人类有一种通过与他人比较来检查自己的能力和结果来评估自己的动力。本研究探讨了向上社会比较的情感和神经相关性（与拥有更多的人相比）和向下的社会比较（与那些拥有较少的人相比）在一个互动的机会游戏中对志愿者进行了两个实验，结果表明，即使参与者输了钱，如果另一个玩家输了更多的钱，他们也会表现出喜悦和幸灾乐祸（幸灾乐祸）。另一方面，当他们真的赢了钱，但另一个球员赢得更多，他们表示羡慕。这种模式也表现在腹侧纹状体的差异BOLD反应。比较实际收益和相对收益之间的激活表明，即使当一个人赔钱时，仅仅添加关于另一个人更大损失的信息可能会增加腹侧纹状体的激活，使这些激活与实际收益相似。在社会比较的情绪后果中起着中介作用[Brain Mapp 31.1741-1750，2010]。(C)2010 Wiley-Liss，Inc.
Humans have a drive to evaluate themselves by examining their abilities and outcomes in comparison to others The present study examined the emotional and neural correlates of upward social comparison (comparison with those who have more) and downward social comparison (comparison with those who have less) Two experiments were conducted with volunteers in an interactive game of chance, in which a putative player won or lost more money than the participant The results showed that even when participants lost money, they expressed joy and schadenfreude (gloating) if the other player had lost more money. On the other hand when they actually won money, but the other player had won more they expressed envy. This pattern was also demonstrated in a differential BOLD response in the ventral striatum. Comparing the activations between an actual gain and a relative gain indicated that even when a person loses money, merely adding information about another person's greater loss may increase ventral striatum activations to a point where these activations are similar to those of an actual gain We suggest that the ventral striatum. plays a role in mediating the emotional consequences of social comparison Hum Brain Mapp 31.1741-1750, 2010.
