Abstract: | Abstract— Recent research suggests that dynamic spatial reasoning tasks show more robust gender differences than static spatial reasoning tasks. These differences have implications for selection procedures based on aptitude test scores. Two experiments were therefore designed to examine the locus of such gender differences. In Experiment 1, 82 males and 82 females performed two separate tasks: judging the relative velocity of moving objects and judging their relative distances from target destinations. Significant gender differences occurred only for relative velocity judgments and were partially related to prior experience. A second experiment therefore tested the effects of practice and feedback on performance judging relative velocity. Male and female performance differences were again found, and performance improved equally as a result of feedback. Consistent with contemporary views of aptitude and assessment, the data suggest that equitable assessment of dynamic spatial abilities requires a determination of experiential history and learning rates as well as absolute performance levels. |
