a circle and a cross, then the correct choice would be the side card containing a square and a triangle rather than the side card containing two squares.-"Not only could the crows correctly perform this task, but they did so spontaneously, from the very first presentations, without ever being trained to do so.-"It seems that initial training to match identical items enabled the crows to grasp a broadly applicable concept of sameness that could apply to the novel two-item analogy task. Such robust and uninstructed behavior represents the most convincing evidence yet of analogical reasoning in a non-primate animal, as only apes had spontaneously shown analogical reasoning after learning to match identical items."
Clever Corvids: clever Mexican jays
by David Turell , Saturday, May 23, 2015, 17:43 (3472 days ago) @ David Turell
Weighing peanut pods to get the right meal:-http://www.sciencedaily.com/releases/2015/05/150522174719.htm-"When we presented the jays with ten empty and ten full identically looking pods (pods without or with three nuts inside), we noticed that after picking them up the birds rejected the empty ones and accepted the full peanuts, without opening them." says Dr. Sang-im Lee of Seoul National University -- the corresponding author of the paper. A series of similar experiments with identically looking normal nuts and nuts that were 1g heavier (pods with some clay added) confirmed that jays always were able to distinguish and preferred the heavier nuts. How did they know which were empty without opening them? The researchers used slow motion videos to see what happens when the bird is deciding whether to drop or take away the peanut pod. "We found out that birds shake the nuts in their beaks. We think that these movements may provide them with the information generally similar to our feeling of "heaviness" when we handle an object in our hands," says Dr. Jablonski.-"In another experiment the researchers prepared one type of peanut pods by opening the shell, removing two out of the three nuts and closing the shell again. The second type of pod was prepared by opening a small pod, which normally contains only one nut, and closing it. Thus, the jays were to choose between nuts of similar content and mass but of different size. "The jays figured out that the larger pods did not weigh as much as they should and the birds preferred the smaller pods, which weighed as expected for their size," comments Dr. Fuszara. They behaved as if they knew that "something is wrong" with the larger nuts.-"So how do they know it? When they shake the nuts in their beaks, the birds produce sounds by opening and closing their beaks around the peanut shell for brief moments. The researchers think that the jays also take this sound into account. "Our next goal is to disentangle the role of sound relative to the perception of "heaviness," and to determine if jays use the same sensory cues for acorns -- their natural food," conclude Dr. Lee and Dr Jablonski."
Clever Corvids: keeping count
by David Turell , Tuesday, June 09, 2015, 18:02 (3455 days ago) @ David Turell
Crows definitely keep count:-http://www.sciencedaily.com/releases/2015/06/150608152002.htm-"Helen Ditz and Professor Andreas Nieder of the University of Tübingen found the neuronal basis of this numerical ability in crows. They trained crows to discriminate groups of dots. During performance, the team recorded the responses of individual neurons in an integrative area of the crow endbrain. This area also receives inputs from the visual system. The neurons ignore the dots' size, shape and arrangement and only extract their number. Each cell's response peaks at its respective preferred number.-"The study published in PNAS provides valuable insights into the biological roots of counting capabilities. "When a crow looks at three dots, grains or hunters, single neurons recognize the groups' 'threeness' ," says Helen Ditz. "This discovery shows that the ability to deal with abstract numerical concepts can be traced back to individual nerve cells in corvids." -"What makes this finding even more interesting is that a long evolutionary history separates us from birds. As a consequence, the brains of crows and humans are designed very differently."
Clever Corvids: using tools
by David Turell , Saturday, August 29, 2015, 00:08 (3375 days ago) @ David Turell
It seems they learn by some degree of emulation and trial and error:-http://www.sciencedaily.com/releases/2015/08/150826113817.htm-"She designed the experiment based on apparatus used by University of Leeds zoologist Will Hoppitt in a similar study he conducted on meerkats. "I used two apparatuses with multiple access points on each," she said, "so we could look at whether the crows were imitating or emulating, whether they were just paying attention to another crow's general location or whether they were paying attention to a specific area on an apparatus that another crow was interacting with."-"Logan and colleagues found that the crows don't imitate or copy actions at all. "So there goes that theory," she said. "Assuming how they learn in a non-tool context carries over to a tool context, they wouldn't copy the actions of individuals they see cutting up Pandanus leaves to make tools."-"But Logan and her team did strong evidence of social learning: If one crow sees a companion interacting with a particular area of the apparatus, reaching its bill through a door and pulling out a piece of boiled egg -- the treat -- the former is far more likely to try that particular door on either apparatus before choosing the other access options.-"'It's called stimulus enhancement," she explained. "That's the social learning mechanism they're using. But there's another interesting aspect: Once they see another bird interact with the door, they go to that door and then begin to solve the problem on their own. And now they completely ignore social information and they just use trial and error learning to open the door and extract the food.'"-Comment: Tool use has to be learned. It is not programmed as an instinct.

DAVID: Pray tell, how?-dhw: And if consciousness is an entity all by itself, and if animals, birds and insects have consciousness (though not on the same level as our own), why should it not be the same for bacteria?-DAVID: Because I think any degree of consciousness requires a brain. Because our consciousness is different than the organisms to which you refer. We have a consciousness which can foresee and plan for the future. Most animal research shows they live in the moment, with very little aspect of future planning found. As for your favorite bacteria, they respond immediately, only in the moment. This is the point you miss.-I can assure you I am perfectly aware of the colossal differences between our intelligence/consciousness and that of baboons, butterflies and bacteria. That is what I mean by “not on the same level as our own”. But in my view the ability to process information, take decisions and solve the vast range of problems posed by an ever changing environment still requires intelligence/consciousness. You acknowledge gradations of consciousness when we discuss animals and birds, and have even somewhat grudgingly acknowledged that my pet ants may have some degree of it, but...see below. -dhw: I am not myself arguing for or against dualism. The “emergence” of thought from chemical interactions is another explanation - with the product being greater than the sum of its parts. But if this is so for humans, it can also be so for bacteria, even without a brain. DAVID: I'm of the firm opinion that thought requires neurons.-And quite clearly there are many experts in the field who disagree with you, which is why I always find the firmness of your opinion so puzzling!

This study of a simple marine animal without neurons is an example of how simple chemical responses can control an animal's feeding technique:-http://phys.org/news/2015-09-animal-synapses-external-digestion-global.html-"They observed that when Trichoplax glides over a patch of algae, its cilia stop beating and it ceases moving, which indicates its ability to control its the entire body. The authors then found that cells of a certain cell type, called lipophils, simultaneously secretes granules whose contents rapidly break down the algae. This secretion appears to be targeted, indicating that the organism has local control, as only lipophils near algae released the granules. Trichoplax also appeared to pause while the algal content was ingested, and then resumed gliding. "- Comment: All of this can be mediate d by chemically sensing the presence of algae, and chemically signaling the feeding process.

Another example of automatic action by human single cells. In infection or inflammation from injury cells called neutrophils arrive and guide the action to kill the infective agent or repair the wound:-http://www.the-scientist.com/?articles.view/articleNo/43917/title/Neutrophils-Lead--T-Cells-Follow/-"Part of the innate immune system, white blood cells called neutrophils circulate in the blood and are the first responders to an influenza respiratory infection, guiding T cells—part of the adaptive immune response—to the site. Neutrophils create a physical trail of chemokines that allow T cells to home in on the infection site, according to a study published today (September 3) in Science.-"Using two-photon microscopy, Minsoo Kim, an immunologist at the University of Rochester Medical Center in New York and his colleagues visualized the mobilization of immune cells in response to an influenza virus-infection in the mouse trachea. The study is the first to track an immune system response to a flu virus in vivo.-“'The paper goes very far, using an infection model to not only describe a phenomenon, but to clarify the molecular cascade of events in impressive detail,”-***-"While the types of immune cells and their individual functions are increasingly well defined, how these cells interact and work together to fight pathogens has been difficult to study in live animals. It is well established that immune cells communicate with one another and with other tissues through messenger molecules called chemokines and cytokines. Cytokine messenger molecules made by innate immune cells in the blood are thought to help trigger T cells to differentiate into pathogen-specific killer cells. Chemokines guide immune cells to a site of infection. Both infected tissues and immune cells secrete chemokines, yet how cells follow the trails of these immune cell-secreted peptides has not been clear.-***-"For Kim, the phenomenon he and his colleagues have uncovered highlights the extent of collective behavior and shared information from animal species to the level of the cell. “This is individual cells sharing their experience and information to perform a team function,” he said."

You acknowledge this cooperative behaviour in animals as being intelligent, but you refuse to accept it in cells. Now these experts are telling you it's the same. The intelligence may be built in (and may have been put there by your God), but the information is passed around, processed and acted upon through cells communicating and cooperating, just like animals.

If I had to present your concept of what I presented in the above article I would have been laughed out of the class.-Once again: a person develops a small cut which bleeds and has some foreign material in it. Wounded skin sends out chemical signals for help. Blood vessels dilate and deliver extra edema fluid. Various white cells arrive and congregate at the scene. White cells equals pus. There are several types of white cells which are called for by need for the different types of infectious process. Platelets are called to stop the bleeding and initiate the clotting process which is a cascade of around 20 chemical reactions with feed back controls for the correct amounts of each step. And fibroblasts arrive to start the scarring process. All of this is automatic, controlled, stepwise, and none of the cells are thinking. Chemicals and hormones are acting spontaneously from the trauma. The cells and platelets I am describing above are all independently floating around in the blood stream and react to the chemical signals. I view this as equivalent to bacteria, and you must realize by now, I will not change my concept of how all this works. We come from bacteria by evolution, and cell processes were set way back then, and simply modified for multicellularity by specialization. That is evolutionary continuity.

When asked why the concept of bacterial cognition is controversial, he replied: “Large organs chauvinism, so we like to think that only we can do things in a cognitive way.” If what Kim and his colleagues uncovered is the conventional concept of automatic behaviour, why are they making a fuss about their discovery? Please explain what you think they mean by this phenomenon highlighting “the extent of collective behavior and shared information from animal species to the level of the cell.” Individuals sharing experiences and information, and working as a team, is a phenomenon integral to the functioning of all communities. You grant that these are signs of intelligence in humans and our fellow animals. What, then, do you think Kim and his colleagues are trying to draw our attention to by equating cell behaviour with that of the animal kingdom?-DAVID: I will not change my concept of how all this works. -Fair enough. You defend your beliefs and attack my hypothesis, and I defend my hypothesis and question your beliefs. That way, we may get some clarification.-DAVID: We come from bacteria by evolution, and cell processes were set way back then, and simply modified for multicellularity by specialization. That is evolutionary continuity.-I don't know what you mean by “simply modified for multicellularity by specialization”. In my hypothesis, evolution began with multicellularity, and each innovation was the result of cellular communities exploiting new conditions by pooling experience and information and working as a team, as per Kim and colleagues. (This fits in with the concept of the intelligent cell.) “Evolutionary continuity” is common descent, i.e. all organisms are descended from earlier organisms (regardless of innovative jumps), and specialization is the result of individual cells taking on a particular role within each cell community. Your concept of how it all works has been through divine preprogramming and/or divine dabbling, but you have taken to fudging it with terms like “guided”, “directed” and “semi-autonomous”, and “guidelines” (which turned out to be nothing more than the restrictions imposed by the nature of the organism and the environment). Now we have “innovative freedom so long as they fit God's desires”. I wonder how your Med School class would have responded to that. Be bold, be brave, be decisive, in the true tradition of all Texas cowboys, and shoot from the hip. Either God preprogrammed/dabbled evolutionary innovations (plus complex nests and lifestyles) or he didn't. Which is it?

That is not an over-interpretation. They are the words used by the researchers. Animals, including humans, share experiences and information in order to make decisions and solve problems. So do cells, according to these researchers. -DAVID: My view is the sharing of information is through chemical signals to which the cells respond automatically using the intelligent information and instructions they have to use.-Does this mean that God issued every different type of cell with detailed instructions on how to deal with every different type of problem? Unless he intervenes when each problem occurs, this means he must have preprogrammed the first cells with all the information and instructions to be passed down through billions of years....In the name of Ockham, wouldn't it be simpler if cells used their own (God-given?) intelligence to process and exchange new information as and when it came in, and to cooperate in taking their own decisions accordingly? dhw: If that denotes intelligence in us, it denotes intelligence in cells...... The hypothesis we are dealing with here relates only to the intelligence of living organisms and its possible (or even probable) influence on the course of evolution, which you have now agreed to, as above.-DAVID: Once again, the intelligent actions of cells are not equivalent to human intelligence and decision making.-No one is claiming that cells have the range or even the form of intelligence that we have. The claim is that within their own limitations, they work together intelligently and not automatically to reach their decisions.

The Pentadactyl pattern of feet as an example on board in the limitations instructions.-I see such patterns as examples of convergence, once certain intelligent cell communities had found the most efficient form of limb for their particular way of life. Of course there are vast numbers of cell communities that have devised different forms. That is the beauty of the independent inventive mechanism: it explains all the different varieties. -DAVID: My view is the sharing of information is through chemical signals to which the cells respond automatically using the intelligent information and instructions they have to use.

But the researchers are trying to find out what is behind their behaviour. You only focus on the physical manifestations, whereas they are trying to find the “thinking” that leads to those manifestations. You insist that the thinking doesn't exist, and they are only obeying instructions passed onto them since life began. See below:-dhw: In the name of Ockham, wouldn't it be simpler if cells used their own (God-given?) intelligence to process and exchange new information as and when it came in, and to cooperate in taking their own decisions accordingly? DAVID: Within limits and patterns as described above.-The limits are clear (individual and environmental). Bacteria will behave as bacteria, if that is what you mean by patterns. Perhaps their bacterial behaviour is caused by the fact that they “think” as bacteria.-dhw: No one is claiming that cells have the range or even the form of intelligence that we have.

Thanks to your intelligence, you were able to absorb and process all the information necessary for your role and then use it appropriately. You are not an automaton. Thanks to their intelligence, bacteria are able to absorb and process all the information necessary for their role and then use it appropriately. They are not automatons.

Luckily, the bugs have a symbiotic relationship with two species of bacteria -- one living inside the other in a situation unique to known biology -- to manufacture the nutrients sap doesn't provide. "The net result: The bacteria get a comfy mealybug home, and the bugs get the nutrition they need to live.”-Once more, huge thanks for sharing these wonders with us. -If these organisms have not worked out their own symbiotic relationship, who or what did? Are you telling me that God preprogrammed the first living cells to ensure that the mealybugs and bacteria would eventually get together? Or he dabbled to make them do it? You are faced with the same dilemma as with the weaverbird and its nest, the wasp that lays its eggs on a spider's back, the monarch butterfly that reproduces four times before emigrating, etc. You have finally conceded that these organisms may have an independent inventive intelligence of their own, but bacteria, which perform similar miracles of intricate design, have to have direct instructions from your God, because you cannot conceive of any intelligence without a brain. I still wonder why God has bothered to preprogramme such minutiae when apparently all he really wanted from evolution was us humans. But perhaps we humans can't exist without the mealybug/bacteria symbiosis.

The essence of my hypothesis is that it is individual living things (not life as an 'emergent entity') that have intelligent, inventive minds (of whatever sort). Information is not intelligent; minds are intelligent, and minds use information for planning. My final question once more concerned bacteria, as they may hold the key to the beginnings of evolution, but if you believe God preprogrammed, dabbles with or personally guides them in their countless ways of solving problems, so be it. God's planning on humans arriving seems to me to be feasible if I take the theist line; for me the problem lies in the idea that this was his purpose from the very start, and he geared the vast higgledy-piggledy history of evolution to this one outcome.

The finding that New Caledonian have a unique beak raises the old chicken/egg problem, beak first or tools first or saltation, both together:-http://phys.org/news/2016-03-unique-beak-evolved-tool-caledonian.html-"We used shape analysis and CT [computer tomography] scanning to compare the shape and structure of the New Caledonian crow's bill with some of its crow relatives and a woodpecker species with a similar foraging niche," said lead author Hunt.-"'This study shows that the unique bill contributes to the birds' ability to use and probably make tools," he said. "We argue that the beak became specialized for tool manipulation once the birds began using tools, and that this enhanced tool manipulation ability may have allowed the crows to make more complex tools."-"Such tools may range from sticks to barbed leaves or hooked twigs used to fish the crow's favorite food from the trunk of a tree - the juicy grubs of the longhorn beetle. The birds annoy their prey by poking around the grub's large, sensitive mandibles. When the grub grabs the stick or other tool, the bird hauls it out.-"'Their bill is shorter than a regular crow's," McGowan said. "It's blunter, and it doesn't curve down like nearly all bird bills do. The lower mandible actually curves slightly up, which likely gives it the strength it needs to hold the tool. And because the bill doesn't curve downward it brings the tool into the narrow range of the bird's binocular vision so it can better see what it is doing."-"Birds with blunter, straighter bills were probably more adept at handling tools for foraging and over time those features evolved, McGowan said. Tool use has now become ingrained in the crow's biology. In the case of the New Caledonian crow's beak, you might say it's not so much "you are what you eat," but "you are how you eat."-"'They hold the stick tool so that it goes up along the side of their head along the length of the bill," McGowan explains. "Apparently there are birds that favor one side of the head over the other—left-sticked or right-sticked, you could call it—it's really cool."-"The question that cannot be answered is why the crows started using tools in the first place. It may have been a matter of chance because most birds do just fine foraging with their beaks and feet without resorting to tool-making, McGowan said."-Comment: McGowan's point is the NC crows have a non-required phenotypic change. Why did it happen, or was it given?

You have already devoted several threads to the evolution of language, for which there is no known gene. Here we are talking about the evolution of behaviour. All the above behavioural attributes existed in animals that came long before us, and one can link all of them to the drive for survival and/or improvement. If you believe in common descent, you can hardly argue that they are “parallel” developments: they have remained constant right back to whatever ancestry you can think of.

dhw: I find it hard to believe that a crow using a stick to obtain its nosh will be unseen by other crows. In any case, there are crows all round where I live, and I see lots of them at a time. Perhaps yours are simply different from ours. I believe some species live in communities of thousands!-DAVID: Hyperbole won't do! I've seen flocks of birds as they migrate. Our crows don't flock.-A quick google has come up with the following: “Crows have been congregating in large roosts in the fall and winter for as long as there have been crows. Crow roosts can range from small scattered roosts of under one hundred individuals to the spectacularly large roosts of hundreds of thousands, or even more than a million crows! A roost in Fort Cobb, Oklahoma was estimated to hold over two million crows (Gerald Iams, 1972, State of Oklahoma Upland Game Inventory W-82-R-10). Most roosts are much smaller, but roosts of tens of thousands are common.” -dhw: And yes, I believe we inherited aggression, greed, territorialism from our fellow animals, just as we inherited parental love, social structures, and the need to explore.

I would suggest that is how evolution works. In the case of homo sapiens, the developments are so sophisticated that some folk don't even recognize that sending tanks into a neighbouring country is a development from Max the monkey snatching a banana from sister Minnie.

God did not need to preprogramme every Caledonian crow to start using tools. DAVID: Only when observation shows crows watching other crows inventing is your point valid.-We're not talking here about the internal combustion engine or rockets to Mars! Here are the inventions: QUOTE: “Such tools may range from sticks to barbed leaves or hooked twigs used to fish the crow's favorite food from the trunk of a tree - the juicy grubs of the longhorn beetle. The birds annoy their prey by poking around the grub's large, sensitive mandibles. When the grub grabs the stick or other tool, the bird hauls it out.”-Once upon a time, Christine Crow had an idea. She used a stick to get herself some lovely grub. Chris Crow was flying past when he saw her do it. “Caw!” said Chris, “that's a mighty fine idea. An' I reckon I c'd do the same with this here barbed leaf.” And as the years went by, Cressida and Crispin added their own variations, and beaks became adapted to the new method of grub-grabbing. And along came a middle-aged man with a long beard, and he took one look and said, “Holy Texas, you cawvids have just prooved mah theery of evolootion.”- A note for the purists: I know the accent is a poor imitation, neither the crows nor Darwin came from Texas, and the crows are still crows so they don't prove the theory. But I would like to think this wonderful tale, which is offered free of charge to the world of all true believers and non-believers, teaches us that crows might be able to use sticks and leaves without needing to be preprogrammed 3.8 billion years ago.

It displays itself through an intangible, immutable source we call consciousness that although it may always be intelligent, it shows signs of learning. Does this intelligence radiate from one point or from many? Did this intelligence begin as one or as many?-First of all, thank you for bringing a different dimension to our discussions. There is some dense thought here, which I find very attractive. I am a little queasy about the word “wise”, because it suggests sound judgement, as if ATI were somehow geared solely to goodness and beneficence. I see life very much as a mixture of good and bad, nice and nasty, and feel more at ease with a neutral “intelligence”! As for your two final questions, they are the hub of most of our discussions.-BBELLA: Whether intelligence has always been, or was sparked in one moment in a speck of light and matter connection before time began, or created all that IS or is All that Is, regardless - there should be no doubt, that when we look at what has been created and creations capabilities, that intelligence is definitely on a learning curve. Experience is every-thing. Without the memory of these experiences nothing exists to learn more. Intelligence learns and experiences and every thing benefits from it because everything is connected by intelligence.-I think this is a great approach, as it leaves all questions of origin, purpose and method wide open. Where I struggle a little is with the impression that intelligence or the “intangible, immutable source we call consciousness” somehow has an existence of its own. This straight away conjures up the idea of the single mind people call God (see David's comment), but I don't think that is what you mean, although it is one possible option. Intelligence is everywhere, and it provides a link between All That Is, but there has to be room in this concept for individuality. Individual intelligences have individual characteristics, memories, experiences (I'm not just talking about humans), and in that sense although all things are part of the great oneness, all things are also separate from it. BBELLA: Whether there was/is ONE intelligent being conducting/experiencing this experiment or many - does it really matter when we are ALL together in the midst of this great creative learning curve of transmutation of mind, emotions and matter? Whether it's only ONE mind watching all that IS, or All minds watching - we are all a-changing into the unknown.-For religious people of course the alternatives matter enormously, and when I was very young they mattered enormously to me too. If there is a God, what is he like, and what does he want? Now, though, I am fascinated by the whole mystery without any of the “Angst” that pervades some religious approaches. Yours for me represents an enlightened form of agnosticism, in which one embraces the mystery and the wonderment of it all, and accepts the impossibility of knowing the answers - at least until “we have shuffled off this mortal coil”!-DAVID (in answer to BBella): I still think you and I are very close together in our thinking. You are 'almost' describing my universal consciousness. At issue is the concept that IT is all knowing or learning, the latter an idea that dhw has brought up also.-That is the danger of making intelligence or consciousness sound like a single mind. You, David, think BBella's concept is close to yours, whereas I see it as completely open - and therefore close to mine! The difference between an all-knowing and a learning “IT” still conjures up the image of intelligence as a single mind (I think process theology favours a learning God). The concept of intelligence being present in all things and linking all things allows for a single mind but, as I understand it, also allows for an infinite number of different minds without - and this is the crucial distinction - any central “authority”. But I hope BBella will clarify this for us.

Another example:-https://www.sciencedaily.com/releases/2016/04/160426101527.htm-"A study led by researchers at Lund University in Sweden suggests that ravens can be as clever as chimpanzees, despite having much smaller brains, indicating that rather than the size of the brain, the neuronal density and the structure of the birds' brains play an important role in terms of their intelligence.- "'Absolute brain size is not the whole story. We found that corvid birds performed as well as great apes, despite having much smaller brains," says Can Kabadayi, doctoral student in Cognitive Science.-"Intelligence is difficult to test, but one aspect of being clever is inhibitory control, and the ability to override animal impulses and choose a more rational behaviour. Researchers at Duke University, USA, conducted a large-scale study in 2014, where they compared the inhibitory control of 36 different animal species, mainly primates and apes. The team used the established cylinder test, where food is placed in a transparent tube with openings on both sides. The challenge for the animal is to retrieve the food using the side openings, instead of trying to reach for it directly. To succeed, the animal has to show constraint and choose a more efficient strategy for obtaining the food. The team first trained the birds to obtain a treat in an opaque tube with a hole at each end. Then they repeated the test with a transparent tube. The animal impulse would naturally be to go straight for the tube as they saw the food. However, all of the ravens chose to enter the tube from the ends in every try. The performance of the jackdaws and the crows came very close to 100%, comparable to a performance by bonobos and gorillas.-"'This shows that bird brains are quite efficient, despite having a smaller absolute brain size. As indicated by the study, there might be other factors apart from absolute brain size that are important for intelligence, such as neuronal density," says Can Kabadayi, and continues:-"'There is still so much we need to understand and learn about the relationship between intelligence and brain size, as well as the structure of a bird's brain, but this study clearly shows that bird brains are not simply birdbrains after all!'"-Comment: It is the quality of the brain not the size.
Clever Corvids: due to neuron number and design
by David Turell , Tuesday, June 14, 2016, 15:52 (3084 days ago) @ David Turell
The latest research shows that bird brains have more neurons in the frontal area than monkeys and a primate-like design pattern of the neuron networks:-https://www.sciencedaily.com/releases/2016/06/160613153411.htm-"The first study to systematically measure the number of neurons in the brains of birds has found that they have significantly more neurons packed into their small brains than are stuffed into mammalian and even primate brains of the same mass. -"The macaw has a brain the size of an unshelled walnut, while the macaque monkey has a brain about the size of a lemon. Nevertheless, the macaw has more neurons in its forebrain -- the portion of the brain associated with intelligent behavior -- than the macaque.-"That is one of the surprising results of the first study to systematically measure the number of neurons in the brains of more than two dozen species of birds ranging in size from the tiny zebra finch to the six-foot-tall emu, which found that they consistently have more neurons packed into their small brains than are stuffed into mammalian or even primate brains of the same mass.-***-"Scientists were left with a generally unsatisfactory fallback position: Avian brains must simply be wired in a completely different fashion from primate brains. Two years ago, even this hypothesis was knocked down by a detailed study of pigeon brains, which concluded that they are, in fact, organized along quite similar lines to those of primates.-***-"'We found that birds, especially songbirds and parrots, have surprisingly large numbers of neurons in their pallium: the part of the brain that corresponds to the cerebral cortex, which supports higher cognition functions such as planning for the future or finding patterns. That explains why they exhibit levels of cognition at least as complex as primates," said Herculano-Houzel, who recently joined the Vanderbilt psychology department.-"That is possible because the neurons in avian brains are much smaller and more densely packed than those in mammalian brains, the study found. Parrot and songbird brains, for example, contain about twice as many neurons as primate brains of the same mass and two to four times as many neurons as equivalent rodent brains.-"Not only are neurons packed into the brains of parrots and crows at a much higher density than in primate brains, but the proportion of neurons in the forebrain is also significantly higher, the study found.-"'In designing brains, nature has two parameters it can play with: the size and number of neurons and the distribution of neurons across different brain centers," said Herculano-Houzel, "and in birds we find that nature has used both of them."-***-"One of the important implications of the study, the neuroscientist said, is that it demonstrates that there is more than one way to build larger brains. Previously, neuroanatomists thought that as brains grew larger neurons had to grow bigger as well because they had to connect over longer distances. "But bird brains show that there are other ways to add neurons: keep most neurons small and locally connected and only allow a small percentage to grow large enough to make the longer connections. This keeps the average size of the neurons down," she explained."-Comment: Brain size as a measure of intellectual function is out the window. It is a matter of neuron-packing and a more advanced network design.
Clever Corvids: Hawaiin species found
by David Turell , Wednesday, September 14, 2016, 19:56 (2992 days ago) @ David Turell
New Caledonian crows are very special using tools. Now another crow species in Hawaii is found as talented. They are geographically very far apart, and had a common ancestor 11 million years ago. This is probably learned behavior as a convergence in a species with great talent to begin with:-https://www.sciencedaily.com/releases/2016/09/160914135925.htm-"An international team of scientists and conservation experts has discovered that the critically-endangered Hawaiian crow, or 'Alal?, is a highly proficient tool user, according to a paper published today in the scientific journal Nature.-***-"'We had previously noticed that New Caledonian crows have unusually straight bills, and wondered whether this may be an adaptation for holding tools, similar to humans' opposable thumb," Rutz elaborates. By searching for this tell-tale sign amongst some of the lesser-known corvid species, he quickly homed in on a particularly promising candidate for further investigation -- the 'Alal?.-***-"We tested 104 of the 109 'Alal? alive at the time, and found that the vast majority of them spontaneously used tools," says Masuda. Current evidence strongly suggests that tool use is part of the species' natural behavioural repertoire, rather than being a quirk that arose in captivity, according to Rutz: "Using tools comes naturally to 'Alal?. These birds had no specific training prior to our study, yet most of them were incredibly skilled at handling stick tools, and even swiftly extracted bait from demanding tasks. In many regards, the 'Alal? is very similar to the New Caledonian crow, which my team has been studying for over 10 years."-"Experts have applauded the 'tour de force' of controlled experiments. "Most studies in our field investigate just a handful of subjects, so it is truly mindboggling to see an entire species tested," comments Professor Thomas Bugnyar, a corvid expert at the University of Vienna, Austria, who was not involved in the study.-***-"The discovery of a second tool-using crow species finally provides leverage for addressing long-standing questions about the evolution of animal tool behaviour. "As crow species go, the 'Alal? and the New Caledonian crow are only very distantly related. With their last common ancestor living around 11 million years ago, it seems safe to assume that their tool-using skills arose independently," explains Rutz. "It is striking that both species evolved on remote tropical islands in the Pacific Ocean that lack woodpeckers and ferocious bird predators -- perfect conditions, apparently, for smart crows to become accomplished tool users!'"-Comment: Animals with bright brains can learn, develop simple tool techniques which then become instinct, as this study appears to show. No where near as complex as tying weaver nests, but an interesting comparison.
Clever Corvids: parrots using tools
by David Turell , Wednesday, December 16, 2015, 01:26 (3266 days ago) @ dhw
Grinding with a stone:-http://phys.org/news/2015-12-evidence-tool-parrots.html-"Studying ten captive parrots, researchers in the Department of Psychology at York observed the birds adopt a novel tool-using technique to acquire calcium from seashells and also the active sharing of tools among themselves.-"The birds used small pebbles or date pits to grind calcium powder from the shells or to break off small pieces of shell to ingest. This behaviour, never before seen in this species, is the first evidence of a nonhuman using tools for grinding, and one of the few reports of nonhuman animals sharing tools directly.-***-"Five out of ten birds were documented using tools, placing either pebbles or date pits inside shells to grind against the shell, or using them as a wedge to break apart the seashell.-"Interest in the shells was greatest from March to mid-April, just before the breeding season - this may be due to calcium supplementation being critical for egg-laying. Researchers were therefore initially surprised to find that it was the males, not the females who showed the greatest interest in shells.-"However, observation of the parrots' breeding behaviour showed that males often engaged in regurgitative feeding of females before copulating with them, thus potentially passing on the calcium benefits.-"Megan Lambert, PhD student in York's Department of Psychology and lead author on the study, said: "The use of tools by nonhuman animals remains an exceedingly rare phenomenon. These observations provide new insights into the tool-using capabilities of parrots and give rise to further questions as to why this species uses tools.-"'Tool use could reflect an innate predisposition in the parrots, or it could be the result of individual trial and error learning or some form of social learning. Whether these birds also use tools in the wild remains to be explored, but ultimately these observations highlight the greater vasa parrot as a species of interest for further studies of physical cognition.'"-Comment: 'Exceedingly rare' but fascinating. Found in captivity, it may also occur in nature.
Clever Corvids: hooked tools & saving them
by David Turell , Wednesday, December 23, 2015, 15:55 (3258 days ago) @ David Turell
Using tiny cameras crows are observed fashioning the hooks and there is evidence they save them:-http://phys.org/news/2015-12-crows-caught-camera-fashioning-special.html-"The pair developed tiny video 'spy-cameras' which were attached to the crows, to observe their natural foraging behaviour.-"They discovered two instances of hooked stick tool making on the footage they recorded, with one crow spending a minute making the tool, before using it to probe for food in tree crevices and even in leaf litter on the ground.-***-"'In one scene, a crow drops its tool, and then recovers it from the ground shortly afterwards, suggesting they value their tools and don't simply discard them after a single use." According to Rutz, this observation agrees with recent aviary experiments conducted by his group: "Crows really hate losing their tools, and will use all sorts of tricks to keep them safe. We even observed them storing tools temporarily in tree holes, the same way a human would put a treasured pen into a pen holder."-***-"They can use their bills to whittle twigs and leaves into bug-grabbing implements; some believe their tool-use is so advanced that it rivals that of some primates."
Clever Corvids: observe their dead
by David Turell , Saturday, January 09, 2016, 05:26 (3242 days ago) @ David Turell
Crows gather around and observe their dead:-http://www.livescience.com/53283-why-crows-hold-funerals.html?cmpid=NL_LS_weekly_2016-1-08-The researchers went to great lengths to design the "threats" they used to test the crows. They set up feeding areas for urban wild crows and sent trained volunteers to visit, carrying different objects that were carefully selected to test the crows' alarm responses: taxidermy crows arranged in poses suggesting that they were dead, and taxidermy red-tailed hawks, which prey on crows, posed on a branch as though they were still alive.-***-The scientists conducted similar tests with another urban bird, the rock pigeon, and observed that they hardly even noticed when a dead pigeon was paraded in front of them, a dramatic contrast to the organized and negative reaction of the crows to the sight of a fallen comrade. And the crows were similarly unconcerned about the presence of a dead pigeon, reserving their scolding and mobbing for humans accompanying dead crows and suspected predators.-The study results suggest that not only do crows notice and react to the sight of a dead crow, but they also quickly learn to associate danger and threat with humans who appear in close proximity to dead crows, recognizing them as a distinct and different caws for alarm.-Comment: Crows are clever. Nothing more.
Clever Corvids: a degree of abstract thought
by David Turell , Wednesday, February 03, 2016, 01:10 (3217 days ago) @ David Turell
An experiment in which Ravens are allowed to know another bird might be present to steal food from their cache, and how they react:-http://phys.org/news/2016-02-birds-theorize-minds.html-"The study, "Ravens Attribute Visual Access to Unseen Competitors," was published Feb. 2 in Nature Communications. It found that ravens guarded caches of food against discovery in response to the sounds of other ravens if a nearby peephole was open, even if they did not see another bird. They did not show the same concern when the peephole was closed, despite the auditory cues.-"The findings shed new light on science's understanding of Theory of Mind, the ability to attribute mental states - including vision - to others, said Cameron Buckner, assistant professor of philosophy at the University of Houston. Buckner is an author of the paper, along with Thomas Bugnyar and Stephan A. Reber, cognitive biologists at the University of Vienna.-***-"The ability to cache food is important to ravens, and previous research had shown they behave differently when they perceive a competitor watching. For example, when ravens are being watched, they hide food more quickly and are less likely to return to a previously made cache, both of which might reveal the location of a cache to a possible pilferer. If they do not think they are being watched, they spend more time on the task.-"This study involved two rooms, connected both by windows, which could be opened or covered, and by peepholes, which could be open or closed. The ravens were trained to look through the peepholes to observe a human experimenter making caches in the adjacent room. During the final phase of the test, both windows were covered but a peephole was open. A hidden speaker played sounds of a raven competitor, but no other bird was present. The subjects still cached as though they were being watched.-"'We show that ravens ... can generalize from their own experience using the peephole as a pilferer and predict that audible competitors could potentially see their caches (through the peephole)," the authors write. "Consequently, we argue that they represent 'seeing' in a way that cannot be reduced to the tracking of gaze cues."-"The findings offer needed information in several arenas, Buckner said, including evidence that ravens could serve as animal models in research involving social cognition.-"It also offers new evidence about the capacities involved in Theory of Mind and abstract thinking, Buckner said. "It could change our perception of human uniqueness, that we share some of that ability not just with chimpanzees and closely related species but also with a very different species."-"Buckner said the next step will be to see which other animals are capable of the kind of abstraction assessed in the peephole test, "especially humans, since we don't know when this ability emerges in childhood.-"'Finding that Theory of Mind is present in birds would require us to give up a popular story as to what makes humans special," he said. "But completing this evolutionary and developmental picture will bring us much closer to figuring out what's really unique about the human mind.'" -Comment: This study is straining at the bit. The birds hear other birds might be present. It doesn't take a very smart bird to recognize that a thief may be present nearby even if unseen and speedy caching is wise. Still those birds are bright.

Inference, possible.-I'm delighted to inform you that I have just finished reading a 10,000-page volume entitled Animal Cognition by Professor Ivor Fatt-Grant from the University of the State of the Bleedinobvious. I wish I could repeat for you some of the thousands of examples he cites, resulting from his 25 years of research studying every known organism on the planet, but I'll just try to sum up his conclusions. Every single organism appears to be aware of its environment and generally to know if the environment is safe or threatening. Of course threats may come in many forms, but I will focus here only on those from other organisms. Professor Fatt-Grant observed that whenever an organism perceived any sort of threat from another organism, it took precautions to protect itself. He inferred from the combination of threat and precaution that the threatened organism was able to gauge the intentions of the threatening organism, and he points out that reading another organism's intentions entails reading the other organism's mind. The reading of intentions as a form of mind-reading is clearly an integral feature of what we call “theory of mind”. However, Professor Fatt-Grant was unable to find a single volume on the subject compiled by any of the non-human organisms or communities he studied, and as they did not speak any language he could understand, he concluded tentatively that only humans have a fully fledged theory (a witty pun used in the chapter on birds). From our point of view, though, the all-important conclusion of his study is that all organisms are cognitive and all organisms are able to draw inferences from their cognitive powers that influence their behaviour. He even goes so far as to claim that if organisms did not have these cognitive powers and the ability to act upon inferences drawn from their readings of and communication with the mental processes of other organisms (there are also long sections on the subjects of cooperation and symbiosis), they would not survive.

Brain studies of the birds show they can mimic human brain function in different regions because the birds do not have neo-cortex: - http://nautil.us/issue/40/learning/why-neuroscientists-need-to-study-the-crow - "Corvids, such as crows, ravens, and magpies, are among the most intelligent birds on the planet—the list of their cognitive achievements goes on and on—yet neuroscientists have not scrutinized their brains for one simple reason: They don't have a neocortex. The obsession with the neocortex in neuroscience research is not unwarranted; what's unwarranted is the notion that the neocortex alone is responsible for sophisticated cognition. Because birds lack this structure—the most recently evolved portion of the mammalian brain, crucial to human intelligence—neuroscientists have largely and unfortunately neglected the neural basis of corvid intelligence. - "This makes them miss an opportunity for an important insight. Having diverged from mammals more than 300 million years ago, avian brains have had plenty of time to develop along remarkably different lines (instead of a cortex with its six layers of neatly arranged neurons, birds evolved groups of neurons densely packed into clusters called nuclei). So, any computational similarities between corvid and primate brains—which are so different neurally—would indicate the development of common solutions to shared evolutionary problems, like creating and storing memories, or learning from experience. If neuroscientists want to know how brains produce intelligence, looking solely at the neocortex won't cut it; they must study how corvid brains achieve the same clever behaviors that we see in ourselves and other mammals. - *** - "Examining the activity of over 300 neurons in two birds, Nieder's team found that the crow's NCL activity matched that of a primate's prefrontal cortex: Both of the species' neurons activated the most during the presentation of the rule cue, while activating much less in response to the images themselves. Some neurons responded specifically to the match cue (blue circle or glissando) and others to the non-match (red circle or noise); importantly, the neurons from each species activated in the same fashion regardless of the cue's sensory modality (auditory or visual). Nieder's results imply that both crows and primates evolved to use the same computation, albeit through radically different machinery, to solve the problem of representing abstract information—in this case, auditory or visual rules to a game. - *** - "Regardless of the dots' size and position, their quantity got encoded: Specific NCL neurons reacted to specific numbers, and activity in the NCL reflected the crows' behavior. The birds made more mistakes, for example, when comparing neighboring numbers, especially when the numbers were large (for instance, four versus five). This could potentially be explained by the pattern of neural activity Nieder saw in the NCL: Neurons that reacted strongly to higher numbers were also more likely to be activated by neighboring numbers than those that reacted to small numbers. Perhaps most intriguingly, the same behavioral and neural results were previously found in the primate PFC. That suggests that radically different brains may also have the same neural basis for the difficulty they each have in distinguishing large quantities. - "If, as Nieder told me, “the codes in the avian NCL and the mammalian PFC are the same, it suggests that there is one best neuronal solution to a common functional problem”—be it counting or abstract reasoning. What's fascinating is that these common computations come from such different machinery. One explanation for this evolutionary convergence could be that—beyond some basic requirements in processing—the manner in which neurons are connected does not make much difference: Perhaps different wiring in the NCL and PFC still somehow leads to the same neural dynamics." - Comment: This is an example of evolutionary convergence in brain function. Crows and humans are very far apart in mental ability, but these findings are a fascinatingview of how evolution progresses.
Clever Corvids: and others in a review
by David Turell , Sunday, December 04, 2016, 00:49 (2912 days ago) @ David Turell
Birds have mental skills that are amazing as research continues:
http://www.the-scientist.com/?articles.view/articleNo/47486/title/Birds-Have-Skills-Pre...
"For example, scientists have thoroughly documented the ability of Caledonian crows to use tools, a skill long believed to be employed only by humans. Similarly, researchers have shown that scrub jays remember past events and act accordingly. “And when it comes to numerical discriminations or word discriminations, pigeons have taken them all,” Scarf says.
"This year, Scarf, Colombo, and their colleagues tested pigeons’ ability to recognize patterns of letters that appear in the English language. Nearly every day for two years, Scarf trained four pigeons. He would place the birds in a box with a touch screen, and then present the animals with either a real or fake four-letter word, along with a star below the letters. If the word was real, the birds were to touch it with their beaks; if it was fake, they were to touch the star. If the subjects answered correctly, they would get a bit of wheat. At the end of the training, the pigeons were able to recognize dozens of words—including ones they had never seen before—with about 70 percent accuracy.
“'It’s quite a novel finding,” says Alex Kacelnik, who studies comparative cognition at the University of Oxford. “Showing that pigeons have, to a remarkable degree, the ability to process relations between letters in allowable or not allowable sequences is in my view extremely interesting.”
"Pigeons, of course, do not use written language, but Scarf suspects that they are accustomed to picking up patterns of visual objects. “The plasticity that seems to be inherent in not only the visual cortex of primates but also the visual cortex of pigeons makes them code letter pairs maybe like they would have coded object combinations or object features in the environment,” he says. Whether they are using the same part of the visual cortex that humans use to process words, however, remains to be seen, Scarf adds.
***
"Understanding how birds are capable of performing such advanced mental feats has proved tricky. For instance, in 1998, Nicky Clayton of the University of Cambridge and her colleagues found that scrub jays only searched for cached perishables soon after they had stored them, suggesting the birds think about the future and plan accordingly, but exactly how they do it remains a mystery.
***
"In some cases, it’s obvious that the birds are processing stimuli differently than humans are. Just this year, for example, Kacelnik and his University of Oxford colleague, zoologist Antone Martinho, showed that newborn ducklings imprinted the relative sizes and colors of two different objects: if they saw two equal-size objects when they were born, they will follow equal-size objects, even different ones, later in life. “This is a quite striking ability,” Kacelnik says. Such relational concepts are thought “to be only available to highly intelligent animals with a high level of training, and these animals do it in 15 minutes after they come out of the egg.'”
Comment: Finding this type of recognition ability in birds other than crows is not surprising. The question is how these birds developed the capacity, or was it given by God during evolutionary development.
Clever Corvids: and others. Chickens!
by David Turell , Wednesday, January 04, 2017, 01:03 (2881 days ago) @ David Turell
A review of research finds chickens can be seen as clever:
http://link.springer.com/article/10.1007%2Fs10071-016-1064-4
In this paper, I have identified a wide range of scientifically documented examples of complex cognitive, emotional, communicative, and social behavior in domestic chickens which should be the focus of further study. These capacities are, compellingly, similar to what we see in other animals regarded as highly intelligent. They include:
1.
Chickens possess a number of visual and spatial capacities, arguably dependent upon mental representation, such as some aspects of Stage four object permanence and illusory contours, on a par with other birds and mammals.
2.
Chickens possess some understanding of numerosity and share some very basic arithmetic capacities with other animals.
3.
Chickens can demonstrate self-control and self-assessment, and these capacities may indicate self-awareness.
4.
Chickens communicate in complex ways, including through referential communication, which may depend upon some level of self-awareness and the ability to take the perspective of another animal. This capacity, if present in chickens, would be shared with other highly intelligent and social species, including primates.
5.
Chickens have the capacity to reason and make logical inferences. For example, chickens are capable of simple forms of transitive inference, a capability that humans develop at approximately the age of seven.
6.
Chickens perceive time intervals and may be able to anticipate future events.
7.
Chickens are behaviorally sophisticated, discriminating among individuals, exhibiting Machiavellian-like social interactions, and learning socially in complex ways that are similar to humans.
8.
Chickens have complex negative and positive emotions, as well as a shared psychology with humans and other ethologically complex animals. They exhibit emotional contagion and some evidence for empathy.
9.
Chickens have distinct personalities, just like all animals who are cognitively, emotionally, and behaviorally complex individuals.
This is not to imply that the cognitive mechanisms underlying all of these apparent similarities are equivalent across species. Nor does it imply that higher-level explanations are always able to provide a thorough explanation of cognitive mechanisms. In fact, higher-level cognition is, unarguably, intertwined with more basic capacities and it may be contended that they are inseparable in many ways. Shettleworth (2010) argues that there is always an interplay between more fundamental cognitive mechanisms, e.g., associative learning, and other higher-level capacities, e.g., abstract thought, and that many human abilities derive from very basic cognitive processes. But the present findings do tell us that chickens, like other birds, are similar, in many ways, to mammals in their ethological complexity and that there are a number of findings that speak to the possibility of more complex capacities in chickens than heretofore recognized.

Clever Corvids: ravens can remember and plan
by David Turell , Thursday, July 13, 2017, 23:20 (2690 days ago) @ David Turell
Studies show they remember for many hours and plan:
https://www.newscientist.com/article/2140668-ravens-can-plan-for-future-as-well-as-4-ye...
"Ravens can plan for future events at least as well as 4-year-old humans and some adult, non-human great apes.
"The birds did this in tasks they wouldn’t encounter in the wild, so it isn’t an adaptation to an ecological niche, but rather a flexible cognitive ability that evolved independently in birds and hominids, whose lineages diverged about 320 million years ago.
"Planning for future events requires the use of long-term memory for some anticipated future gain. For a long time, it was thought to be a uniquely human trait. Children begin showing such abilities when they are about 4. But it turned out that chimpanzees, bonobos and orangutans have this ability too, making tools to use later on.
***
"Osvath and his colleagues wanted to see if ravens could plan for the future in tasks that aren’t their natural behaviours, such as tool use and bartering with humans.
"In one experiment, the ravens were first trained to use a stone to dislodge some dry dog food from a box. Later, the birds were shown a collection of objects, including the tool, without the box in sight. The researchers let the ravens select an object and 15 minutes later showed them the box at a different location with the reward in it. The birds had to drop the stone into the box to collect the food. The ravens succeeded, on average, in 11 of the 14 trials.
"The birds also took part in a bartering test. Again, they were first trained, in this case to exchange a token for a reward. Later, they had to select the correct token from a batch of objects, hold on to it for 15 minutes, and then exchange it with an experimenter to get a reward. The birds picked the correct token 143 out of 144 times, and were able to exchange about 77 per cent of the tokens for the reward.
"The researchers then increased the delay between the tool or token selection and its use to 17 hours. The ravens succeeded in the task nearly 90 per cent of the time.
"Crucially, the ravens were planning from the first trial onwards, suggesting that their success wasn’t due to habituation, says Osvath. “They can perform at the same levels as great apes, making a decision in the immediate situation for a future that will occur at another place,” he says.
“'This is new, very exciting evidence which we didn’t have before,” says Markus Boeckle at the University of Cambridge. “[It’s evidence] that general intelligence has also developed in birds. This is very important for understanding how intelligence evolves.'”
Comment: This study adds to the amazing intelligence these birds exhibit. It is not the size of the brain, but how it is connected inside.
Clever Corvids: handle probability better than we
by David Turell , Wednesday, May 30, 2018, 19:03 (2369 days ago) @ David Turell
Using the Monty Hall test of three opportunities, they succeed better than we:
https://www.livescience.com/6150-pigeons-beat-humans-solving-monty-hall-problem.html
"The so-called Monty Hall problem is a well-known puzzle named after the original host of the game show "Let's Make A Deal," who presented contestants with three doors, one of which held a prize, the other two only goats. The prize and the goats were placed randomly behind the doors beforehand, and stayed where they were throughout. After the contestant made a guess, Monty Hall would always open one of the remaining doors that he knew did not contain the prize. The player was then always given the option of staying with their initial guess or switching to the other unopened door.
***
"To see why the apparently illogical choice of switching is actually better, one must understand that before the host opened one of the three doors, the contestant did not know the location of the prize, and thus when he or she chose a door, the contestant had a 1-in-3 chance of being right. That does not change even after the host opened a door. If the probability of the first door the contestant chose remained the same, and there were only two doors left, that meant the remaining unopened door must have had a 2-in-3 chance of being right — that is, it had twice the chance of holding the prize.
***
"To shed light on why humans often fall short of the best strategy with this kind of problem, scientists investigated pigeons, which often perform quite impressively on tasks requiring them to estimate relative probabilities, in some cases eclipsing human performance. Other animals do not always share the same biases as people, and therefore might help provide explanations for our behavior.
"Scientists tested six pigeons with an apparatus with three keys. The keys lit up white to show a prize was available. After the birds pecked a key, one of the keys the bird did not choose deactivated, showing it was a wrong choice, and the other two lit up green. The pigeons were rewarded with bird feed if they made the right choice.
"In the experiments, the birds quickly reached the best strategy for the Monty Hall problem — going from switching roughly 36 percent of the time on day one to some 96 percent of the time on day 30.
"On the other hand, 12 undergraduate student volunteers failed to adopt the best strategy with a similar apparatus, even after 200 trials of practice each.
***
"The scientists propose the curious difference between pigeon and human behavior might be rooted in the difference between classical and empirical probability. In classical probability, one tries to figure out every possible outcome and make predictions without collecting data. In empirical probability, one makes predictions after tracking outcomes over time.
"Pigeons likely use empirical probability to solve the Monty Hall problem and appear to do so quite successfully.
"'Different species often find very different solutions to the same problems," Herbranson said. "We humans have ways of tackling probability-based problems that generally work pretty well for us, the Monty Hall dilemma being one notable exception. Pigeons apparently have a different approach, one that just happens to be better suited to the Monty Hall dilemma."
"Empirical probability is a slower, less elegant, brute-force method that can be tricked by the kind of random fluctuations seen in real data, Herbranson said, but it doesn't employ any mental rules of thumb that can lead to traps such as the Monty Hall problem. In a similar way, the visual systems we depend on to quickly make sense of the world around us can lead to our susceptibility to visual illusions, he added.
"Indeed, the aforementioned mathematician Paul Erdos demonstrated the power of empirical probability nicely as well. According to his biography, Erdos refused to accept the explanations of colleagues for the correct solution, and was eventually convinced only after he was shown a simple computer simulation than ran the problem hundreds of times. In other words, "after Erdos approached the problem like a pigeon, he was able to embrace the right answer," Herbranson said."
Comment: Sometimes our built-in biases get in the way.
Clever Corvids: making new tool from memory
by David Turell , Thursday, June 28, 2018, 19:31 (2340 days ago) @ David Turell
This is something humans can do, but crows do also:
https://www.newscientist.com/article/2172852-crows-make-the-right-tool-by-remembering-t...
"New Caledonian crows can remember what a tool looks like and then make a new one just from memory. The skill to make a mental image of something and then recreate it in this way is something usually only seen in humans.
"These crows are known to make a wide range of tools, including hooked and barbed sticks. But, until now, it wasn’t clear how certain tool designs were passed through generations, as the crows did not seem to just imitate other crows. Sarah Jelbert of the University of Cambridge, UK, and her team wanted to see if the crows were able to remember effective tool designs and recreate them.
"The team trained eight wild crows by initially offering them a choice between two small and two larger pre-fabricated cardboard vouchers. The cardboard vouchers released a reward – some meat – when they slid it with their beaks into the slot of a dispenser. Half the birds were taught that the larger vouchers earned the rewards, and half learned that the smaller vouchers worked.
"When Jelbert offered the birds an oversized card that wouldn’t fit through the slot, the birds gripped it with their claws and ripped it into shape with their beaks to the size that had most recently worked for them—either the smaller vouchers or the slightly larger ones. “The only way they could do this was by memorising what the ideal shape should be,” says Jelbert.
"Rather than copying how other crows make tools, they learned by focusing on the tool itself. They recognised its usefulness, remembered what it looked like and worked out how to make it anew. This might explain how the tools become increasingly complex over time as crows hold a mental image of the right tool and then make slight changes, which are then picked up by future generations.
“'They are performing a new behaviour,” she says. “They’ve transferred experience of what works for them into a combination of memory and manufacturing ability.'”
Comment: Yes, very clever.
Clever Corvids: making new tool from memory

Another take on it:
https://www.the-scientist.com/news-opinion/new-caledonian-crows-build-tools-from-mental...
"Crows from an island in the South Pacific are better than other avian species when it comes to crafting tools. Now, researchers propose that, unlike humans, New Caledonian crows don’t copy older members of the species to learn their trade but pick up tool making by taking a mental snapshot of the final product and manufacturing it in their own way.
"The researchers made a vending machine for the crows that doled out meaty rewards in exchange for particular sizes of card paper. The birds were trained to realize which sizes would result in a win. Next, the crows were given large sheets of paper that had to be ripped into smaller pieces in order to fit into the vending machine. The birds were given no hints about size this time around. However, the crows remembered the sizes of paper that had been productive previously and tore up the paper to match the winning sizes. This mental image that the New Caledonian crows seem to retain is called mental template matching.
“'If the crows remembered that a specific tool design worked and recreated it from memory, that could show how a culture of tool use might be spread throughout a population of birds,” Sarah Jelbert, who studies the cognitive behavior of animals at the University of Cambridge in the U.K. and a coauthor on the paper, tells BBC.
"According to The New York Times, the researchers need to provide more proof that the birds indeed carry out mental template matching. “This would seem to be experiment one in a series of other experiments,” Irene Pepperberg, who studies avian cognition at Harvard University and was not involved in this work, tells The Times.
"According to Gizmodo, Edward Wasserman, an experimental psychologist at the University of Iowa who was not involved in the study, says the findings were “clear and compelling,” while reiterating earlier avian research that implies birds are good at picking up tasks and memorizing them. Given that mammals and birds diverged millions of years ago, this would mean our last common ancestor was also intelligent or intelligence evolved in more than one way.
"According to the BBC, Jelbert agrees—intelligence may have taken different evolutionary routes."
Comment: It still takes brains to do the intellectual work.
Clever Corvids: inventing a tool to reach food
by David Turell , Wednesday, October 24, 2018, 20:25 (2222 days ago) @ David Turell
The research has crows putting pieces together to reach food:
https://www.sciencedaily.com/releases/2018/10/181024112201.htm
"The new study shows that these birds can create long-reaching tools out of short combinable parts -- an astonishing mental feat. Assemblage of different components into novel functional and manoeuvrable tools has, until now, only been observed in apes, and anthropologists regard early human compound tool manufacture as a significant step in brain evolution. Children take several years before creating novel tools, probably because it requires anticipating properties of yet unseen objects. Such anticipation, or planning, is usually interpreted as involving creative mental modelling and executive functions.
"The study demonstrates that this species of crow possess highly flexible abilities that allow them to solve complex problems involving anticipation of the properties of objects they have never seen. 'The finding is remarkable because the crows received no assistance or training in making these combinations, they figured it out by themselves,' says Auguste von Bayern, first author of the study from the Max-Planck-Institute for Ornithology and University of Oxford.
"The researchers presented eight New Caledonian crows with a puzzle box they had never encountered before, containing a small food container behind a door that left a narrow gap along the bottom. Initially, the scientists left some sufficiently long sticks scattered around, and all the birds rapidly picked one of them, inserted it through the front gap, and pushed the food to an opening on the side of the box. All eight birds did this without any difficulty. In the next steps, the scientists left the food deep inside the box but provided only short pieces, too short to reach the food. These short pieces could potentially be combined with each other, as some were hollow and others could fit inside them.
"Without any help or demonstration, four of the crows partially inserted one piece into another and used the resulting longer compound pole to reach and extract the food. At the end of the five-step investigation, the scientists made the task more difficult by supplying even shorter combinable parts, and found that one particular bird, 'Mango', was able to make compound tools out of three and even four parts.
"Although the authors explain that the mental processes by which the birds achieve their goals have not yet been fully established, the ability to invent a tool is interesting in itself. Few animals are capable of making and using tools, and also in human development the capacity only emerges late. While children start using tools reliably when they are about 18 months old, they only invent novel tools suited to solve a given problem reliably when they are at least five years old. Archaeological findings indicate that such compound tools arose only late in human cultural evolution (probably around 300,000 years ago in the Middle Palaeolithic) and might have coevolved with planning abilities, complex cognition and language. The crows' ability to construct novel compound tools does not imply that their cognitive mechanisms equal those of humans or apes, but helps to understand the cognitive processes that are necessary for physical problem solving."
Comment: This type of complex planning requires the ability to understand the future use of the parts, conscious reasoning. Caledonian crows are amazing, but they don't possess consciousness of our type. Obviously it is not the size of the brain that counts, but the quality of the neuronal activity, as shown by human neurons.

Cockatoos can make and use tools to reach food:
https://www.sciencedaily.com/releases/2018/11/181107172905.htm
"The Goffin's cockatoo (Cacatua goffiniana) is a type of parrot. Captive Goffins are capable of inventing and manipulating tools, even though they aren't known to use tools habitually. The authors of the present study investigated two questions: do Goffins adjust tool properties to save effort, and if so, how accurately can they adjust tool dimensions for the task? The authors supplied six adult cockatoos with large cardboard sheets to tear into strips as tools for the testing apparatus: a food platform with a food reward set at varying distances (4-16cm) behind a small opening which also varied in width (1-2cm).
"They found that the Goffins were capable of adjusting the length of their cardboard strip tools to account for variations in food distance, making shorter tools when the reward was closer than when it was set farther away. In every case, if a first-attempt tool was too short, the second-attempt tool would be significantly longer. On average, all six birds made significantly longer tools than were required to reach the reward in all test conditions, with the birds tending to make increasingly long tools as the study progressed -- perhaps as a risk-avoidance strategy.
"However, only one bird was able to make a sufficiently-narrow tool to successfully reach the food reward when the opening was at its narrowest. The authors hypothesize that the shearing technique the birds use to tear the cardboard limits the narrowness of the resulting strips.
"Alice Auersperg adds: "The way they inserted and discarded manufactured pieces of specific lengths differently depending on condition suggests that the cockatoos could indeed adjust their tool making behavior in the predicted direction but with some limits in accuracy.' "

Using more than one item to make a tool:
https://mindmatters.ai/2018/11/crows-can-be-as-smart-as-apes/
"Some (though not most) birds can learn new skills as readily as primates. New Zealand crows can create compound tools “by combining two or more otherwise non-functional elements, an ability so far observed only in humans and great apes”; they can though estimate sizes and shapes of paper for a reward, though they do not use paper in the wild.
"Some New Caledonian crows can use three tools in a row to reach food. As a result, some researchers have called crows “feathered primates.” New Zealand crows’ causal understanding (within limits) is said to rival that of 5-7 year old children. Or 7- to 10-year old children.
It’s not just crows, either. Pigeons can work with numbers up to nine with a success that is “indistinguishable from that displayed by monkeys.” Even the chicken’s intelligence “startles” some researchers (“communication skills on par with those of some primates”).
"Do such skills “redefine intelligence,” or explain “how technology evolved,” as sometimes claimed? Well, not really. It’s the same sort of intelligence as we find in primates but exhibited in a quite different brain structure:
"Corvids, such as crows, ravens and magpies, are among the most intelligent birds on the planet—the list of their cognitive achievements goes on and on—yet neuroscientists have not scrutinized their brains for one simple reason: They don’t have a neocortex. The obsession with the neocortex in neuroscience research is not unwarranted; what’s unwarranted is the notion that the neocortex alone is responsible for sophisticated cognition. Because birds lack this structure—the most recently evolved portion of the mammalian brain, crucial to human intelligence—neuroscientists have largely and unfortunately neglected the neural basis of corvid intelligence…
"If neuroscientists want to know how brains produce intelligence, looking solely at the neocortex won’t cut it; they must study how corvid brains achieve the same clever behaviors that we see in ourselves and other mammals.
"So brain structure cannot be the simple explanation we might have supposed. Can we turn to evolution for an explanation? Not really. We don’t know when, how, or why some birds started making and using stick tools so it’s hard to do more than speculate about the evolution of the trait.
"There’s another problem as well: The birds display these skills in a setting that humans have designed so that the birds might succeed (so that, in turn, the humans can publish in a science journal, of course). It’s fair to ask what role such focused, goal-oriented human intervention plays in increasing certain types of intelligence in the birds. The clear, systematic reward system not only exists but is designed to be apparent to the bird. Nature does not usually arrange such systems. If a bird seldom gets exactly the same test repeated in a natural state, its ability to learn may be frustrated, irrespective of its native intelligence.
"Some might respond by saying that only some species of birds are as clever as primates are with tools. That’s true, but then only some species of mammals are as clever as primates are about anything.
"We don’t know very much about intelligence in animals and birds but we do know that it is not a function of the mechanical organization of their brains. That raises a question: If artificial intelligence really came to exist, would it depend on the organization of the mechanism?"
Comment: Much more to the point is a mind that a works on problems are not a brain. IT always must be something more, as we know full well in humans.

You have misinterpreted my comment. We are back to the debate whether an action is understood as knowledgeably intended or automatic and the result of instinct. Those of us with consciousness know why we respond as we do. I've lived with dogs most of my life. When they lie down, on something soft or firm they inevitably curl their bodies and circle before they lie. The standard explanation which I can accept, is as wolves in a grassy areas, this action made a nice bed. I view it as pure instant , and my dogs never knew why they did it. They do understand some things. He just came to me and danced expectantly. I knew he hadn't been out in a while. He purposely danced and stared, because he has established a body language communication with me. We went out and the first think he did was pee. I agree he showed intelligent purpose. But he only has a minor degree of that, compared to me. So back to cells: they have no degree of cognitive understanding and therefore reacting with what looks intelligent but all they are doing is following an intelligent designed response to a stimulus.

DAVID: Which is only their stated opinion , but never proof or fact, based on their studies which I have reviewed. Cells are automated factories, which is all they have shown.

“Cells are automated factories” is neither proven nor factual: it is your stated opinion.

Clever Corvids: estimating weight after training
by David Turell , Wednesday, January 09, 2019, 21:48 (2145 days ago) @ David Turell
They were trained to recognize heavy or light:
"A team of researchers with members affiliated with the University of Auckland, the University of Cambridge, Bertha von Suttner University and the Max Planck Institute for the Science of Human History has found evidence that suggests New Caledonian crows can infer the weight of an object by watching how it behaves in the wind.
***
"Humans can easily gauge the weight of objects by their behavior under windy conditions. In breezy conditions, a napkin will fly off a table at an outdoor café, for example, but a fork generally will not. We prepare for this eventuality by placing something heavy on the napkin, but not on the fork. But until now, no other creature has been found to have this ability.
"To find out if New Caledonian crows might have this ability, the researchers went out into the wild and captured 12 specimens and brought them back to their lab. All of the birds were taught to use the weight of an object as the criteria needed in order to receive a food reward. Half were taught that the lighter of two objects was needed, while the other half were taught that it was the heavier object that was needed to get their reward.
"Next, the researchers strung the same objects a few inches off the ground, one by one, and pointed a fan at them to simulate a breeze. The light objects would blow around easily, while the heavy ones remained stationary. The birds were then brought individually into the test area. Each watched as two objects were blown by the fan—the crows were then allowed to pick one of the objects as a means for receiving their treat.
"The researchers report that the birds were 73 percent correct in choosing the object that would get them their reward, all without having touched the objects prior to choosing them. They claim that this very strongly suggests that the birds were able to figure out which of the objects were heavier and which were lighter simply by watching how they behaved under windy conditions."
Comment: Amazing as usual.
Clever Corvids: controlling song calls
by David Turell , Tuesday, August 27, 2019, 19:17 (1915 days ago) @ David Turell
Corvids can be trained to alter calls to respond to stimuli:
https://phys.org/news/2019-08-crows-consciously.html
"Crows can voluntarily control the release and onset of their calls, suggesting that songbird vocalizations are under cognitive control, according to a study...
"In the new study, Brecht and colleagues directly tested the idea that songbirds deliberately control their calls, in the sense that they can be emitted or inhibited at will, as opposed to being knee-jerk responses to food, mates, or predators.
"The findings show that trained carrion crows (Corvus corone), songbirds of the corvid family, can exert control over their calls in a goal-directed manner. In a detection task, three male carrion crows rapidly learned to emit calls in response to a visual cue (colored squares) with no inherent meaning ("go-trials"), and to withhold calls in response to another cue. Two of these crows were then trained on a task with the cue colors reversed, in addition to being rewarded for withholding vocalizations to yet another cue ("nogo-trials").
"Vocalizations in response to the detection of the go-cue were precise timed and highly reliable in all three crows. The crows also quickly learned to withhold calls in nogo-trials, showing that vocalizations weren't produced by an anticipation of a food reward in correct trials. According to the authors, further work is needed to evaluate the neurobiological basis of such cognitive vocal control in birds.
"'Our study shows that crows can be thaught to control their vocalizations, just like primates can, and that their vocalizations are not just a reflexive response. This finding not only demonstrates once again the cognitive sophistication of the birds of the crow family. It also advances our understanding of the evolution of vocal control.'"
Comment: Amazingly clever as usual.
Clever Corvids: the cortical equivalent in many birds
by David Turell , Thursday, September 24, 2020, 22:28 (1521 days ago) @ David Turell
The Avian equivalent of our brain's cortex does exist:
https://science.sciencemag.org/content/369/6511/1567?utm_campaign=toc_sci-mag_2020-09-2...
"birds, and particularly corvids (such as ravens), are as cognitively capable as monkeys (1) and even great apes (2). Because their neurons are smaller, the pallium of songbirds and parrots actually comprises many more information-processing neuronal units than the equivalent-sized mammalian cortices.
***
"Birds do have a cerebral cortex, in the sense that both their pallium and the mammalian counterpart are enormous neuronal populations derived from the same dorsal half of the second neuromere in neural tube development
***
"In both birds and mammals, the pallium is the population of neurons that are not a necessary part of the most fundamental circuits that operate the body. But because the pallium receives copies, through the thalamus, of all that goes on elsewhere, these pallial neurons create new associations that endow animal behavior with flexibility and complexity. So far, it appears that the more neurons there are in the pallium as a whole, regardless of pallial, brain, or body size, the more cognitive capacity is exhibited by the animal. Humans remain satisfyingly on top: Despite having only half the mass of an elephant pallium, the human version still has three times its number of neurons, averaging 16 billion. Corvids and parrots have upwards of half a billion neurons in their pallia and can have as many as 1 or 2 billion—like monkeys.
"Additionally, it has been known since 2013 that the circuits formed by the pallial neurons are functionally organized in a similar manner in birds as they are in mammals (10). Using resting-state neuroimaging to infer functional connectivity, the pigeon pallium was shown to be functionally organized and internally connected just like a mouse, monkey, or human pallium, with sensory areas, effector areas, richly interconnected hubs, and highly associative areas in the hippocampus and nidopallium caudolaterale. The nidopallium caudolaterale is the equivalent of the monkey prefrontal cortex (10), the portion of the pallium that is the seat of the ability to act on thoughts, feelings, and decisions, according to the current reality informed by the senses.
***
"...the same is true of consciousness: The underpinnings are there whenever there is a pallium, or something connected like a pallium, with associative orthogonal short- and long-range loops on top of the rest of the brain that add flexibility and complexity to behavior. But the level of that complexity, and the extent to which new meanings and possibilities arise, should still scale with the number of units in the system. This would be analogous to the combined achievements of the human species when it consisted of just a few thousand individuals, versus the considerable achievements of 7 billion today".
Comment: We knew birds were smart, and now we know why. Part of me is very interested in the bolded comment at the end. Hominins and homos were in small population numbers before we advanced 50,000 years ago and began to build a large population. This fits Gould's concept of small isolated populations causing rapid or large evolutionary advances. What is weird is that a small population is like to have less mutations than a large population, but large brains appeared anyway. That support the concept of a driving force like God. The other point is it is teh volume of neurons that make a difference. Size, by itself, is not a major guide to brain capacity as the first bold shows.

QUOTE: So far, it appears that the more neurons there are in the pallium as a whole, regardless of pallial, brain, or body size, the more cognitive capacity is exhibited by the animal. (David’s bold)
This is a major factor in the debate between materialism and dualism. Does consciousness/ intelligence/cognitive capacity arise out of the neurons, or do the neurons multiply in accordance with the demands of a conscious intelligence? (NB that does not mean that our fellow animals have the same DEGREE of consciousness/intelligence as ourselves.) Were ancient corvids as intelligent as modern corvids, and did they have the same number of neurons? No way of knowing. What researchers could find out, though, would be whether corvid brains, just like human brains, complexify in response to new requirements (e.g. when they solve specific problems).

This was the point I made about the Cape Verde people developing immunity to malaria. We seem to be in agreement, and this has major implications for the whole of evolution. You had asked why humans evolved while apes remained the same, and I responded that conditions may have forced local groups to descend from the trees while elsewhere the apes lived happy ever after.
DAVID: What is weird is that a small population is like to have less mutations than a large population, but large brains appeared anyway. That supports the concept of a driving force like God.
What is weird is that according to you, the driving force behind corvid intelligence and that of every other form of intelligence was your God's one and only desire to design sapiens intelligence. They were all "part of the goal of evolving humans". I would suggest that in all instances, the driving force was the urge of the cell communities to improve their chances of survival by using the intelligence your God may have provided them with from the beginning.
DAVID: The other point is it is teh volume of neurons that make a difference. Size, by itself, is not a major guide to brain capacity as the first bold shows.
Just to link this to our "brain expansion" thread: there is a limit to the number of cells each skull can contain. A corvid presumably wouldn’t be able to fly if its head doubled in size, and so I have proposed that the human skull eventually stopped expanding because further expansion would have created problems for the rest of the anatomy. For other implications concerning volume, see my first comment above.

Based on corvid brain size and what they can do, as I think with humans, a slight skull enlargement is anatomically possible but not necessary because the current brains work so well. Your harping on skull size is a side issue. Neanderthal skulls were much bigger and our earlier brains were also larger. So what!

We agree that the soul can only work with the brain it is given. But that should not stop the soul from using the information provided by the brain to think of new concepts. And yet you say that the “level of MENTAL complexity (i.e. non-material thought) is based on the number of neurons and their networks complex design” (i.e. the material brain). As I understand it, dualism entails the soul doing the thinking and the brain providing the information and implementing the thought. This is what I believe you agreed in the past.

You keep repeating this, and I keep asking why an all-powerful God with only one purpose (H. sapiens) directly designed millions of now extinct non-human life forms, natural wonders etc. before even starting on directly designing all the different stages that led to the only life form (plus food supply) that he wanted to design. Back to “Back to David’s Theory…” Once again: how does the fact that bacteria morphed into apes, dinosaurs and the duck-billed platypus prove that they were all “part of the goal of evolving humans”?

We don’t “know” that bacteria or cells follow exact instructions from your God. We know that they perform all kinds of actions successfully, and it is impossible not to believe that these result from some form of intelligence. You claim the intelligence is in the form of instructions from God, and I propose that they work out solutions for themselves, and whatever mechanism it is that enables them to “think” passes instructions to the rest of the cell.

My agnosticism is totally irrelevant, and I wish you wouldn’t keep using it as your escape route. It is perfectly possible to believe in a God who endowed cells with intelligence.

Back to “Back to David’s Theory…” Once again: how does the fact that bacteria morphed into apes, dinosaurs and the duck-billed platypus prove that they were all “part of the goal of evolving humans”?
Because that is what history of evolution shows us. God creates history.
QUOTE: "With our study we show that cognitive abilities cannot be generalized, but that species instead differ in domain-specific cognitive skills…"dhw: The bold is an important observation in the context of my speculations about evolution and intelligence. Firstly, there are different types of intelligence, and the fact that ants, for instance, only have tiny brains does not mean they do not have the intelligence to work out their own strategies for survival. But I would go even further. Bacteria and other single cells don’t have brains at all, but as you know, I propose that they do have intelligence, i.e. that somewhere within that tiny space is the equivalent of a brain. And that would explain how single cells can also differ in “domain-specific cognitive skills”.
DAVID: We haven't seen bacterial brains as yet with the finest of the newest technical methods but we can follow individual molecules as they work within systems, and we know whole bacteria or cells follow exact instructions for the processes or how they respond to stimuli, all from information in the complexity of the genomes that we are still unearthing. They simply look intelligent and that is all we know at the moment.
dhw: We don’t “know” that bacteria or cells follow exact instructions from your God. We know that they perform all kinds of actions successfully, and it is impossible not to believe that these result from some form of intelligence. You claim the intelligence is in the form of instructions from God, and I propose that they work out solutions for themselves, and whatever mechanism it is that enables them to “think” passes instructions to the rest of the cell.
It is perfectly possible to believe, as I do, that cells follow explicit intelligent instructions implanted by/from God.
DAVID: domain-specific cognitive skills are just that for cells and whole organisms as we observe. It does not mean they use their own innate intelligence or are subject to intelligent information instructions. I believe the latter and you the former. That will not change as long as you remain agnostic.dhw: My agnosticism is totally irrelevant, and I wish you wouldn’t keep using it as your escape route. It is perfectly possible to believe in a God who endowed cells with intelligence.
It does play a role. I deal in absolutes from the evidence and you in possibilities, a vastly different approach.

dhw: […] you say that the “level of MENTAL complexity (i.e. non-material thought) is based on the number of neurons and their networks complex design” (i.e. the material brain). As I understand it, dualism entails the soul doing the thinking and the brain providing the information and implementing the thought. This is what I believe you agreed in the past.
DAVID: The key is implementation, as provided by the available complexity of the neuronal networks which allow the breadth of new thought by the soul.
You are reverting to your old fudge. We are talking about the functions of the dualist’s soul and brain. 1) The soul does the thinking. 2) The brain provides information and implements thought. Simple question for you: is the dualist’s soul capable of thinking new thoughts, using the information provided by the brain?
DAVID: Apes survived just fine without morphing into our big brains.
dhw: And bacteria survived just fine without morphing into apes and dinosaurs and the duck-billed platypus. How does that prove that every organism that ever lived was “part of the goal of evolving humans”?
DAVID: Because that is what history of evolution shows us. God creates history.
Yes, if God exists, he has created history. I’ll leave out apes and living species to prevent any digressions here. The history of evolution shows us that dinosaurs and the dodo existed. Now please tell us how the history shows that (a) your God directly designed them all, and (b) that his sole purpose in designing them was to design H. sapiens, and (c) why God could not have designed H. sapiens without designing dinosaurs and dodos first.

Absolutely nothing to do with my agnosticism. An agnostic is just as free to speculate on these matters as a theist, and in any case I very much doubt that all theists share your views on the nature, purpose and methods of their God.

But you reach definite decisions and talk of absolutes, even though you can’t find ANY logical reasons why he would have applied your choice of his method to fulfil your choice of his purpose. Furthermore, you reject my alternative possibilities, even though you can understand their logic. I know of atheists whose approach to these subjects is very similar to yours.

He wanted to design all of evolution, as history shows with humans as the endpoint. He understood the whole bush of life is necessary as a food supply for all. Especially with the ever rising size of the human population.

We both know no one can read the mind of God. Since He is capable of direct creation of the universe with the Big Bang, it seems He could have created humans directly, but we know He didn't. The food supply is one major reason why not. You rigidly can't make a choice when choices are obvious, and I rigidly stick to my choices all based on reasonable evidence. There is your word.

dhw: Ah, so when you say he thinks as we do, all you mean is that he has got a mind. Got it! Unfortunately, that doesn’t help us to find a reason why he would directly design the dinosaur and the dodo when all he wanted to design was us.
DAVID: He wanted to design all of evolution, as history shows with humans as the endpoint. He understood the whole bush of life is necessary as a food supply for all. Especially with the ever rising size of the human population.
Why were 3.X billion years’ worth of food supplies for millions of now extinct organisms necessary in order to feed humans who had not yet appeared on the planet?
DAVID: No one can know God's exact thoughts. We both interpret the results of God's actions very differently.
dhw: But you reach definite decisions and talk of absolutes, even though you can’t find ANY logical reasons why he would have applied your choice of his method to fulfil your choice of his purpose. Furthermore, you reject my alternative possibilities, even though you can understand their logic. I know of atheists whose approach to these subjects is very similar to yours. They reach a definite decision concerning God’s existence and refuse to listen to your cogent and logical arguments- for design. Can you think of a word that describes this
approach? {Sadly you didn’t come up with one!]
DAVID: We both know no one can read the mind of God. Since He is capable of direct creation of the universe with the Big Bang, it seems He could have created humans directly, but we know He didn't.
And that is your problem. It is not unreasonable to assume that your God, if he exists, did what he WANTED to do. He didn’t directly create humans. So maybe he DID want to create humans, but didn’t know how to do it. Or maybe when he started the process of evolution, it was NOT because he wanted to create humans – but maybe he WANTED to create an ever changing bush of life.
DAVID (transferred from the “error” thread): Your thinking finally understands my theory. Of course He wanted all of the evolutionary stages on the way to humans, which are His final goal. The lack of understanding all these years shows your basic bias from the beginning. Your statement that He only wanted humans was your rigid misinterpretation of my thoughts all along.
But I keep asking you how the dodo and the dinosaur plus millions of extinct life forms can be called stages on the way to humans, in the sense that they were all “part of the goal of evolving humans”. You have consistently argued that your God’s purpose in creating life was to create H. sapiens. Sometimes you dilute this to “prime purpose” or “a goal” instead of “the” goal, and when asked what other goals there might be, you come up with none. I am proposing that the ever-changing great bush of life is what your God WANTED. And although I also propose that the bush is the result of him not wanting a predictable show (hence organisms having a free rein), your own belief that he specially designed every extinct non-human organism renders your anthropocentric theory even less likely.
DAVID: You rigidly can't make a choice when choices are obvious, and I rigidly stick to my choices all based on reasonable evidence. There is your word.
There is no “obvious” theistic choice, because as you rightly say, nobody can read your God’s mind. You rigidly stick to your one choice, and can't find any reason for it except that all the extinct life forms were necessary to feed humans who didn’t yet exist. “Reasonable evidence”?

You are still actively trying to twist an interpret action of my thoughts about God as an excuse for years of your confusion. I answered all your questions over and over in the same tone and fact. Evolving through all the stages of evolution, as history presents, to an accepted goal is a simple concept. That is all I have ever tried to present. Your so-called alternate goals interpret a God with a personality I do not accept. I'm still with Adler's interpretation.
DAVID: You rigidly can't make a choice when choices are obvious, and I rigidly stick to my choices all based on reasonable evidence.

There is a constellation of many facts covered in both my books which help describe God's actions and his probably purposeful personality. The bold is pure nonsense. Extinct life plays no role in current time. The huge bush of life is in present time for our huge population to use now. My God plans for future needs. You mind isn't following the continuity of His purposes. Again your bias, in my view.
Clever Corvids: now New Zealand robins show memory
by David Turell , Wednesday, February 19, 2020, 18:22 (1739 days ago) @ David Turell
All animals with a brain and some even without can be trained. These robins show training memory over a period of time:
https://www.the-scientist.com/news-opinion/wild-birds-remember-a-novel-task-for-nearly-...
"New Zealand’s North Island robins (Petroica longipes), known as toutouwai in Maori, are capable of remembering a foraging task taught to them by researchers for up to 22 months in the wild, according to a study published on February 12 in Biology Letters. These results echo the findings of a number of laboratory studies of long-term memory in animals, but offer a rare example of a wild animal retaining a learned behavior with no additional training.
***
"In the new study, Shaw and her coauthor, Annette Harvey, tested 32 of the initial 64 birds that were trained in 2015 and 2016 and banded for individual identification, 30 of which performed the memory task by spontaneously pecking the lids and opening them on their first try. None of the trained birds had seen the box between the initial training and retesting, though some of the untrained control birds had encountered the apparatus in a previous research project. The time between when the birds had first learned the lid-opening behavior and subsequent testing ranged from 10 to 22 months. By contrast, the 17 untrained birds were unable to complete the task.
"According to Shaw, the two outliers that didn’t remember the task may have been exceptions to the rule. One of the trained birds was a female that had taken the longest to initially learn the task, and whose dominant male partner interfered with testing. The other bird was old and unwell, and disappeared a few weeks after the experiment.
"While Shaw was impressed by her subjects’ performance, Pravosudov says, “I’ve been studying these questions for a long time. It’s not surprising.” Nevertheless, he adds, “it’s good to have more evidence accumulated that the animals are capable of this.” For instance, he cites lab studies that have shown pigeons’ ability to remember and identify photographs and drawings for more than 730 days, and tortoises’ ability to retain an operant conditioning task for nine years. Lab research on Clark’s nutcrackers and chickadees has also found that the birds can remember the locations of hundreds of seeds for six months or more.
“'All animals have some basic memories,” he says, “and we may underappreciate how good . . . even [basic] memory is.'”
Comment: It appears all animal brains have the capacity of memory. It is an important way to remember where fresh food or stored food. All animals must have energy to eat to survive.
Clever Corvids: as smart as apes
by David Turell , Thursday, December 10, 2020, 22:31 (1444 days ago) @ David Turell
A new study with ravens:
https://www.scientificamerican.com/article/young-ravens-rival-adult-chimps-in-a-big-tes...
"Scientists and casual observers alike have known for years that ravens and their corvid relatives are extremely smart. But most studies use single experiments that provide a limited view of their overall intelligence. “Quite often, in single tasks, you’re just testing whether the bird can understand that you’re hiding something,” says Simone Pika, a cognitive scientist at Osnabrück University in Germany.
"A new study that that tries to address that deficit provides some of the best proof yet that ravens, including young birds of just four months of age, have certain types of smarts that are on par with those of adult great apes. The brainy birds performed just as well as chimpanzees and orangutans across a broad array of tasks designed to measure intelligence. “We now have very strong evidence to say that, at least in the tasks we used, ravens are very similar to great apes,” says Pika, lead author of the study. “Across a whole spectrum of cognitive skills, their intelligence is really quite amazing.” The findings, published in Scientific Reports, add to a growing body of evidence indicating that impressive cognitive skills are not solely the domain of primates but occur in certain species across the animal kingdom."
Comment: No surprise based on previous studies.
Clever Corvids: other birds braininess

Broken wing tactic:
https://phys.org/news/2022-03-broken-wing-tactic-widespread-thought.html
"A team of researchers from the Max Planck Institute for Ornithology and California Polytechnic State University, has found that the broken wing tactic used by some birds to lure predators away from their nest is more widespread than previously thought.
"Biologists have known about the broken wing tactic for more than 100 years, but its extent has never been thoroughly studied. What is known is that many members of bird species feign injury when predators approach their nest, hoping that they will be followed. Once they are a safe distance from the nest, the bird flies to safety.
"The work by the team involved searching for papers written about the broken wing tactic using Web of Science, Google Scholar and the Handbook of Birds of the World and building a database of findings. They carried out filtered requests that highlighted information about the tactic and found that it is more widespread than previously known—they found it in 52 bird families (and 13 orders) in nearly 300 species. They suggest this finding indicates that the tactic evolved independently multiple times.
"The researchers then looked for characteristics of the birds that use the tactic to see if they could spot commonalities. They found eight variables that they could associate with the broken wing tactic or feigning an injury. Most notably, they found that it was more common as species lived farther from the equator, suggesting that the behavior was related to shorter incubation periods. They also found it was more common in dense environments and where there was relatively little ground cover to hide the presence of a nest."
Comment: apparently an easily learned and copied tactic.
Clever Corvids: understanding probability
by David Turell , Friday, July 07, 2023, 17:46 (505 days ago) @ David Turell
Latest study:
https://www.newscientist.com/article/2381335-crows-can-understand-probability-like-prim...
"Crows can make decisions according to the likelihood of getting a reward – a cognitive feat known to mathematicians as statistical inference, and rarely found outside of primates.
***
"Her team trained two carrion crows (Corvus corone) to peck at nine, different-coloured symbols to receive a reward: a small food pellet or worms. Over hundreds of trials, they were taught that each symbol was associated with a different probability of receiving a reward, ranging from 10 to 100 per cent per peck. The crows were given the chance to choose between two options: for example, the green circle with a 90 per cent chance of receiving a reward versus the blue square with a 70 per cent chance. There were no wrong answers, just less optimal ones.
"Both crows pecked on the shapes with the highest probability of yielding them a reward more than seven times out of 10. In a second part of the experiment, shapes with lower probabilities were shown more often. While the crows could have pecked them more times and still gotten the same amount of reward, they still chose the shapes with the higher probability of getting them a treat.
“'They knew that even though it was shown less often it was more valuable,” says Johnston.
"This suggests the crows have the ability to use limited information about the probability of something happening and apply it in a new situation to maximise the possibility of getting a reward, she says.
"When tested a month later, the crows made decisions to peck the shapes with higher or lower probabilities at the same rate. “That’s pretty incredible,” says Johnston.
***
"Studies have suggested crows can grasp the concept of zero as a numerical quantity, something most human children don’t learn before around age 3.
"Rakoczy says that, prior to this, such complex numerical abilities were primarily known in primates. This not only highlights how brains can be very physiologically different and still carry out similarly complex reasoning, but also how the latter has cropped up independently in completely different branches of the evolutionary tree, he says."
Comment: more of the same. The crows' neurons are programmed to handle this.
Clever Corvids: more song calls more problem solving

And bigger brains:
https://www.sciencemagazinedigital.org/sciencemagazine/library/item/15_september_2023/4...
"Complex vocal learning, a critical component of human spoken language, has been assumed to be associated with more-advanced cognitive abilities. Tests of this hypothesis between individuals within a species have been inconclusive and have not been done across species. In this work, we measured an array of cognitive skills—namely, problem-solving, associative and reversal learning, and self-control—across 214 individuals of 23 bird species, including 19 wild-caught songbird species, two domesticated songbird species, and two wild-caught vocal nonlearning species. We found that the greater the vocal learning abilities of a species, the better their problem-solving skills and the relatively larger their brains. These conclusions held when controlling for noncognitive variables and phylogeny. Our results support a hypothesis of shared genetic and cognitive mechanisms between vocal learning, problem-solving, and bigger brains in songbirds.
***
"Spoken language and problem-solving are often considered to be components of intelligence in humans. An essential and specialized component of spoken language is vocal production learning, or the ability to imitate sounds. Advanced vocal learning has been found in only a handful of taxa, including five mammalian (humans, elephants, cetaceans, pinnipeds, and bats) and three avian (songbirds, parrots, and hummingbirds) clades. Interestingly, the vocal learning taxa that display the most complex vocal learning behavior overlap with those long thought to exhibit more-intelligent cognitive capacities [e.g., humans, cetaceans, elephants, corvid songbirds, and parrots], although this has not been quantitatively tested across species."
Comment: human brain evolution with enlargement and then the development of language suggests a parallel to the avian discoveries. More vocalizations carrying information require the presence of a larger, more complex brain. The evolutionary human pattern of a large, very complex brain before language development suggests the same pattern of evolution occurred in birds. This supports my view that speciation includes preparations for future important developments within species lifetime.

"According to a new Science study, songbirds that can fluently imitate sounds they hear have bigger brains and better problem-solving abilities than their less tuneful peers.
"This ability to hear and then mimic complicated sounds, called complex vocal learning, is an important part of human spoken language acquisition that has only been observed in a handful of other species. Scientists have long assumed that it is associated with more advanced cognition. So to test this theory, researchers performed a series of behavioral tests on 214 birds from 23 different species. In one experiment, the birds were evaluated on their ability to remove a lid from a plastic container that held a tasty reward. In another, the birds needed to differentiate between lids of different colors to complete the task. The researchers found that species with more complex vocal learning abilities, such as the tufted titmouse, consistently aced the tests. The hapless mourning dove, meanwhile, was unable to perform the lid-opening task even after more than 50 attempts." (my bold)
Clever Corvids: crows count outloud
by David Turell , Friday, May 24, 2024, 16:05 (183 days ago) @ David Turell
Latest story:
https://www.sciencealert.com/crows-can-actually-count-out-loud-amazing-new-study-shows?...
'A team of scientists has shown that crows can 'count' out loud – producing a specific and deliberate number of caws in response to visual and auditory cues. While other animals such as honeybees have shown an ability to understand numbers, this specific manifestation of numeric literacy has not yet been observed in any other non-human species.
"'Producing a specific number of vocalizations with purpose requires a sophisticated combination of numerical abilities and vocal control," writes the team of researchers led by neuroscientist Diana Liao of the University of Tübingen in Germany.
"'Whether this capacity exists in animals other than humans is yet unknown. We show that crows can flexibly produce variable numbers of one to four vocalizations in response to arbitrary cues associated with numerical values."
"The ability to count aloud is distinct from understanding numbers. It requires not only that understanding, but purposeful vocal control with the aim of communication. Humans are known to use speech to count numbers and communicate quantities, an ability taught young.
"When toddlers are learning to count, learning the specific numbers associated with specific quantities can take a bit of time to master. In the interim, children can sometimes use random numbers to make a vocal tally. Instead of counting "one, two, three," they might say "one, one, four," or "three, ten, one." The number of vocalizations is correct, but the words themselves are jumbled.
***
"All three crows, the researchers found, were able to produce the correct number of caws in response to the cues, with the occasional error mostly presenting as one caw too many or too few.
"This, the researchers say, is similar to the way human toddlers count, using a non-symbolic approximate number system that is planned in advance before the first vocalization.
"Interestingly, the timing and sound of the first vocalization in a sequence were linked to how many vocalizations were made subsequently, and each vocalization in a sequence had acoustic features specific to its place in that sequence.
The feat is especially impressive for crows since deliberate vocalizations are more difficult to produce and have longer reaction times than, say, pecks or head movements.
***
"'This competency in crows also mirrors toddlers' enumeration skills before they learn to understand cardinal number words and may therefore constitute an evolutionary precursor of true counting where numbers are part of a combinatorial symbol system.'"
Comment: What this shows is that it doesn't take too many neurons to mimic human capacities.
