Classroom discourse is evaluated for the contribution it can make to students' learning in groups. Data recorded from primary age children working at computers are categorized as exploratory, cumulative, and disputational talk. The teacher's role in making explicit strategies that optimize exploratory talk is discussed. (Contains 31 references.)…

To study lexical knowledge relevant for school success, 40 monolingual Dutch and 40 bilingual Turkish 9 and 11-year olds were asked to explain the meanings of common Dutch nouns in an extended word definition task. Compared to the monolingual Dutch children, the bilingual Turkish children allotted less extensive and varied meanings to Dutch words.…

Investigated the relationship between children's failures to produce unambiguous utterances and the mental effort demands in children (ages five, six, seven, and nine years), using finger-tapping and message production tasks, separately and simultaneously. Findings suggest that the relative effort requirements of communication decrease with…

Sampled the speech of American, French, and Swedish mothers to their one-year olds, to analyze distribution of phonetic parameters of adult speech, as well as children's own early words. Found that variability is greater in child words than in adult speech, and mother-child dyads showed no evidence of specific maternal influence on phonetics of…

Examines children's variation in rate, style, and sequence of grammatical development, within and across natural languages. Using a sample of English and Italian infants, concludes that while there are structural differences between English and Italian that could affect the order in which nouns and verbs are acquired, no differences were observed…

In a study of differences in frequency of interruptions, aspects of dominant-submissive sex role behavior in preschool children and their teachers during conversation were examined. Boys interrupted teachers more than girls did, and teachers interrupted girls more than they did boys. (LB)

Cultural stereotypes that interpret girls as less forceful or less assertive than boys in pursuing their own agendas, particularly during conflict episodes, are questioned. A theory of double-voice discourse is proposed to characterize a type of conflict talk that has a dual orientation, and examples for three- and four-year-old girls' talk are…

This article on sampling early semantic productions reports a study of 6 children (ages 31-35 months) with specific language impairments. Subjects produced a greater frequency and diversity of multiword utterances in a free-play sampling situation than in a joint action routine sampling situation. (JDD)

Two sets of meta-analyses examined gender effects on parents' observed language with their children. Findings indicated that mothers talked more, used more supportive and negative speech, and less directive and informing speech than fathers. Mothers talked more and used more supportive speech with daughters than sons. Effect sizes depended on…

Describes the phoneme repertoires and phonological error patterns used by Cantonese-speaking children, as well as a longitudinal study of tone acquisition by four children. The developmental error patterns used by more than 10% of children are reported as common in other languages. Specific rules associated with Cantonese phonology are identified.…

Investigates children's early lexical development in English and Korean and compares caregivers' linguistic input in the two languages. Results indicate that young Korean children use verbs productively with appropriate inflections and that, unlike in English, both verbs and nouns in Korean are dominant categories from the single-word stage. (39…

Examined language differentiation in bilingual toddlers prior to the emergence of functional categories. The children were observed with each parent separately and both together. Results indicate that while these children did code mix, they were able to differentiate between their two languages. There was some evidence that language dominance…

The authors' objective in this article was to explore the accuracy of mothers' estimates concerning their children's developmental functioning, especially with respect to vocabulary and gross motor development, by comparing the results of diagnostic tests administered to both the children and their mothers. The authors studied 55 children with…

This study examines the production of regular and irregular participle forms of German with high and low frequencies using a speeded production task. 40 children in two age groups (five- to seven-year olds, eleven- to twelve-year olds) and 35 adult native speakers of German listened to stem forms of verbs presented in a sentential context and were…

Research undertaken to date suggests that important developments in the understanding and use of intonation may take place after the age of 5;0. The present study aims to provide a more comprehensive account of these developments. A specially designed battery of prosodic tasks was administered to four groups of thirty children, from London (U.K.),…
