Mental-rotation performance in middle and high-school age: influence of stimulus material,gender stereotype beliefs,and perceived ability of gendered activities

ABSTRACT

In psychometric mental-rotation tests, males mostly outperform females. The stimulus material and stereotype beliefs could partly be responsible for these differences. This was investigated in an experimental study administering traditional cube figures (C-MRT) and structurally similar pellet figures (P-MRT) to middle- and high-school aged children. 168 participants either solved the C-MRT or the P-MRT and filled out a questionnaire about their perceived ability of stereotypically masculine and feminine activities and about their gender stereotype beliefs. Overall, boys outperformed girls and all children who solved the C-MRT were better than those who solved the P-MRT. Only boys' mental-rotation performance increased with age while girls' perceived ability of stereotypically masculine activities decreased. A regression analysis identified children’s gender, their perceived ability of stereotypically masculine activities and their female gender stereotype beliefs as predictors of mental-rotation performance. Results are discussed with a focus on stereotype threat effects and gender differences in mental-rotation strategies.
