本研究探讨了在衰老过程中观察到的两种类型的减慢（一般处理速度的丧失和自发节奏的减慢）之间的关系，试图验证存在一种内部计时机制负责认知年龄相关性下降的假设。处理速度已被评估为年龄和工作记忆之间的关系，同时与自发的克里思措施的调解人。作者比较了年轻人和老年人在涉及自发运动克里思、处理速度和工作记忆的任务上的表现。研究结果证实了与年龄相关的自发运动克里思减慢，但并没有表明克里思调解在工作记忆下降方面的优势。加工速度似乎是工作记忆的主要中介，但也是自发克里思减慢的主要中介。
This research studied the relationships between two types of slowing observed in aging-loss of general processing speed and slowing of spontaneous tempo-in an attempt to test the assumption that there is an internal timing mechanism responsible for cognitive age-related decrease. Processing speed has been evaluated as a mediator of the relationship between age and working memory, concurrently with spontaneous tempo measures. The authors compared the performance of young and older adults on tasks involving spontaneous motor tempo, processing speed, and working memory. The findings confirmed the age-related slowing of spontaneous motor tempo but did not indicate superiority of tempo mediation in the decline in working memory. Processing speed appeared to be a major mediator of working memory, but also of spontaneous tempo slowing.
