作者调查了345名成年人在短期记忆、工作记忆和长期记忆中视觉空间记忆和言语记忆过程的独特性和相互关系。从20多岁开始，处理密集型任务(例如，处理速度、工作记忆和长期记忆)会持续、有规律地下降，而言语知识在整个一生中都会增加。在一生中，记忆的认知结构几乎没有区别。视觉空间记忆和言语工作记忆是截然不同但高度相关的系统，具有特定领域的短期记忆子系统。与最近的神经成像数据相比，与年轻人相比，几乎没有证据表明老年人在行为水平上的功能去分化。作者的结论是，努力将行为数据和大脑数据联系起来，可以更全面地了解衰老的大脑。
The authors investigated the distinctiveness and interrelationships among visuospatial and verbal memory processes in short-term, working, and long-term memories in 345 adults. Beginning in the 20s, a continuous, regular decline occurs for processing-intensive tasks (e.g., speed of processing, working memory, and long-term memory), whereas verbal knowledge increases across the life span. There is little differentiation in the cognitive architecture of memory across the life span. Visuospatial and verbal working memory are distinct but highly interrelated systems with domain-specific short-term memory subsystems. In contrast to recent neuroimaging data, there is little evidence for dedifferentiation of function at the behavioral level in old compared with young adults. The authors conclude that efforts to connect behavioral and brain data yield a more complete understanding of the aging mind.
