Document Summary
Knowledge and abilities acquired without experience are said to be_______ How do newborns know what they need to survive: all species have evolved highly constrained neural mechanisms to ensure that, at least some, environmental info is properly interpreted. Infants learning language: language acquisition involves both, experience independent. Innate: experience dependent, learned, the debate concerns the relative importance of each, young humans, as poor learners, suggest a more important role for innate factors in the acquisition of language. Infants listened longer to the less familiar items: the part-words: 6. 77 seconds for real words, 7. 60 for part-words. Implication: sensitivity to statistical regularities applies across a variety of sensory domains and stimulus formats, this is a general ability that is innate. Is sensitivity to statistical regularities unique to humans: no. Implication: not a uniquely human ability, but there are suggestions that humans can do more with this information than other species are able to, summary.
