Recent studies of perceptual learning have explored and commented on variation in learning trajectories. Although several factors have been suggested to account for this variation, thus far the idea that humans vary in their perceptual learning capacities has received scant attention. In the present experiment, we aimed at providing a detailed picture of the variation in this capacity by investigating the perceptual learning trajectories of a considerable number of participants. The learning process was studied using the paradigm of length perception by dynamic touch. The results showed that there are substantial individual differences in the way perceivers respond to feedback. Indeed, after feedback, the participants' perceptual performances diverged. We conclude that humans vary in their perceptual learning capacities. The implications of this finding for recent discussions on variation in perception are explored.

学习通过动态接触感知长度的个体差异：感知学习能力差异的证据。

知觉学习的最新研究已经探索并评论了学习轨迹的变化。尽管已经提出了几种因素来解释这种变化，但是到目前为止，人们对感知学习能力的变化看法还很少受到关注。在本实验中，我们旨在通过调查大量参与者的知觉学习轨迹来提供这种能力变化的详细情况。使用通过动态触摸的长度感知范式来研究学习过程。结果表明，感知者对反馈的反应方式存在很大的个体差异。确实，在反馈之后，参与者的知觉表现有所不同。我们得出结论，人类的感知学习能力各不相同。
