Twenty-one subjects participated on a volunteer nonpaid basis in a smoking cessation treatment experiment. The subjects were randomly assigned to three groups: one receiving training in covert extinction, one in relaxation, and a waiting list group serving as a control group. Behavioral (number of cigarettes smoked), physiological (pulse rate during treatment sessions) and cognitive (craving for cigarettes) assessments were made during and between sessions. Analysis of variance showed the time variable to be significant for number of cigarettes. Tukey's HSD tests showed a significant decrease in smoking after treatment for all three groups, and also for the two treatment groups until the follow-up occasion, although smoking had returned to a higher level (though not the initial one) after one month. There were also significant differences between the control group and both treatment groups with regards to pulse rate changes in treatment sessions. There was no significant change in craving, although a tendency pointed in the same direction for pulse rates. A tentative conclusion is that covert extinction is not a specific effective treatment method surpassing other nonspecific treatment procedures.
21名受试者以志愿者且无报酬的方式参与了一项戒烟治疗实验。受试者被随机分为三组：一组接受隐蔽消退训练，一组接受放松训练，还有一组作为候补名单组充当对照组。在治疗期间及治疗期间之间进行了行为（吸烟数量）、生理（治疗期间的脉搏率）和认知（对香烟的渴望）评估。方差分析表明，时间变量对吸烟数量有显著影响。图基的HSD检验表明，所有三组在治疗后吸烟量均显著下降，两个治疗组在随访前也是如此，尽管吸烟量在一个月后已回升至较高水平（但不是初始水平）。在治疗期间的脉搏率变化方面，对照组与两个治疗组之间也存在显著差异。对香烟的渴望没有显著变化，尽管脉搏率有朝着相同方向变化的趋势。一个初步结论是，隐蔽消退并不是一种优于其他非特异性治疗程序的特定有效治疗方法。
