Stereotypes that women are less assertive and competitive than men lead women to experience stereotype threat in salary negotiations (Tellhed & Bjorklund, 2011), resulting in sex differences in salaries. The present experiment tested whether the effects of stereotype threat on negotiations are moderated by variables that may decrease the salience of sex such as dyad composition (same vs. mixed-sex), mode of communication (face-to-face vs. e-mail), and power. Ninety-six undergraduate participants (37 men, 59 women) negotiated for a hypothetical salary as well as an actual monetary award. As predicted, stereotype threat negatively affected women's outcomes and positively affected men's outcomes in mixed-sex pairs but not in same-sex pairs, Wald Chi-Square = 9.85, p= .002. Interestingly, there were no differences between the face-to-face and e-mail negotiations; both forms of negotiation were affected by stereotype threat in mixed-sex pairs. The basic findings of the present study were consistent with past research; participants assigned to a position of power were more successful in the negotiation regardless of their sex, Wald Chi-Square = 22.74, p < .001, d = 0.49. Limitations, implications, and possible ways to reduce the effects of stereotype threat are discussed. [ABSTRACT FROM AUTHOR]
