Examined whether variations in performance of (n=396) engineering students on a measure of spatial visualization were related to prior spatial experiences and to the developmental period when the prior experiences occurred. One finding revealed nonacademic activities seemed to have the most positive significant relationship to spatial…

Plomin and Foch's conclusion that sex differences in cognition account for very little of the total variability in test scores is challenged by demonstrating that on a complex test of spatial visualization the difference between males and females accounts for a quite substantial portion of variability.

Two psychometric tests measuring mental rotation (MR) and visualization (VZ) were administered to 209 male and 390 female high school seniors. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological, and practical consequences of these results are…

This quantitative study of imagery in 96 undergraduates addresses the problem of individual differences in the characteristics of mental imagery workspaces. A 20-item questionnaire embodying nine characteristics of mental imagery workspaces was administered to 78 females and 18 males. Analysis of variance by gender disclosed significant higher…

When adult versions of tests of spatial ability were modified and administered to 94 boys and 99 girls in Norway, results indicated that spatial ability is a more unified trait in boys than in girls, in whom spatial abilities are more heterogeneously organized. (SLD)

Research shows that young children are able to draw simple maps of their neighborhoods and to recognize features on aerial photographs. Among younger children there is little difference between the mapping ability of boys and girls, but as they grow older, boys consistently perform better in map drawing and map reading. (Author/SK)

Two processing abilities used to solve spatial problems are examined: (1) the analog ability of structural visualization; and (2) the non-analog ability of verbal analytic reasoning. The distinction is based on an evaluation of information processing theory and a review of process-oriented studies of individual differences. Criteria are presented…

This paper examines the differences between student performance on two separate measures, the Spatial Visualization portion of the "Differential Aptitude Test" and the "Geometry Content Knowledge Test." Results from the hybrid quantitative/qualitative study indicate that although there were no differences in performance on spatial visualization…

Investigated differences in performance between sexes on a spatial visualization task constructing pentaminos and whether supplying clues to the learner to guide would be a factor in performance. Concluded that males were more adept at identifying the shapes than females. (YP)

A study involving 477 female and 501 male fifth through eighth graders was conducted to investigate the differences in spatial visualization abilities and effects of instruction on spatial visualization skills of students by grade and sex. Instruction in visualization proved effective across grade and sex; retention of effects persisted after one…

Indicates that persons with different spatial visualization abilities enter different professions and that some sex differences exist with regard to spatial abilities. (RL)

Reports a study designed to investigate the effects of gender upon the acquisition of spatial and environmental skills among primary grade children. Results showed boys performed better on complex tasks and lend support to those who argue that more extensive movements of boys through the environment leads to superior spatial ability. (Author/JDH)

Describes a study that attempted to determine whether males and females differ in their ways of solving industrial arts psychomotor assembly tasks. Results support the theory that there is a realistic difference in the way males and females think when solving psychomotor tasks. (NRJ)

Because of the general recognition of the importance of mathematics ability, and the close relationship between mathematics ability and spatial ability, eight studies were undertaken to discover and describe aspects of spatial competence in children. The range of abilities tapped stretched from very early precursor skills with Euclidean space to…
