This essay explores how viewing a single Theatre for Young Audiences production might affect the attitudes, values, and/or beliefs of adolescent spectators. Data is drawn from a mixed-methods case study performed with middle school students who viewed a professional performance for young people, and is considered through the lens of cognitive studies in light of advances in research considering the human mirror neuron system. Data suggest it is highly probable that under certain circumstances viewing a single Theatre for Young Audiences production can influence the values of adolescent spectators. The essay concludes by exploring the ethical ramifications of these findings. (Contains 3 figures and 8 footnotes.)
