Discusses a study of the relationship between context and a mother's speech to her prelinguistic infant and a second phase which involved 48 mothers and their infants. Results are discussed in relation to a hypothesis that assumes that mothers' speech is determined by particular interactive rules operating in the mother-infant dyad. (Author/SED)

The ontogenetic development of human vocal utterances and their role in early interaction processes were studied with a three-month-old baby. Recordings were made of infant vocalizations in the home and the sounds were classified. During a five-minute segment between the mother and infant, the infant produced 59 utterances, 93 percent of which had…

Describes specific changes in children's conversational abilities in early childhood, which may in turn serve to alter how their partners judge their abilities to understand. The evidence regarding the level and types of changes in adult speech to children as the child's ability changes is also addressed. (EJS)

This study investigated the linguistic characteristics of speech addressed to the child and the features of the verbal environment critical for learning language. The study focused on the prosodic and paralinguistic features of adult speech to the young child. Adult speech directed to children was compared to other kinds of systematic speech…

A study examined patterns of development in spoken interaction and types of causal thought that might reflect the human capacity to displace, that is, to shift reference from the present moment to another moment in time. Participants were four infants and their parents, who came to a laboratory for one-half hour every 2 weeks from the child's…

Twenty dyads--ten middle-class mothers and ten lower-class mothers and their two-year-old children--were videotaped in a play situation. Variables in speech and utterance production were examined for change across condition (awareness or ignorance of being observed) and across socioeconomic class within condition. The number of utterances was…

The way that mothers' input assists children with the use of their linguistic resources for negotiating peer interaction was studied. Two two-year-old girls and their mothers were videotaped once a month for eight months while the foursome met at a weekly playgroup. The mothers' language was analyzed in terms of the following questions: (1) Does…

The development of the Conversational Unit (CU) was investigated in a semilongitudinal study of three mother/son dyads in nonstructured spontaneous communication. The children were 19 to 23 months old at the start of the investigation. Sound films were recorded monthly during bathing and feeding times. After four months, verbal and nonverbal…

Features of parental speech to young children was studied in four English-speaking and four Spanish-speaking families. Children ranged in age from 9 to 12 months for the English speakers and from 8 to 22 months for the Spanish speakers. Examination of the utterances led to the identification of 34 prosodic, paralinguistic, and interactional…

Examined 2-year-olds' language acquisition with an emphasis on the agency and intentionality of the child. Concluded that development depends on the child's expression of intentionality by actions (performance), the essential tension between the child's engagement and effort, and the integration of linguistic, cognitive, and social aspects of the…
