Abstract: 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.

Key words: object working memory, spatial working memory, storage mechanism
