呈現順序對人工耳蝸使用者與正常聽力者音高排序敏感度的影響及其緩解方法

// Impact of Presentation Order on Pitch Ranking Sensitivity in Cochlear Implant Users and Normal-Hearing Listeners and Its Mitigation

本研究比較人工耳蝸（CI）使用者與正常聽力者的音高感知偏差｜發現雙方在單側音高排序任務中難以辨別音高，且判斷偏差受刺激順序影響｜結果顯示存在一種非對稱的情境依賴性偏差，與受試者對連續刺激的比較方式有關｜強調控制此偏差對準確評估人工耳蝸使用者的音高感知至關重要。

// This study examined pitch perception biases in cochlear implant (CI) users and normal-hearing (NH) listeners using unilateral pitch ranking tasks. Both groups showed similar difficulty discriminating pitch with biases influenced by the presentation order of electrode pairs or stimuli. Results suggest an asymmetric context-dependent bias affecting pitch judgments, linked to how subjects compare sequential stimuli. Controlling for these biases is crucial for reliable psychophysical assessment of pitch perception in CIs.
