Bystander response refers to how individuals react or intervene in situations where they witness someone in distress or in need of help. This research area explores the factors that influence a person's decision to assist or not assist in such situations, including social norms, situational factors, personal characteristics, and perceived risks. Understanding bystander response is important for promoting prosocial behavior and preventing harm in various contexts, such as bullying, emergencies, and public safety incidents. Researchers in this area often conduct studies to identify effective strategies for increasing bystander intervention and reducing bystander apathy.
