Investigated the relationship between sex hormones and spatial performance among adolescents treated with sex steroids for delayed puberty. Found that spatial performance varied according to gender but did not vary with levels of actively circulating sex steroids. Reviewed physiological mechanisms, developmental periods, and past empirical work…

Research on the emergence of sex differences in spatial ability during early adolescence prompted a meta-analysis of 172 spatial ability studies conducted since 1974. The meta-analysis confirmed that there are actually several spatial abilities, that some types of spatial ability show marked sex differences while others show none, and that spatial…

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.

Among the many theories attempting to explain sex differences in spatial ability, one of the most highly researched is the X-linked recessive gene theory. This is a review of the major research done on that theory and shows the conflicting nature of the results. (Author)

A total of 259 children between 5 and 12 years of age plotted the location and heading of an adult who was standing in their classroom onto a map of the classroom. Older children performed better than younger ones; boys performed better than girls. (MDM)

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…

Spatial cognition entails the ability to mentally represent spatial relations and to anticipate the course and outcome of transformations applied to those relations. The developmental histories of four tasks used to assess the maturity of spatial cognition in children are described. Significant effects were found for age, gender, task, and for…

Researchers disagree not only about the existence or magnitude of sex-related differences in spatial perception, but also about the determinants of such differences. Training in three distinct spatial tasks was provided in an attempt to destablize individual and sex-related differences, while exploring the relative contributions of biological and…

Four experiments examined sources of gender differences routinely found on the water-level spatial test. Undergraduates' errors offered no evidence that less accurate responses by females than males reflected a less developed Piagetian spatial system, and that females' requisite motor skills were poorer than those of males.

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)

Reports the results of cognitive test performance and early childhood activities in individuals with congenital adrenal hyperplasia, an autosomal recessive disorder associated with elevated prenatal adrenal androgen levels, demonstrating the effects of early exposure to excess androgenizing hormones on sexually dimorphic cognitive functioning.…

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…

This study was conducted to determine whether the filmic coding elements of split screen, slow motion, generated line cues, the zoom of a camera, and rotation could aid in the development of the Euclidean space concepts of horizontality and verticality, and to explore presence and development of spatial skills involving these two concepts in…

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…

The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
