如何（不）研究聽覺皮層中的偏差敏感性與預測編碼

// How (not) to study deviance sensitivity and predictive coding in auditory cortex

本研究探討大腦對罕見聲音（偏差音）的反應，與感官環境及偏差敏感性的關聯｜發現常用比較方法（偏差音與控制反應）無法準確區分偏差敏感與適應效應｜部分適應模型可模擬偏差音反應，無需預測誤差機制｜結論強調需更嚴謹的機制建模與複雜實驗設計，方能有效驗證偏差敏感性。

// This study examines how brain responses to rare sounds (deviants) in auditory oddball sequences relate to sensory context and deviance sensitivity. Using auditory cortical models, the authors show that common comparison methods (deviant versus control responses) cannot reliably distinguish true deviance sensitivity from adaptation effects. They find that some adaptation models can mimic deviant responses without involving prediction error mechanisms. The research concludes that proving deviance sensitivity requires more rigorous mechanistic modeling and complex experimental designs beyond simple response comparisons.
