作者检查了视觉短期记忆（VSTM）的组织。通过使用变更检测任务，他们报告说VSTM存储了各个项目之间的关系信息。这种关系处理是通过将项目组织成空间配置来调解的。视觉对象的空间结构对于空间位置、颜色和形状的VSTM非常重要。当颜色VSTM与位置VSTM进行比较时，空间配置起着不可或缺的作用，因为对于颜色VSTM，配置很重要，而对于位置VSTM，颜色不重要。作者还研究了注意力的作用，发现构型的形成受到自上而下和自下而上的注意因素的调节。综上所述，作者提出VSTM在全局空间配置的基础上存储单个视觉项目的关系信息。
The authors examined the organization of visual short-term memory (VSTM). Using a change-detection task, they reported that VSTM stores relational information between individual items. This relational processing is mediated by the organization of items into spatial configurations. The spatial configuration of visual objects is important for VSTM of spatial locations, colors, and shapes. When color VSTM is compared with location VSTM, spatial configuration plays an integral role because configuration is important for color VSTM, whereas color is not important for location VSTM. The authors also examined the role of attention and found that the formation of configuration is modulated by both top-down and bottom-up attentional factors. In summary, the authors proposed that VSTM stores the relational information of individual visual items on the basis of global spatial configuration.
