Effects of anger, disgust, and sadness on sharing with others.

Although scholars have suggested that emotions are important for social dilemmas, extant research has neither documented, nor directly studied the influence of anger, disgust, or sadness on choices that involve social dilemmas. What is more, research that looks at social dilemmas typically examines public good dilemmas (e.g., giving resources to a group) and resource dilemmas (e.g., taking resources from a group) separately. Rarely are both dilemmas examined simultaneously, a potential oversight considering research on decision-making implicates give-and-take differences. In this paper, we propose that an important part of cooperating in different social dilemmas involves emotionally guided goals, termed emotivations. For example, emotivations include: in anger, wanting to antagonize others; in disgust, wanting to expel objects and avoid taking anything new; and in sadness, wanting to change one's situation. We suggest that the amount of shared group resources that people give and take is associated with each of these particular emotivations.
