The purpose of this study was to compare early speech and language development of children with and without cleft lip and/or palate (CLP) in the US and Slovakia from 6 to 24 months of age. Thirty-two children from the US (eight with CLP and eight noncleft) and Slovakia (eight with CLP and eight noncleft) participated in this study. The children…

A cross-sectional research study and a longitudinal research study failed to replicate previous research findings that indicated a linear relationship between age and mean length of utterance during the preschool years. Instead, a deceleration in age curves, particularly beyond about 36 months, was observed in each sample. (Author/CB)

To test D. Stampe's hypothesis about the development of phonological processes, 60 children (21 to 48 months old) were placed into groups based on mean length of utterance (MLU) and chronological age. MLU was found to be the best classification for describing the phonological processes. (Author/SEW)

Dialogue from 30-minute samples from "Sesame Street" and "Mr. Rogers' Neighborhood" was coded for grammar, content, and discourse. Grammatical analysis used the LINGQUEST computer-assisted language assessment program (Mordecai, Palen, and Palmer 1982). Content coding was based on categories developed by Rice (1984) and…

When lexical availability was manipulated through discourse support and word frequency for 40 target nouns, measurement of effects on length, complexity, order of mention, and fluency of 4- to 8-year-olds' utterances showed that the number and length of responses containing the target word varied with age, word frequency, and discourse support…

A 20-minute videotape sample was obtained of the language interactions between 20 Down syndrome children (ages 38 to 107 months) and their mothers during informal playtime. Linguistic utterances of mothers and children were coded according to the following language categories: query, declarative, imperative, performative, feedback, imitation,…

Maternal language directed to 21 nonhandicapped, 21 Down syndrome, and 19 language impaired preschool children was examined. The three groups (all Caucasian and middle-class) were matched in mean length of utterance (MLU) and in developmental skills as measured on the Vineland Adaptive Behavior Scale. Mother-child language interaction was…

This book is the second to present the results on a study of how children's practice of speech, as shaped by family interaction, affects learning to talk. Participating in the study were 42 diverse families with young children. Each month for 2.5 years the interactions between 42 one- to two-year-olds and their parents were recorded as the…
