概括能力是从具体的例子中提取经验并将其应用于新的例子的能力，是语言习得的重要组成部分。泛化不仅取决于在清醒期间对输入的暴露，而且还可以在睡眠期间离线改善。在这里，我们研究了在睡眠中有针对性的记忆再激活是否会影响语法概括。参与者通过互动学习程序逐渐掌握了人工语言的语法规则。然后，短语的语言（实验组）或刺激从一个无关的任务（控制组）被秘密呈现在午睡。与对照组的参与者相比，在睡眠中重新接触语言的参与者在语法概括方面表现出更大的进步。睡眠提示产生了偏差，不一定是纯粹的增益，这表明睡眠期间记忆重放的能力是有限的。我们的结论是，语法概括是有偏见的听觉线索在睡眠中，并通过扩展，睡眠可能会影响语法概括一般。(C)2015 Elsevier Inc.

Generalization-the ability to abstract regularities from specific examples and apply them to novel instances-is an essential component of language acquisition. Generalization not only depends on exposure to input during wake, but may also improve offline during sleep. Here we examined whether targeted memory reactivation during sleep can influence grammatical generalization. Participants gradually acquired the grammatical rules of an artificial language through an interactive learning procedure. Then, phrases from the language (experimental group) or stimuli from an unrelated task (control group) were covertly presented during an afternoon nap. Compared to control participants, participants re-exposed to the language during sleep showed larger gains in grammatical generalization. Sleep cues produced a bias, not necessarily a pure gain, suggesting that the capacity for memory replay during sleep is limited. We conclude that grammatical generalization was biased by auditory cueing during sleep, and by extension, that sleep likely influences grammatical generalization in general. (C) 2015 Elsevier Inc.
