Abstract: | In a within-groups design, four obsessive-compulsive patients imagined four different types of scenes: (1) exposure to feared situations; (2) exposure to feared situations followed by engaging in ritualistic behavior: (3) engaging in ritualistic behavior without provocation; and (4) neutral situations. Each scene type was presented three times with order of presentation randomized. Beat-by-beat heart rate samples were taken during the visualization of each scene and converted to second-by-second heart rate. An examination of second-by-second heart rate for each scene type suggested that scenes involving exposure to feared situations elicited defensive responses (DR), whereas those that did not elicited orienting responses (OR). The implications of these results for compulsive behavior, the fear-reduction model and Sokolov's (1963) OR-DR model, are briefly discussed. |
