The document discusses theories about why and when people help others and how to increase helping behaviors. It covers:
1) Reasons for helping including social exchange of rewards, social norms of reciprocity and responsibility, and evolutionary psychology of kin selection and reciprocity.
2) Factors influencing when helping occurs, such as the bystander effect where more bystanders means less helping, and time pressures reducing assistance.
3) Individual differences in helping, with personality traits like empathy and efficacy predicting more assistance, and religious faith enabling long-term altruism.
4) Ways to boost helping by reducing ambiguity, using persuasion techniques to increase responsibility or guilt, and teaching altruism directly.
