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…

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…

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…

Four factors have been reported in the literature as being related to spatial test performance. This study investigated the main and interaction effects of sex, handedness, birth order, and experience on three different types of spatial performance; surface development, object rotation, and coordination of viewpoints. A total of 217 undergraduate…

Gender differences were examined on three computer-administered spatial processing tasks: (1) the Intercept task, requiring processing dynamic or moving figures; (2) the mental rotation test, employing rotated asymmetric polygons; and (3) the integrating details test, in which subjects performed a complex visual synthesis. Participants were about…

A study designed to investigate the relationship between spatial ability and selected social and emotional variables is presented. With the total sample of students in a freshman psychology course, and with the 48 females and 45 males separately, the relationship was investigated between spatial ability and participation in, and enjoyment of,…

Young children's responses to a velocity inference task based on static pictorial stimuli giving cues of proximity and ratio were examined. Subjects (N=65) in preschool through second grade viewed pictures of snails moving horizontally or spiders suspended vertically and were asked to estimate which competitor would reach its destination first.…

This study examined the construct validity of the Rod and Frame Test (RFT). Subjects were 554 clients (269 males and 285 females) (aged 14 to 65 years) of the Johnson O'Connor Research Foundation (JOCRF), a vocational guidance service. In a battery of diverse ability and style tests (19 tests of the JOCRF battery and 4 tests of cognitive style),…

Meta-analysis techniques were used to summarize the results concerning gender differences reported in doctoral dissertations on visual spatial skills. Dissertations were chosen because they are not subject to the selection process of journals, which may bias results toward large effects. An analysis of 150 independent data points in 43…

This study tested a causal model of the development of spatial visualization based on a synthesis of past and present research. During the summer and fall of 1999, 117 third- and fourth-year undergraduates majoring in architecture, mathematics, mathematics education, and mechanical engineering completed a spatial visualization test and a…

This investigation analyzed sex-related and age-related differences on spatial visualization tasks, reasoning tasks, and mathematical problem-solving tasks; and the effects instruction in visual thinking would have on these differences. Students in fifth grade, ninth grade, and in college, were tested before and after twelve weeks of instruction…

The effects of an experimental geometry course on gender differences in standardized test performance were studied. The experimental approach involved: (1) reading new concepts and materials followed by class discussion; (2) relating applications to real-life situations; and (3) conducting a spiraling review of concepts throughout the year.…

This paper presents the results of two studies which were performed to assess the effects of the practice of an interactive video game on spatial visualization test scores. The first study used 70 Laval University undergraduate students as subjects, while subjects for the second study were 101 seventh grade students from the area of Quebec City.…

As part of an ongoing study of sex differences in spatial ability, three preliminary hypotheses on parental socialization, sex role socialization, and biological explanations were tested, using 139 high school seniors as subjects. The early findings indicated that there was no support for the hypothesis that boys and girls differ in how they view…

Tests of spatial ability were analyzed for their analog (visuospatial) and nonanalog (verbal reasoning) components, using factor analyses of items and test scores. The self-selected sample consisted of over 2000 clients (average age about 26 or 27) employing the Johnson O'Connor Research Foundation's aptitude evaluation services in 12 metropolitan…
