Internal mechanisms, especially those implicating the self, are crucial for the egoism-altruism debate. Self-liking is extended to close others and can be extended, through socialization and reinforcement experiences, to non-close others: Altruistic responses are directed toward others who are included in the self. The process of self-extension can account for cross-situational variability, contextual variability, and individual differences in altruistic behavior.
