Task switching performance was assessed in a group of healthy young, healthy old, and MCI-diagnosed participants. Highly significant RT-related local switch costs were found in the MCI group. This contrasts the typical finding that in normal aging local switch costs show no age-related deficit. Local switch costs deficits may be a diagnostic tool in differentiating normal and pathological cognitive aging.

在轻度认知障碍中增加了本地转换成本。

在一组健康的年轻，健康的老年人和经MCI诊断的参与者中评估了任务转换性能。在MCI组中发现与RT相关的本地交换机成本非常高。这与通常的发现相反，在正常的老化过程中，本地转换成本不会显示与年龄相关的赤字。本地转换成本赤字可能是区分正常和病理性认知老化的诊断工具。
