Recent studies have shown the importance of integrating multisensory information in the body representation for constituting self-consciousness. However, one idea that has received only scant attention is that our body representation is also constituted by knowledge of bodily visual characteristics (i.e. 'what I look like'). Here in two experiments we used a full body crossmodal congruency task in which visual distractors were presented on a photograph of the participant, another person, who was either familiar or unfamiliar, or an object. Results revealed that during the 'self-condition' CCEs were enhanced compared to the 'other condition'. The CCE was similar for unfamiliar and familiar others. CCEs for the object condition were significantly smaller. The results show that presentation of an irrelevant image of a body affects multimodal processing and that the effect is enhanced when that image is of the self. The results hold intriguing implications for body representation in social situations.
最近的研究表明，在构成自我意识时，将多感觉信息整合到身体表现中非常重要。然而，一个很少受到关注的观点是，我们的身体表现也由身体视觉特征的知识构成（即“我看起来的样子”）。在这里，我们在两个实验中使用了全身跨模态一致性任务，其中视觉干扰物呈现在参与者、熟悉或不熟悉的另一个人或物体的照片上。结果表明，在“自我条件”下，与“他人条件”相比，CCE 得到了增强。不熟悉和熟悉的他人的 CCE 相似。物体条件下的 CCE 明显较小。结果表明，呈现无关的身体图像会影响多模态处理，并且当该图像是自我时，效果会增强。这些结果对社会情境中的身体表现具有有趣的启示。
