There has been limited research on identifying and understanding co-occurring challenges associated with Developmental Language Disorder (DLD). This is an exploratory study to examine the sensory profile of school-age children with DLD, and to investigate possible relationships between sensory profiles and language skills. Chart information was…

In 3 studies (N = 188) we tested the hypothesis that children use a perceptual access approach to reason about mental states before they understand beliefs. The perceptual access hypothesis predicts a U-shaped developmental pattern of performance in true belief tasks, in which 3-year-olds who reason about reality should succeed, 4- to 5-year-olds…

Describes two experiments that assessed young children's understanding of the characteristic uncertainty in the physical nature of random phenomena as well as the unpredictability of outcomes. (HOD)

Responds to four commentaries on the article by Jones and Smith in this issue. Suggests that the comments derive from the possibility that stable concepts might not exist and from the difficulty of imagining what cognition could be without represented concepts. Discusses traditional approaches to stability and variability, and considers what…

This paper reviews studies which describe the nature and extent of children's association of white with good and black with bad. As children become older, their perceptions of the colors white and black become differentiated from their perceptions of White and Black people. (Author/RD)

Four- and seven-year olds were asked to make and explain predictions about their abilities to solve perceptual problems, perform the tasks, and explain their success or failure. Results indicated that young children have some clear-cut knowledge, and misconceptions, about their senses. Between four and seven years, children become increasingly…

Reviews current research on children's concepts and categories that reflects a growing consensus that nonperceptual knowledge is central to concepts and determines category membership, whereas perceptual knowledge is peripheral in concepts and only a rough guide to category membership. Argues that there is no compelling basis in theory or in data…

Comments on the article by Jones and Smith in this issue. Responds to the theses that perceptual information is as much at the core of concepts as is nonperceptual information and that concepts are not represented as such but are computed on-line when needed. Presents a view of the relationship between perception and conceptual knowledge…

Comments on the article by Jones and Smith in this issue. Describes a program of research that demonstrates the important influence of perception on the structure of concepts. Proposes that both perceptual and nonperceptual information are important to conceptual structure throughout the continuum of knowledge acquisition and that perception is a…

Comments on the article by Jones and Smith in this issue. Outlines different perspectives from which the issue of conceptual development is approached, elaborating on the functions concepts serve and variations in those functions. Notes points of agreement with the perceptual knowledge view and offers comments on the research supporting the…

This commentary on the article by Jones and Smith in this issue examines whether coherent conceptual cores exist in long-term memory; abstract propositions constitute conceptual cores; concepts in long-term memory control behavior; and the primary purpose of developing and using concepts is to taxonomize the environment. (TJQ)

Contends that young children show surprising awareness of other's feelings. Provides background research concerning children's understanding; addresses levels of understanding of perception, emotions, desires, and beliefs; advises how parents and teachers can support children's development of understanding; and notes the powerful role and…

Five and seven year olds were able to correctly distinguish between factual and fictional television programs and test clips, based upon genre of program, production features, content. Age and vocabulary scores predicted accuracy of factuality judgments, but television viewing history did not. Older children understood better than younger ones…

UNDER THE DIRECTION OF PROFESSOR BRUNER, THE CENTER FOR COGNITIVE STUDIES AT HARVARD UNIVERSITY HAS CARRIED OUT A SERIES OF STUDIES ON THE DEVELOPMENT OF COGNITION. THERE HAVE BEEN OVER 30 EXPERIMENTS ON THE GROWTH OF PERCEPTION, PROBLEM-SOLVING, AND REASONING BETWEEN THE AGES OF 3 AND 10, IN PURSUIT OF A THEORY TO ACCOUNT FOR THE CHANGES IN…
