本研究目的主要為瞭解在一般視覺任務的情況下,一、任務複雜度對於視覺搜尋能力的影響,二、桌球運動員與非運動員其空間視覺搜尋能力對於不同複雜度的視覺任務是否與具有差異存在。本研究方法:受試者為6 名臺灣優秀桌球選手與6 名無規律運動習慣的大專學生。研究設計讓受試者進行不同複雜度A 與B之二維視覺迷宮測驗,並利用SMI RED 眼動儀記錄眼球動作表現。探討眼動因子為:完成迷宮總時間、眼動在AOI 區域內時間占迷宮總完成時間比例、AOI 凝視時間占總完成迷宮之凝視時間比例、跳視頻率、跳視總計幅度。本研究結果顯示:一、較複雜之視覺迷宮B 中,無論是桌球運動員組或非運動員組,皆需要投入較多注意力來完成任務,完成迷宮總時間、眼動在AOI 區域內時間占迷宮總完成時間比例、AOI 凝視時間占總完成迷宮之凝視時間比例、跳視總計幅度,四個因子皆達到統計上顯著差異。二、較複雜之視覺迷宮B 中,運動員的跳視頻率顯著高於非運動員,而其跳視總計幅度之差異亦趨近於統計上顯著。本研究結論:桌球運動員相較於非運動員在不熟悉空間搜尋時,相對具有較優勢視覺注意力;此外推測需注視快速移動物體的活動,如桌球、羽球可能對視覺注意力與搜尋能力有正面提升的功效。
The purpose of this study was to investigate the visuomotor performance and visual attention processing between table tennis athletes and non-athletes. Six table tennis athletes and six normal college students were participated in this study. A SMI RED eye tracker was employed to record the visuomotor performance of subjects in two-dimensional visual maze tests with different complexity. Five visuomotor factors, including End Time (ms), AOI Net Dwell Time (%), AOI Fixation Time (%), Saccade Frequency (count/s) and Saccade Amplitude Total (°) were measured. The statistic results indicated that: 1. Regardless of attention, athletes and non-athletes groups were heightened in response to visual maze B test with more complexity. There are statically significant results in four visuomotor factors, such as, End Time, AOI Net Dwell Time, AOI Fixation Time and Saccade Amplitude Total. 2. Significant differences between two groups in Saccade Frequency related to visual maze B test were observed. The Saccade Amplitude Total was approached statistical significances. In conclusion, table tennis athletes showed a better visual attention than non-athletes in visual searching in unfamiliar space. In addition, the visual attention might be improved by table tennis training.
