Gender-, race-, and income-based stereotype threat: the effects of multiple stigmatized aspects of identity on math performance and working memory function

This study compared the relative impact of gender-, race-, and income-based stereotype threat and examined if individuals with multiple stigmatized aspects of identity experience a larger stereotype threat effect on math performance and working memory function than people with one stigmatized aspect of identity. Seventy-one college students of the stigmatized and privileged gender, race, and income-level completed math and working memory pre-tests. Then, participants heard a moderately explicit stereotype threat-inducing prime. Next, participants took math and working memory post-tests. Stereotype threat effects were found on math performance on the basis of race and income-level, but not on the basis of gender. Stereotype threat effects were found on working memory function on the basis of gender, race, and income-level. For both measures, the income-based effects were the strongest. Results also suggest the possibility of multiple minority stereotype threat effects on math performance and working memory. More specifically, individuals with three stigmatized aspects of identity experienced significantly larger stereotype threat effects than those with zero-, one-, or two-stigmatized aspects of identity.
