知觉学习的几个范例表明，实践可以触发长期的，经验依赖的变化，在成人的视觉系统的人类。如图所示，在正常睡眠后，基本视觉辨别任务的表现有所改善。选择性中断快速眼动（REM）睡眠导致在一个可比较的睡眠间隔没有性能增益，虽然非REM慢波睡眠中断没有影响改善。另一方面，剥夺快速眼动睡眠对类似的，但以前学过的任务的表现没有不利影响。这些结果表明，在睡眠期间活跃的人类记忆巩固过程强烈依赖于REM睡眠。
Several paradigms of perceptual learning suggest that practice can trigger long-term, experience-dependent changes in the adult visual system of humans. As shown here, performance of a basic visual discrimination task improved after a normal night's sleep. Selective disruption of rapid eye movement (REM) sleep resulted in no performance gain during a comparable sleep interval, although non-REM slow-wave sleep disruption did not affect improvement. On the other hand, deprivation of REM sleep had no detrimental effects on the performance of a similar, but previously learned, task. These results indicate that a process of human memory consolidation, active during sleep, is strongly dependent on REM sleep.
