利用皮質聽覺誘發電位評估時間遮蔽效應

// Temporal Masking Assessed With Cortical Auditory Evoked Potentials

本研究探討先行聲音如何影響大腦皮層對音節/ba/的聽覺誘發電位｜以不同時間間隔的語音型噪音作為掩蔽聲，測量年輕成年人反應幅度和潛伏期變化｜結果顯示掩蔽聲均增加反應潛伏期並減弱幅度，且影響不隨間隔時間恢復，挑戰傳統前向掩蔽模型的假設。

// This study examined how preceding sounds affect cortical auditory evoked potentials to the syllable /ba/ and tested hypotheses about forward masking effects over varying time intervals. Using speech-shaped noise maskers at different gaps before /ba/, researchers measured changes in response amplitude and latency in young adults. Results showed that maskers increased response latency and reduced amplitude regardless of the timing gap, contradicting expectations of interval-dependent recovery. The findings suggest that sequential sounds influence cortical responses differently than traditional forward masking models predict.
