Abstract: Psychodrama is an experiential psychotherapy in which role reversal is one of the core techniques. Jacob Levy Moreno, the founder of psychodrama, believes that the role that we play where the self emerges is the self-representation of the individual. According to Morenian role theory, rich practical experience has been accumulated in contemporary psychodrama therapy, but it lacks an explanatory theory to comprehensively explain the beneficial effects of the working mechanism of psychodrama therapy. This study introduces predictive processing theory to explain interpersonal interaction relationship in the process of role reversal, based on the experience of role reversal. This study points out that role reversal is a kind of self-construction process. First, the step of switching brings about the change of the signal type. Second, the model that the protagonist owns has been updated. Third, the model is constructed and generated in the interaction, between the individual self and the other. The conclusion turns out that explaining the structural features of role reversal according to predictive processing theory can promote this technology so as to play a better role in clinical treatment.
