Explore the impact of gender stereotypes in mathematics on individuals’ perception andjudgment of others. The implicit association paradigm was introduced, and explicit and implicit methodswere used to examine the impact of gender stereotypes in college students’ mathematics on characterevaluation. Experiment 1 used self-report methods to examine the impact of explicit mathematicsgender stereotypes on character evaluations. The results showed that men have higher ability evaluationsthan women. In the case of stereotype inconsistency, both men and women were evaluated with highenthusiasm. Experiment 2 used experiments to measure the influence under implicit conditions andfound a significant difference in the reaction times of male and female subjects when evaluating maleability words and enthusiasm words. There are implicit gender differences in subjects’ reactions to men’santi-stereotypical enthusiasm and negative words.
