Moving the self and others to do good: The emotional underpinnings of prosocial behavior.

The functioning of social collectives hinges on the willingness of their members to cooperate with one another and to help those who are in need. Here, we consider how such prosocial behavior is shaped by emotions. We offer an integrative review of theoretical arguments and empirical findings concerning how the experience of emotions influences people's own prosocial behavior (intrapersonal effects) and how the expression of emotions influences the prosocial behavior of others (interpersonal effects). We identified research on five broad clusters of emotions associated with opportunity and affiliation (happiness, contentment, hope), appreciation and self-transcendence (gratitude, awe, elevation, compassion), distress and supplication (sadness, disappointment, fear, anxiety), dominance and status assertion (anger, disgust, contempt, envy, pride), and appeasement and social repair (guilt, regret, shame, embarrassment). Our review reveals notable differences between emotion clusters and between intrapersonal and interpersonal effects. Although some emotions promote prosocial behavior in the self and others, most emotions promote prosocial behavior either in the self (via their intrapersonal effects) or in others (via their interpersonal effects), suggesting trade-offs between the functionality of emotional experience and emotional expression. Moreover, interpersonal effects are modulated by the cooperative versus competitive nature of the situation. We discuss the emerging patterns from a social-functional perspective and conclude that understanding the role of emotion in prosociality requires joint attention to intrapersonal and interpersonal effects.
