To respond to multisensory information, inputs from different sensory modalities must be processed and combined. Recently, overt spatial attention was shown to be a crucial factor modulating the processing of irrelevant audiovisual multisensory stimuli. Here, we investigate the processing of task-irrelevant visuotactile features in a multisensory flanker interference task incorporating visuotactile target and distractor stimuli. The congruency between the target and distractor features was varied orthogonally. Across three experiments, overt spatial attention and the spatial separation between the distractor and the target were varied systematically. When fixating the distractor, the processing of the visual and tactile distractor features was not independent. Manipulating overt spatial attention as well as the spatial separation between the target and distractor impacted multisensory distractor processing. These results are consistent with those approaches emphasizing the role of attention in multisensory processing specifically in relation to the cognitive load or selection difficulty of the task situation.

为了响应多感官信息，必须处理和组合来自不同感觉模态的输入。最近，明显的空间注意力被证明是调节无关视听多感官刺激处理的关键因素。在这里，我们在包含视触靶和干扰刺激的多感官侧抑制任务中研究了无关视触特征的处理。目标和干扰特征之间的一致性是正交变化的。在三个实验中，我们系统地改变了明显的空间注意力和干扰与目标之间的空间分离。当注视干扰时，视觉和触觉干扰特征的处理不是独立的。操纵明显的空间注意力以及目标和干扰之间的空间分离会影响多感官干扰处理。这些结果与那些强调注意在多感官处理中的作用的方法一致，特别是与任务情况的认知负荷或选择难度有关。
