Examined the use by children of the Novel Name-Nameless Category principle, under the framework that lexical principles are acquired in a developmental sequence. Results indicated that the particular principle was not available at the start of lexical acquisition but that exhaustive categorization ability and a vocabulary spurt occur…

A 7-month longitudinal study of 20 2- and 3-year-old children shows that children at an early age already know that counting words each refer to a distinct numerosity, although they do not know to which numerosity. It takes children a long time to learn the latter. (SLD)

Reviews the research on (1) developmental stages of play among young children; (2) solitary play as a separate continuum with its own developmental stages; and (3) benefits of solitary play on the child's whole development. (BB)

Evaluation of the Kent Scoring Adaptation, which determines developmental ages in several domains based on an infant's performance on the Bayley Scales of Infant Development, with 27 at-risk infants supported the concurrent validity of the cognitive, language, and, to a degree, social domains of the Kent procedure but not the fine and gross motor…

Studied the relationship of family background and child care quality to preschoolers' cognitive, language, and social development. Concluded that family background variables were significant predictors of children's cognitive and language development, and that child care quality variables significantly predicted social adjustment and were a…

Used a cross-sectional natural language database to investigate the parent-child conversations of 3-, 4-, and 5-year olds. Found that 4-year-olds and, to a greater extent, 5-year olds reliably used explicit contrastives. All the children regularly elicited mentalistic responses from their parents and, in some cases, these parental responses were…

Summarizes research findings that challenge long-standing theories of infant cognition and motor development and proposes alternative theoretical models to describe skill acquisition during the first several years of life. Findings are discussed with respect to research in the area of infant speech physiology and production. (Author/CR)

Examined ability of Quebec French-speaking first graders to categorize words on the basis of vowel categories. Found that ability to categorize vowels does not develop uniformly but is affected by degree of spectral/articulatory proximity between vowels, by syllable structure, and potentially by characteristics of the input phonology. (JPB)

Examined whether 2-year-olds can learn a novel part name of an unfamiliar object when adult demonstrates action upon object. Asked 24 Japanese 2-year-olds to choose referent for a whole object and part of the object in forced choice tests. Found that young children are able to override whole object assumption when actions of parts of objects are…

Adult and child L2 acquisition of syntax-semantics interface phenomena must be compared with monolingual L1 acquisition of the same phenomena in order to assess the possible effects of interference and transfer. However, this "L1A touchstone" can also be misleading because non-grammatical mechanisms that interact with such interface phenomena may…

Interest in U-shaped development has itself undergone a U-shaped progression. Twenty-five years ago, interest in U-shaped development was high. This interest was evident at a 1978 conference in Tel Aviv on "U-shaped Behavioral Growth" that resulted in the publication of a book of the same title 4 years later (Strauss, 1982). The breadth…

For infants and toddlers, education and care are "two sides of the same coin." The author briefly reviews current research on the importance of relationships to cognitive development and early language and literacy. Instructional strategies that are most appropriate to the early years include "intentionality" and "scaffolding." Intentionality…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

In the current research project, the relationship between neighborhood environment and school readiness was investigated. To measure neighbourhood environment, data from the 2001 Canadian Census were used, while school readiness was measured using the Early Development Instrument (EDI). EDI data were collected for kindergarten children across…

This theme issue discusses family literacy in six articles, covering: (1) visions of family literacy from research and practice; (2) a family-to-family tutoring model (Susan Weinbeck); (3) a strengths learning model (Meta W. Potts); (4) the LVA/GTE (Literary Volunteers of America/General Telephone and Electronics Corporation) family literacy…
