Children with histories of high and low exposure to television (and the violence therein) were exposed to a moderately violent film. Measures of autonomic response (skin conductance and blood volume pulse amplitude) were taken before and during their exposure to the violent film. Over both measures and in another replicated study, the high TV exposure subjects were found to be significantly less "aroused" autonomically, suggesting a limited but still definite and measurable desensitization to filmed violence. Since the subjects had had no, or no recent, exposure to the particular film, the results suggest the possibility of a generalizing effect for the desensitization that occurred. (Author)
