Edited moving pictures — such as movies and television — have long been a source of enjoyment; however, few researchers have studied the psychology behind our ability to understand film. In this article, Smith, Levin, and Cutting investigate how we perceive movies. They specifically focus on continuity editing — a type of editing that allows the viewer to seamlessly integrate different perspecitves of a scene. The authors discuss how research on individual and group patterns of attention can and are being utilized to make scene editing as seamless as possible for the viewer.
