有人声称，创伤后应激障碍（PTSD）的症状可以通过眼动脱敏-再处理疗法（EMD-R）得到改善，这是一种涉及个体在想象创伤事件时进行扫视眼动的过程。我们假设，这些眼球运动通过破坏工作记忆的视觉空间画板（VSSP）的功能来降低痛苦图像的生动性，并且通过这样做，它们降低了与图像相关的情感强度。这一假设是通过要求非PTSD参与者在双重任务条件下形成中性和负面图片的图像来测试的。他们的图像不太生动与并发眼球运动和并发空间敲击任务，不涉及眼球运动。在前三个实验中，这些次要任务并没有始终如一地影响参与者对图像的情绪反应。然而，实验4使用个人回忆作为刺激的意象任务，并表现出显着减少情绪反应在相同的双重任务条件下。这些结果表明，如果EMD-R起作用，它通过工作记忆的VSSP减少创伤图像的生动性和情感性。其他视觉空间任务也可能具有治疗价值。
It has been claimed that the symptoms of post-traumatic stress disorder (PTSD) can be ameliorated by eye-movement desensitization-reprocessing therapy (EMD-R), a procedure that involves the individual making saccadic eye-movements while imagining the traumatic event. We hypothesized that these eye-movements reduce the vividness of distressing images by disrupting the function of the visuospatial sketchpad (VSSP) of working memory, and that by doing so they reduce the intensity of the emotion associated with the image. This hypothesis was tested by asking non-PTSD participants to form images of neutral and negative pictures under dual task conditions. Their images were less vivid with concurrent eye-movements and with a concurrent spatial tapping task that did not involve eye-movements. In the first three experiments, these secondary tasks did not consistently affect participants' emotional responses to the images. However, Expt 4 used personal recollections as stimuli for the imagery task, and demonstrated a significant reduction in emotional response under the same dual task conditions. These results suggest that, if EMD-R works, it does so by reducing the vividness and emotiveness of traumatic images via the VSSP of working memory. Other visuospatial tasks may also be of therapeutic value.
