三维图形的客体和空间工作记忆存储机制
The Storage Mechanism of Object and Spatial Working Memory for the 3-D Graphs

采用单探测变化检测范式，通过两个实验探讨了三维双特征图形在视空间工作记忆中的存储方式。实验一的记忆材料为由颜色和形状两种基本特征组成的三维图形，实验二的材料为由基本特征和细节特征组成的三维图形。被试为60名大学本科生（实验1、2各30名，年龄在19~24岁之间，平均21.25岁和21.71岁）。两个实验的结果均显示：特征交换变化条件下的记忆成绩与单一特征变化条件下最小的平均检测正确率无显著差异。这表明，由两种异质特征组成的三维图形在视觉客体和视觉空间工作记忆中均能以整合的单元进行存储。
Using single change-detection paradigm,this study explored the storage unit of visual object working memory and visual spatial working memory for the 3-D graphs with features of double dimensions.The stimulus graphs in experiment 1 were defined by basic features of color and shape,and the memory materials in experiment 2 were presented by different colors and textures.Sixty undergraduates participated two experiments (Each for 30,their age ranged from 19 to 24,mean age were 21.25 and 21.75 respectively).Results of two experiments showed that there was no significant difference between the mean detection accuracies of feature exchange condition and the worst accuracy of single feature change conditions.These findings revealed that the 3-D graphs composed of two heterogeneous features were both stored as integrated units in object working memory and spatial working memory.
