Final answer:
Altruism refers to selfless prosocial behavior where one helps others without expecting personal benefits, motivated by empathy and concern for others' well-being.
Step-by-step explanation:
Behavior meant to help another person without regard for self-interest is known as altruism. Altruism is a form of prosocial behavior that is motivated by the selfless helping of others, often without any anticipated personal benefit. Research indicates that there can be various motivations for helping others, including empathy, which is the capacity to understand and feel what another person is experiencing. While after helping, people may feel good about themselves, this is generally viewed as a consequence of altruism rather than the cause. Altruistic behaviors are observed not only in humans but also in the animal kingdom, though the nuances of these behaviors can be complex and are subject to ongoing scientific investigation.
