What does altruism primarily boost in individuals who extend help to others?

Altruism primarily boosts self-concept in individuals who extend help to others because self-concept refers to the way individuals perceive themselves based on their values, beliefs, and social identity. When people engage in altruistic behavior, such as helping others, it reinforces a positive view of themselves and affirms their identity as caring or compassionate individuals. This can enhance their overall self-concept, as they recognize themselves as someone who contributes positively to the well-being of others.

Engaging in altruistic acts also provides a sense of purpose and belonging, which are integral components of self-concept. As individuals reflect on their contributions and the impact they have on others' lives, they may develop a stronger and more positive concept of who they are. This growth in self-concept is essential, as it can lead to greater overall life satisfaction and emotional well-being.
