The current study explored the link between mouthing and fingering and vocal behaviours directed to objects and caregivers. Nine infants were tracked from the ages of 8-16 months by video recording their mouthing and fingering vignettes and vocal behaviours and vocal behaviours resulting in a total of 2,061 coded behaviours. Microanalysis revealed…

Parity is one source of automatic reinforcement that increases the probability of verbal behavior that conforms to models provided by the verbal community. Parity as a conditioned reinforcer could explain the acquisition of grammar in the absence of direct, explicit reinforcement. This possibility has been explored in previous research on…

Restricted and repetitive behaviors (RRBs) are characteristic of autism spectrum disorders (ASD). However, compared to social and communicative impairments, less is known about their development, trajectory and etiology. This study explored RRBs in young children with ASD matched to typically developing (TD) children on non-verbal development.…

Research indicates that deaf individuals do not develop the usual hemispheric specialization for verbal and nonverbal processing and that early severe hearing impairment influences the lateral organization of the brain for interpreting linguistic information. Possible instructional implications include encouraging an early symbol system for…

The development of communication ability between very young children is examined. (JD)

Explored the interplay between gestures and words in the early vocabulary of 12 normally developing Italian children at 16 and 20 months of age. Focused on spontaneous production of verbal and gestural types and tokens to assess the diversity and semantic content of the verbal and gestural vocabularies. Results indicated that gestures were used…

Face-to-face communication makes up only a small proportion of an infant's diurnal transactions with his environment, but it is viewed as crucial to his total development. Research was conducted in which adult and infant behaviors were videotaped, and their interactions were analyzed. (Author/HP)

This study investigated whether mothers' responses to their infants' gestures play a role in their infants' vocabulary development. Eight infants were observed interacting at home with their mothers on 2 occasions, when the infants were 10 to 12 months old, and 16 to 18 months old. Videotapes of the observations were transcribed and coded for…

To study maternal behaviors as related to social class differences, 30 middle class and 30 working class white mothers were observed at home on two separate days with their 10-month-old firstborn baby girls. Predesignated behaviors which occurred during 5-second intervals were recorded by an observer. Total observation time was 4 hours for each…

This study investigated the role of gesture in communication development. Gestural categories, based on communicative function, were identified from longitudinal videotapes of one mother-child pair. The videotapes were made weekly or bi-weekly from the time the child was 13 months of age until she was 42 months of age. The results of the study…

Forty-eight middle-income children, equally divided as to sex, looked at a sequence of animated films in which a pair of male figures underwent a change in facial affect. Three questions were posed: (1) Could a qualitative-structural analysis be applied to the kinds of explanations given by the children to account for changes in facial affect? (2)…

This booklet for parents provides a brief explanation of how babies and young children learn to communicate with others (through actions and words) and suggests specific ways parents can help their children learn to communicate effectively. (RH)

This is a research report on the acquisition and development of language in children from 4 to 6 years as observed in the pre-elementary grades. The research was done by a number of teams scattered throughout France, and this book is a collection of the papers prepared as a result of their research. The report is divided into five sections. The…

A Title I 5 year Visual Literacy Experimental Program was initiated in four kindergarten classes during the 1972-73 academic year. The program was designed to focus on a hierarchy of visual skills and aesthetic experiences involving body language, graphic expressions, and photography, and to correlate these with the objectives of the classroom…

This document reviews a number of recent studies written in French that investigate the nature of communication between 2-year-old infants and others. The review includes three parts. The first part focuses on studies aiming to constitute a behavioral catalog of the child. Characteristically, these studies offer a posteriori interpretations of…
