“Patterned behaviors signifying to the individual (and sometimes to others) that he or she is in the process of exiting one role and preparing to enter another.” (Desrochers & Sargent)
Ashforth, Kreiner, and Fugate (2000) discuss transition rituals in the context of “rites of passage” in the following excerpt: “Van Gennep (1960) defined rites of passage as rituals or ceremonies that facilitate movement of one or more individuals from one role to another. Rites may include the presence and involvement of others, the manipulation of emotionally charged symbols (e.g., settings, props, clothing), and more or less formulaic behavior. The rites signal, both to the individual and to members of the applicable role set(s), the change in roles and associated identities…Van Gennep’s (1960) rites of passage comprise three types: rites of separation, which facilitate role exit; rites of transition, which facilitate psychological (and, if appropriate, physical) movement; and rites of incorporation, which facilitate role entry…Psychological and physical movement are facilitated by rites of transition…commuting can be viewed as a rite of transition involving temporal and spatial boundaries” (pp. 478-479). (Desrochers).
