Developing the ability to regulate emotions is important for young children, which involves across psychological and neuroendocrine subsystems. Cortisol reactivity is related with not only inhibited temperament but also tense/angry affect for American children (Donzella et al., 2000). To determine the relationship between cortisol reactivity and behavior indicating anger/sadness in different cultural context, we analyzed cortisol reactivity of AUCi (Fekedulegn et al., 2007) of Challenging task for 41 Japanese children. Results showed that children just standing up but still staying in the room were higher cortisol reactivity significantly than children running away from the room after losing a game. Moreover, children crying silently were higher cortisol reactivity significantly than children without crying, but there was not significant between children crying loudly and children without crying. These results suggest that Japanese children who express strongly their emotions by behavior indicate less cortisol reactivity than children who hesitate to express their emotions.
