Definition of altruism. 1  1 : unselfish regard for or devotion to the welfare of others charitable acts motivated purely by altruism. 2  2 : behavior by an animal that is not beneficial to or may be harmful to itself but that benefits others of its species.
Altruism is when a person helps another without any interest in gaining benefits. In prosocial behaviour, there is a tendency to expect psychological or social rewards for helping behaviour. However, in altruism this is not the case.here is a difference between altruism and prosocial behaviour. â¢ In prosocial behaviour even though it is helping another there is a chance of gaining intrinsic or extrinsic reward. Also, the possibility for the helper to expect such a reward is possible. Simply in prosocial behaviour there is a gain for both parties.
