Summary
Men scored higher than women on visuospatial ability tests, including the new Judgment of Line Angle and Position-15 (JLAP-15) and Vandenberg Mental Rotation Test. Factors like strategy and math courses explained some, but not all, of the performance difference.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Educational Psychology
Background:
- Visuospatial ability is crucial for STEM fields.
- Existing tests like the Vandenberg Mental Rotation Test are widely used.
- Understanding sex differences in visuospatial skills is an ongoing research area.
Purpose of the Study:
- To introduce and evaluate the Judgment of Line Angle and Position-15 (JLAP-15) test.
- To examine the relationship between the JLAP-15 and the Vandenberg Mental Rotation Test.
- To investigate factors contributing to sex differences in visuospatial performance.
Main Methods:
- Administered the JLAP-15 and Vandenberg Mental Rotation Test to 86 men and 112 women undergraduates.
- Collected data on participants' strategies and number of prior mathematics courses.
- Utilized correlation and regression analyses to assess relationships and predictors.
Main Results:
- Men outperformed women on both visuospatial tests (d=1.04 for JLAP-15, d=1.10 for Vandenberg MRT).
- A significant positive correlation (r=.41) was found between the two tests.
- Strategy type, math courses, and sex predicted JLAP-15 performance, explaining 21% of the variance.
Conclusions:
- The JLAP-15 is a viable new measure of visuospatial ability.
- Sex differences in visuospatial ability persist, with strategy and academic background partially explaining performance.
- Further research is needed to fully understand the variance in visuospatial task performance.
