摘要:
该研究采取记忆探测任务与视觉搜索任务相结合的双任务实验范式，以彩色边框几何图形为材料，探究视觉工作记忆内容在形状凸显条件下对视觉注意的引导作用。实验设计为2 × 2的混合实验设计，其中不同凸显条件(匹配分心物凸显、搜索目标凸显)为被试间变量，不同匹配类型(有匹配项、无匹配项)为被试内变量。结果发现：不同凸显条件下，无匹配项的视觉搜索反应时皆显著小于有匹配项的视觉搜索反应时。这说明视觉工作记忆中的信息内容对于视觉注意的引导作用是十分有效的。
Abstract:
This study adopted the dual task paradigm combined with memory mission and visual search task, to explore the guiding role of visual working memory content toward visual attention via using color and frame geometry as the materials. It was a 2 × 2 mixed experimental design in this research, which respectively adopted different highlight condition (match the distraction highlight vs. search target highlight) and matching types (match vs. dismatch) as between-subject variable and within-subject variable. The results showed that under different highlight conditions, the visual search reaction time in the mismatches condition is shorter than that in the matches condition. The results, thus, demonstrate that the information content of visual working memory can effectively guide the visual attention.
