Examined individual growth rates in definitional skill over a period of 3 to 6 years, for 68 low-income children. Results of the study support the notion that definitional skill is related to being part of an academic culture; low-income mothers, whose formal schooling is complete, generally do not give oral definitions to simple nouns as well as…

This paper explores "fast mapping", one of several processes that have been proposed to be involved in the rapid vocabulary expansion observed in the preschool years. An adaptation of a receptive word matching task examined how well children retained a just-mapped relation between word and referent when some information was later missing.…

Examined children's generalization of familiar verbs to novel events. Findings reveal children aged 1;8 with the largest expressive vocabulary generalized the same verbs to actions with different agents, but not to actions different in outcome or manner of action and children aged 2;2 extended familiar action verbs to other actions different in…

Examined miscommunication episodes occurring between 2.5-year-olds and their parents during videotaped free play sessions. Although children generally responded appropriately in form to parental clarification requests, they responded more often to and resolved successfully more of those following their own requests than those following their…

Compares the prosodic modifications in mothers' and fathers' speech to preverbal infants in American and British English, French, German, Japanese, and Italian. Speech samples were instrumentally analyzed to measure mean fundamental frequency, variability, utterance, duration, and pause duration. (67 references) (Author/CB)

Reports on longitudinal data from a group of three- to six-year-olds (N=64) that supports a hypothesis that acquaintance with nursery rhymes positively affects children's reading ability. Data showed a strong relation between early knowledge of nursery rhymes and success in reading and spelling, despite differences in social background,…

Normal and Specific Language Impaired (SLI) children were tested for evidence of the binding domain and orientation properties of their grammars. Results suggest that normal children acquiring English pass through a long-distance binding stage, whereas SLI children behave like very young normal children in requiring the nearest available noun…

Focuses on the influence of language specific properties in the acquisition of locative expressions. Some of the claims from literature on the acquisition of locative expressions are discussed and data from the acquisition of Warlpiri are presented and discussed in terms of these claims.

Analysis of data from studies investigating the effectiveness of a parent report form for assessing children's early language development showed that the vocabulary checklist had substantial validity, and that it helped parents to provide a valuable overall evaluation of their children's language at 20 months. (Author/CB)

Data from two-year-old children and mothers were collected concerning age at which she began to read to child, frequency of home reading, number of stories read per week, frequency of visits by child to library. Picture-book reading exposure was more strongly related to receptive than expressive language. Age of onset of home reading routines was…

Analysis of the babbling of five infants indicated that between 14 and 40 percent of utterances recurred in particular contexts with a greater than expected frequency, suggesting that babbling is not entirely random but contains consistent sound-meaning relationships that are not adult-modeled. (Author/CB)

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)

Comparison of maternal speech to three-month-olds between American (N=20) and Japanese (N=20) mother-infant dyads revealed that infant gaze affected the intended functions of maternal speech differently for the two groups. Cultural differences were also seen in the nature of function-form and function-referent relationships. (Author/CB)

Cross-cultural investigation of the influence of target-language in infant babbling analyzed 1047 vowels produced by 10-month-olds (N=20) from French, English, Cantonese, and Arabic language backgrounds. Results revealed differences among infants across language backgrounds, with the differences paralleling those found in adult speech in the…

The order in which wh-questions are acquired in the production and comprehension of two Korean one-year-olds is analyzed and compared. Consistencies in acquisition order are to be based on universals of cognitive development, while discrepancies in acquisition order were attributed to differences in interactive styles across caregivers and…
