本研究旨在探讨成人视觉空间记忆的结构。40-89岁的成年人（n=160）执行简单存储和复杂的视觉空间跨度任务。简单的存储任务被分为三种呈现格式：(i)视觉，涉及保持形状和纹理；（ii）空间序列，即维持按顺序呈现的地点；（iii）空间同步，这涉及保持地点的模式。验证性因子分析表明，在域分化模型中，考虑视觉空间记忆的简单视觉、空间顺序和空间同时成分以及复杂视觉空间记忆的域分化模型与我们的数据拟合良好。结构方程模型还表明，年龄对视觉记忆、空间顺序记忆和空间同时记忆以及复杂视觉空间记忆有直接影响。综上所述，这些结果表明，考虑所涉及的处理类型（在简单存储与复杂的视觉空间任务中）和视觉空间域中刺激的呈现格式的重要性。(C) 2013爱思唯尔公司版权所有。
The present study aimed to investigate the structure of visuospatial memory in adulthood. Adults 40-89 years of age (n=160) performed simple storage and complex visuospatial span tasks. Simple storage tasks were distinguished into three presentation formats: (i) visual, which involved maintaining shapes and textures; (ii) spatial-sequential, which involved maintaining sequentially-presented locations; and (iii) spatial-simultaneous, which involved maintaining patterns of locations. Confirmatory factor analyses showed that, among the domain-differentiated models, the one considering visuospatial memory in its simple visual, spatial-sequential and spatial-simultaneous components and complex visuospatial memory yielded a good fit to our data. Structural equation modeling also showed that age had a direct effect on visual, spatial-sequential and spatial-simultaneous memory, and on complex visuospatial memory. Altogether these results suggest the importance of considering both the type of processing involved (in simple storage vs. complex visuospatial tasks) and the presentation format of the stimuli in the visuospatial domain.
