Differences are the result of people adapting to social structures. Men usually lived in their own tribe, whereas women often marry to other tribes and assume the role of taking care of children. In competitive environments, women must rely on the support of the tribe to ensure that their children receive better care. In stressful situations, women require company and support more than men do [33]. Thus, for women, identifying the emotions and expressions of others and to expressing themselves quickly and effectively are critical. Women often persuade others to helpPLOS ONE | DOI:10.1371/journal.pone.0158666 June 30,9 /Gender Differences in Emotional Responsethem by expressing strong emotions. For men, their main roles are hunting and protecting family members. Therefore, they must be sensitive to the threat stimuli, including anger, fear, and similar emotions. Gender differences in emotions may have evolved from the need to adapt. Second, although men experience strong emotions, gender stereotypes may have made them unwilling to express themselves honestly. Studies have found that gender stereotypes were likely to lead to the observed gender differences in emotional reactions untrue [34, 35]. Men are likely to assess emotions according to social expectations. Social stereotypes require men to be brave and calm, particularly in the face of anger and horror emotions. Thus, even when men experience very strong physiological arousal, they might not report experiencing strong emotions and their assessment might be relatively conservative to make others think they have not been influenced strongly [36]. In the present study, men had stronger emotional experience on the anger emotion, but they gave this Mdivi-1 biological activity emotion a lower rating. Regarding the horror emotion, men experienced the same extent of horror as women did, but men Anlotinib cost reported a lower rating. This may be another reason as to why gender differences were inconsistent between emotional experience and emotional expressivity. Finally, the participants in this study may have regulated their emotions while watching the emotional videos. Although they were asked to feel their emotions, the possibility of emotion regulation cannot be excluded. Studies have found that men and women often use different strategies to regulate their emotions [37]. Emotional expressivity is reflected in the results of emotional experience after emotional regulation. The gender differences in emotional responses (particularly emotional expressivity) may be due to the gender differences in emotional regulation. Some studies have indicated that women have greater up-regulation of emotional responses to negative stimuli, which means that they often compound negative emotions [38]. The results of the present study might support this. Even when the women did not experience a particularly strong negative emotion, they might have regulated their emotions, interpreting them as more negative, which might explain why their expressivity was more intense for emotions such as anger, horror and disgust. The present study explored gender differences in emotional experience and emotional expressivity for specific types of emotion in more detail than previous studies have. However, several limitations cannot be ignored. First, we discussed physical gender, not psychological or social gender. With the development of society, increasingly more women participate in social competition. Such social changes may affect the development of social.Differences are the result of people adapting to social structures.
