Performance factors and gender-related differences in spatial ability: another assessment.
To explore whether test-taking styles (performance factors) can contribute to explaining gender-related differences on tests of spatial ability, 15 spatial tests were administered to three samples of subjects. On each test, number-correct scores and ratio scores (number of items solved divided by the number of items attempted) were computed. In accordance with previous research findings, the use of ratio scores significantly reduced the magnitude of the gender-related differences on the Mental Rotations Test. For most of the remaining tests, however, the reduction of the gender-related score difference was small. It was concluded that the difference reduction for the Mental Rotations Test was specific to the format of this test. In common spatial tests, performance factors may account for a small portion of gender-related variance, but the bulk of this variance must be attributed to other factors.
