The management and manipulation of our own social image in the minds of others requires difficult and poorly understood computations. One computation useful in social image management is strategic deception: our ability and willingness to manipulate other people's beliefs about ourselves for gain. We used an interpersonal bargaining game to probe the capacity of players to manage their partner's beliefs about them. This probe parsed the group of subjects into three behavioral types according to their revealed level of strategic deception; these types were also distinguished by neural data measured during the game. The most deceptive subjects emitted behavioral signals that mimicked a more benign behavioral type, and their brains showed differential activation in right dorsolateral prefrontal cortex and left Brodmann area 10 at the time of this deception. In addition, strategic types showed a significant correlation between activation in the right temporoparietal junction and expected payoff that was absent in the other groups. The neurobehavioral types identified by the game raise the possibility of identifying quantitative biomarkers for the capacity to manipulate and maintain a social image in another person's mind.
在他人心目中管理和操纵我们自己的社交形象需要进行困难且理解不深的计算。社交形象管理中一个有用的计算是策略性欺骗：我们为了获得利益而操纵他人对自己的看法的能力和意愿。我们使用人际讨价还价游戏来探究参与者管理其伙伴对他们的看法的能力。这个探测根据参与者表现出的策略性欺骗程度，将受试者群体分为三种行为类型；这些类型也通过游戏过程中测量的神经数据进行区分。最具欺骗性的受试者发出的行为信号模仿了更为良性的行为类型，而他们的大脑在进行欺骗时右侧背外侧前额叶皮层和左侧布罗德曼 10 区显示出不同的激活。此外，策略类型在右侧颞顶联合区的激活与预期收益之间存在显著相关性，而其他组则不存在这种相关性。游戏中确定的神经行为类型使得识别在他人心目中操纵和维持社交形象的能力的定量生物标志物成为可能。
