Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

Examines the effects of chronological age, mental age, and intelligence quotient on verbal imitation of five-year-old children, concluding that transition occurs during the fifth year of life as young five-year-olds emitted more mimical and less conceptual responses than older five-year-olds. (RB)

A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

The use of the verbs "go" and "come" was examined in the spontaneous speech of seven two-year-olds. As verbs of motion, the words were used in the context of describing the contour of movement rather than as means of relating end-points of a journey. This is considered crucial in explaining children's difficulty in discriminating the verbs in…

Case studies of a few naturally bilingual children are reported in the context of a larger research project with bilingual children living in Rome. Studies focused on personality traits present from birth and concomitant with bilingual development. Data confirm full psychological normality on the part of bilingual children. (Author/AMH)

This paper discusses C. Chomsky's 1969 paper on children's syntactic development and the subsequent studies made to test her findings. Later studies indicate that Chomsky's results were not clearly differentiated, and a slight alteration in procedure changes results significantly. (CHK)

There are problems in interpreting the naming behavior of children. Children may misname a word because the word is absent from their vocabulary, because it is not yet firmly established, or because of a word retrieval or lexical assessing problem. Preliminary results are reported of an experimental technique designed to account for these…

This article reports on a study to determine the role of intonation in language acquisition. Related studies are mentioned. Research methods for the study are outlined and two case studies are reviewed. Conclusions show that adult-child interaction influences not only the child's use of intonation but also his acquisition of syntax. (Text is in…

Vocalizations of two female infants, recorded over a five-week period after the first emergence of cooing were studied. It was found that the features of the more primitive sound types regrouped themselves in comfort sounds. The implications for theories of prespeech development are discussed. (EJS)

The development of plurals in two German-speaking children was analyzed, based on observational data. It was argued that the children were learning plurals by rote, conditioned by morphological complexity which cannot be subsumed under any general rule. (Author/NCR)

Spontaneous full passives and related constructions from 234 children, aged 2 to 13, and elicited passives from 262 college students were analyzed. The agentive non-reversible did not appear until after age 9; and until age 11 no child produced both reversible and non-reversible passives. (Author/SW)

Focus is one factor that may account for children's use of single-word utterances after they have acquired the use of multi-word utterances. The possible role that focus may play in children's use of single-word utterances in naturalistic settings, after the acquisition of syntax, was investigated. (SW)

Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Describes a study that investigates the order of acquisition of case-marked pronouns in Hebrew among 105 children between two and five years of age. Results indicate that children begin using case-marked pronouns as early as age two and that the stage of morphological development parallels that of English-speaking children. (SED)

This study explores children's development of dual-level phonological processing posited by generative theory for adult language users. Evidence suggesting 6-year-olds' utilization of morphophonemic segments was obtained by asking children to imitate complex words, omit specified portions, and discuss the meaning of the resulting word-parts. The…
