"In addition to more widely recognized theatrical movements, such as the Roman mime, Italian Commedia dell'Arte, Augusto Boal's Theatre of the Oppressed, Viola Spolin's Theatre Games and Keith Johnstone's Theatresports, the inclusion of lesser known (and marginal) practices, such as Japanese renga, Nigerian Apidan and Jacob Levy Moreno's psychodrama, further elucidates and complicates improvisation's generic qualities."
