摘要
采取专家—新手范式,利用眼动仪记录专家运动员、一般运动员和新手在观察运动情境图片时的眼动规律,了解排球运动员的视觉信息特征,分析被试的注视次数、注视时间、眼跳距离等眼动指标。研究表明,专家组对排球情境图片信息的加工更为细致,他们的首、次注视点时间较长,注视次数少,注视持续时间较长,与新手组有显著差异。专家组的注视范围较为宽广,注视点少而分散。被试的注视多以球的位置为中心,向四周呈放射状散开,重要信息区内都有较多的视觉注视。图片材料的不同对于被试的首注视点、次注视点时间以及瞳孔直径有显著影响。
For the purpose of understanding the visual information characteristics of volleyball players, this study used expert-novice paradigm and eye tracking system, and recorded saccade indicators, such as fixation number, saccade, fixation frequency The results revealed that the first and second fixations of expert group last longer than novice group and obvious distinctions existed between them. As for expert group, the fixation numbers are fewer but the duration is longer, the fixation scope is broader but the fixation spots are fewer and dispersed. The differences of picture materials have a conspicuous effect on the first fixation, the second fixation time and pupil diameter.
