Note. Participant type and target stereotypicality are effects-coded as STEM male (non-STEM female = −1, STEM female = 0, STEM male = 1), STEM female (non-STEM female = −1, STEM male = 0, STEM female = 1), and target (STEM-stereotypic = −1, feminine-stereotypic = 1). Coefficients are unstandardized. Hypothesized effects are bolded.
