Understanding how the human brain integrates features of perceived events calls for the examination of binding processes within and across different modalities and domains. Recent studies of feature-repetition effects have demonstrated interactions between shape, color, and location in the visual modality and between pitch, loudness, and location in the auditory modality: repeating one feature is beneficial if other features are also repeated, but detrimental if not. These partial-repetition costs suggest that co-occurring features are spontaneously bound into temporary event files. Here, we investigated whether these observations can be extended to features from different sensory modalities, combining visual and auditory features in Experiment 1 and auditory and tactile features in Experiment 2. The same types of interactions, as for unimodal feature combinations, were obtained including interactions between stimulus and response features. However, the size of the interactions varied with the particular combination of features, suggesting that the salience of features and the temporal overlap between feature-code activations plays a mediating role.
理解人类大脑如何整合感知事件的特征，需要研究不同模态和领域内以及跨模态和领域的绑定过程。最近关于特征重复效应的研究表明，在视觉模态中形状、颜色和位置之间以及在听觉模态中音高、响度和位置之间存在相互作用：如果其他特征也重复，重复一个特征是有益的，但如果不重复则是有害的。这些部分重复成本表明，同时出现的特征会自发地绑定到临时事件文件中。在这里，我们研究了这些观察结果是否可以扩展到来自不同感觉模态的特征，在实验1中结合视觉和听觉特征，在实验2中结合听觉和触觉特征。获得了与单模态特征组合相同类型的相互作用，包括刺激特征和反应特征之间的相互作用。然而，相互作用的大小随特征的特定组合而变化，这表明特征的显著性和特征代码激活之间的时间重叠起着中介作用。
