We take issue with theories about the direction specificity in perceptual learning of motion discrimination. Trials of motion discrimination in two opposite directions were interleaved in uneven proportions (2:1). Human subjects improved faster in the direction with less frequent trials, indicating that learning transferred from the more frequent to the less frequent direction.
我们对运动辨别感知学习中方向特异性的理论提出质疑。在两个相反方向上进行的运动辨别试验以不均衡的比例（2:1）交替进行。人类受试者在试验次数较少的方向上提高得更快，这表明学习从试验次数较多的方向转移到了试验次数较少的方向。
