对于空间注意力在个体感官模式中的作用，特别是视觉和听觉方面的作用，现在已经有了很大的了解。然而，以前很少有关于注意力可能的跨模态联系的研究。在这里，我们回顾了我们自己关于这一主题的实验的最新发现，这些发现揭示了模式之间广泛的空间联系。在触觉、听觉或视觉中呈现的不相关但突出的事件，可以在其他模态中吸引隐蔽的空间注意（只有一个例外，当眼跳被阻止时，视觉事件不会吸引听觉注意）。通过在一个模态相对于另一个模态中移动受体，可以检查这些跨模态相互作用的空间坐标。例如，当一只手被放在一个新的位置时，对它的刺激现在会将视觉注意力吸引到相应的不同位置，尽管注意力的某些方面不会以这种方式在空间上重新映射，跨模式联系在注意力的自愿转移中也很明显。当一个人强烈期望某一模态的目标（如听音）出现在某个特定位置时，他们对该位置的判断不仅会对预期的模态有所改善，而且对其他模态（如视觉）也会有所改善，即使后一模态的事件更有可能出现在其他地方。最后，我们的一些实验表明，来自不同感官模式的信息可能会被整合到一起，从而产生多模态的内部空间表征，从而引导注意力。在某些情况下，这种预先注意的跨模态整合可以产生有益的错觉，从而提高复杂场景中选择性注意的效率。
A great deal is now known about the effects of spatial attention within individual sensory modalities, especially for vision and audition. However, there has been little previous study of possible cross-modal links in attention. Here, we review recent findings from our own experiments on this topic, which reveal extensive spatial links between the modalities. An irrelevant but salient event presented within touch, audition, or vision, can attract covert spatial attention in the other modalities (with the one exception that visual events do not attract auditory attention when saccades are prevented). By shifting receptors in one modality relative to another, the spatial coordinates of these cross-modal interactions can be examined. For instance, when a hand is placed in a new position, stimulation of it now draws visual attention to a correspondingly different location, although some aspects of attention do not spatially remap in this way Crossmodal links are also evident in voluntary shifts of attention. When a person strongly expects a target in one modality (e.g. audition) to appear in a particular location, their judgements improve at that location not only for the expected modality but also for other modalities (e.g. vision), even if events in the latter modality are somewhat more likely elsewhere. Finally some of our experiments suggest that information from different sensory modalities may be integrated preattentively, to produce the multimodal internal spatial representations in which attention can be directed. Such preattentive cross-modal integration can, in some cases, produce helpful illusions that increase the efficiency of selective attention in complex scenes.
