两个实验研究了视频相干性对鸽子使用去/不去程序的相对运动的歧视的影响。猪笼草被训练来区分视频刺激，其中相机的视角是“围绕”还是“穿过”2个接近的物体的内部开口。实验1使用组内设计，实验2使用组间设计来研究以连贯平滑的向前顺序与随机扰乱的顺序对这些视频进行排序如何影响学习。在相干序列中，辨别学习明显更快。有人建议，鸽子的视觉系统整合三维运动信号跨越空间和时间，以产生一个稳定的，基于对象的感知世界。
Two experiments examined the effects of video coherence on the discrimination of relative motion by pigeons using a go/no-go procedure. Pigeons were trained to discriminate video stimuli in which the camera's perspective went either "around" or "through" the interior opening of 2 approaching objects. Experiment 1 used a within-groups design and Experiment 2 used a between-groups design to examine how sequencing these videos in a coherent smooth forward order versus a randomly scrambled order influenced learning. Discrimination learning was significantly faster with the coherent sequences. It is suggested that the pigeon visual system integrates 3-dimensional motion signals across space and time to produce a stable, object-based, perceptual world.
