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)

The association of locus of cerebral hemispheric specialization of spatial function with identity and equivalence conservation judgments was tested in a group of four- to six-year-old right-handed children (N=31). (Author/MP)

Used a multivariate approach and longitudinal design to examine the relationship of early perceptual and cognitive development in first grade, to school achievement in fourth grade. Results indicated variables used to predict achievement differed between the sexes, and sex as a predictor variable depended upon area of achievement studying.…

A total of 416 elementary school children described in writing what their grandparents meant to them. Girls were more likely than boys to mention love. Younger children reported obtaining more affective provisions (e.g., attachment and nurturance) from grandparents while older children reported more cognitive provisions (e.g., guidance and pride…

Reports a study investigating the relationship between cognitive styles and the preschool child's use of play areas in nursery schools, using daily observation and two tests of analytic perceptual ability. (ED)

Results argue against the too frequent use of human figure drawings as a single, stable, and accurate measure of intellectual ability. (Authors/CB)

This study was undertaken to determine the relative contribution of age, sex, and three stimulus features (board shape, block arrangement, and block shape) to perceptual accuracy on 39 board/block adaptations of Piaget's three-mountain task. (Author/SB)

Investigated secondary-level students' (N=66) understanding of three-dimensional structures in biology. Results suggest that student performance is highly correlated with age, scientific ability, and sex. Suggestions for instructional improvement in spatial relationships are offered. (ML)

Two techniques were used to modify an impulsive conceptual tempo on a visual discrimination task. The subjects were 42 first grade white children who had previously been classified as impulsive or near-impulsive on the Matching Familiar Figures Test given to 82 children. These subjects, who had scored above the median on errors and below the…

This study examines the relationship between mother-infant behavior and the infant's performance on perceptual-cognitive tasks as a function of the infant's sex. A total of 189 12-week-old infants and their mothers were observed in their homes during 2 hours of infant awake time. In addition, the Mental Development Index (MDI) of the Bayley Scales…

Investigates the TacVi Technique as a tactile and visual method of exploring 37 Mexican-American preschool children's perceptions of themselves in comparison with their peers. (HOD)

The development of perceptual, cognitive, and affective perspective taking and empathy was investigated in 96 kindergarten through third-grade children. Cognitive perspective taking was found to increase between second and third grades. Affective perspective taking, in situations controlling for the likelihood of the subjects' projecting their own…

The purpose of this study is to show that there is a gradual and measurable development in the drawing of space representation concepts. A further purpose is to show that children's drawings of a village (which represent relations among concepts) may be a better measure of their conceptual maturity than their drawings of a man (which represent a…

Sex differences in cerebral organization and functioning, and the apparent superiority of males in spatial ability are examined in this paper. Attention is given to several kinds of cognitive and perceptual tasks in which sex differences in spatial ability have been shown to exist; among these are tasks involving: (1) recall and detection of…

This paper describes the purposes and procedures of a longitudinal study designed to: (1) relate mother-infant interaction patterns to infant age, sex, and social class; (2) relate mother-infant interaction patterns to infant sensory-motor development; and (3) to examine the relationship between infant sensory-motor development and infant sex and…
