Abstract
This chapter reviews major psychological research on altruism and prosocial behavior and explore how information can be used to validate and enhance service-learning programs. Contemporary definitions are less restrictive and define altruism simply as a motivational state with the ultimate goal of increasing another welfare. Perhaps the most compelling sociobiological theory is that altruism has evolved because it is beneficial for the welfare of the species. Situational and social factors can also influence an individuals decision about whether to help another in distress. Psychological research on altruism and prosocial behavior can be used to validate and enhance service-learning programs. Teachers can apply the information about effective methods for promoting the development of empathy, altruism, and prosocial behavior in the classroom. Furthermore, research on motivations for volunteering suggests that individuals serve for a variety of egoistic and altruistic reasons.
