尽管对家犬的视觉交流进行了大量的研究，但它们的认知能力尚未通过眼动追踪来探索。本研究的目的是在排除社会线索和联想学习的条件下，使用无接触眼动跟踪来扩展狗的视觉认知知识。我们研究了狗是否会自发地看图片中的实际物体，并根据它们的新奇或分类信息内容区分图片。本研究追踪了六只家犬在呈现人脸、狗脸、玩具和字母字符的数字彩色图像时的眼动。我们发现，狗的注意力集中在图像的信息区域，没有任何特定的任务的预训练和他们的凝视行为取决于图像类别。与其他类别相比，狗更喜欢同种的面部图像，并且无论类别如何，对熟悉图像的注视时间都比对新刺激的注视时间长。狗对人类面孔和无生命物体的同类的吸引力可能反映了它们的自然兴趣，但需要进一步的研究来确定狗是否具有图片物体识别能力。非接触式眼动跟踪是一种很有前途的方法，用于更广泛地探索以前在行为研究中发现的狗的特殊社会认知技能的过程。
Despite intense research on the visual communication of domestic dogs, their cognitive capacities have not yet been explored by eye tracking. The aim of the current study was to expand knowledge on the visual cognition of dogs using contact-free eye movement tracking under conditions where social cueing and associative learning were ruled out. We examined whether dogs spontaneously look at actual objects within pictures and can differentiate between pictures according to their novelty or categorical information content. Eye movements of six domestic dogs were tracked during presentation of digital color images of human faces, dog faces, toys, and alphabetic characters. We found that dogs focused their attention on the informative regions of the images without any task-specific pre-training and their gazing behavior depended on the image category. Dogs preferred the facial images of conspecifics over other categories and fixated on a familiar image longer than on novel stimuli regardless of the category. Dogs’ attraction to conspecifics over human faces and inanimate objects might reflect their natural interest, but further studies are needed to establish whether dogs possess picture object recognition. Contact-free eye movement tracking is a promising method for the broader exploration of processes underlying special socio-cognitive skills in dogs previously found in behavioral studies.
