摘要: 采用记忆任务与视觉搜索任务相结合的范式,以二维对称图形为材料,探讨视觉工作记忆内容对视觉搜索的影响。结果发现:(1)不同视觉工作记忆内容条件下的反应时存在显著差异,无效信息条件下的反应时显著长于有效信息条件下的反应时。(2)不同搜索序列条件下反应时差异显著,复杂序列条件下的反应时显著长于简单序列条件。结果表明,视觉工作记忆中的信息内容影响视觉搜索效率,其变化趋势不受序列大小的影响,结果支持偏向竞争模型。

关键词: 视觉工作记忆, 信息内容, 视觉搜索

Abstract: With the combined memory task and visual search paradigm, using 2-D abstractly symmetric shapes as materials,this study aimed to discuss the influence of contents of visual working memory to visual search. The results showed that:(1)the effect of the contents of visual working memory was significant. And the RTs were significantly longer in the invalid condition than in the valid condition.(2)there was a significantly difference in the effect of display type, showing that the RTs in the complex display was significantly longer than that in the simple display. The results suggested that the information which was maintained in visual working memory could affect the visual search efficiency and the display size did not change the trend of RTs. The findings supported biased competition model.

Key words: visual working memory, information contents, visual search
