What is the definition of altruism in psychology?

Altruism in psychology is defined as the selfless concern for the well-being of others, where individuals act without expecting any personal rewards or benefits in return. This concept emphasizes the importance of empathy and compassion, as altruistic behaviors are often motivated by a desire to help others simply for the sake of helping. It reflects a genuine interest in the welfare of others, contrasting sharply with actions taken for selfish reasons or personal gain.

In the context of the other options, the first choice describes behaviors driven by self-interest, which fundamentally contradicts the essence of altruism. The third option focuses on personal development, which is an individualistic pursuit that does not necessarily involve concern for others. The fourth option highlights behavior motivated by a desire for social approval, again indicating a focus on personal outcomes rather than the unselfish intention that characterizes altruism. Hence, the correct understanding of altruism aligns with the definition of concern for others' well-being without expecting rewards.
