In learning language, children must discover how to interpret the linguistic significance of phonetic variation. On some accounts, receptive phonology is grounded in perceptual learning of phonetic categories from phonetic distributions drawn over the infant's sample of speech. On other accounts, receptive phonology is instead based on phonetic…

This study characterized early language abilities in toddlers with autism spectrum disorders (n = 257) using multiple measures of language development, compared to toddlers with non-spectrum developmental delay (DD, n = 69). Findings indicated moderate to high degrees of agreement among three assessment measures (one parent report and two direct…

This study explored the sensitivity of 20 10- to 11-month-old infants to the phonological characteristics of their native language. Tone-probe event-related potentials were obtained for subjects listening to a story, either with normal English function morphemes or modified with atypical function morphemes. Results suggest that the 11-month-olds,…

Purpose: This study tests the hypothesis that toddlers with autism spectrum disorders (ASD) will show differences from contrast groups in preferences for attending to speech. Method: This study examined auditory preferences in toddlers with ASD and matched groups of (a) typical age-mates, (b) age-mates with nonautistic developmental disabilities,…

Purpose: Language and speech are difficult to assess in newly arrived internationally adopted children. The purpose of this study was to determine if assessments completed when toddlers were first adopted could predict language outcomes at age 2. Local norms were used to develop early intervention guidelines that were evaluated against age 2…

Analysis of characteristics of 53 children with specific language impairment (SLI), ages 4 to 9, suggested that family history is related to pattern of language performance. Children with deficits in only expressive language had a higher proportion of affected family members than did children with both expressive and receptive language deficits.…

Evidence for speaker knowledge of morphological patterns, both derivational and inflectional, is not limited to productive patterns. Nonproductive patterns appear to be accessible in such a way that accessibility (a term preferred to "psychological reality") may be viewed as a function of four somewhat interdependent factors: (1) productivity, (2)…

Developmental trends in the effects of expectations regarding agent/action matches on judgments of sentence acceptability were investigated. Five sentences reflected expected relations ("harmonious") and five contradicted them ("contrary"). Twelve subjects each were in grades 4 through 8 during year 1; the same 60 subjects…

This bibliography contains references to materials relating to language learning and development in the young child, specifically, speaking and understanding language. Receptive, communicative and expressive language as well as particular facets of language imitation and production are topics included. Reference materials are listed in four major…

This booklet offers practical, easy-to-read suggestions for teachers, paraprofessionals, and parents to help them understand language development and language disabilities. The first section highlights some of the factors involved in language development. The second section deals with some of the common causes for language disabilities and…

This study investigated the relationship between dialect usage and performance on four language tasks designed to reflect features developmental in nature: articulation, grammatical closure, auditory discrimination, and sentence comprehension. Predictor and criterion language tasks were administered to 90 kindergarten, first-, and second-grade…
