Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency,…

Research on sources of individual difference in parental Infant-Directed Speech (IDS) is limited and there is a particular lack of research on fathers' compared to mothers' speech. This study examined the predictive relations between infant characteristics and variability in paternal lexical diversity (LD) in dyadic free play with two-year-olds (M…

Nineteen shy, twenty-three middle and twenty-five non-shy junior kindergarten children were assessed at school by an unfamiliar examiner, and at home where their parents administered a parallel form of the expressive and receptive vocabulary tests given at school. A speech sample between the child and parent was also collected at home. Shy…

Investigated whether crosslinguistic interference occurs in the domain of subject realization in Spanish in a bilingual (Spanish-English) acquisition context.

A methodological study of 33 2-year-olds shows that child speech occurs at about the same level in different settings (the familiar home vs. the unfamiliar laboratory), but that children speak more and in more differentiated ways with different people (mother vs. stranger). (Author/VWL)

Examined developmental stability and change in children's private speech during the preschool years across-task constituency in children's self-speech, and across-setting relations between private speech in the laboratory and behavior at home and in the classroom. Clear associations were found between children's private speech use in the…

Examines mealtimes of preschoolers' families to determine whether rare words are used in informative ways so that a child could learn their meanings. Each use was coded for whether it was informative or uninformative; each informative exchange was coded for type of strategy used to provide support. Frequency of use was positively correlated with…
