Imagery rescripting (IR) is a promising treatment for a variety of disorders, but its working mechanisms remain largely unknown. To elucidate the associative and evaluative learning processes underlying IR, we exposed participants to an aversive film clip followed by an instructed fear-conditioning procedure. The acquired fear memory was subsequently manipulated by either rescripting- (IR) or exposure-based (imaginal exposure; IE) interventions and their effects were examined on subjective and psychophysiological fear responses in three successive studies. Though the interpretation of the results was challenged with respect to the employed analogue IR intervention (Exp 1) and unexpected findings in the control condition (Exp 3), the present results establish preliminary evidence for the hypothesis that IR produces differential effects on fear responding when compared to IE. For example, in line with stimulus devaluation theory, IR effectively reduced subjective distress to the conditioned stimulus (Exp 2). Also, IR resulted in decreased physiological fear responses after fear reinstatement (Exp 3). The findings advance our general understanding of the processes involved in IR and they tentatively indicate that rescripting- and exposure-based treatments may work through different mechanisms. Moreover, this line of research demonstrates the challenges encountered when working with analogue models to test mechanisms of therapeutic change.

调查图像记录对情绪记忆的影响:一系列类似研究

图像改写(IR)是治疗多种疾病的一种有前途的治疗方法,但其工作机制仍然未知。为了阐明IR背后的联想和评估学习过程,我们向参与者展示了一个厌恶的影片剪辑,然后进行了指导性的恐惧调节程序。随后,通过改写(IR)或基于暴露的(想象暴露; IE)干预来操纵获得的恐惧记忆,并在三项连续研究中研究了它们对主观和心理生理恐惧反应的影响。尽管就采用的模拟IR干预(实验1)和对照条件中的意外发现(实验3)而言,对结果的解释提出了挑战,本研究结果为以下假设提供了初步证据:与IE相比,IR对恐惧反应产生不同的影响。例如,根据刺激贬值理论,IR有效地减少了条件刺激的主观困扰(Exp 2)。同样,在恐惧恢复后,IR导致生理恐惧反应减少(实验3)。这些发现提高了我们对IR涉及的过程的一般理解,并初步表明基于记录和暴露的治疗可能通过不同的机制起作用。此外,这条研究线证明了使用模拟模型测试治疗变化机制时遇到的挑战。IR有效地减少了条件刺激的主观困扰(实验2)。同样,在恐惧恢复后,IR导致生理恐惧反应减少(实验3)。这些发现提高了我们对IR涉及的过程的一般理解,并初步表明基于记录和暴露的治疗可能通过不同的机制起作用。此外,这条研究线证明了在使用模拟模型测试治疗变化机制时遇到的挑战。IR有效地减少了条件刺激的主观困扰(实验2)。同样,在恐惧恢复后,IR导致生理恐惧反应减少(实验3)。这些发现提高了我们对IR涉及的过程的一般理解,并初步表明基于记录和暴露的治疗可能通过不同的机制起作用。此外,这条研究线证明了在使用模拟模型测试治疗变化机制时遇到的挑战。
