A role (sometimes spelled rôle) or a social role is a set of connected behaviors, rights and obligations as conceptualized by actors in a social situation. It is an expected behavior in a given individual social status and social position. It is vital to both functionalist and interactionist understandings of society.

Social role posits the following about social behavior:

1. People spend much of their lives in groups.
2. Within these groups, people often take distinct positions.
3. Each of these positions can be called a role, with a whole set of functions that are molded by the expectations of others.
4. Formalized expectations become norms when enough people feel comfortable in providing punishments and rewards for the expected behavior.
5. Individuals are generally conformists, and insofar as that is true, they conform to roles.
6. The anticipation of rewards and punishments inspire this conformity.

Determinants and characteristics of social role

Roles may be achieved or ascribed. An achieved role is a position that a person assumes voluntarily which reflects personal skills, abilities, and efforts. Roles are not forced upon the individual; a choice is involved. An ascribed role is a position assigned to individuals or groups without regard for merit but because of certain traits beyond their control (Stark 2007). Roles are forced upon the individual.

Roles can be semi-permanent ("doctor", "mother", "child"), or they can be transitory. A well-known example is the sick role as formulated by Talcott Parsons in the late 1940s. In the transitory "sick role", a person is exempted from his usual roles, but expected to conform to transitory behavioral standards, such as following doctors' orders and trying to recover.

For many roles, individuals must meet certain conditions, biological or sociological. For instance, a boy cannot take the biological role of mother. Other roles require training or experience. For instance, in many cultures doctors must be educated and certified prior to practicing medicine.

Role development can be influenced by a number of additional factors, including social, genetic predisposition, cultural or situational.

• Societal influence: The structure of society often forms individuals into certain roles based on the social situations they choose to experience. Parents enrolling their children in certain programs at a young age increases the chance that the child will follow that role.
• Genetic predisposition: People take on roles that come naturally to them. Those with athletic ability generally take on roles of athletes. Those with mental genius often take on roles devoted to education and knowledge. This does not mean that people must choose only one path, multiple roles can be taken on by each individual (i.e. Mark can be the point guard on the basketball team and the editor of his school newspaper).
• Cultural influence: Different cultures place different values on certain roles based on their lifestyle. For instance, soccer players are regarded higher in European countries than in the United States, where soccer is less popular.
• Situational influence: Roles can be created or altered based on the situation a person is put in outside their own influence.
