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.

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…

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.

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…

Explores (1) problems of the validity of tests of spatial ability, and (2) problems of the recessive gene influence theory of the origin of sex differences in spatial ability. Studies of cognitive strategies in spatial problem solving are suggested as a way to further investigate recessive gene influence. (Author/RH)

Sex differences in speed of solving mental rotation problems were replicated but college men and women were alike in frequency of use of algorithms to solve problems. The most frequent algorithm involved encoding stimuli in working memory, mental rotation of one to orientation of the other, comparison, and response. (Author/RD)

One hundred and seven 5th-8th graders were tested on spatial rotation multiple-choice items to determine age and gender differences in spatial ability. Thirty-one of them were subsequently interviewed. They were asked to explain their reasoning when solving 4 of the tested items and a problem-solving task. Features of visual and non-visual…

Two spatial visualization tests were administered to 142 students before and after two years of college study. Students majoring in the humanities and social sciences improved less than those majoring in mathematics and the physical sciences. Female physical science majors improved more than male physical science majors. (Author/RD)
