三个实验研究了眼睛和肢体运动在空间工作记忆信息维持中的作用。在实验1中，反射性扫视干扰空间位置的记忆广度，但不干扰字母的记忆广度。在实验2中，三种不同类型的眼动（反射性眼跳，亲眼跳，反眼跳）干扰工作记忆的程度相同。在这三种情况下，空间工作记忆比文字工作记忆受到的影响更大。这两个实验的结果表明，眼球运动干扰空间工作记忆主要是通过破坏过程定位在视觉空间画板。在实验3中，肢体运动，同时保持固定产生尽可能多的干扰空间工作记忆的反射性扫视。这些结果表明，眼动产生的干扰不是其视觉后果的结果。相反，所有空间定向运动似乎对视觉空间工作记忆有类似的影响。
Three experiments examined the role of eye and limb movements in the maintenance of information in spatial working memory. In Experiment 1, reflexive saccades interfered with memory span for spatial locations but did not interfere with memory span for letters. In Experiment 2, three different types of eye movements (reflexive saccades, pro-saccades, and anti-saccades) interfered with working memory to the same extent. In all three cases, spatial working memory was much more affected than verbal working memory. The results of these two experiments suggest that eye movements interfere with spatial working memory primarily by disrupting processes localised in the visuospatial sketchpad. In Experiment 3, limb movements performed while maintaining fixation produced as much interference with spatial working memory as reflexive saccades. These results suggest that the interference produced by eye movements is not the result of their visual consequences. Rather, all spatially directed movements appear to have similar effects on visuospatial working memory.
