Human perception thresholds can improve through learning. Here we report findings challenging the fundamental 'practice makes perfect' basis of procedural learning theory, showing that brief reactivations of encoded visual memories are sufficient to improve perceptual discrimination thresholds. Learning was comparable to standard practice-induced learning and was not due to short training per se, nor to an epiphenomenon of primed retrieval enhancement. The results demonstrate that basic perceptual functions can be substantially improved by memory reactivation, supporting a new account of perceptual learning dynamics.

记忆重新激活可改善视觉感受。

人类的感知阈值可以通过学习来提高。在这里，我们报告了挑战性的过程学习理论的基本“实践使完美”基础的发现，表明对编码的视觉记忆的短暂重新激活足以提高知觉辨别阈值。学习可与标准实践诱导的学习相提并论，并不是由于本身的培训时间短，也不是由于增强了检索能力的现象。结果表明，基本的感知功能可以通过记忆重新激活得到实质性改善，从而支持了感知学习动态的新解释。
