This chapter, to be included in "Carmichael's Manual of Child Psychology," edited by P.A. Mussen, deals with the connection between the acquisition of language and the growth of intellect, and the connection between both of these and the process of maturation. The author feels that various theories of development cannot account for the child's…

The verbal behavior of three children was sampled. The samples were analyzed to obtain a picture of three stages of the children's language development, specifically the interrogative structures. Each stage was about 4- or 5-months long, starting at the 18th to 28th month, depending upon the child's level of linguistic ability. The interrogative…

From the standpoint of transformational grammar, this experimental work evaluates the extent to which children choose or fail to generalize their rules for the placement of the negative particles "not" and "n't." The subjects were eight three- and four-year-olds of middle-class background who had been producing sentences with…

A study was undertaken to determine whether children in early periods of language development use stress with any regular patterns, and if so, on what the patterns are based. The subjects were five children aged 21-29 months, MLU between 1.3 and 2.4. Tape recordings were made during play sessions with each child. Two-word utterances that could be…

The syndrome of childhood autism is typified by major abnormalities in language development, yet there are few systematic descriptions of autistic children's linguistic systems. This paper represents the beginning of a comprehensive investigation of the language of verbal autistic children and concentrates on comparing the syntax used by ten…

This investigation studied the development of the form and function of negative sentences, and how it relates to the input on negation that children receive from their parents. The data came from three children: two from a previous study (Bellugi) and one the son of the investigators. A detailed analysis was carried out of the syntactic form and…

This study considers the interaction of syntactic and pragmatic factors (social and cognitive) in children's production of coordinate structures involving conjunction reduction. Two aspects of pragmatic context were considered: (1) the pattern of uncertainty or redundancy in a complex action sequence, and (2) the perceptual grouping of objects…

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…

The experiment described in this report investigates second language development and the possibility of determining various levels of language acquisition. The subjects involved are Japanese students learning English. The students are given the task of recalling English kernel sentences after hearing them once. The resulting sentences--the…
