The willingness to cooperate in social interaction often depends on factors such as trustworthiness, reciprocity, and gender, but perhaps also on situational factors such as satiety. Here, we examined Trust Game performance before (fasting condition) and after ingestion of a high-caloric drink (satiety condition) of 37 psychologically healthy male subjects who played the game against individuals of both sexes differing in facial attractiveness. Participants invested significantly fewer money units (MUs) in the fasting condition compared to the satiated condition. Female opposing players received more MUs than males and attractive players more than less attractive ones. Time to arrive at a decision was shorter in the satiated condition than in the fasting condition. These findings indicate that satiety affects social cooperation and suggests that physical needs are prioritized over social cooperation.
在社会互动中合作的意愿往往取决于信任、互惠和性别等因素，但也许还取决于饱腹感等情境因素。在这里，我们在 37 名心理健康的男性被试者进行信任游戏之前（禁食条件）和之后（饱腹条件）分别摄入了高热量饮料，考察了他们的表现，这些被试者与不同面部吸引力的个体进行了游戏。与饱腹条件相比，参与者在禁食条件下投入的货币单位（MU）明显减少。女性对手比男性对手获得的 MU 更多，有吸引力的玩家比吸引力较低的玩家获得的 MU 更多。做出决策的时间在饱腹条件下比在禁食条件下更短。这些发现表明饱腹感会影响社会合作，并表明身体需求优先于社会合作。
