Examined 1 hour of conversation between 12 mothers and their 23-month-old children. Children were more likely to imitate correct grammatical morphemes after mothers' corrective recasting of children's errors than after three types of maternal responses that did not correct an error but did model a morpheme.

This article presents an overview of the literature on the cognitive hypothesis, which sees cognitive development as prerequisite to language development. It suggests that the cognitive hypothesis has had a significant influence on limiting eligibility of students with mental retardation for speech-language pathology services in schools.…

Examined how quality of center-based child care related to early cognitive and language development from 6 to 36 months among 89 African American children. Found that higher quality care was related to higher measures of cognitive, language, and communication development, even after adjusting for selected child and family characteristics.…

This study compared cognitive and linguistic development of young children with (N=28) and without (N=29) cleft palate. Children with cleft palate, although well within the normal range, performed significantly below the control group on cognitive and linguistic tests. Cognitive differences were linguistic in nature and were related to hearing…

Two experiments investigated how child and adult speakers of English and Kannada (Dravidian) interpret scopally ambiguous sentences containing numerally quantified noun phrases and negation. Results showed that 4-year-olds' interpretations were constrained by the surface hierarchical relations (the c-command relations) between sentence elements…

Used head-mounted eye-tracking system to study kindergartners' and adults' moment-by-moment language processing ability as they responded to spoken instructions. Found that 5-year-olds did not take into account relevant discourse/pragmatic principles when resolving temporary syntactic ambiguities and showed little/no ability to revise initial…

Examined how Japanese 2- and 4-year-olds assigned meaning to novel nouns associated with familiar and unfamiliar animals and inanimate objects. Found that in the absence of useful information from syntax, the 2-year-olds were able to fast map a noun to its meaning by elegantly coordinating word-learning biases and other available sources of…

Examined in six experiments toddlers' use of syntactic cues to learn proper names and count nouns. Found that by 24 months, both girls and boys were significantly more likely to select a labeled object if they had heard a proper name than if they had heard a count noun. At 20 months, neither girls nor boys demonstrated this effect. (Author/KB)

The development of the "inversion" effect in face processing was examined in infants 3 to 6 months of age by testing their integration of the internal and external features of upright and inverted faces using a variation of the "switch" visual habituation paradigm. When combined with previous findings showing that 7-month-olds use integrative…

The current study examined whether socioeconomic status (SES) and chaos in the home mediate the shared environmental variance associated with cognitive functioning simultaneously estimating genetic influences in a twin design. Verbal and nonverbal cognitive development were assessed at 3 and 4 years for identical and same-sex fraternal twin pairs…

The basic properties of a dynamic systems approach of development are illustrated by contrasting two simple equations. One equation is characteristic of dynamic systems models. The other refers to what, for the sake of simplicity, is referred to as the standard developmental approach. We give illustrations from cognitive, language and social…

The study investigated whether young children's health status is significantly related to their performance on measures of intelligence, language, and behavior, as well as parents' concerns, stress, and perceptions of their children's development. One hundred twelve 3 to 5 year-old children, recruited from a large pediatric practice and three…

"Theory of mind" development is now an important research field in deaf studies. Past research with the classic false belief task has consistently reported a delay in theory of mind development in deaf children born of hearing parents, while performance of second-generation deaf children is more problematic with some contradictory results. The…

The Executive Committee at "ZERO TO THREE" created a Task Force on Culture and Development to deepen our understanding of the role of culture in child development and to guide the organization through a self-assessment process to better understand how staff and board members address the issue of culture in their work. The task force's literature…

Derived from the first phase of a research study entitled "The Cognitive and Social Development of Pre-School Children in Singapore" (the IE-BvLF study), the essays in this collection focus on the language, numeracy, cognitive, and social development of approximately 3,000 Singapore children between 1983 and 1986. Following a prologue…
