The linguistic interactions in the speech of bilingual children is systematically examined to determine their ability to differentiate between their two language systems. The speech samples of eighteen bilingual (Spanish-English) children aged two to six were examined for instances of deviation from the norms of the language of utterance due to…

The French gender usage of grade two and grade five Franco-Ontarian children was compared with that of English-speaking children enrolled in French immersion programs, and monolingual French-speaking children in Quebec. While some of the Franco-Ontarian children are similar to the Quebec children with respect to the gender "rules" they…

The research reported here was carried out to help establish the normal course of fricative acquisition as a basis for comparisons with abnormal development. Three questions concerning phonological processes were investigated as part of a larger study of fricative acquisition: (1) the phonological processes that underlie children's fricative…

The key ideas developed by the Writing across the Curriculum Project begun at the University of London in 1965 center on the ways in which discourse is acquired by children in a psycholinguistic sense. Among those ideas are (1) knowledge is socially determined through the interweaving of individual consciousnesses, each of which is busy construing…

Sound play is important to child language development in that it contributes to the phonetic substrate, it is a factor in phonological development, and it is something to be learned as part of the socially acceptable use of language. Sound play progresses in three stages: (1) babbling, in which a gradual acquisition of phonetic units is built up…

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…

A study was conducted to analyze the language behavior of mothers of children with normal language development and mothers of children with delayed language development as they interacted with their children to determine if the two groups of mothers provided different linguistic inputs for their children. Two randomly selected groups of children…

Four problems in children's paired-associate memory were addressed: (1) reappraisal of the presumed developmental trend in presentation mode effect during grade-school years, (2) identification of the locus of this developmental effect, (3) evaluation of the influence of combined presentation (verbal plus pictorial) relative to pictorial…

The experiment reported here attempted to investigate the nature of both intrinsic, unlearned temporal parameters as well as learned, language-specific durational properties in the speech of young children. Developmental aspects of several temporal parameters were investigated in the speech of ten 2 1/2 to 3-year-old and ten 4 to 4 1/2-year-old…

The years after children demonstrate comprehension of particular syntactic structures have received little attention. What happens in language development after mastery is achieved? Are children then like adult speakers in judging the acceptability of grammatical structures? Questions addressed in this research were: Will older children and young…

This paper reports on a longitudinal study of the acquisition of the voicing contrast in English word-initial stop consonants, as measured by voice onset time. Four monolingual children were recorded at two week intervals, beginning when the children were about 1;6. Data provided evidence for three general stages: (1) the child has no contrast;…

This paper discusses the nature of language knowledge and the manner in which children come to acquire this knowledge. Among the topics discussed are language production and the ability to understand sentences never heard before, sentence formation, children's construction of rules, children's language creativity, language acquisition and age,…

The purpose of this study was to investigate the linguistic differences in the spontaneous speech of language-deviant children in two very different situations. Spontaneous speech samples of eleven five-year-old language-deviant children were obtained from: (1) the traditional adult-child therapy situation using appropriate stimulus materials; and…

The Children's Language Assessment-Situational Tasks (CLA-ST) was developed to collect language samples within a normally operating classroom. The language is taken on a cassette tape recorder, which is placed at the foot of a small table. At this table, in a committee setting, four children are engaged with a teacher in an activity similar to…

In speaking a child sometimes makes constructions in which a sequence of separate utterances expresses a semantic relation not expressed by either utterance. These "vertical constructions" are the main point of this study. Previous studies of construction in child language have largely dealt with sentences. In this study, sentences are…
