In 7 experiments we investigated cross-modal links for endogenous covert spatial orienting in hearing and vision. Participants judged the elevation (up vs. down) of auditory or visual targets regardless of their laterality or modality. When participants were informed that targets were more likely on 1 side, elevation judgments were faster on that side, even if the modality of the target was uncertain. When participants expected a target on a particular side in just 1 modality, corresponding shifts of covert attention also took place in the other modality, as evidenced by faster elevation judgments on that side. However, it was possible to "split" auditory and visual attention when targets in the 2 modalities were expected on constant but opposite sides throughout a block, although covert orienting effects were larger when targets were expected on the same side in both modalities. These results show that although endogenous covert attention does not operate exclusively within a supramodal system, there are strong spatial links between auditory and visual attention.
在7项实验中，我们研究了听觉和视觉中内源性隐蔽空间定向的跨模态联系。参与者判断听觉或视觉目标的高度（向上还是向下），而不考虑其位置偏向或模态。当参与者被告知目标更有可能出现在一侧时，即使目标的模态不确定，该侧的高度判断也会更快。当参与者仅在一种模态中预期特定一侧会出现目标时，另一种模态中也会发生相应的隐蔽注意力转移，这一侧的高度判断更快就证明了这一点。然而，当在整个实验块中预期两种模态的目标出现在固定但相反的两侧时，有可能“分开”听觉和视觉注意力，尽管当两种模态都预期目标出现在同一侧时，隐蔽定向效应更大。这些结果表明，虽然内源性隐蔽注意力并非仅在超模态系统内起作用，但听觉和视觉注意力之间存在很强的空间联系。
