目的:探讨场独立和场依存两种场认知风格在观察道路场景图片时是否存在差异,为驾驶员认知风格与道路场景注视的相关性提供科学依据。方法:随机选取南通大学本科生90例,通过预实验筛选出两种认知风格被试共48例,运用眼动仪观察其在兴趣区内的注视点数目,首次注视到兴趣区的时间以及在兴趣区内的持续注视时间。结果:两种认知风格的被试在道路场景图片兴趣区内的注视点数目有显著差异(P〈0.05),首次注视到兴趣区的时间有显著差异(P〈0.05),而在兴趣区内的平均注视持续时间并不存在显著差异(P>0.05)。结论:认知风格对道路场景注视有影响,观察道路场景图片时,场独立型者能更快注视到兴趣区,在兴趣区内的注视点数目更多。
Objective: To explore the differe nces between the two field cognitive styles while observing road scene pictures. Methods:90 undergraduates from Nantong University were randomly selected as pre-experiment subjects, and 48 subjects were selected through the pre-experiment, and the data of fixation counts, time to first fixation and the average fixation duration in AOIs were collected with an eye tracker. Results: Fixation counts in AOIs of this two field cognitive styles of people had significant difference(P0.05). Conclusions: Cognitive styles had influence on road scene observing, field-independence people could pay faster attention to AOIs faster, and their fixation counts in AOIs were more while they were observing road scene pictures.
