睡眠依賴性鞏固對語音知覺學習的差異性影響：系統性綜述

// The Differential Impact of Sleep-Dependent Consolidation in Speech Perceptual Learning: A Systematic Review

系統性回顧30項實證（1,646人），依PRISMA｜睡眠穩定脆弱語音記憶、阻止清醒衰減；增強與泛化具條件性：增強受學習者能力影響，泛化需訓練變異｜結論：睡眠為選擇性過濾器，優先鞏固弱編碼記憶，僅對良好編碼重組，分層框架具語言訓練應用價值

// This systematic review aimed to clarify how sleep consolidates speech-sound learning by qualitatively synthesizing 30 empirical studies (1,646 participants) following PRISMA guidelines. Sleep reliably stabilizes fragile speech-sound traces against wake-dependent decay, whereas enhancement and generalization appear only conditionally. Enhancement was mainly modulated by learner aptitude and generalization required sufficient training variability; null results were linked to poor encoding fidelity or high computational demands, implying resource-limited consolidation. The authors conclude sleep acts as a selective filter that prioritizes stabilization of weakly encoded traces and allows reorganization only for well-encoded representations, and they propose a hierarchical framework to explain these patterns.
