摘要：

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. (C) 1998 Elsevier Science B.V.
