Document Summary

5 to 8 months of age, respond to parents" words. Early vocabulary simple e. g. nouns (mama, duck) Likely to contain objects that infant can manipulate ( ball more likely than ceiling ) Difficult to tell what kids mean when the use single words. By 2 years old child moves beyond 2 words, and sentences become more complex. The 4 or 5 year old makes mistakes in tense e. g. runned not ran , eated not ate . So far, it seems as if the brain is hard-wired for language. Will language develop on its own : wild children. Consider amala (1. 5 years) & kamala (8 years: isolated children. Genie (14 year old) no: no models e. g. deaf kids with hearing parents who do not sign. Seems unlikely given data on wild & isolated children. Even with innate abilities, experience may be critical at a particular developmental phase. e. g. white-crowned sparrow. Must be exposed to adult song 7th-60th day of life.
