以4只鸽子为实验对象，研究了不同的单眼深度线索对场景感知任务的影响。他们区分了计算机渲染场景中三个几何物体的连续深度顺序。这些物体的顺序由相对密度、遮挡和相对大小的图像线索的存在或不存在来指定。在第一阶段，鸽子学习任务是作为提示数量的直接函数。三种单目线索对辨别的作用相同。第二阶段确定了物体上的不同阴影提供了额外的判别线索。这些结果表明，鸽子的视觉系统对许多已知的人类使用的相同的单眼深度线索很敏感。考虑了图像处理的比较心理学的理论含义。
The contributions of different monocular depth cues to performance of a scene perception task were investigated in 4 pigeons. They discriminated the sequential depth ordering of three geometric objects in computer-rendered scenes. The orderings of these objects were specified by the combined presence or absence of the pictorial cues of relative density, occlusion, and relative size. In Phase 1, the pigeons learned the task as a direct function of the number of cues present. The three monocular cues contributed equally to the discrimination. Phase 2 established that differential shading on the objects provided an additional discriminative cue. These results suggest that the pigeon visual system is sensitive to many of the same monocular depth cues that are known to be used by humans. The theoretical implications for a comparative psychology of picture processing are considered.
