Pigeons were trained to discriminate apparent movement and real movement in visual displays showing horizontal movement. Generalization testing on the dimension of directional movement yielded gradients that sloped as movement changed from horizontal to vertical. Evidence of generalization between apparent movement and real movement was found in equivalent response rates to training displays of either type. Extremely low response rates to training displays pulsating but showing no movement eliminated flicker as the basis of the discrimination.
鸽子接受训练,以区分视觉显示中呈现水平运动的表观运动和真实运动。在方向运动维度上的泛化测试产生了随着运动从水平变为垂直而倾斜的梯度。在对两种类型的训练显示具有等效反应率的情况下,发现了表观运动和真实运动之间的泛化证据。对脉动但不显示运动的训练显示的极低反应率排除了闪烁作为辨别基础的可能性。
