Analogue studies on intrusion development have found that visuospatial tasks performed during the encoding of aversive information reduce subsequent intrusion development. However, these studies cannot rule out a physical explanation in terms of simple movement. In the current study we addressed this issue. Healthy participants viewed an aversive film while performing a visuospatial movement task, a configurational movement task, or no task. Intrusive images from the film were reported in a diary during the week following film viewing. In line with an information-processing account of posttraumatic stress disorder, intrusion frequency was significantly reduced by the visuospatial movement task but not the configurational movement task compared to no task. This finding supports the role of visuospatial processing specifically in intrusion development.
模拟研究发现，在编码厌恶信息时进行的视空间任务会减少随后的侵入发展。然而，这些研究不能排除简单运动方面的物理解释。在目前的研究中，我们解决了这个问题。健康参与者在观看厌恶电影的同时执行视空间运动任务、形态运动任务或不执行任务。在观看电影后的一周内，通过日记报告电影中的侵入性图像。与创伤后应激障碍的信息处理理论一致，与不执行任务相比，视空间运动任务显著降低了侵入频率，而形态运动任务则没有。这一发现支持了视空间处理在侵入发展中的特定作用。
