摘要: 感觉主导效应是大脑面临多种感觉通道信息时, 优先加工某种感觉通道信息的现象。认知加工水平假说认为感觉主导效应的产生是由于不同认知加工水平所决定, 即早期知觉加工水平表现为视觉主导, 晚期反应加工水平表现为听觉主导。然而, 现有的研究并未关注认知加工水平中处于早期和晚期之间的中间加工水平如何影响感觉主导效应。研究操纵了位于中间加工水平的客体类别差异, 采用2-1 mapping (映射)范式通过3个实验考察介于早期知觉和晚期反应水平之间的客体类别表征如何影响跨通道冲突感觉主导效应。实验1结果发现, 客体类别差异能够调节反应水平的感觉主导效应。类别差异小时, 表现为视觉主导; 类别差异大时, 表现为听觉主导。实验2结果说明此效应的产生与视觉刺激不同加工深度无关, 证实了此效应的产生特异于视觉通道。实验3通过经颅直流电刺激技术抑制类别加工脑区, 即左侧颞前叶。结果发现, 反应水平的听觉主导效应消失。研究表明, 认知加工水平中的客体类别表征这一中间加工水平对感觉主导效应产生了调节, 完善了认知加工水平假说对于跨通道冲突感觉主导效应的解释。

Abstract:

Sensory dominance is a phenomenon in which the brain selectively processes specific sensory information when presented with multisensory inputs, thereby enhancing human perception of external stimuli. Previous studies have discussed sensory dominance at perceptual and response levels. However, how the intermediate processing level between perceptual and response levels affects sensory dominance remains unknown. Therefore, the present study adopted the cross-modal 2-1 mapping paradigm, and object categories were manipulated through three studies to investigate the role of the intermediate processing level on sensory dominance in a cross-modal conflict.

In this paradigm, based on key mapping, cognitive processing levels can be defined into the preresponse level (including perceptual and semantic levels) and the response level. The difference between the audiovisual incongruent condition and the audiovisual congruent condition is called the conflict effect, and sensory dominance can be obtained by comparing the conflict effect of attention to vision and auditory. Experiment 1 manipulated the degree of difference in object categories to explore its impact on sensory dominance. Experiments 1a−1c involved animal objects (small differences), tool objects (moderate differences), and animal and musical instrument objects (large differences). A total of 30 participants were recruited for each experiment. Visual pictures reached perceptual representation early, whereas auditory sounds reached semantic representation early. Therefore, Experiment 2 (34 participants) changed visual pictures into visual words on the basis of Experiment 1c to explore the effects of the visual presentation way of object categories on sensory dominance. In Experiment 3 (20 participants), transcranial direct current stimulation (tDCS) was used on the left anterior temporal lobe, an important brain region responsible for processing object categories to study casually the effects of object category on the sensory dominance of the response level further.

The results of Experiment 1 showed that, regardless of the difference in object categories, the conflict effect of attention to auditory at the preresponse level was significantly greater than that of attention to vision, that is, visual dominance. However, visual dominance at the response level appeared when the object category difference was small (Experiment 1a). Moreover, no sensory dominance was observed when the object category difference was moderate (Experiment 1b), and auditory dominance appeared when the object category difference was large (Experiment 1c). The results of Experiment 2 and Experiment 1c were consistent, that is, auditory dominance, indicating that this behavior pattern was not affected by the bottom-up visual presentation way. The results of Experiment 3 showed that under the cathodal tDCS condition, the preresponse level still showed visual dominance. However, the response level no longer showed sensory dominance. This result showed the effects of object categories on the sensory dominance of the response level from the causal level.

The mechanism of sensory dominance is still under investigation. The present study was the first to find that object categories affected the sensory dominance of the response level. From the perspective of cognitive processing level, the intermediate processing level played a regulating role in the sensory dominance of the response level. This finding can enrich the explanatory theory of sensory dominance and can provide a new perspective for the study of sensory dominance in a cross-modal conflict.

Key words: object categories, visual dominance, auditory dominance, preresponse level, response level
