Students experience many changes during the transition to college. This transition may negatively affect a student’s school and math self-concept, particularly when their gender group is negatively stereotyped in the academic domain (e.g., women in math). In this study, college students were primed to think about an academic transition or a daily routine. Then participants were primed with gender stereotype threat or no threat followed by a math task. Results found women rated their math self-concept lower than men. Women also scored lower on the math task than men. As hypothesized, women reported lower math self-concept scores than men only in the transition condition; no gender differences emerged in school self-concept scores.
