Human faces elicit faster saccades than objects or animals, resonating with the great importance of faces for our species. The underlying mechanisms are largely unclear. Here, we test two hypotheses based on previous findings. First, ultra-rapid saccades toward faces may not depend on the presence of the whole face, but the upper face region containing the eye region. Second, ultra-rapid saccades toward faces (and possibly face parts) may emerge from our extensive experience with this stimulus and thus extend to glasses and masks - artificial features frequently encountered as part of a face. To test these hypotheses, we asked 43 participants to complete a saccadic choice task, which contrasted images of whole, upper and lower faces, face masks, and glasses with car images. The resulting data confirmed ultra-rapid saccades for isolated upper face regions, but not for artificial facial features.
人脸比物体或动物更能引起快速眼动，这与脸对我们物种的重要性是一致的。其背后的机制在很大程度上还不清楚。在这里，我们根据之前的发现检验了两个假设。首先，朝向人脸的超快速眼动可能不依赖于整个脸部的存在，而是依赖于包含眼部区域的上部脸部区域。其次，朝向人脸（可能还有脸的部分）的超快速眼动可能源于我们对这种刺激的广泛经验，因此也延伸到了眼镜和面具——这是作为脸的一部分经常遇到的人为特征。为了检验这些假设，我们要求 43 名参与者完成一个眼跳选择任务，该任务对比了完整的、上部的和下部的脸、面罩和眼镜的图像与汽车的图像。结果数据证实了孤立的上部面部区域的超快速眼动，但对于人为的面部特征则不然。
