Two lower socioeconomic groups (one black and one white) from the inner city and a third group of white children from a middle socioeconomic suburban area of Chicago were studied to delineate and compare the usage of selected language structures among children of different social and ethnic backgrounds. Usage of each of the test structures was…

The crib talk reported here of a 2;2-2;4-year-old boy replicates the phenomenon of crib talk reported in previous studies by other investigators. This study adds a corpus of mother-child interaction (MCI) and tests one aspect of the hypothesis that crib talk may enhance production of linguistic forms at a later date. Transcripts of monologues were…

A study was conducted to compare the relative performance on yes-no questions of bilingual and monolingual children and to discuss the relationship of semantic development and linguistic development, both in the bilinguals and monolinguals. Eighteen English monolingual, eighteen Japanese monolingual, and eighteen Japanese-English bilingual…

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…

Investigators agree that mothers employ a variety of request forms and that children seem to be able to respond to these forms with a remarkable degree of accuracy. It is suggested that the speech of mothers to their children is filled with requests which are really not requests at all. It is shown that many of what appear to be adult requests to…

This study proposes that children's phonological behavior at Stage VI of sensorimotor development may show markedly decreased variability compared to children at Stage V. According to Piaget, sensorimotor development during Stage VI is distinguished from preceding stages by the onset of representational ability and ability to form mental…

Similarities and differences in language acquisition and variations in patterns of language dominance were studied with three four-year-old girls. The ideoqraphic study of child speech involved a monolingual English-speaking child, a monolingual Spanish-speaking child, and a bilingual English-Spanish-speaking child. The following measures were…

The acquisition of the consonant system by a child acquiring Mexican-Spanish as her native language is described. During the earliest stages (from 1;7 to 2;1 years of age), the data showed several phenomena that could best be accounted for by assuming a central role for the word as the basic unit being acquired. The evidence for the centrality of…

The purpose of this research was to develop methods to study the effects of context on children's comprehension and production of temporal terms such as "before,""after,""next,""then," and "but first." A longitudinal study, using naturalistic and traditional laboratory methods, and three…
