If a child asks a friend to play football and the friend replies, 'I have a cough', the requesting child must make a 'relevance inference' to determine the communicative intent. Relevance inferencing is a key component of pragmatics, that is, the ability to integrate social context into language interpretation and use. We tested which cognitive…

This volume presents the findings of a large-scale study of individual differences in spoken (and heard) language development during the school years. The goal of the study was to investigate the degree to which language abilities at school entry were stable over time and influential in the child's overall success in important aspects of…

To examine the persistence of phonological selectional constraints on young children's lexical choices, the words attempted in the conversational speech of a longitudinal sample of 12 normally developing preschoolers from age 2;0 to 5;0 were scored for syllabic length, presence of consonant clusters, and distribution of constituent phonemes. (29…

A study examined the consistency of consonant use in the infant's transition period from babbling to early words. Phonetic data were collected from the speech of 10 infants aged 9 to 15 months. Analysis of consonant distribution patterns indicate striking segmental preferences in all 10 children, with some segments more prominent for the sample as…

A validation study of five checklists for assessing two-year-olds' word production revealed that the lists produced comparable mean production scores, reflected age differences, and preserved individual differences in total production and in production of linguistic categories such as nouns, verbs, open class items, and closed class items.…

Research on child language acquisition should distinguish between different possible causes of variation and not just attribute variation to individual variation. An alternative analysis using a different methodology can show that children's patterns of acquisition are actually relatively similar. (Author/CB)

The purpose of this study was to determine whether individual differences observed in the grammatical morphology of children with specific language impairment (SLI) could be traced to another source, such as the use of weak syllables. Results show that imitations in prosody may restrict the degree of grammatical morpheme use by children with SLI.…

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…

Prepared as part of a British project investigating children's language at home and at school, the study described in this paper centered on an examination of the spoken and written narrative texts produced by children to determine (1) the relationship between spoken and written texts; (2) the differences, if any, in the production processes used…
