In spoken languages, children acquire locative terms in a cross-linguistically stable order. Terms similar in meaning to in and on emerge earlier than those similar to "front" and "behind," followed by "left" and "right." This order has been attributed to the complexity of the relations expressed by…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

This study focuses on the relationship between content elements and mental-state language in narratives from twenty-seven children with autism (ASD), twelve children with language impairment (LI), and thirty typically developing children (TD). The groups did not differ on chronological age (10;6-14;0) and non-verbal cognitive skills, and the…

Several cognitive accounts of human communication argue for a language-independent, prelinguistic basis of human communication and language. The current study provides evidence for the universality of a prelinguistic gestural basis for human communication. We used a standardized, semi-natural elicitation procedure in seven very different cultures…

Parent-child conversations are a potential source of children's developing understanding of the biological domain. We investigated patterns in parent-child conversations that may inform children about biological domain boundaries. At a marine science center exhibit, we compared parent-child talk about typical sea animals with faces (fish) with…

Examines mothers' and fathers' speech for similarities and differences as expressed in four categories of messages to their preschool daughters and sons: plans, strategies, symbolic play utterances, and extrasituational references. (MP)

This study investigates features of interaction between children that are linked to the development of understanding of mind, and asks whether these associations are evident across different relationships. Comparisons are made of the naturally occurring conversations in a sample of 43 4-year-old children, each observed with a sibling and with a…

Two experiments tracked infants' eye movements to examine use of word-initial information to understand fluent speech. Results indicated that 21- and 18-month-olds recognized partial words as quickly and reliably as whole words. Infants' productive vocabulary and reaction time were related to word recognition accuracy. Results show that…

Examines the ability of young and older adults with mild to moderate mental retardation to produce complex sentences in naturalistic conversation. The complex sentences produced were coded into subcategories of complementation, relativization, or coordination and then analyzed. No significant differences were observed between the two age groups.…

Examines the use of reference by kindergartners and second graders in told, dictated, and written texts. Explains findings in terms of increasing precision in the use of anaphoric and situational reference by mode. (HOD)

Examined whether the quality and content of everyday parent-child conversations about negative emotions differed from everyday talk about positive emotions. Found that children and parents talked about past emotions, causes of emotions, and connections between emotions and other mental states at higher rates during conversations about negative…

This study examines the hypothesis that the lack of parental approval of the child characterizes child-abusing families. As part of a larger study of the coping styles of such families, a variety of verbal and non-verbal behaviors in parent-child interactions was examined. Subjects were 80 mother-child pairs from among four groups of comparable…

A study relating mothers' language styles and techniques of family control to children's cognitive development was conducted with 163 urban Negro mothers from the lower and middle classes and their 4-year-old children. The following conclusions were drawn: (1) There was a significant negative correlation between responses of status-oriented…
