在这篇文章中,我们回顾了对狗(犬熟悉)的眼动追踪研究,有三个目标;我们强调了使用眼动追踪在犬的感知和认知领域取得的成就,然后讨论在人类心理物理学中开发的技术的应用中出现的挑战,最后提出了狗眼追踪研究的新途径。对于第一个目标,我们目前的研究调查了狗对人类的感知,主要是面孔,还有手,gaze,情感,通信信号,以目标为导向的运动,和社会互动,以及对代表可能和不可能的物理过程和动画线索的动画的感知。然后,我们讨论目前对狗进行眼动追踪的挑战,比如可疑的图片-物体对等,广泛的培训,小样本量,困难的校准,和人工刺激和设置。我们建议对这些问题进行可能的改进和解决方案,以实现更好的刺激和数据质量。最后,我们建议使用动态刺激,瞳孔测量,到达时间分析,移动眼动追踪,并与行为和神经影像学方法相结合,以进一步推进犬的研究,并在这一高度动态的比较认知分支中开辟新的科学领域。
In this article, we review eye-tracking studies with dogs (Canis familiaris) with a threefold goal; we highlight the achievements in the field of canine perception and cognition using eye tracking, then discuss the challenges that arise in the application of a technology that has been developed in human psychophysics, and finally propose new avenues in dog eye-tracking research. For the first goal, we present studies that investigated dogs\' perception of humans, mainly faces, but also hands, gaze, emotions, communicative signals, goal-directed movements, and social interactions, as well as the perception of animations representing possible and impossible physical processes and animacy cues. We then discuss the present challenges of eye tracking with dogs, like doubtful picture-object equivalence, extensive training, small sample sizes, difficult calibration, and artificial stimuli and settings. We suggest possible improvements and solutions for these problems in order to achieve better stimulus and data quality. Finally, we propose the use of dynamic stimuli, pupillometry, arrival time analyses, mobile eye tracking, and combinations with behavioral and neuroimaging methods to further advance canine research and open up new scientific fields in this highly dynamic branch of comparative cognition.
