在视觉人脸识别中，特征信息和几何信息都是重要的。然而，关于触觉人脸识别的信息本质以及这些信息是否与视觉中的信息相同，我们知之甚少。在我们的实验中，我们发现模态内比跨模态人脸识别性能更好，这表明人脸表征在很大程度上是特定于每种模态的。此外，这种成本在crossmodal性能被认为是独立的探索程序的差异，在编码过程中的方式。我们发现，当面部特征的视觉信息被保留时，跨通道面部感知是最有效的，这表明视觉信息是跨通道共享的。我们的研究结果表明，面部信息处理在视觉和触觉以类似的方式，但编码的信息的性质的质的差异是有效的模态内相对于跨模态识别。(c)2006爱思唯尔有限公司保留所有权利。
It is well documented that both featural and configural information are important in visual face recognition. Less is known, however, about the nature of the information underlying haptic face recognition and whether or not this information is the same as in vision. In our experiments we found better within modal than crossmodal face recognition performance suggesting that face representations are largely specific to each modality. Moreover, this cost in crossmodal performance was found to be independent of differences in exploratory procedures across the modalities during encoding. We found that crossmodal face perception was most efficient when configural information of the facial features was preserved suggesting that configural information is shared across modalities. Our findings suggest that face information is processed in a similar manner across vision and touch but that qualitative differences in the nature of the information encoded underlies efficient within modal relative to crossmodal recognition.
