This study investigates whether developmental dyslexia involves an impairment in implicit phonological representations, as distinct from orthographic representations and metaphonological skills. A group of adults with dyslexia was matched with a group with no history of speech/language/literacy impairment. Tasks varied in the demands made on…

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall,…

The aim of this study was to compare the prosodic profiles of English- and Spanish-speaking children with Williams syndrome (WS), examining cross-linguistic differences. Two groups of children with WS, English and Spanish, of similar chronological and nonverbal mental age, were compared on performance in expressive and receptive prosodic tasks…

Recent studies of heritage speakers, many of whom possess incomplete knowledge of their family language, suggest that these speakers may be linguistically superior to second language (L2) learners only in phonology but not in morphosyntax. This study reexamines this claim by focusing on knowledge of clitic pronouns and word order in 24 L2 learners…

This study examined second language (L2) experience effects on children's acquisition of fluency-(speech rate, frequency, and duration of pausing) and prosody-based (stress timing, peak alignment) suprasegmentals. Twenty Korean children (age of arrival in the United States = 7-11 years, length of US residence = 1 vs. 11 years) and 20 age-matched…

Investigation of the use of five speech markers in the native and second-language production of French-English bilinguals (N=10) found no quantitative difference in the frequency of occurrence of speech markers between the high (N=5) and low (N=5) fluency speakers, although high-fluency speakers used more progressive than regressive marker types.…

When second, fourth, and sixth grade students were asked "What's this?" questions (differing in intonation and stress) and guessed whether there were new or different objects pictured on cards, results indicated that use of intonation was recognized as a marker for topic collaboration by grade four.
