 Biddle, in his review of role theory (1986), shows that it represents an important body of social science theorizing and research, and that role concepts come close to being the “lingua franca” (p. 8) of the behavioral sciences.“Role theory concerns one of the most important features of social life, characteristic behavior patterns or roles.It explains roles by presuming that persons are members of social positions and hold expectations for their own behaviors and those of other persons” (Biddle, 1986, p. 67).There are a number of role/social role theories that are meant to describe a variety of social dynamics (Lemay, 1999).
