Document Summary

1: 1950s, cognitive psychologists investigate the complexities of language, inference, problem solving, decision making and reasoning. Outline the development of human language during the first year. 3: 1-5 months- reflexive communication: vocalizes randomly. Coos, laughs, cries, engages in vocal play, discriminates language from non-language sounds: 6-18 months- babbling: verbalizes in response to the speech of others; responses increasingly approximate human speech patterns. Describe children"s early use of single words and word combinations. 10-13 months- most children begin to utter sounds that correspond to words (first words are similar to phonetic form and meaning) 12-18 months- one-word sentence stage: vocabulary grows slowly; uses nouns primarily; overextensions begin. 18 months- can say between 3 to 50 words; receptive vocabulary is larger than productive vocabulary (can understand more than say); words refer most often to objects. 18-24 months- vocabulary spurt: fast mapping facilitates rapid acquisition of new words. 2 years- two-word sentence stage: uses telegraphic speech; uses more pronouns and verbs.
