Role Theory proposed that human behavior is guided by expectations held both by the individual and by other people. The expectations correspond to different roles individualsperform or enact in their daily lives, such as secretary, father, or friend. For instance, most people hold pre-conceived notions of the role expectations of a secretary, which might include: answering phones, making and managing appointments, filing paperwork, and typing memos. These role expectations would not be expected of a professional soccer player.
Individuals generally have and manage many roles. Roles consist of a set of rules or norms that function as plans or blueprints to guide behavior. Roles specify what goals should be pursued, what tasks must be accomplished, and what performances are required in a given scenario or situation. Role theory holds that a substantial proportion of observable, day-to-day social behavior is simply persons carrying out their roles, much as actors carry out their roles on the stage or ballplayers theirs on the field. Role theory is, in fact, predictive. It implies that if we have information about the role expectations for a specified position (e.g., sister, fireman, prostitute), a significant portion of the behavior of the persons occupying that position can be predicted.
What’s more, role theory also argues that in order to change behavior it is necessary to change roles; roles correspond to behaviors and vice versa. In addition to heavily influencing behavior, roles influence beliefs and attitudes; individuals will change their beliefs and attitudes to correspond with their roles. For instance, someone over-looked for a promotion to a managerial position in a company may change their beliefs about the benefits of management by convincing him/herself that they didn’t want the additional responsibility that would have accompanied the position.
Many role theorists see Role Theory as one of the most compelling theories bridging individual behavior and social structure. Roles, which are in part dictated by social structure and in part by social interactions (see the two approaches outlined below), guide the behavior of the individual. The individual, in turn, influences the norms, expectations, and behaviors associated with roles. The understanding is reciprocal and didactic.
