摘要: 探究了gap效应对视觉搜索任务中搜索目标的显著性和搜索绩效的影响。采用gap值(11种时间值)×极性(正极性和负极性)×角度(30°/60°, 20°/70°) 3因子组内设计实验,18名被试在不同gap值、极性和角度组合条件下完成一系列视觉搜索任务,测量指标为发现目标物的概率和反应时间。结果表明,gap值、角度及二者的交互作用对搜索目标的显著性有显著影响,gap值和极性对反应时间有显著影响,即gap效应对视觉搜索任务中搜索目标的显著性和搜索绩效均有显著影响。

Abstract: The study aimed to investigate the gap effect on the salience of search target and performance in visual search tasks considering two display polarity modes and two angle combination modes. In this study, a three-factor within-subjects design experiment was conducted (11 gap value×2 polarity×2 angle combination). 18 subjects participated in this study and completed a series of visual search tasks under different combinations of gap values, display polarity modes and angle combination modes. The target detection probability and reaction time were measured. The results indicated that the main effects and interaction of gap value and angle combination on target salience were significant while the main effects of gap value and polarity on reaction time were significant. Gap effect showed significant influences on target salience and search performance.

Key words: visual search, salience, gap effect, display polarity, human factors
