返回抑制(IOR)是指在线索-靶子范式中，对出现在先前注意位置的靶子反应较慢。它在视觉或听觉通道方面已经得到了很大的探索。本研究考察了在特定通道选择性注意(实验1)和分离通道注意(实验2)条件下，视听目标的返回抑制比(IOR)与视觉目标返回抑制(IOR)的差异。我们采用了外源性空间线索范式，并操纵了目标的形态，包括视觉、听觉或视听形态。参与者被要求在视觉通道或视觉和听觉通道中检测目标，这些通道呈现在与之前的视觉外围线索相同(提示)或相反(未提示)的一侧。在实验1中，我们发现当参与者被要求选择性地聚焦于视觉通道时，视觉和视听目标的IOR是相似的。然而，在实验2中，当同时注意视觉和听觉通道时，视听目标的返回抑制比视觉目标的返回抑制要小。我们还观察到，与非线索位置相比，线索位置的多感官反应增强效应和种族模型不等性违反减少。这些结果首次提供了视听目标的IOR证据。此外，当注意到这两种模式时，视听目标的IOR会降低。探讨了外源性空间注意与视听整合之间的相互作用。
Inhibition of return (IOR) refers to the slower response to a target appearing at a previously attended location in a cue–target paradigm. It has been greatly explored in the visual or auditory modality. This study investigates differences between the IOR of audiovisual targets and the IOR of visual targets under conditions of modality-specific selective attention (Experiment 1) and divided-modalities attention (Experiment 2). We employed an exogenous spatial cueing paradigm and manipulated the modalities of targets, including visual, auditory, or audiovisual modalities. The participants were asked to detect targets in visual modality or both visual and auditory modalities, which were presented on the same (cued) or opposite (uncued) side as the preceding visual peripheral cues. In Experiment 1, we found the comparable IOR with visual and audiovisual targets when participants were asked to selectively focus on visual modality. In Experiment 2, however, there was a smaller magnitude of IOR with audiovisual targets as compared with visual targets when paying attention to both visual and auditory modalities. We also observed a reduced multisensory response enhancement effect and race model inequality violation at cued locations relative to uncued locations. These results provide the first evidence of the IOR with audiovisual targets. Furthermore, IOR with audiovisual targets decreases when paying attention to both modalities. The interaction between exogenous spatial attention and audiovisual integration is discussed.
