It is well established that performance on the Wisconsin Card Sorting Test (WCST) tends to decline with advanced age, but the reason for this decline has not been established. The objective of the present study was to clarify this question using a qualitative approach to the task. The WCST was administered to 19 older adults and 25 younger participants. In addition to standard testing procedures, all participants were asked to verbalize their response strategy when placing each card. Results of this procedure implicate poor set shifting and set maintenance, consistent with reduced efficiency of feedback utilization, as the primary cause for age-related decline on the WCST.
众所周知，威斯康星卡片分类测试（WCST）的表现往往会随着年龄的增长而下降，但这种下降的原因尚未明确。本研究的目的是通过对该任务采用定性方法来阐明这个问题。对19名老年人和25名年轻人进行了WCST测试。除了标准测试程序外，所有参与者在放置每张卡片时都被要求说出他们的反应策略。这一程序的结果表明，较差的定势转换和定势维持，与反馈利用效率降低一致，是WCST中与年龄相关下降的主要原因。
