What does altruism mean in social psychology?

Altruism in social psychology refers to selfless concern for the welfare of others, which is precisely the definition provided in the correct answer. This concept emphasizes actions taken to benefit others without any expectation of personal gain or benefit. It embodies an intrinsic motivation to help others, driven by empathy, compassion, or a genuine desire to improve someone else's situation.

The other options suggest motivations that are tied to self-interest or conditionality. Seeking personal gain through helping behaviors implies that the actions are driven by what one can get in return, which contradicts the core idea of altruism. Promoting one's self-image through good deeds suggests a more self-centered motive, where the assistance provided is merely a means to enhance one's reputation rather than a true desire to help. Conditional acts of kindness based on expectations also diverge from altruism, as they imply that the helpful behavior is contingent on anticipating some form of return, thus lacking the purity of selflessness.
