本研究采用两种不同呈现方式的视觉和空间工作记忆任务，比较了年龄对视觉和空间工作记忆的影响。工作记忆任务包含同时和顺序呈现模式条件，分别反映视觉和空间工作记忆过程。年轻和年长的参与者必须在三种不同的条件下记住五个相等物体的位置：基线（立即回忆），维持（包括5秒的延迟）和操纵（例如，将所有对象向右重定位一列）条件。只有老年人表现较差的顺序相比，同时基线条件，只有这组显示较低的性能顺序延迟相比，同时延迟条件。然而，在这两组的操作条件影响性能的同时和顺序呈现模式在相同程度上。因此，本研究的结果部分支持视觉和空间工作记忆之间的年龄相关的分化，更强的年龄效应的空间比视觉工作记忆。
The present study was intended to compare age effects on visual and spatial working memory by using two versions of the same task that differed only in presentation mode. The working memory task contained both a simultaneous and a sequential presentation mode condition, reflecting, respectively, visual and spatial working memory processes. Young and older participants had to remember the locations of five equal objects under three different conditions: a baseline (immediate recall), a maintenance (including a delay of 5 seconds), and a manipulation (e.g., relocate all objects one column to the right) condition. Only older adults performed worse on the sequential compared to the simultaneous baseline condition and only this group revealed lower performance on the sequential delay compared to the simultaneous delay condition. However, in both groups the manipulation condition affected performance on the simultaneous and sequential presentation modes to the same extent. The findings of this study therefore partially support an age-related differentiation between visual and spatial working memory, with a stronger age effect on spatial than on visual working memory.
