The accuracy and stability of bimanual multifrequency tapping under synchronizing to visual and auditory stimuli
作者 黃嘉君 (Chia-Chun Huang)楊梓楣 (Chih-Mei Yang)
中文摘要
多頻動作意指兩肢體以不同頻率做節奏性動作,過去研究發現雙手多頻動作準確性及穩定性會受到動作頻率、同步之訊號、慣用手、及雙手頻率比等因素影響,進而改變其動作表現類型(正確表現、轉移表現、與不穩定表現)。目的:在檢證不同訊號與慣用手對雙手多頻拍擊動作表現的影響。方法:本研究參與者為24名無特定音樂或舞蹈經驗之年輕成人,平均21.9±3.0歲,其被隨機分派至視聽同時、視覺、聽覺訊號同步等三組,進行16組不同頻率比之雙手多頻拍擊動作(分為雙手同時、慣用手較快、與非慣用手較快等三種頻率比),並分析雙手動作的節奏準確度及穩定性,進一步獲得正確、轉移、及不穩定表現之次數,再分別對三種表現類型進行3(訊號)X3(頻率比)混合設計二因子變異數分析,其中頻率比為重複量數。結果:沒有慣用手效應;視聽同時組之表現顯著優於視覺組。結論:(一)視聽同時訊號對雙手多頻拍擊動作之準確度與穩定性有增強效果;(二)表現雙手多頻拍擊動作時,慣用手較快或較慢,並不影響雙手多頻拍擊動作表現。The multifrequency movement means performing movement with two limbs moving at different frequency. It has been investigated that the accuracy and stability of bimanual multifrequency tapping was influenced by some factors, such as movement frequency, the stimulus to synchronized, the preferred hand, and the ratio of the frequency of two hands. Purpose: To investigate the influence of stimuli and preferred hand on bimanual multifrequency tapping. Methods: 24 young adults were served as participants who were unexperienced in specific music or dance. They were randomly assigned to 3 groups, in which participants were required to synchronize the taps to visual, auditory, or audio-visual synchronal stimuli and to perform bimanual multifrequency tapping in 16 frequency ratios. After analyzing the rhythmic accuracy and stability of the intertap interval, the number of types of behavior that were correct performance, transition performance, and unstable performance would be obtained. 3 (stimulus) ×3 (ratio form) mixed design 2-way ANOVA was used to analyze each type. Result: The results showed that there was no effect of preferred hand. On the other hand, the performance of audio-visual synchronal group was better than visual group. Conclusions: (a) The audio-visual synchronal stimulus would enhance the accuracy and stability of bimanual multifrequency tapping; (b) No matter the preferred hand or non-preferred hand was the fast hand, there was no effect on the performance of bimanual multifrequency tapping.
