Presents a study of the effects of training 18 subjects, 28-40 months, in the use of two-word subject-verb utterances. The study focused on: (1) the number of different semantic relations underlying the subject-verb form in which the child is trained, and (2) the relationship between the semantic relations and ongoing, experimentally manipulated…

The research reported is part of an investigation into the acquisition of grammar, using nonlinguistic information from situational and behavioral context to analyze the development of linguistic expression. Three children were seen for approximately 8 hours, every 6 weeks, in their homes, from the age of 19 months--soon after the earliest…

This review of literature in linguistics and the psychology of language focuses on studies produced from 1961 through 1963. Such topics as language development, generative grammar, semantics, and the role of linguistics in the teaching of reading are covered, and much attention is given to the areas of verbal learning and the psychology of…

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…

This paper proposes a broad outline of a variable model of language development and explores several particulars of such a model in the language behavior of four two-year-old children. The process by which information about language is progressively transformed and integrated rather than merely being added together can be seen in the shifting…
