在他人心目中对我们自身社会形象的管理和操纵需要复杂且鲜为人知的考量。在社会形象管理中一种有用的考量是策略性欺骗：我们为了利益而操纵他人对我们自身看法的能力和意愿。我们利用一个人际讨价还价博弈来探究参与者管理其伙伴对他们看法的能力。这个探究根据参与者所展现出的策略性欺骗水平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所测量的神经数据得以区分。最具欺骗性的受试者会发出模仿一种更温和行为类型的行为信号，并且在他们实施欺骗时，其大脑的右侧背外侧前额叶皮质和左侧布罗德曼10区呈现出不同的激活状态。此外，策略型受试者在右侧颞顶联合区的激活与预期收益之间显示出显著的相关性，而其他组则没有这种相关性。通过该游戏所确定的神经行为类型增加了确定用于在他人心目中操纵和维持社会形象能力的定量生物标志物的可能性。
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.
