The primary purpose of this study was to examine whether a general perceptual model developed by Vitz and Todd (1971), capable of dealing with multiple determinants of attending, is useful for understanding infant attending. The model, previously used in research with adults, assumes that perception can be represented as a stochastic sampling…

This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven…

This study investigated the process of perceptual exploration and organization of children as a function of age and sex in two experiments. In Experiment I, 3- to 5-year-old children named the pictures of nine familiar objects arranged in 3 x 3 matrices (exploration tasks) and indicated preference for objects represented in pairs (pair-completion…

Investigated 7-year-olds', 9-year-olds', and adults' ability to classify children's and adults' faces by sex using only biological based internal facial structure. Found that participants categorized adult faces by sex at accuracy levels varying from just above chance (7-year-olds) to nearly perfect (adults). All groups were less accurate for…

Recent studies have shown perceptual instability to be related to visual creativity as reflected in career choice. In general, those who display greater perceptual instability perceive themselves to be more creative and tend to choose careers related to visual creativity, regardless of their gender. To test the hypothesis that field independents…

The main purpose of this study was to investigate whether children's perceptual comprehension of symmetrical numerical displays was greater than their comprehension of asymmetrical numerical displays. Effects of sex, age and socioeconomic status were looked at. Seventy-three kindergarten and first grade children participated in the study.…

Spatial aptitude tests designed for elementary school children were given to third-grade students from both suburban and rural schools in Pennsylvania. Results were scrutinized by the declared favorite subjects of the participants and organized by gender. Students who preferred science and mathematics did better on spatial tests than students who…

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 report includes a description of the Frostig as a total instrument and an overall analysis, as well as separate analyses and descriptions of each subtest. A brief summary of the experimental design and sampling plan also is included. A summary of the AEL Early Childhood Program is available as PS 004 889. (Author/NH)

This study was designed to select and explore a research battery which, when administered at the beginning of the school year, more adequately predicts end of year reading achievement than have previously-used tests and test batteries. The tests used were perceptual-motor and cognitive-intellectual, with the most adequate predictor tests…

A class of preschoolers, aged 44-63 months and grouped according to age, sex, sibling position, family size and the occupation of each parent, were the subjects of a 2-part study to examine preschoolers' perceptions of mothers. In the first part of the study, each child was shown 4 sets of pictures depicting a variety of possible mother figures.…
