语义大小与刺激数量在非对称性视觉搜索中的作用

The roles of semantic size and number of stimuli in asymmetric visual search

为了探讨语义与刺激数量在非对称视觉搜索中的作用,研究采用不同语义大小的名词汉字,并指导被试在6和12两种刺激数量中搜索目标刺激。结果发现:(1)当刺激数量为6时,语义较小目标刺激的搜索效率高于语义较大目标刺激;(2)当刺激数量为12时,语义较大目标刺激的搜索效率高于语义较小目标刺激;(3)当搜索的干扰刺激和目标刺激语义大小一致时,数量多且语义较大的干扰刺激搜索效率更低。这表明语义大小与刺激数量对非对称视觉搜索存在交互影响,支持具身认知理论,并扩充了特征整合理论和引导搜索模型。

For investigating the roles of semantic size and number of stimuli in asymmetric visual search,we adopted the different semantic sizes of Chinese characters and instructed the participants to search target stimulus in two types of stimulus numbers:6 and 12.Results showed that:(1)When the number of stimuli was 6,the search efficiency of the target with the small semantic size was higher than that of the target with the large semantic size;(2)When the number of stimuli was 12,the search efficiency of the target with the larger semantic size was higher than that of the target with smaller semantic size;(3)When the semantic size of the interferential stimuli and the target stimuli were the same,the search efficiency of the interferential stimuli with more number and large semantic size was slower.This study confirmed the interaction of spatial and numerical representations in asymmetric visual search,which supported embodied cognition theory,and extended the feature integration theory and guided search model.
