A Comparative Study on the Set-size Effects in Polygon and Words in Visual Search Task

Abstract

Collection size has a very important effect on visual working memory. In this paper, we use an interview and repeated measure design to empirically investigate the relationship between larger ensemble sizes (more than four distractors) and reaction times for participant responses. We set up a scene for daily observation of polygons and words. Participants were required to identify a correctly written Chinese character and the target item, and the pentagon in the hexagon (distractor). The study found that there was no significant difference in the impact trend of large and small groups on people, and there was a high degree of consistency. At the same time, this experiment also found that the effect of ensemble size may be different for males and females. And the reaction time has a great relationship with the location of the target and the reading habits of the subjects. This requires further exploration.
