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…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

In this paper we consider a collection of conversational practices that arise when a professional is faced with extended resistance to their offered advice. Our data is comprised of telephone calls to a UK child protection helpline. The practices we identify occur repeatedly across our corpus of advice resistance sequences and involve (1) the…

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…

In order to determine how well persons can learn to recognize vibratory speech patterns, six normally-hearing adults felt speech presented to their fingertips through vibrators. (Author)

Background: High levels of behaviour problems are found in children with language impairments, but less is known about the level and nature of language impairment in children with severe behavioural problems. In particular, previous data suggest that at primary age, receptive impairments are more closely related to behaviour problems, whereas…

Attempts to demonstrate that a complete description of elliptical coordinations can be obtained only if the uses of elliptical and nonelliptical coordinations are investigated also. Future research on elliptical coordinations should be directed towards more full-scale analyses of the genres discussed here and other genres. (31 references) (CK)

When vocalizations of three-month-olds (N=40), experiencing either conversational turn-taking or random responsiveness of an adult, were counted and categorized, results indicated that turn-taking caused changes in the quality of vocal sounds. When the adult maintained a give-and-take pattern, the infants produced a higher ratio of…

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.…
