空间工作记忆可以保持来自视觉、听觉和触觉的表征，这些表征在这里被称为空间图像。本实验探讨了同时存在于工作记忆中的视觉和听觉的空间图像是否保留了模态特异性标签或非模态。观察者被呈现为在角度方向上变化的短序列的目标，在给定的序列中的目标是所有听觉的，所有视觉的，或两者的顺序混合物。在三分之二的审判中，其中一个地点是重复的，观察员在发现这种重复时必须尽快作出反应。辅助检测和定位任务证实，视觉和听觉目标的感知可比。在工作记忆任务中的反应延迟表现出小，但可靠的成本，在涉及听觉和视觉目标的顺序混合物的试验中的性能，与纯视觉或纯听觉的试验相比。这些赤字是统计学上可靠的试验上的匹配位置的方式从倒数第二个切换到最后的目标序列，表明切换成本。对于直接连续的对的切换成本意味着表示目标位置的空间图像保留了它们从中导出的视觉或听觉表示的特征。然而，没有可靠的证据表明，在匹配对中的混合模式的性能成本时，两个中的第二个没有立即跟随第一个，这表明，更持久的空间图像在工作记忆中可能是amodal。
Spatial working memory can maintain representations from vision, hearing, and touch, representations referred to here as spatial images. The present experiment addressed whether spatial images from vision and hearing that are simultaneously present within working memory retain modality-specific tags or are amodal. Observers were presented with short sequences of targets varying in angular direction, with the targets in a given sequence being all auditory, all visual, or a sequential mixture of the two. On two thirds of the trials, one of the locations was repeated, and observers had to respond as quickly as possible when detecting this repetition. Ancillary detection and localization tasks confirmed that the visual and auditory targets were perceptually comparable. Response latencies in the working memory task showed small but reliable costs in performance on trials involving a sequential mixture of auditory and visual targets, as compared with trials of pure vision or pure audition. These deficits were statistically reliable only for trials on which the modalities of the matching location switched from the penultimate to the final target in the sequence, indicating a switching cost. The switching cost for the pair in immediate succession means that the spatial images representing the target locations retain features of the visual or auditory representations from which they were derived. However, there was no reliable evidence of a performance cost for mixed modalities in the matching pair when the second of the two did not immediately follow the first, suggesting that more enduring spatial images in working memory may be amodal.
