Two experiments examined pigeons' discrimination of directional movement using pictorial images shown on computer monitors. Stimuli consisted of the movement of a bird against a stationary background or the movement of the background behind a stationary bird. In Experiment 1, pigeons were trained to discriminate either leftward or rightward motion of either the bird or the background from stationary frames drawn from the same movies. The background-discrimination group acquired the discrimination faster than the bird-discrimination group. In Experiment 2, transfer of the discrimination from the task of Experiment 1 to a discrimination between motion directions was examined. Most of the pigeons learned this discrimination rapidly, whereas in a pilot study in which direction discrimination was trained without previous static/movement discrimination, learning was poor. It appears that an experimental history of movement against stationary discrimination promoted the pigeons' learning of the directional motion discrimination.
两项实验研究了鸽子对计算机显示器上显示的图像中方向运动的辨别能力。刺激物包括一只鸟在静止背景前的运动，或静止鸟后方背景的运动。在实验1中，鸽子被训练从同一部电影中抽取的静止画面中辨别鸟或背景的向左或向右运动。背景辨别组比鸟辨别组更快地学会了辨别。在实验2中，研究了从实验1的任务到运动方向辨别的辨别转移。大多数鸽子很快学会了这种辨别，而在一项初步研究中，在没有先前的静态/运动辨别训练的情况下进行方向辨别训练，学习效果很差。似乎与静止辨别相对的运动的实验经历促进了鸽子对方向运动辨别的学习。
