 Sociologists, social psychologists, anthropologists, and others have theorized about and carried out empirical research on community, but the psychological approach asks questions about the individual's perception, understanding, attitudes, feelings, etc.about community and his or her relationship to it and to others' participation—indeed to the complete, multifaceted community experience.In his seminal 1974 book, psychologist Seymour B. Sarason proposed that psychological sense of community become the conceptual center for the psychology of community, asserting that it "is one of the major bases for self-definition."
