6. Do females hold more negative attitudes toward mathematics than males at an implicit level? Attitudes Toward Mathematics d = 1.03

7. Do females hold more negative attitudes toward science than males at an implicit level? Attitudes Toward Science d =.94

14. Primary findings Gender differences in orientations toward math measurable outside of conscious control Implicit findings were consistent with Heiders balance theory For females, gender identity related more strongly to implicit beliefs about mathematics For males, performance related more strongly with implicit beliefs about mathematics
