What is defined as a person's voluntary act of aiding another individual?

The concept that accurately describes a person's voluntary act of aiding another individual is prosocial behaviour. This term encompasses a wide range of positive actions intended to benefit others, including helping, sharing, donating, volunteering, and cooperating. The key aspect of prosocial behaviour is that it is performed willingly and without the expectation of compensation; it is driven by a desire to help or improve the well-being of others.

In the context of psychology, prosocial behaviour is often studied in relation to various motivations, including empathy and altruism, and it examines the conditions under which individuals choose to engage in such behaviours. Understanding prosocial behaviour allows researchers and practitioners to explore ways to encourage positive social interactions and community involvement, which can lead to stronger social bonds and a more supportive society.
