This study investigated questions asked during two types of mother-child interaction and demonstrated ways in which mother-child dyads may structure their interactions differently in different settings. Participants were 16 first-born girls between 2.5 and 3.5 years of age who were videotaped on four occasions when they played in their home for 15…

This study examined transcripts of 63 mealtime, dyadic interactions of mothers and their children. An earlier investigation of the effects of social class and communicative setting on maternal speech found a significant class difference and within-class variability in the amount of speech mothers directed to their children. There were significant…

A study attempted to determine dimensions of maternal adaptation of language to the level of their young children's speech, and whether patterns of maternal adaptation can be described as interactive maternal styles. Links were sought between aspects of maternal language adaptation and child language level. Participating were 6 mother-child dyads…

Early interventionists are accountable for the progress of children receiving their services. Technically adequate measures of the progress of individual children are needed. While the Early Communication Indicator (ECI) for infants and toddlers is one such measure, data to support its use are limited to a single research report. In this…

Investigates differences in the language learning environments of six twin pairs and 12 singleton toddlers (all firstborn) with special reference to pragamatic factors that might be expected to differ in dyadic and triadic interactive situations. (HOD)

The purpose of this study was to measure fathers' and mothers' linguistic involvements with the development of communication between young siblings. A total of 39 2-parent families with 2 children were videotaped in semi-structured activities in a laboratory setting. The older sibling was from 18- to 26-months-old and the younger was from 4- to…

Two longitudinal studies focused on naturally occurring conversations at home among (1) 18- and 24-month-old second-born children, mothers, and older siblings, and (2) first-born children 25 and 32 months old, mothers, and younger siblings. By two years of age most children referred to a range of feeling states in self and other, and discussed the…

Compared comprehension of novel communicative signs to assist 2.5- and 3-year-old humans, chimpanzees, and orangutans find hidden objects during a hiding-finding game. Found that children at both ages performed above chance with all signs. No ape performed above chance for any signs not known before the experiment despite three times as many…

Investigates conversational characteristics (discourse features, illocutionary force and style parameters) of mothers of two-year-old twins and mothers of two-year-old singletons with older siblings. Finds significant differences in conversational characteristics, and between twins' and singletons' language scores on measures of language…

This research review sought to discover the forms of family verbal interaction that nurture language development in infants and toddlers, the function of different family members in this process, and the role of environmental factors in language development. Results indicate that speech to a child is significantly different from speech to an…

Addressing methodological limitations, Study One compared parent-child interactions of normal and language-delayed children; Study Two investigated whether mothers adjust the length of their utterances to the child's ability to comprehend or to produce language; Study Three probed interactional variables associated with variations in the…

This longitudinal, ethological study explores the development of communication behaviors, different types of social peer interactions, and mother-child interaction among 15 boys and 15 girls from 16 through 30 months of age. Each subject was filmed twice each month over a period of 14 months while he or she had lunch with 5 peers. Several subjects…

Communication between parents and staff was observed in 16 proprietary day care centers during morning and afternoon transition times when parents dropped off children and picked them up. Results revealed large, stable differences among centers in the frequency and usefulness of these exchanges. About two-thirds of transition time opportunities…

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…

Relationships between the function and content of maternal interventions to control their toddlers' behavior and behavior problems and compliance in the child's fifth year were studied. Naturalistic observation of 51 dyads consisting of depressed and nondepressed mothers and their children who were 1.5 to 3.5 years old at the time of first…
