作者研究了短期视觉空间和言语记忆过程之间的独特性和相互关系。在职的。 345 名成年人的长期记忆。从20世纪20年代开始。连续的。处理密集型任务（例如处理速度、工作记忆和长期记忆）会定期下降，而言语知识在整个生命周期中都会增加。在整个生命周期中，记忆的认知结构几乎没有差异。视觉空间和言语工作记忆是不同但与特定领域的短期记忆子系统高度相关的系统。与最近的神经影像学数据相比，几乎没有证据表明老年人与年轻人相比在行为水平上存在功能去分化。作者得出的结论是，将行为和大脑数据联系起来的努力可以让人们更全面地了解衰老的思维。
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.
