尽管已有充分证据表明，由位置重复引起的空间抑制效应（即返回的空间抑制，或 IOR）以跨模态方式发生，但我们尚不知道非空间（例如，基于颜色的）重复引起的抑制是否也以跨模态方式发生。在本研究中，采用了一种关于基于颜色的重复的新颖的跨模式范例。在重复启动任务中，在启动项和目标项之间引入了一个中间中性线索，其语义身份与启动项和目标项都不同。启动项、中性提示和目标的模态可以是视觉的或听觉的，并且启动项和目标可以指代相同或不同的语义身份。通过采用这种范式，我们旨在回答两个问题：（1）跨模态基于语义的重复抑制发生的具体条件是什么？ （2）基于语义的重复抑制效应中的表征是超模态的还是特定模态的？我们的结果表明，基于语义的重复抑制仅当主要提示和中性提示来自相同的感觉模态时才会发生，并且无论目标模态是否被提示，也无论目标模态是听觉还是视觉，它都会发生。综上所述，我们的结果表明，跨模态非空间重复抑制的发生是有条件的，并且重复抑制所抑制的非空间表征是超模态的。
Although it has been well documented that the spatial inhibitory effect induced by repetition of location (i.e., spatial inhibition of return, or IOR) occurs cross-modally, we do not yet know whether nonspatial (e.g., color-based) repetition-induced inhibition occurs in a cross-modal fashion as well. In the present study, a novel cross-modal paradigm with regard to color-based repetition was adopted. An intervening neutral cue, whose semantic identity was different from those of both the prime and the target, was introduced between the prime and the target in a repetition-priming task. The modalities of the prime, the neutral cue, and the target could be either visual or auditory, and the prime and the target could refer either to the same or to different semantic identities. By adopting this paradigm, we aimed to answer two questions: (1) What are the specific conditions under which cross-modal semantic-based repetition inhibition occurs? (2) Are the representations inhibited in the semantic-based repetition inhibition effect supramodal or modality-specific? Our results suggested that semantic-based repetition inhibition occurs only when the prime and the neutral cue are from the same sensory modality, and it occurs irrespective of whether the modality of the target is cued and irrespective of whether the modality of the target is auditory or visual. Taken together, our results suggest that the occurrence of cross-modal nonspatial repetition inhibition is conditional and that the nonspatial representations inhibited by the repetition inhibition are supramodal.
