有人认为，维持视觉空间即时记忆涉及内隐运动过程，类似于言语记忆中的发音回路。另一种解释是，维持是基于空间注意力的转移。在四个实验中，受试者回忆空间记忆广度项目后，间隔，并在第五个实验中，数字广度后，间隔回忆。在间隔期间进行的任务包括触摸视觉目标，重复听到的单词，听来自空间分离位置的音调，指向这些音调，指向视觉目标，并将空间目标分类为来自左侧或右侧。空间跨度回忆受损，如果受试者看到的视觉目标或听到的音调，这种损害增加，如果一个运动反应或分类反应。重复在不同空间位置听到的单词并不会影响回忆，但阅读视觉呈现的单词会干扰回忆。仅就数字广度而言，涉及言语反应的任务损害了回忆。这些结果被解释在一个框架内，积极的空间注意力参与维持空间项目，以便在内存中，并干扰任何任务（视觉，听觉，知觉，电机），也使空间注意力的要求。
It has been suggested that maintenance in visuospatial immediate memory involves implicit motor processes that are analogous to the articulatory loop in verbal memory. An alternative account, which is explored here, is that maintenance is based on shifts of spatial attention. In four experiments, subjects recalled spatial memory span items after an interval, and in a fifth experiment, digit span was recalled after an interval. The tasks carried out during the interval included touching visual targets, repeating heard words, listening to tones from spatially separated locations, pointing to these tones, pointing to visual targets, and categorizing spatial targets as being from the left or right. Spatial span recall was impaired if subjects saw visual targets or heard tones, and this impairment was increased if either a motor response or a categorical response was made. Repeating words heard in different spatial locations did not impair recall, but reading visually presented words did interfere. For digit span only, the tasks involving a verbal response impaired recall. The results are interpreted within a framework in which active spatial attention is involved in maintaining spatial items in order in memory, and is interfered with by any task (visual, auditory, perceptual, motor) that also makes demands on spatial attention.
