Recent theoretical accounts point to disgust as an important factor in the development and persistence of sexual dysfunctions. This study tested if (i) contingent disgust experiences can render initially sexually arousing stimuli disgusting, and (ii) such acquired disgust responses could be best neutralized via a CS-only extinction or a counterconditioning procedure. Participants (N = 74) were exposed to a differential conditioning procedure that was followed by either a CS-only extinction or a counterconditioning procedure. Erotic films served as the CS+/CS-. A disgusting film served as the US. During the extinction procedure, the CS+ was no longer followed by the disgusting US. During counterconditioning the CS+ was paired with positive stimuli. After conditioning, the CS + elicited lower genital arousal and was rated as significantly more disgusting, less pleasant, and less sexually arousing than the CS-. These diminished genital and subjective sexual arousal responses to the CS+ were successfully restored after both the extinction and the counterconditioning procedure, whereas conditioned feelings of disgust and behavioral avoidance persisted. There was no evidence for differential effectiveness of either procedure. Thus, sexual responses can be attenuated by learned sex-disgust associations and restored by extinction and counterconditioning procedures, but conditioned feelings of disgust seem more resistant.
近期的理论观点指出,厌恶是性功能障碍发生和持续存在的一个重要因素。本研究测试了:(i)偶然的厌恶体验是否会使原本具有性唤起作用的刺激变得令人厌恶;(ii)这种习得的厌恶反应是否能通过仅进行条件刺激消退或反条件作用程序得到最佳中和。参与者(N = 74)接受了差异条件作用程序,随后进行仅条件刺激消退或反条件作用程序。色情影片作为条件刺激增强物/条件刺激减弱物。一部令人厌恶的影片作为无条件刺激。在消退程序中,条件刺激增强物不再与令人厌恶的无条件刺激相随出现。在反条件作用过程中,条件刺激增强物与积极刺激配对。条件作用后,与条件刺激减弱物相比,条件刺激增强物引发的生殖器唤起较低,且被评定为明显更令人厌恶、更不愉快且性唤起程度更低。在消退程序和反条件作用程序后,对条件刺激增强物的生殖器和主观性唤起反应减弱的情况均成功得到恢复,而条件性厌恶情绪和行为回避依然存在。没有证据表明这两种程序的效果存在差异。因此,性反应可因习得的性厌恶关联而减弱,并通过消退和反条件作用程序得以恢复,但条件性厌恶情绪似乎更具抗性。
