This research was performed to test Lang's theory (1979a) about psychophysiological changes accompanied with the emotional imagery. The purposes were to reconfirm his observation, and to investigate further the effects of response- and stimulus-oriented trainings on psychophysiological responses to various propositional structures of imagery when subjects were asked to imagine freely instead of using given imagery scripts. Twenty subjects were devided into stimulus and response groups. After a relaxation training, the stimulus and the response groups were given the stimulus and the response-oriented trainings, respectively. All subjects then, took, the script imagery test and the free imagery test. Measures in IBI, respiration, EMG, and temperature during neutral, fear, and action scenes in the test battery were analysed. The results generally support Lang's hypothesis, that the response-oriented imagery is more effective in eliciting psychophysiological changes than the stimulus-oriented imagery. For the free imagery condition, no physiological differences between two oriented groups were apparent in all scenes. The results however, suggested, that the propositional structure of imagery were altered by the proposition oriented training.
