To investigate the metaphorical associations and mapping dynamics between geometric shapes and social roles,the study used two Stroop experiments for bidirectional validation.It was found that there was a metaphorical consistency effect between the square and the social role"father/male",the circle and the social role"mother/female",which emphasized the bidirectional mapping of the relationship between geometric shapes and social role in the cognitive system and provided new insights into the complexity of metaphors.The Event-Related Potentials(ERPs)results demonstrate that incongruent conditions elicit more pronounced N450 and Late Positive Component(LPC)responses compared to congruent conditions,which provided clues for understanding the neural mechanisms underlying metaphorical effects.
