The interactionist approach to deviance is summarized drawing heavily on Blumer’s conception of continual self-indication and Becker’s examination of the socialization of deviants. The concepts of the self, the definition of the situation, significance, reciprocity and interaction constitute an idea of a human being who is best defined by such terms as homo reciprocus (man in interaction), homo symbolicus (symbolic man), homo faber (man the maker) and homo aestimans (man who evaluates). Symbolic interactionism is used to guide professional assessment and intervention by human services professionals. Correction officers, social workers, counselors, street workers, therapists are positions that would apply the ideas presented in the article.
