人类合作可能部分取决于存在愿意承担个人成本去惩罚不合作者的个体。激发这种“利他惩罚”的心理因素尚未完全被理解；一些人认为利他惩罚是一种需要自我控制的、有意识的规范执行行为，而另一些人则声称它主要是由情感驱动的冲动行为。在当前的研究中，我们通过研究最后通牒博弈中冲动选择和利他惩罚之间的关系来解决这个问题。由于神经递质血清素与冲动选择和利他惩罚都有关系，我们研究了操纵血清素对这两种衡量指标的影响。在个体之间，冲动选择和利他惩罚是相关的，并且在血清素减少后都增加了。这些发现意味着利他惩罚反映的是缺乏而非存在自我控制，并表明冲动选择和利他惩罚有共同的神经机制。
Human cooperation may partly depend on the presence of individuals willing to incur personal costs to punish noncooperators. The psychological factors that motivate such 'altruistic punishment' are not fully understood; some have argued that altruistic punishment is a deliberate act of norm enforcement that requires self-control, while others claim that it is an impulsive act driven primarily by emotion. In the current study, we addressed this question by examining the relationship between impulsive choice and altruistic punishment in the ultimatum game. As the neurotransmitter serotonin has been implicated in both impulsive choice and altruistic punishment, we investigated the effects of manipulating serotonin on both measures. Across individuals, impulsive choice and altruistic punishment were correlated and increased following serotonin depletion. These findings imply that altruistic punishment reflects the absence rather than the presence of self control, and suggest that impulsive choice and altruistic punishment share common neural mechanisms.
