title: The time course from gender categorization to gender-stereotype activation.
abstract: Social categorization is the foundation of stereotype activation, and the process from social categorization to stereotype activation is rapid. However, the time from social categorization to stereotype activation is unknown. This study involves a real-time measurement of the time course of gender-stereotype activation beginning with gender categorization using event-related potential technology with a face as the priming stimulus. We found that 195 ms after a face stimulus was presented, brain waves stimulated by male or female gender categorization showed a clear separation, with male faces stimulating larger N200 waves. In addition, 475 ms after a face stimulus appeared or 280 ms after the gendercategorization process occurred, gender-stereotype-consistent and gender-stereotype-inconsistent stimuli were distinct, with gender-stereotype-inconsistent stimuli inducing larger N400 waves. These results indicate that during gender-stereotype activation by face perception, gender categorization occurs approximately 195 ms after seeing a face stimulus and a gender stereotype is activated at approximately 475 ms.
