睡眠已知可以增進記憶的固化作用。一個廣泛地假說認為這是因為新進的訊息在睡眠時經過了一些再激發的歷程。
先前研究指出經由一些特定的記憶步驟，能夠增進程序型記憶作業的學習。
作業表現會隨著訓練而改善，並且在沒有額外的複習之下，藉著學習後的睡眠繼續進步。
睡眠有助於程序型記憶的穩固、強化。然而，沒有研究指出如何在睡眠中再促進程序型記憶的穩固。在此，我們想探討在不同的睡眠階段，利用聽覺刺激重建學習環境，是否能在睡眠當中再促進程序型記憶的強化。
我們設計了兩實驗。行為實驗：此實驗目的在探討訓練過程中如何呈現聽覺刺激。此實驗有三組分別是(1)有敲打就有聽覺刺激、(2)正確敲打才有聽覺刺激與(3)固定節奏方式呈現。每組實驗皆有一次的控制組測試與一次實驗組測試。
此實驗結果發現各組訓練過程的表現並無顯著的差異。經過一晚睡眠，各組控制組後測的表現皆有顯著增進。但在實驗組後測的表現，只在組別ㄧ後測表現有顯著增進，其他兩組則無。
睡眠實驗：此實驗目的是利用行為實驗的訓練方式與在不同睡眠重建學習環境。此實驗有三組分別是(1)聽覺刺激呈現在訓練與慢波睡眠、(2)聽覺刺激呈現在訓練與快速眼動期與(3)聽覺刺激只呈現在快速眼動期。每組實驗皆有一次的控制組測試與一次實驗組測試。
此實驗結果發現，在組別二，實驗組後測的表現明顯好於控制組後測的表現，且實驗組的增進率也明顯好控制組的增進率。我們也發現在重建環境過程中，β活性有顯著的增強，且增強的百分比與兩次實驗增進率的差有一正相關。

Sleep facilitates memory consolidation. A widely held model assumes that this is because newly encoded memories undergo covert reactivation during sleep.
Learning of a procedural memory task is known to progress through a series of unique memory stages. Performance initially improves during training, and continues to improve, without further rehearsal, across subsequent periods of sleep.
The sleep is helpful for consolidating procedural memory. However, no study indicates how to promote more consolidation of procedural memory during sleep. Here, we investigate that whether reinstating that training context by auditory stimulus during different sleep stage can promote the memory consolidation.
We design two experiments. Behavior Experiment, the purpose of this experiment is to investigate that how to play the auditory stimulus during training. There are three groups in this experiment, (1) auditory stimulus in all tapping, (2) auditory stimulus in correctly tapping and (3) fixed-frequency auditory stimulus. Each group is two testing condition in which the auditory stimulus (Exp.) or vehicle (Ctrl.).
The result of this experiment is found that the performance of the training of Ctrl. and Exp. of three groups are no significant different between groups. After a night sleep, the performance of the retest of Ctrl. of three groups all show a significant improvement. The performance of the retest of Exp. of Group 1 only shows a significant improvement, and the other two groups are not.
Sleep Experiment, the purpose of this experiment is to use the training way of Behavior Experiment and reinstate that training context during different sleep stage. There are three groups in this experiment, (1) auditory stimulus is during training and SWS, (2) auditory stimulus is during training and REM, (3) auditory stimulus is only during REM. Each group is two testing condition in which the auditory stimulus (Exp.) or vehicle (Ctrl.).
The result of this experiment is found that, Group 2, the performance of the retest of Exp. was better than the performance of the retest of Ctrl., and the improvement of Exp. was also better than the improvement of Ctrl. we also found that the beta power activity during reinstating that training context shows a significant enhance and the enhanced percentage show a positive correlation with the difference between improvement of Ctrl. and Exp..
