發展性語言障礙兒童對自然語言的皮質追蹤：一項腦電語音解碼研究

// Cortical tracking of natural speech by children with developmental language disorder (DLD): An EEG speech decoding investigation

本研究以腦電圖(EEG)檢測發展性語言障礙(DLD)兒童聽故事時的低頻皮質語音追蹤能力｜結果顯示DLD兒童在右側顳葉的delta頻段語音追蹤明顯減弱，但總體delta與theta頻段追蹤準確度無顯著差異｜階段振幅及相位耦合模式相似，支持語音時間取樣理論(TS理論)中受損區域有限的假設

// This study investigated low-frequency cortical speech tracking in children with developmental language disorder (DLD) using EEG during story listening. While overall delta and theta band tracking accuracy did not differ between DLD and control groups, children with DLD showed reduced delta-band speech tracking specifically in the right temporal cortex. Phase-amplitude and phase-phase coupling patterns were similar across groups. The findings suggest that in DLD, impairments in temporal sampling of speech are localized rather than widespread, supporting predictions of the TS theory.
