Experimental studies demonstrate that contrast helps toddlers to extend the meanings of novel adjectives. This study explores whether antonym co-occurrence in spontaneous speech also has an effect on adjective use by the child. The authors studied adjective production in longitudinal speech samples from 16 children (16-36 months) acquiring eight…

This dissertation examines three processes affecting consonants in child speech: harmony (long-distance assimilation) involving major place features as in "coat" [kouk]; long-distance metathesis as in "cup" [p[wedge]k]; and initial consonant deletion as in "fish" [is]. These processes are unattested in adult phonology, leading to proposals for…

Semantic roles are a critical aspect of linguistic knowledge because they indicate the relations of the participants in an event to the main predicate. Experimental studies on children and adults show that both groups use associations between general semantic roles such as Agent and Theme, and grammatical positions such as Subject and Object, even…

There are numerous models of how speech segmentation may proceed in infants acquiring their first language. We present a framework for considering the relative merits and limitations of these various approaches. We then present a model of speech segmentation that aims to reveal important sources of information for speech segmentation, and to…

This study explores the form of representational gestures produced by forty-five hearing children (age range 2 ; 0-3 ; 1) asked to label pictures in words. Five pictures depicting objects and five pictures depicting actions which elicited more representational gestures were chosen for more detailed analysis. The range of gestures produced for each…

Purpose: During the evaluation of language abilities, the needs of the child are best served when multiple types and sources of data are included in the evaluation process. Current educational policies and practice guidelines further dictate the use of authentic assessment data to inform diagnosis and treatment planning. Language sampling and…

The present study investigates children's bias when interpreting novel noun-noun compounds (e.g. "kig donka") that refer to combinations of novel objects (kig and donka). More specifically, it investigates children's understanding of modifier-head relations of the compounds and their preference for HAS or LOCATED relations (e.g. a donka that HAS a…

In her very interesting Keynote Article, Johanne Paradis gives a clear overview of recent research at the interface of bilingual development and child language disorders, and highlights its theoretical and clinical implications. She raises the challenging question of "whether bilingualism can be viewed as a kind of "therapy" for SLI." At first…

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS…

I describe the results of an experiment that bears on how children learn the lexical and syntactic properties of abstract verbs ("seem," "try") in order to distinguish the subclasses of raising ("seem") and control verbs ("try"). Previous research suggested that an inanimate subject in certain contexts leads children to suppose that the subject…

Many languages distinguish generic utterances (e.g., "Tigers are ferocious") from non-generic utterances (e.g., "Those tigers are ferocious"). Two studies examined how generic language specially links properties and categories. We used a novel-word extension task to ask if 4- to 5-year-old children and adults distinguish…

This study explores different frequency effects on children's interpretations of novel noun-noun compounds (e.g. "egg bag" as "bag FOR eggs"). We investigated whether four- to five-year-olds and adults use their knowledge of related compounds and their modifier-head relations (e.g. "sandwich bag (FOR)" or "egg white (PART-OF)") when explaining the…

Children's production of bare nominals is universal. When acquiring languages disallowing bare nominals, children will develop from the bare to the non-bare stage. However, Mandarin nominals may appear bare or non-bare in various positions with all kinds of interpretations. This dissertation conducts two acquisition studies to examine the…

This study examined relationships between the spontaneous utterances of pre-kindergarteners (mean age = 5 years and 1 month) from low-income families during joint bookreading and their story retelling skills. Parent-child joint bookreading sessions (N = 62 dyads) and child story retelling sessions (N = 46) were videotaped. Results showed that…

In her interesting article, Stoel-Gammon (this issue) reviews studies concerning the interactions between lexical and phonological development. While the focus of the review is on vocabulary production from children acquiring American English, she also suggests that cross-linguistic research be undertaken to examine how universal and…
