目的：本研究旨在探討音樂專家之動態觸覺敏感度 (haptic sensitivity) 與敏銳度 (haptic acuity) 與其不同面向動作能力之相關性。方法：招募各22位音樂專家與無音樂經驗者執行兩個動態觸覺任務、Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Long Form (BOT-2-LF) 及Movement Assessment Battery for Children Second Edition (MABC-2) 動作能力測驗。動態觸覺的第一個任務為動態觸覺偵測任務 (haptic detection task)，以慣用手食指來回觸摸方塊（由左至右），判斷是否該個方塊有弧度，紀錄動態觸覺偵測閾值 (haptic detection thresholds)；第二任務為動態觸覺辨識任務 (haptic discrimination task)，同樣的觸摸方式，每次測驗時要判別2個方塊中哪一個方塊有較高的弧度，紀錄動態觸覺辨識閾值 (haptic discrimination thresholds)。結果：在動態觸覺敏感度上，音樂專家之動態觸覺偵測閾值顯著低於無音樂經驗者 (p = .049)。在動態觸覺敏銳度上，動態觸覺辨識閾值兩組間則無顯著差異 (p > .05)。另外，動態觸覺偵測閾值與BOT-2手部協調相關性 (r = -.58，p = .000)。結論：本研究證實音樂專家之動態觸覺敏感度較無音樂經驗者佳。此外，有較佳的動態觸覺成年人，亦有較高程度的手部協調動作能力。

Purpose: The purpose of this study was to investigate the relationship between haptic perception and different domains of motor skills in musicians. Method: We recruited 22 musicians and 22 control participants. All participants performed two haptic perception tasks and two standardized motor assessments: Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Long Form (BOT-2-LF) and Movement Assessment Battery for Children Second Edition (MABC-2). The first haptic is the haptic detection task. Participants touched a set of curvature blocks with the index finger of their dominant hand back and forth, and indicated which block was more curved. The second task is the haptic discrimination task. With the same exploratory procedure, participants determined which of the two blocks has the higher curvature. Haptic detection thresholds and haptic discrimination thresholds were obtained to measure haptic sensitivity and haptic acuity. Result: The results of the study found that in terms of haptic sensitivity, the haptic detection thresholds of musicians were significantly lower than controls (p = .049). However, the haptic discrimination thresholds were not significantly different between the two groups (p > .05). In addition, haptic detection thresholds were correlated with BOT-2 manual coordination (r = -.58, p = .000). Conclusion: This study confirms that the haptic sensitivity of musicians is better than controls. In addition, adults with better haptic functions also have a higher level of manual coordination.
