【摘要】 以25名大学生为被试,采用眼动记录法结合双任务范式探讨工作记忆对视觉搜索的引导作用。结果发现:在工作记忆与视觉搜索内容相匹配的条件下,工作记忆可以对视觉搜索起引导作用,对视觉搜索具有自上而下的影响。而在工作记忆与视觉搜索内容不匹配的条件下,由于受到工作记忆容量的限制,工作记忆内容会对视觉搜索产生干扰作用。研究结果验证了偏好竞争模型。更多还原

【Abstract】 This research used the method of eye movement and through the dual-task paradigm to explore the guidance function of working memory for visual search.25 college students took part in this experiment.The results indicated that working memory could play a guiding role in visual search with a top-down influence on visual search when they were matched.On the other hand,if they were not matched,working memory would interfere with visual search because of the capacity of working memory,which verified the biased competition model.更多还原
