青少年與年輕成人對音調及噪音之皮質聽覺誘發電位的成熟過程

// Maturation of Cortical Auditory Evoked Potentials in Response to Tones and Noise During Adolescence and Young Adulthood

本研究探討青少年至青年期大腦皮層聽覺誘發電位（CAEPs）對音調與噪音的發展｜CAEP的P1、N1、N2、P2波形在潛伏期與振幅上隨年齡變化，顯示皮層持續成熟｜噪音與音調CAEP反應差異能預測噪聲聲碼器語音理解，但無法預測背景噪音中語音理解，年齡為最強預測因子。研究揭示發展過程中不同受損語音感知涉及獨特神經機制。

// This study examined how cortical auditory evoked potentials (CAEPs) to tones and noise develop from adolescence to young adulthood and their relation to degraded speech perception. CAEP components (P1, N1, N2, P2) showed age-related changes in latency and amplitude, indicating continued cortical maturation. Differences in CAEP responses to noise versus tones predicted noise-vocoded speech perception but not speech in noise, with age being the strongest overall predictor. These findings suggest distinct neural mechanisms underlie perception of different degraded speech types during development.
