This study was designed to answer the following three questions: (1) Are infants' first words always context-bound when they are initially acquired? (2) Do mothers use infants' first words in a context-bound manner when interacting with their infants? (3) What relationship, if any, exists between infants' initial use of early words and mothers'…

An analysis of the speech of infants gives a clue to the evolution of language. (DR)

Four studies examined whether 16-month-olds' responses to true/false utterances interacted with their knowledge of human agents. Findings suggested that infants are developing a critical conception of human speakers as truthful communicators and that infants understand that human speakers may provide uniquely useful information when a word fails…

Notes that Charles Darwin's observations on babies are not examples of data collected to test hypotheses. Draws from Bakhtin to argue that they extend and vary existing modes of discourse, primarily debates about the place of instinct in language acquisition, traceable to his grandfather, Erasmus Darwin. Concludes that the significance of Darwin's…

Infant imitation is considered a significant component of social, cognitive, and language development. Observation of 20 infants and their mothers in 2 naturalistic settings at 4 separate ages revealed dyads' imitation and matching in vocal, verbal and action behaviors. Verbal matching increased over the second year, suggesting relation of dyads'…

The results obtained by researchers interested in the speech-time relationship indicate that the sequential organization through time of speech sounds necessary for communication requires a universal "grammar" consisting of vowel and consonant sequences and an awareness of the duration experienced in that process, as well as the memory…

A research project was aimed at measuring the relationship between infant vocalizations and linguistic development and determining the feasibility of using infant vocalizations as a predictor of later psychological and intellectual status. However, a method was needed to analyze the vocalizations of infants. This report describes a method used to…

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

Reviews new developments in the field of child language acquisition that emphasize the role of communication and dialogue. Mentions work on precursors to dialogue in infancy, the development of communicative intent, and the importance of cognitive over syntactic strategies of language processing by the young child. (Author/SS)

Object play and communication development were studied with four infants with cerebral palsy, involving time spent with objects, types of object play, and object selection. As coordinated looking between object and adult emerged, children demonstrated increased interest in objects and sophistication in their play behaviors. (SW)

A case study of the period of repetitive babbling in one Dutch infant is reported. Repetitive babbling is seen as a systematic and continuous process, during which the child is applying certain strategies in order to form concepts concerning the possibilities of his or her articulatory apparatus. Strategies identified are: (1) variation…

Thirty-one papers and reports dealing with recent work on language input to children are listed in this annotated bibliography. The annotations, which are descriptive rather than evaluative, summarize the design of each study, the nature of the data, and some of the results and conclusions. Entries by P. Broen, J. Bynon, L. Cherry, J. M. Crawford,…

This paper deals with three areas concerning early vocal development: (1) review and critique of existing experimental evidence suggesting that early vocal behavior has the properties of an operant response, (2) speculations concerning the role of non-verbal vocal behavior in early psychological development, and (3) suggestions for future…

Examines the nonverbal communication competence of 18- to 48-month-old Down Syndrome children. Results indicate that Downs children display strengths and weaknesses in nonverbal communication skills. Further, results suggest a deficit in expressive language is associated with a deficit in nonverbal requesting skill that had developed earlier among…
