The Influence of Graph′s Regulation Character on the Storage of Object and Spatial Working Memory

Abstract

Abstract: The study investigated the storage mechanism of visual object working memory and visual spatial working memory for the graphs with features of single dimension using change-detection paradigm, and measured their capacities. The results showed, the memory score of regular graphs was significantly higher than that of irregular graphs in object working memory, but there was no difference between them in spatial working memory. The storage capacity of spatial working memory was significantly higher than that of object working memory, there were respectively 4-5 positions and 3-4 objects. These suggested graph′s regulation character impacted the storage of object working memory but didn′t impact that of spatial working memory. The graphs with features of single dimension were stored by the unit of feature in object working memory but stored by the way of integer in spatial working memory.

Key words: object working memory, spatial working memory, store, capacity, graph.

摘要： 采用单探测变化检测范式,考察了单维度特征图形在视觉客体和视觉空间工作记忆中的存储机制,并对这两种视觉工作记忆的容量进行测定。结果显示,在客体工作记忆中,规则图形的记忆成绩显著高于不规则图形,但在空间工作记忆中,这两种图形的记忆成绩无显著差异;空间工作记忆的存储容量显著大于客体工作记忆容量,分别为4-5个位置和3-4个客体。这表明,图形规则性影响了客体工作记忆的存储但不影响空间工作记忆的存储,由单维度特征组成的图形在客体工作记忆中是以特征为单元储存,而在空间工作记忆中是以整合方式储存。
