摘要
用EyeLinkII型眼动仪为实验设备 ,以汉字与双眼形成的视角为自变量 ,研究了视角对高频汉字识别的影响特点。本实验中的视角分为 7个水平 :2°、4°、7°、1 0°、1 3°、1 6°、1 9° ,通过自编程序 ,计算出固定距离条件中不同视角下汉字的大小 ,呈现在计算机屏幕上 ,要求被试发声识别汉字。通过对反应时、注视时间、注视次数、眼跳时间、眼跳次数、眨眼时间、眨眼次数的分析。结果发现 :不同视角条件下的反应时总体差异不显著 ,反应时随视角的变化曲线为抛物线 ,开口向上 ;汉字识别的最适宜视角为 1 0°～ 1 1°。
The effect of visual angle on the recognition of Chinese characters with high frequency scores was studied with the EyeLink Ⅱ eyemovement instrument. The Chinese characters were selected as based on their high frequency and left right structure. Twelve undergraduate students were asked to recognize Chinese characters presented on the computer screen under seven different visual angles. The results showed that there was a significant difference in reaction time between visual angles of 10 and 19 degrees. Participants also reacted fastest and had the shortest fixation time under 10 to 11 degrees.
