“…Consequently, it would be remiss not to acknowledge it here. A review of this extensive related literature reveals three general categories of research on the effects of role play: role playas a means of producing attitude and opinion change (Carlson, 1956;Cohen, 1964;Culbertson, 1957;Elms, 1967;Elms & Janis, 1965;Hovland, Janis, & Kelley, 1953;Janis & Gilmore, 1965;Janis & King, 1954;Kelman, 1953;King &Janis, 1956); role playas a means of producing personality and behavioral change (Efran & Korn, 1969;Friedman, 1971;Harrow, 1952;Janis & Mann, 1965;Kelly, Blake, & Stromberg, 1957;Maier, 1952;Mann, 1958;Mann & Mann, 1960;McGuire, 1964;Moreno, 1940Moreno, , 1946Moreno, , 1952Moreno, , 1955Moreno, , 1962Zimbardo, 1965); and role playas a research method (Cooper, 1976;Geller, 1978;Greenberg, 1967;Kelman, 1967;Spencer, 1978;Vinacke, 1954). This research has generally indicated that role play can be effectively employed in changing attitudes and opinions, that it is a useful therapeutic process when applied to specific situation problems, and that as a research method it presents problems of experimental validity.…”
