The antecedents of verbal behavior, together with the teaching skills of the adult linguistic community, probably constitute all the necessary bases for language acquisition. As they seemed to be sufficient for the explanation of all the known phenomena, an assumption of an innate linguistic language acquisition device was rejected as superfluous.…

The hypothesis explains the early lexical development of children and the predictions of this hypothesis are shown to be consistent with available data on overextension. (Author/NCR)

A study examined how preschool children use information about linguistic contrast in learning new words. The 72 subjects were assigned to four groups to play a game. They were asked to get an unfamiliar item, one of nine swatches of different colors, shapes, and materials. In the first group, the children were told only one label (color, shape, or…

Reports on experiments examining the semantic organization of concrete nouns and verbs and its development in childhood. Differences in semantic organization are said to be a clue to age-related changes in performance with verbs. (AM)

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…

Sixty-five grade 5-6 children were tested on a verbal recall task involving material of varying semantic and syntactic content. There was no difference between best and poorest readers in their performance on random lists of words, but there were clear differences on meaningful sentences and on syntactically well-formed but semantically anomalous…

A previous study found that middle-class Hebrew-English bilingual children were characterized by distinctive perceptual strategies and more advanced processing in certain verbal tasks, as compared to similar monolinguals. The present study tested whether similar strategies and response patterns will appear when the children involved are from…
