對聽覺誤差的適應調節其感知

// Adaptation to Auditory Errors Modulates Perception of the Errors

30名成人於四種條件說CVC詞，量測元音前100毫秒的運動適應｜所有條件有適應；共振峰位移（元音頻率）比固定回饋引發更大適應，感知誤差小；適應與感知誤差在位移與突發固定回饋相關，漸進固定回饋不相關；顯示二者為情境依賴的感覺—動作整合，利於矯治。

// They tested whether speech motor adaptation changes perception when auditory feedback is fixed (formant-clamp) or shifted, introduced suddenly or gradually. Thirty adults produced CVC words in four conditions and reported perceived vowel feedback with a continuous slider while motor adaptation was measured in the first 100 ms of the vowel. All conditions produced adaptation, but formant-shifts caused larger adaptation and smaller perceived error than formant-clamps; adaptation correlated with perceived error in both shift conditions and the sudden clamp, but not in the gradual clamp. This shows perception and speech motor adaptation are tightly linked but depend on perturbation type, implying context-dependent sensorimotor integration rather than a fixed perception–action mapping.
