对称性信息呈现方式对道路交通标志视认绩效的影响

本实验研究了道路交通标志中路名信息的对称性和布局方式对视认绩效的影响。实验采用延迟匹配任务的方法,共有18名被试参加了实验。实验结果表明：①道路交通标志路名信息以对称性方式呈现时,被试的正确率和反应时等操作指标明显优于非对称结构呈现条件下的操作指标;②道路交通标志路名信息以矩形或者圆形方式呈现时,被试的操作指标没有显著的差别。可以认为：对于不同的布局方式,对称空间结构都可以明显提高被试对道路交通标志的视认绩效。

Symmetry of Information Presentation Form Influence on Recognition Performance of Road Traffic Signs

The research explored the symmetry and layout in operation performance of road traffic signs. The experiment used delayed matching tasks by studying 18 participants. The results showed that: the operation performance for symmetrical structure of traffic signs was faster and more accurate than for asymmetrical structure of traffic signs as symmetry of information presentation form was used. There were no significant difference between rectangle and circularity. It was concluded that operation performance of traffic signs could be significantly improved by symmetrical space structure in both of layouts.
