What is the definition of a small group in sociology?

In sociology, a small group is defined as a collection of individuals who interact with each other simultaneously, allowing for direct and personal communication. This interaction is key to the dynamics of a small group, as it fosters relationships, cooperation, and a sense of belonging among its members. It often leads to shared goals, mutual influence, and a capacity for influencing one another's behaviors and attitudes, which are integral features of small group interactions.

The other options do not capture the core attributes of a small group: the inability to communicate contradicts the essence of group cohesion, a large gathering does not facilitate the necessary interpersonal communication characteristic of small groups, and a collection of unrelated individuals lacks the intentional interaction and connection that defines the small group experience. These collective elements underscore the importance of synchronous engagement among members, which is foundational to the concept of a small group in sociology.
