How children pick up a language: defending Chomsky (Humans)

This is an article that defends his point of view, that children have an innate ability to pick up language and grammar:-http://www.medicaldaily.com/noam-chomskys-theory-universal-grammar-right-its-hardwired-our-brains-364236-"In the 1960s, linguist Noam Chomsky proposed a revolutionary idea: We are all born with an innate knowledge of grammar that serves as the basis for all language acquisition. In other words, for humans, language is a basic instinct. The theory, however, has long been met with widespread criticism — until now. A new study presents compelling evidence to suggest Chomsky may have been right all along.-***-"Although humans learn by example, he proposed that we are all born with a fundamental understanding of the underlying mechanisms of language. Chomsky's original work, called universal grammar, is the reason why humans can recognize grammatically correct yet nonsensical phrases, such as “colorless green ideas sleep furiously.” Past research has shown our ability to distinguish words from nonwords even without an understanding of the language, is a skill that even non-verbal babies possess. Researchers have long failed to prove this same instinctual knowledge also exists for grammar.-***-"researchers from New York University recently used new technology to prove Chomsky's theory may have been factual all along (not unlike these other scientists whose ideas were ahead of their time).-"For the study, the team recruited volunteers to listen to word phrases spoken in both English and Mandarin Chinese, including predictable sentences like “New York never sleeps,” grammatically correct yet less predictable sentences like “Pink toys hurt girls,” and word lists like “eggs, jelly, pink, awake,” a press release reported. These sentences were specifically designed so all obvious indications of grammar, such as voice intonation cues, were missing. This ensured the only indication of grammar would come from the subjects' own minds, not the sentences themselves.-***-"As subjects listened on, researchers measured their brain activity using two tools: magnetoencephalography and electrocorticography. The first measures tiny magnetic fields created by brain activity and the second measures brain activity in patients undergoing brain surgery.-"Results revealed brain activity changed depending on whether the volunteers had listened to a sentence, a phrase, or a word list. This showed that the subjects were able to process the grammar minus the obvious learned cues. "Because we went to great lengths to design experimental conditions that control for statistical or sound cue contributions to processing, our findings show that we must use the grammar in our head," explained researcher David Poeppel in the release.-"According to Poeppel, our brains lock onto every word to comprehend phrases and sentences. He said, “The dynamics reveal that we undergo a grammar-based construction in the processing of language.”-"In an email to Medical Daily, Poeppel explained that although it is difficult, if not impossible, to prove theories, the data ascertained in his research supports crucial aspects of Chomsky's theory, namely that listeners build abstract, hierarchical constituent structures of linguistic information.-“'I'd say, on balance (comparative language research, language acquisition research, these kinds of brain data) the empirical research favors the Chomskyan view, as unpopular as it is,” Poeppel wrote-"Poeppel also recognized the controversy in his finding, seeing as the preferred view is that grammar is achieved by using acoustic cues such as intonation, and statistical cues, like word transition.-“'However, we demonstrate that linguistic structure building happens in absence of those cues — so grammar based structure building must exist,” Poeppel said. “That is, in brief, the controversy.'”-Comment: No doubt the theory is still very controversial. Why do babies distinguish between words and non-words? It seems something is preset in the babies' brains. Also children learn a second language without any accent until about age eight. After that an accent from the initial language tends to appear. What does that mean about the early brain? Does it lose language ability as it ages?
