在动态随机点显示中，要求猪和人区分相干运动和随机运动。相干性和速度阈值确定这两个物种，这两个阈值被发现是大大高于鸽子比人类。结果进行了讨论，在哺乳动物和鸟类的运动处理的差异。这表明鸽子的运动敏感性较差可以归因于较差的时空运动整合。
Pigeons and humans were required to discriminate coherent from random motion in dynamic random dot displays. Coherence and velocity thresholds were determined for both species, and both thresholds were found to be substantially higher for pigeons than for humans. The results are discussed with reference to differences in motion processing in mammals and birds. It is suggested that the inferior motion sensitivity of pigeons can be attributed to poorer spatiotemporal motion integration.
