字体特征与搜索方式对视觉搜索反应时的影响

The Influence of Chinese Character Features and Searching Methods on Visual Search

采用视觉搜索程序和实验内省法考察了汉字字体、字体大小和搜索方式对视觉搜索反应时的影响。实验结果表明:(1)字体大小相同情况下,宋体的视觉搜索反应时极其显著的少于楷体;字体相同情况下,22磅字的视觉搜索反应时显著少于15磅字。(2)性别因素对视觉搜索过程无影响。(3)搜索方式并非如Jeremy M.Wolfe所言的只有自由搜索一种,还包括系统搜索;在复杂任务中两种搜索方式的人数和反应时差异均不显著。

By using visual search procedures and experimental methods of introspection, this research studied how factors, such as the feature and the size of Chinese characters, searching methods, affected visual search time. The result showed that First, the Normal Song type in the same size took less visual search time. The 22-pound type of the same feature took less visual search time; second, sexes made no difference in terms of visual search time; third, unlike Jeremy M. Wolfe, the searching methods not only included free search, but also systemic search. But in complex tasks, there was little difference between the two search methods.
