A fine‐grain analysis of autonomic responses are presented with the purpose of extending the conclusions from a previously published paper (Christianson & Nilsson, 1984) on emotional and memorial responses to traumatic visual stimuli. Control subjects were presented with a series of 18 slides of neutral faces, whereas the experimental subjects were presented with six slides of horrible facial injuries in positions 7–12, interspersed between six slides of neutral faces in the beginning, and six slides of neutral faces at the end of the series. The time course of heart rate (HR) and skin conductance (SC) during stimulus presentation was recorded. These data showed an initial pattern of increase in SC, but not in HR. This pattern was subsequently replaced by a combined increase in both SC and HR. The results are discrepant to previous work and are interpreted as effects of not informing the subjects about the gruesome slides to be presented.
