视觉错觉是由元素组成的物体，这些元素的排列方式会导致对物体物理属性的错误感知。视觉错觉用于研究人类和非人类动物的视觉感知，因为它们提供了对感知系统背后的心理和认知过程的洞察。在一组三个实验中，我们检查了狗是否能够学习关系辨别并感知穆勒-莱尔错觉。在实验 1 中，狗被训练使用触摸屏上的两种强制选择程序来区分线的长度。在学习了辨别能力后，狗对新范例的概括能力和能力阈值都受到了测试。在第二个实验中，狗接受了穆勒-莱尔错觉作为测试试验，同时还进行了控制总体刺激大小的额外测试试验。狗似乎察觉到了这种幻觉；然而，对照试验表明他们正在利用全局规模来解决该任务。实验 3 提出了经过修改的刺激，已知这些刺激可以增强其他物种对幻觉的感知。然而，狗的表现却保持不变。这些发现揭示了狗关系学习的证据。然而，他们未能感知到这种错觉强调了在检查这些范式时使用全套对照试验的重要性，并且表明视敏度可能在这种感知现象中发挥着至关重要的作用。
Visual illusions are objects that are made up of elements that are arranged in such a way as to result in erroneous perception of the objects’ physical properties. Visual illusions are used to study visual perception in humans and nonhuman animals, since they provide insight into the psychological and cognitive processes underlying the perceptual system. In a set of three experiments, we examined whether dogs were able to learn a relational discrimination and to perceive the Müller-Lyer illusion. In Experiment 1, dogs were trained to discriminate line lengths using a two-alternative forced choice procedure on a touchscreen. Upon learning the discrimination, dogs’ generalization to novel exemplars and the threshold of their abilities were tested. In the second experiment, dogs were presented with the Müller-Lyer illusion as test trials, alongside additional test trials that controlled for overall stimulus size. Dogs appeared to perceive the illusion; however, control trials revealed that they were using global size to solve the task. Experiment 3 presented modified stimuli that have been known to enhance perception of the illusion in other species. However, the dogs’ performance remained the same. These findings reveal evidence of relational learning in dogs. However, their failure to perceive the illusion emphasizes the importance of using a full array of control trials when examining these paradigms, and it suggests that visual acuity may play a crucial role in this perceptual phenomenon.
