采用视觉搜索任务范式,以不同视觉工作记忆容量大学生为被试,探讨了视觉工作记忆对自上而下注意控制的影响。结果发现:(1)视觉工作记忆内容影响自上而下注意控制,靶相关信息促进对靶的搜索,而靶无关信息干扰对靶的记忆搜索。(2)不同视觉工作记忆容量个体的自上而下注意控制能力存在差异,高视觉工作记忆容量被试的反应时显著短于低视觉工作记忆容量被试,说明视觉工作记忆负荷影响自上而下注意控制。
Using the visual search task paradigm, students with different visual working memory capacity were tested to explore the impact of visual working memory on top-down attention control. The results showed that: (1) The content of visual working memory affected the top-down attention control, the target related information promoted the search of target, and the target-independent information interfered with the memory search of target. (2) There were differences in top-down attention control ability among individuals with different visual working memory capacities. Response time of participants with high visual working memory capacity was significantly shorter than those with low visual working memory capacity, indicating that the impact of visual working memory load from the top Pay attention to control.
