On average, men tend to outperform women on tests of spatial ability; I am interested in using a biopsychosocial model in order to research why this occurs. I am currently investigating gender differences in performance on tests of mental rotation and the effect of various item types and test instructions on the magnitude of these gender differences. I am also examining the impact of stereotype threat on gender differences in math and spatial performance.

a) A mirror occluded item from the MRT-B2. Alternatives one and two are correct, whereas alternatives three and four are mirror images of the target item (distractors); the fourth alternative is occluded. b) An analogous mirror occluded item from the MRT-R2. Alternatives one and two are correct, whereas alternatives three and four are mirror images of the target item (distractors); the fourth alternative is occluded.
