音樂專家之動態觸覺與不同面向的動作能力
Haptic Perception and Different Aspects of Motor Skills in Musicians
摘要
動態觸覺是體感覺系統中觸覺與本體感覺之統合，其定義為透過視覺遮蔽以手部的觸摸偵測物體表面及形狀等資訊。動態觸覺對動作發展及動作控制上扮演重要角色。先前研究指出規律從事音樂訓練者有較佳的本體感覺，然而，針對動態觸覺表現與動作能力之關聯性則尚未明確。本研究目的在探討吹管樂器音樂專家之動態觸覺敏感度與敏銳度與其不同面向動作能力之相關性。研究招募各22位音樂專家與無音樂經驗者執行兩個動態觸覺任務及Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Long Form（BOT-2-LF）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，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，記錄動態觸覺偵測閾值；第二任務為動態觸覺辨識任務，同樣的觸摸方式，每次測驗時要判別兩個方塊中哪一個方塊有較高的弧度，記錄動態觸覺辨識閾值。實驗結果發現，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。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。另外，動態觸覺偵測閾值與BOT-2手部協調相關性。本研究結論證實吹管樂器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。

Haptic perception, the integration of touch and proprioception of the somatosensory system, is defined as an individual's ability to detect objects' surface, shape, and size by actively touching them with the hands. Haptic perception plays an important role in motor development and motor control. Previous studies have indicated that regular musical training is associated with better haptic perception. However, the relationships between haptic and motor functions in musicians are unclear. The purpose of this study was to systematically investigate the relationship between haptic perception (i.e., haptic acuity and sensitivity) and motor skills of different aspects in young adults with and without musical experiences. This study recruited 22 musicians and 22 control participants. All participants performed two haptic perception tasks and a standardized motor assessment: Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Long Form (BOT-2-LF). For the haptic detection task, participants touched a set of curvature blocks with the index finger of their dominant hand and indicated which block was more curved. For the haptic discrimination task, participants determined which of the two blocks had the higher curvature. Haptic detection and discrimination thresholds were obtained to measure haptic sensitivity and acuity. The results revealed that in terms of haptic sensitivity, the haptic detection thresholds in musicians were significantly lower than in controls. Haptic discrimination thresholds were not significantly different between the two groups. Results from correlation analysis showed that haptic detection thresholds were significantly correlated with BOT-2 manual coordination among all participants. In conclusion, this study confirms that musicians have higher haptic sensitivity levels than did the controls. Furthermore, adults with higher levels of haptic sensitivity tend to show greater levels of manual coordination.
