As one of the founding principles of Acceptance and Commitment Therapy (ACT), cognitive defusion is a contextual control of language, but it is not clear which behavioural process would allow such defusion. Two experiments are presented which analyse that process using a word repetition exercise.
Experiment 1 was performed with 30 randomised participants, using a factorial between-groups (4x2) with repeated measures design: Group 1 = milk-milk-milk exercise; 2 = emotional word repetition; 3 = milk-to-emotional word shaping; and 4 = control without intervention. Questionnaires were applied on thoughts, emotional regulation, and experiential avoidance, in addition to the evaluation of 20 images suggesting emotions. In Experiment 2, 78 participants were randomised using the same 4x2 design, and also 60 images with a proven emotional reactivity were used.
Experiment 1 did not show changes in any of the variables, nor a decrease in emotional assessment, which should occur according to the theory behind ACT. In Experiment 2, no significant changes between the groups and no pre-post changes appeared, except in latency time.
The lack of replication of the defusion process is discussed, along with the mixed results of other studies.
作为接纳与承诺疗法（ACT）的基本原则之一，认知解离是一种语言的语境控制，但目前尚不清楚哪种行为过程可以实现这种解离。本研究通过重复单词练习来分析这个过程，共进行了两项实验。
实验 1 共纳入 30 名随机分组的参与者，采用 4x2 析因组间设计，其中包括重复测量：组 1=牛奶-牛奶-牛奶练习；组 2=情绪词汇重复；组 3=牛奶到情绪词汇的塑形；组 4=无干预的对照组。研究采用问卷评估思维、情绪调节和经验回避，并评估 20 张暗示情绪的图片。在实验 2 中，使用相同的 4x2 设计对 78 名参与者进行了随机分组，同时使用了 60 张具有情绪反应性的图片。
实验 1 中没有观察到任何变量的变化，也没有观察到 ACT 理论所预测的情绪评估的下降。实验 2 中，除了潜伏期时间外，各组之间没有显著变化，也没有出现前后变化。
该研究讨论了缺乏对解离过程的复制问题，以及其他研究的混合结果。
