本研究探讨是否存储的视觉构造的图像需要执行资源。实验1的目的是确定一个视觉构建的模式（成像任务）可以存储多久，没有足够的排练在1秒，6秒和11秒的时间间隔。结果表明，在11秒的时间间隔内，记忆性能受到显著破坏。使用这个时间间隔，在实验2中比较了成像任务和感知任务（需要暂时存储感知模式）的记忆性能。这两项记忆任务在难度上是相匹配的。在此期间，参与者进行了一个发音抑制任务，干扰维护的口头编码的材料或随机数生成（RNG）任务，干扰执行资源。结果表明，性能的成像任务相比，知觉任务，被严重干扰的RNG任务，而这两个记忆任务的性能没有被干扰的抑制任务。这表明，维持一个视觉构建的形象，这不涉及言语处理，是一个功能，需要执行资源。
The present study examines whether the storage of a visually-constructed image requires executive resources. Experiment 1 was conducted to determine how long a visually-constructed pattern (imaging task) could be stored without sufficient rehearsal at 1 s, 6 s, and 11 s intervals. The results indicate that memory performance was significantly disrupted at the 11 s interval. Using this interval, memory performances for the imaging task and a perceptual task (requiring the temporary storage of a perceived pattern) were compared in Experiment 2. The two memory tasks were matched in terms of their degree of difficulty. During the interval, participants performed either an articulatory suppression task that interferes with the maintenance of verbally-coded materials or a random number generation (RNG) task that interferes with executive resources. The results indicate that performance for the imaging task, compared to the perceptual task, was severely disrupted by the RNG task, while performance of both memory tasks was not disrupted by the suppression task. This suggests that maintenance of a visually-constructed image, which does not involve verbal processing, is a function that requires executive resources.
