Purpose: The purpose of this study is to compare the outcomes of the manually coded Northwestern Narrative Language Analysis (NNLA) system, which was developed for characterizing agrammatic production patterns, and the automated Computerized Language Analysis (CLAN) system, which has recently been adopted to analyze speech samples of individuals…

This study examined the relationship between targeted pronunciation instruction in French as a second language (L2) and listener-based ratings of accent, comprehensibility, and fluency. The ratings by 20 French listeners evaluating the speech of 30 adult L2 French learners enrolled in a 15-week listening and speaking course targeting segments,…

When children hear a novel word in a context presenting a novel object and a familiar one, they usually assume that the novel word refers to the novel object. In a series of experiments, we tested whether this behavior would be found when 2-year-olds interpreted novel words that differed phonologically from familiar words in only 1 sound, either a…

This study described the commenting practices of Head Start teachers, and the relationship of comments to the expressive and receptive vocabulary growth of children with below-the-mean language ability across one year of preschool. Participants included 52 Head Start teachers, and 489 children (247 early intervention candidates and 242 Head Start…

The roles of linguistic, cognitive, and social-pragmatic processes in word learning are well established. If statistical mechanisms also contribute to word learning, they must interact with these processes; however, there exists little evidence for such mechanistic synergy. Adults use co-occurrence statistics to encode speech-object pairings with…

Previous work leaves open the question of whether children with autism spectrum disorders aged 6-12?years have delay in producing gestures compared to their typically developing peers. This study examined gestural production among school-aged children in a naturalistic context and how their gestures are semantically related to the accompanying…

A long history of research has considered the role of iconicity in language and the existence and role of nonarbitrary properties in language and the use of language. Previous studies with Japanese-speaking children, whose language defines a large grammatical class of words with clear sound symbolism, suggest that iconicity properties in Japanese…

Experience-dependent enhancement of neural encoding of pitch in the auditory brainstem has been observed for only specific portions of native pitch contours exhibiting high rates of pitch acceleration, irrespective of speech or nonspeech contexts. This experiment allows us to determine whether this language-dependent advantage transfers to…

The term "phrase-level reduction" refers to transformations of the phonetic forms of words in connected speech. They are a characteristic property of fluent speech in normal speakers. Phrase-level reductions contribute to a reduction of articulatory-motor effort and constitute an important aspect of speech naturalness. So far, these phenomena have…

Two children's conversations with adults were examined for reference to moral issues using transcripts of archived at-home family talk from the Child Language Data Exchange System (CHILDES) database (MacWhinney, 2000). Through target words (e.g., good, wrong, mean) in transcripts of two children between ages 2.5 and 5.0 years, 1,333 moral…
