中文摘要 視動協調能力在人類日常生活事件執行上扮演相當重要的角色,而手眼協調能力是從小時發展到成熟,然後隨著年齡增長則能力會逐漸變差。過去研究主要探討正常人在單一實驗場景中的表現,對於不同年齡層在不同手眼協調作業中的表現差異則較少著墨。本研究探討不同年齡層受試者在一維靜態、一維動態、二維靜態與二維迷宮場景等四種作業之手眼協調表現。結果發現在數字符號替代測驗表現佳的年輕受試者在這四種作業的反應時間、動作時間表現顯著比其他族群還要好,藉由軌跡變異性的分析,發現可用基本動作控制能力、最大速度以及次動作數量三個方式來評估其動作能力的表現。進一步從上述實驗結果中發現,約有20%的年輕人及老人在斜直角座標系有特殊的軌跡表現。因此,想了解給予視覺線索是否有助於動作表現。結果發現給予路徑提示的動作時間較短,並利用上述實驗結果推測可用最大速度及次動作數量評估動作表現,發現有路徑提示可顯著增加年輕人及老年人的最大速度,而有更多時間利用視覺訊息進行動作調整,使次動作數量顯著增加。本實驗發展新式多變數的視動協調作業彌補一般紙本測驗評估不足,可了解實際動作表現的特徵後給予適當訓練,且給予視覺線索發現可明顯改善動作表現。因此,未來可利用此方法應用在手眼訓練的相關訓練上。
英文摘要 Eye-hand coordination, such as grasping an object or writing, is importantly and frequently used in our daily life. Previous studies, which emphasize on static condition in multiple dimensions, have indicated an age-dependent change existing in numerous visuomotor performance. However, age-dependent alteration in static and dynamic tasks remains largely unknown. In this study, two static tasks in 1D and 2D space and one dynamic task in 1D space were carried out in three age groups, i.e., preschool children, college students and elders. And we found that participants who have high score of digit symbol substitution test (DSST), related to visuomotor processing ability, performed better reaction time (RT) and movement time (MT). In general, college students showed best performance in terms of accuracy, reaction time (RT), movement time (MT), trajectory performance, peak velocity, and time to peak velocity in all tasks. In the analysis of trajectory, college student performed smoother pathway and the endpoints are more convergent. According to the result of trajectory variability, we thought visuomotor ability could be assessed through peak velocity (PV), time to peak velocity (time to PV), and the amount of submovement. And we have another task is to give additional visual cue to know whether the cue would benefit the trajectory performance. The results show that PV and the amount of submovement significantly increased, and both time to PV and MT decreased. Our findings indicate that age affects the visuomotor performance of both static and dynamic tasks in different ways. And giving additional visual cue may improve the motor performance.
