报道了一种速度错觉，它类似于在亮度对比度的情况下获得的结果。当两个目标在具有速度梯度的较小移动点的背景下以相同的速度移动时，比其周围移动得更快的目标似乎比移动得比其直接周围慢的目标移动得更快。因此，目标的表观速度强烈依赖于它相对于周围环境的速度；我们用运动敏感细胞来解释这一点，运动敏感细胞具有中心-周围拮抗，类似于对亮度对比度的生理解释。
A velocity illusion is reported which is analogous to results obtained in the case of brightness contrast. When two targets move with the same velocity against a background of smaller moving dots which have a velocity gradient, the target which is moving faster than its immediate surround appears to move faster than the target which is moving slower than its immediate surround. Apparent velocity of a target therefore depends strongly on its velocity in relation to its immediate surround; we interpret this in terms of motion-sensitive cells which have center–surround antagonisms analogous to the physiological interpretation of brightness contrast.
