Abstract:  Asserts that the desensitization (DSN) process used to explain how high exposure to vicarious violence effectively results in a psychological blunting of the normal emotional responses to violent events and that desensitization theory leaves numerous questions unexplained. A new model is presented to explain the DSN to TV violence in terms of conditioning theory involving ideational processes. It is proposed that DSN occurs when the stimulus or stimuli no longer remain important, stimulating, and/or novel (i.e., the affective elements have habituated producing an insufficient orienting reflex). In terms of viewing violence on TV, it is asserted that DSN occurs when an expectation (formed through past experience) determines the subsequent behavioral response by failing to initiate a psychophysiological reaction to the TV violence.
