| 摘 要： | 通过考察构成视觉客体构型的两种因素在视觉工作记忆任务中的影响, 探讨了构型对视觉工作记忆绩效的作用机制。采用变化觉察实验范式, 在构型朝向不变和旋转两种条件下, 系统地控制构型中的客体相对方位和整体几何形态两种因素的变化, 考察其对视觉工作记忆绩效的影响。实验结果显示, 无论构型朝向不变还是旋转, 只要客体相对方位保持一致, 工作记忆绩效就可以维持较高水平, 而几何形态没有表现出显著作用。上述发现提示构型客体相对方位是构型影响视觉工作记忆绩效的主要因素。

| Abstract: | It has been widely acknowledged that visual working memory (VWM) only maintains and manipulates a limited amount of visual information (e.g. 3~4 objects). Studies on how VWM stores and processes objects have been effective and have yielded useful results. Previous studies in this field are focused on the processing mechanisms of individual objects. However, the mechanisms for grouping and organization of visual objects have received an increasing amount of attention recently. Among numerous types of organizations, configuration, i.e. the spatial formation of visual objects, plays a vital role in understanding the flexibility of human VWM. Many studies have shown that configuration had significant influence on VWM performance. However, configuration was usually employed as an approach to explore the effect of other factors on the memory system. Only a few studies have directly addressed the mechanism of the configuration VWM. In this study, we attempt to determine the critical factor of the information contained in a given configuration that influences VWM. We then attempt to outline the underlying mechanism of the processing in memory system for a given configuration. |
