A phenomenon called "pragmatic variation" is discussed as a child's individual system of behavior in response to a question the child doesn't understand but realizes that he must verbalize an answer to. (NCR)

This report describes an investigation of the acquisition by children of a symbolic system, specifically English nomenclature--that set of nouns that serves the function of naming, denoting, or referring to objects. The five studies involve nine experiments dealing with one or another of the aspects of this problem. Two questions guided these…

The significance of three mothers' speech for their infants' language development is considered in a continuing longitudinal study. The study began when the children (two females and one male) were 5 and 6 months of age and will continue until the subjects are 3 years old. In the speech data reported the children were from 6 to 18 months of age.…

One of the most remarkable aspects of the babbling of some babies is that it is produced with intonation contours that sound very much like adult sentence melodies. This study reviews the literature and examines longitudinal data collected from seven children. Some of the non-adult-like syntactic uses made of intonation by children for…

This guide to a total developmental language program for kindergarten is divided into three sections: (1) Helpful Hints to the Teacher, (2) Expanding Verbal Power, and (3) Linking Language and Thought. Subjects in Section 2 include hearing and speaking clearly, increasing vocabulary, extending meaning, expanding language patterns, conveying ideas,…

A common assumption underlying cross-linquistic studies in child language is that the comparison of any feature in unrelated languages may simplify semantic-grammatical complexities in a way that studies on a single language cannot. This paper begins by discussing the order of acquisition of grammatical morphemes in Spanish by four…

Data from responses to a grammaticality judgement test by 26 learners of English as a second language at two proficiency levels were used to investigate syntactic acquisition. Four syntactic structures were examined. Results suggest that less proficient subjects use syntactic strategies, while more proficient learners use semantic-based…
