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…

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…

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…

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 paper by Keenan and Klein (1975) provided evidence for the hypothesis that conversationality is present in children as young as 2 and 1/2 years of age. Results of the study indicated that before the emergence of more adult-like coherency operations, the children passed through a period in which such operations were foreshadowed by vocal play.…

Paralinguistic and kinesic expression begin at birth and are essential to the development of language. Rhythm, for example, a suprasegmental event, appears to be present at birth or prior to birth. The relationship of physiology to communication is evident in the observations of extra-linguistic aspects of communication, such as movement, the use…

Based on research in infant sign language, this book teaches parents methods of communicating with their infants through the use of simple bodily movements that signify objects, events, and needs. Noting that communication between parent and child can flourish between 9 months and 30 months, when a baby's desire to communicate outstrips the…

The effect of children on adult language has only recently received serious consideration in the fields of linguistics, psychology, education, pediatrics and anthropology, although the importance of parental behavior for the language development of the child is universally recognized. This paper presents a review of the literature on children's…

This paper offers some ideas on the types of behavior that can be considered precursors to language and that also lay the foundations for logic, mathematics, physics, etc. The paper posits the problem of whether a theory of language must be formulated before one can formulate a theory of language acquisition, or whether the reverse is true. The…

Literature on the sighted child suggests that blind children might be delayed in language acquisition and/or restricted in the semantic content of their utterances and in the communicative intentions they express. This study questions the use of guidelines appropriate for monitoring sighted children in the study of language development in blind…

A study is reported relevant to the relationship between first words learned by children and gestural symbolization under a variety of contextual conditions. It is part of a larger longitudinal study of 32 children at 10, 13, 20, and 27 months of age. The children were seen in three standardized situations for eliciting gestural and vocal symbols:…

The question is addressed whether a child would develop a communication system if a conventional linguistic model is absent. Six congenitally deaf children, who were not exposed to Sign Language, were observed and videotaped at play in their homes at intervals of one to three months. The children ranged in age from 1 year, 5 months to 4 years, 1…
