Final answer:
The social-responsibility norm is the expectation that individuals will help those who depend on them. It is a social rule that encourages aiding others in need and is an essential concept in social psychology.
Step-by-step explanation:
The expectation that people will help those who depend on them is known as the social-responsibility norm. This concept is a part of social psychology, which examines how the thoughts, feelings, and behaviors of individuals are influenced by the actual, imagined, or implied presence of others. The social-responsibility norm is a societal rule that tells us to help others when they are in need and when they depend on us, especially if the persons in need are perceived as not being responsible for their predicament. This norm is distinct from concepts like the bystander effect, which suggests people are less likely to provide help to a victim when other observers are present, due to a diffusion of responsibility.
