Mirroring, role-playing and other psychodramatic techniques are based on these stages. Moreno believed that psychodrama could be used to help individuals continue their emotional development through the use of these techniques. Related concepts Sociometry Moreno's term sociometry is often used in relation to psychodrama. By definition, sociometry is the study of social relations between individuals—interpersonal relationships. It is, more broadly, a set of ideas and practices that are focused on promoting spontaneity in human relations. Classically, sociometry involves techniques for identifying, organizing, and giving feedback on specific interpersonal preferences an individual has. For example, in a psychodrama session, allowing the group to decide whom the protagonist shall be employs sociometry. Moreno is also credited for founding sociodrama. Though sociodrama, like psychodrama, utilizes the theatrical form as means of therapy, the terms are not synonymous. While psychodrama focuses on one patient within the group unit, sociodrama addresses the group as a whole. The goal is to explore social events, collective ideologies, and community patterns within a group in order to bring about positive change or transformation within the group dynamic. Moreno also believed that sociodrama could be used as a form of micro-sociology—that by examining the dynamic of a small group of individuals, patterns could be discovered that manifest themselves within the society as a whole, such as in Alcoholics Anonymous. Sociodrama can be divided into three main categories: crisis sociodrama, which deals with group responses after a catastrophic event, political sociodrama, which attempts to address stratification and inequality issues within a society, and diversity sociodrama, which considers conflicts based on prejudice, racism or stigmatization. Drama therapy The other creative arts therapies modality drama therapy, which was established and developed in the second half of the past century, shows multiple similarities in its approach to psychodrama, as to using theatre methods to achieve therapeutic goals. Both concepts however, describe different modalities. Drama therapy lets the patient explore fictional stories, such as fairytales, myths or improvised scenes, whereas psychodrama is focused on the patient's real-life experience to practice "new and more effective roles and behaviors" (ASGPP). History Jacob L. Moreno (1889–1974) is the founder of psychodrama and sociometry, and one of the forerunners of the group psychotherapy movement. Around 1910, he developed the Theater of Spontaneity, which is based on the acting out of improvisational impulses. The focus of this exercise was not originally on the therapeutic effects of psychodrama; these were
