摘　　要：由于在预实验中发现记忆复合物体 (multi-featureobjects)时存在子系统优势 ,在本实验中 ,研究了记忆单特征物体 (single -featureobjects)时 ,是否存在子系统优势。被试为中国科学技术大学学生 17人。要求被试记忆同样数目的单特征物体 ,条件 1下物体属性相同 ,条件 2下物体分属两种属性。通过正确率分析 ,条件 2的成绩好于条件 1。这个结果表明 :单特征物体记忆时存在子系统优势。The aim of this study was to find out whether ”subsystem superiority” exists w he n remembering single-feature objects, because in pre-experiment it was found that accuracy was better when two subsystems were involved in memory task than w hen only one subsystem is involved when multiple-feature objects were remembere d. Ss were 17 students in University of Science and Technology of China. Ss were required to remember single-feature objects of the same number. In Condition 1 , objects had the same kind of feature, while in condition 2, objects were cl assified into two features. The accuracies in both conditions were compared and it was found that the accuracy of condition 2 was better than that of condition 1. The result suggests ”subsystem priority” exists when remembering single-fe ature objects.
