Role theory is a perspective in sociology and in social psychology that considers most of everyday activity to be the acting out of socially defined categories (e.g., mother, manager, teacher). Each social role is a set of rights, duties, expectations, norms and behaviours that a person has to face and fulfill. The model is based on the observation that people behave in a predictable way, and that an individualâs behavior is context specific, based on social position and other factors.
