Prosociality is fundamental to social relationships, but providing it indiscriminately risks exploitation by egoists. Past work demonstrates that individuals avoid these risks through a more selective form of prosociality, cooperating less and sharing fewer resources with egoists (e.g. Axelrod & Hamilton, 1981). The evolution of cooperation. Science, 211(4489), 1390–1396). We extend this work to explore whether individuals experience reduced prosocial affective and physiological responses to egoists in situations where they are suffering. In two studies, participants learned of a target’s egoistic or non-egoistic traits, and then encountered the target suffering. Suffering egoists evoked less compassion in others than non-egoists and elicited physiological responses that diverged from patterns associated with compassion and social engagement (reduced heart rate and greater respiratory sinus arrhythmia activity). Participants' feelings of distrust toward egoists explained these attenuated emotional and physiological responses. These results build upon studies of prosocial behavior by suggesting that individuals experience reduced prosocial emotional and physiological responses toward suffering egoists.
Do people benefit when they think their partner has made a sacrifice for the relationship? In a multimethod study of 80 couples, we examined whether people can detect when their partner suppresses their emotions and if perceived partner suppression is costly for the recipient of sacrifice. When people listened to their partner recall an important sacrifice in the lab and when people thought their partner sacrificed in daily life, they thought that their partner was less authentic the more they perceived them to have suppressed their emotions. In turn, perceived partner inauthenticity during sacrifice was associated with poorer personal well-being and relationship quality. These effects persisted over time with perceived partner suppression predicting poorer relationship quality 3 months later. The results were independent from the influence of an actor’s projection of their own suppression and their partner’s actual suppression. Implications for research on emotion regulation and close relationships are discussed.
