在29名女大学生的实验1中，设计了一种自动进行系统脱敏的装置，在减少恐惧行为方面与现场治疗师一样有效，这表明有效的脱敏并不依赖于同时发生的人际互动。对脱敏过程的广泛心理生理学分析表明，s的恐惧信号与自主神经觉醒的增加有关，并且重复呈现恐惧项目伴随着自主神经活动的减少。心率水平、反应和对恐惧刺激的习惯程度似乎与脱敏的成功有关。在实验II中，有5名男性和15名女性受试者，当项目作为可视化场景呈现时，为脱敏而开发的焦虑等级产生了自主梯度，该梯度随恐惧内容和报告的可视化清晰度而变化。结果支持脱敏通过学习改变自主、大肌肉运动和语言反应的观点。（PsycInfo数据库记录(c) 2022 APA，版权所有）
In Exp. I with 29 female undergraduates, an apparatus designed to administer systematic desensitization automatically was as effective as a live therapist in reducing phobic behavior, suggesting that effective desensitization is not dependent on a concurrent interpersonal interaction. An extensive psychophysiological analysis of the desensitization process showed that Ss' fear signals are associated with an increment in autonomic arousal, and that repreated presentation of fear items is accompanied by reduction in autonomic activity. Heart rate levels, responses, and degree of habituation to fear stimuli appeared related to success of desensitization. In Exp. II with 5 male and 15 female Ss, the anxiety hierarchies developed for desensitization yielded autonomic gradients, when the items were presented as visualized scenes, that varied with fear content and reported clarity of visualization. Results support the view that desensitization modifies autonomic, as well as gross motor and verbal responses, through learning.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
