蛙[蛙pipiens]在猎物样刺激抢购的偏好与真实的对象的大小，而不是其对向视角时，对象小于15厘米的距离。对于更远的猎物，视角线索似乎决定猎物的选择。使用第二次测试，涉及的歧视的光圈宽度，行为的指导下，无论青蛙的对象的距离，仅由视角。所谓的大小恒常性效应可能与摄食动机过程有关，而不代表人类受试者对真实的大小的知觉判断类型。
The preference of frogs [Rana pipiens] for snapping at prey-like stimuli was related to real object size rather than to its subtended visual angle when objects were less than 15 cm distant. For more distant prey, the visual angle cue seemed to determine prey choice. Using a 2nd test, involving a discrimination of aperture width, behavior was guided by visual angle alone regardless of the frog to object distance. The so-called size-constancy effect may be related to feeding motivation processes, and not represent the type of perceptual judgement of real size found with human subjects.
