Abstract

A dual-task procedure was used to examine capacity demands of letter-matching in younger and older adults. Older subjects generally were slower on both tasks than were younger adults, but this difference was especially pronounced for the late stages of category matching, suggesting that retrieval and comparison of category information is particularly demanding for older adults.

摘要

采用双任务程序来检验年轻人和老年人在字母匹配任务中的认知能力需求。一般来说，老年受试者在两项任务上的速度都比年轻成年人慢，但这种差异在类别匹配的后期阶段尤为明显，这表明对老年人来说，类别信息的检索和比较尤其困难。
