This study investigated the development of perceptual, cognitive, and affective perspective taking in 167 kindergarten through sixth grade children. Task intercorrelations were low, nonsignificant, and inconsistent, supporting the view that perspective taking is a multidimensional social-cognitive construct. (JMB)

Individuals may be able to exert considerable control over their perceptual experience and environmental awareness by deliberately varying their "cognitive sets" - plans for selecting and processing information. This theme is explored and a research project, which included eleven experiments, on the effects of cognitive sets is reported. (BT)

Empirically describes the relative development of perceptual and conceptual understanding of left-right, back-front, up-down projective relationships between objects and provides a heuristic model of the cognitive processes involved in coordination of perspectives tasks. (Author/ED)

RECENT RESEARCH FINDINGS ON THE PERCEPTUAL DEVELOPMENT OF YOUNG INFANTS WERE SURVEYED, AND THE NEED FOR SYNTHESIZING THESE NEW FINDINGS INTO WORKABLE CONCEPTS WAS SUGGESTED FOR THE FRUITFUL STUDY OF HIGHER ORDER CONSIDERATIONS IN THE FUTURE. A DISCUSSION WAS MADE ON THE DEVELOPMENTAL ISSUES OF--(1) SUPERORDINATE CATEGORIES OF PERCEPTUAL FUNCTION,…

This study examined perceptual and articulatory confusions among the fricatives /f, v, s, z/ and voiced and unvoiced "th" in preschool children. (These phonemes are among the most difficult for children to articulate.) Seventeen children from 3.3-5.1 years of age were tested on syllables formed by taking all combinations of the six…

The relationship between children's perceptual, cognitive, and affective perspective-taking scores and their cognitive perspective-taking scores gathered one year later was assessed. Subjects were 56 kindergarten through third-grade children. (Author/JMB)

Tests the distinction between inferring new categories on the basis of property information (predicted to be difficult) and inferring new properties on the basis of category information (predicted to be easier) among 57 preschool children. (HOD)

Comparisons of age and test score correlations, comparisons of cross-sequential means, and trends of means for diagnostic subgroups and normal controls suggest developmental delay for all measured skills at all ages for autistic and schizophrenic children. Findings also suggest a trend for steady prepubertal cognitive skill development, followed…

Five developmental experiments examine the role of context in visual search. (Author/JH)

The development of multiplicative classificatory skills in children between 4 and 9 years of age was investigated by means of two forms of the matrix-completion task. (Authors)

Two experiments found that (1) by age 8 months infants perceived that leaning extends their effective reaching space to grasp objects; (2) by 10 months they perceived the effective limits of leaning and reaching; and (3) by 12 months they began to perceive how this space may be extended by a mechanical aid. (MDM)

Maintains that Madole and Oakes' hypotheses are incorrect. Shows that conceptual development frequently goes from the abstract to the concrete and that extensive literature shows that there is more than one kind of categorization. Discusses ways in which perceptual and conceptual categorization differ. (Author/KB)

Three experiments investigated whether 4-month-olds would attend to and utilize the global configuration ("good form") of a partly occluded, moving object to perceive its unit and coherence behind the occluder. Results indicated that curvature per se provided information in support of completion, in addition to global configuration and…

Examined the nature of numerical knowledge in 5-month-olds to inform the debate whether numerical abilities result from capacities dedicated to numerical cognition or to more general perceptual capacities. Found that 5-month-olds could determine the number of collective entities, moving groups of items, when non-numerical perceptual factors such…
