In everyday life, assumptions about our peers’ as well as our own personality shape social interactions. We investigated whether self-rated personality and inferences drawn from partners’ faces influence economic decisions. Participants (N = 285) played the trust game in the role of the trustor as well as the ultimatum game in the role of the proposer and interacted with trustees and receivers represented by prototypical personality faces. Participants also evaluated both their own traits and the personality of the faces. In the trust game, trustees represented by faces rated higher on agreeableness yielded higher transferred amounts. This effect was more pronounced for trustors low on dispositional trust, whereas trustors high on dispositional trust did not relate their decisions to the faces. Trustees represented by faces rated higher on conscientiousness yielded higher transferred amounts only for trustors high on dispositional anxiety. In the ultimatum game, receivers represented by faces rated higher on conscientiousness yielded lower offers only for proposers high on dispositional assertiveness. These results extend previous findings on the inferences drawn from facial features and the influence of personality on decision-making. They highlight the importance of considering the personality of both interaction partner, as well as potential interactions of players traits.

在你的脸上—经济决策中的人格特质与典型的人格面孔互动

在日常生活中，关于我们的同龄人以及我们自己的性格的假设会影响社会互动。我们调查了自评型人格和从伴侣面孔中得出的推论是否会影响经济决策。参与者（N = 285）扮演了委托人角色的信任博弈以及提议者角色的最后通game博弈，并与原型人格面孔所代表的受托人和接受者进行了互动。参与者还评估了自己的特征和面孔的个性。在信任博弈中，以可接受度较高的面孔表示的受托人产生了更高的转账金额。对于缺乏处置信任的信任者而言，这种影响更为明显，而缺乏处置信任的信任者则没有将其决策与面孔联系起来。以尽责程度较高的面孔表示的受托人仅对处置性焦虑较高的托拉斯产生较高的转账金额。在最后通game博弈中，以认真态度较高的面孔表示的接收者只为处事果断自信较高的提议者提供较低的出价。这些结果扩展了先前的发现，这些发现来自于从面部特征得出的推论以及人格对决策的影响。他们强调了考虑双方互动伙伴的个性以及玩家特质的潜在互动的重要性。这些结果扩展了先前的发现，这些发现来自于从面部特征得出的推断以及人格对决策的影响。他们强调了考虑双方互动伙伴的个性以及玩家特质的潜在互动的重要性。这些结果扩展了先前的发现，这些发现来自于从面部特征得出的推论以及人格对决策的影响。他们强调了考虑双方互动伙伴的个性以及玩家特质的潜在互动的重要性。
