摘要
以反应时和正确率为指标 ,研究了在不同难度和呈现背景 ,下划线突显方法对视觉搜索绩效的影响。实验结果表明 :下划线作为突显方法对被试的视觉搜索绩效有显著的促进作用 ;在高难度水平下的视觉搜索作业中 ,下划线对被试的视觉搜索绩效的促进作用更为明显 ;在高难度条件下 ,与黑背景下被试的绩效相比 ,白背景下被试的搜索绩效明显较优。
The experiment was conducted to investigate the visual performance of underline highlighting at different difficulty levels and display backgrounds. Correct rate and reaction time were analyzed. The results were as follows:1.Underline as a kind of highlighting,has a significant positive effect on the performance of visual search,especially in the condition of high difficulty level. 2.On high difficulty levels,the visual performance on the white background is superior to on the black background.
