How is a group defined in social psychology?

In social psychology, a group is defined as two or more individuals who are interacting and interdependent. This definition emphasizes the importance of interaction, which is fundamental to the concept of a group. Interaction among individuals implies that they influence and are influenced by one another, creating a dynamic context where social processes can occur. Interdependence signifies that the individuals rely on each other to achieve common goals or fulfill roles within the group, fostering a sense of connection and collective identity.

The other definitions touch on aspects that do not capture the essence of what constitutes a group. For instance, a collection of individuals working independently or a set of people who have no interaction fails to recognize the critical role of personal connections and collaboration that characterize a true group dynamic. A random gathering does not imply the necessary interaction or interdependence, as it could consist of individuals with no lasting relationships or purpose. Therefore, the definition focusing on interaction and interdependence accurately reflects the structured social unit recognized in social psychology.
