本研究的目的是根据Logic的工作记忆模型（1995），评估年龄对视觉和空间工作记忆储存的影响。在第一个实验中，年轻人，老年人和非常老的受试者进行了两项任务，通常用于测量视觉广度（视觉模式测试）和空间广度（Corsi块敲击测试）。在第二个实验中，我们修改了视觉模式测试的编码时间，使其与Corsi块敲击测试相同。结果表明，随着年龄的增长，视觉广度比空间广度减少更多，即使在控制视觉模式测试和Corsi块敲击测试之间的编码时间。这些结果支持视觉空间工作记忆的分级，并表明，更明显的年龄相关效应的视觉广度是强大的和独立的编码时间。
The aim of this study was to evaluate the effect of aging on the storage of visual and spatial working memory according to Logic's model of working memory (1995). In a first experiment young, elderly, and very old subjects carried out two tasks usually used to measure visual span (Visual Patterns Test) and spatial span (Corsi Block Tapping test). In the second experiment, we modified the encoding time of the Visual Patterns Test so that it was the same as in the Corsi Block Tapping test. Results indicate that the visual span decreases more with advanced age than the spatial span, even when the encoding time between the Visual Patterns Test and the Corsi Block Tapping test is controlled. These results support the fractionation of the visuo-spatial working memory and show that the more pronounced age-related effect on the visual span is robust and independent of the encoding time.
