呈现方式对小学生和大学生分类影响的眼动研究

Eye Movement Researches into Effect of Stimuli Presenting Mode on Classification of Undergraduates and Pupils

使用ASL-504型眼动仪,采用2×2的被试间设计,对22名智力、视力均正常的小学生和24名大学生在两种呈现方式下的分类结果和主要眼动指标加以考察。结果表明:(1)小学生分类结果不存在显著的呈现方式差异,大学生分类结果存在显著的呈现方式差异。(2)被试分类结果是否存在显著的呈现方式差异与其兴趣区数目、注视次数、注视频率、注视点持续时间等眼动指标在相应条件下是否存在显著差异是一致的。

The ASL 504 eye tracker was used in the experiment. The experiment is 2 × 2 inter- subjects design. Classification index and the main eye movement index are investigated by using 24 undergraduates and 22 pupils as subjects. The sights of the undergraduates were normal, the intelligence and sights of the pupils are both normal on one stimuli picture which was presented in 2 conditions. The results are as follows： （ 1 ） The effect of stimuli presenting mode on classification of the undergraduates was significant while it was not significant on that of the pupils. （2） whether there are significant differences of stimuli - presenting mode between classification of the pupils and undergraduates is consistent with whether there are significant differences of eye movement index in the homologous condition between them, including the numbers of area of interest, times of fixation, frequency of fixation and duration of each fixation in the homologous condition. It doesn＇t go all the way with the duration of fixation.
