通过训练，一个人辨别相似运动方向的能力会逐渐提高。一系列研究表明，这种改善（1）仅限于训练方向和其他类似方向，（2）至少持续几个月，（4）显示出明显的，但不是完全的，两只眼睛之间的转移，（5）主要限于场的刺激区域。此外，方向辨别的改进不会产生检测阈值的伴随变化。在所有的可能性中，方向辨别能力的大部分改善代表了视觉功能的变化，而不是非感觉过程的变化。
With training, an observer''s ability to discriminate similar directions of motion gradually improves. A series of studies reveals that this improvement, (1) is restricted to the trained direction and other, similar directions, (2) persists for at least several months, (4) shows appreciable, but not complete, transfer between the two eyes, and (5) is largely restricted to the stimulated region of the field. Moreover, the improvement in direction discrimination does not produce a concomitant change in detection thresholds. In all likelihood, most of the improvement in direction discrimination represents a change in visual function, rather than changes in nonsensory processes.
