Final answer:
Social influence is a significant force when an individual's behavior is visible because people tend to comply with the expectations of their group. Deindividuation and conformity are two factors that influence group behavior.
Step-by-step explanation:
Social influence is a significant force when an individual's behavior is visible because people tend to comply with the expectations of their group.
When individuals are part of a group, they may experience deindividuation, which can lead to a reduction in accountability and a sense of self. This may result in behaviors like mob or riot-like actions.
In addition, conformity plays a role in group behavior. Conformity refers to the extent to which an individual complies with group norms or expectations. People may conform to fit in with the group or gain information from the group.
