On each of three sessions, 5s viewed 20 presentations of an isolated accident (experimental group) or a benign (control group) motion picture scene. At the end of each session, 5s also saw the complete movie from which these scenes were taken. Skin conductance, self-reported distress, and, to a lesser extent, heart rate showed considerable carry-over of habituation from the accident scene viewe...
