2. Social responsibility: Social responsibility is the belief that individuals have a duty to help others in need, regardless of whether or not they have received help in the past. This concept suggests that people are more likely to help those who are perceived as being in a vulnerable or disadvantaged position. For example, a person may be more likely to help a homeless person than a fellow student who forgot their lunch money.

3. Empathy: Empathy refers to the ability to understand and share the feelings of others. People are more likely to help those whom they can empathize with or who they see as similar to themselves. For example, an individual who has experienced homelessness in the past may be more likely to help a homeless person than someone who has never faced such difficulties.

4. Altruism: Altruism is the selfless concern for the well-being of others. People who display altruistic behavior may help others without expecting anything in return. This concept suggests that some individuals are motivated to help others simply out of a sense of compassion or moral duty. For example, a volunteer at a food bank may spend hours distributing food to those in need without expecting any form of compensation.
