A regulatory fit occurs when an outcome is presented in gain frames under a promotion focus and in loss frames under a prevention focus. Combining research on regulatory focus and research on stereotype threat it is argued that regulatory fit may result from stereotype threat (loss frame) under a prevention focus and from the absence of stereotype threat (gain frame) under a promotion focus. In line with previous research it is proposed that regulatory fit a) enhances motivation (Studies 1 and 2) and b) creates a feeling right experience that increases the persuasiveness of external stimuli (Study 3). In all three experiments regulatory fit was operationalized as experiencing stereotype threat when under a prevention focus or, respectively, experiencing the absence of stereotype threat when under a promotion focus. Further, women's aspirations to engage in a leadership role were assessed. In Studies 1 and 2 it was shown that women's motivation to occupy a leadership role was enhanced in the regulatory fit conditions compared to women in the nonfit conditions. Study 3 demonstrated that a stimulus (i.e., role model) was more persuasive under regulatory fit. Women experiencing regulatory fit compared to women in the nonfit conditions were more persuaded by role models, showing more interest in a leadership role when confronted with a positive model and less interest when confronted with a negative model. These studies show that stereotype threat can elicit regulatory fit, which in turn affects women's leadership aspirations. Future directions and limitations are discussed.
