本研究采用标准版加州卡片分类测验和两个改进版卡片分类测验，通过两个实验考察了注意和工作记忆对成年人概念识别年龄差异的贡献。老年人表现出全球减少，他们的能力，以确定概念是否排序刺激，确定概念所使用的考官，或产生的概念线索。虽然在选择性注意和干扰控制的年龄差异并没有导致这些赤字，减少工作记忆占与年龄相关的持续性错误的增加。我们的结论集中在工作记忆的损伤是否可以充分解释概念识别的年龄差异。
The contributions of attention and working memory to adult age differences in concept identification were examined in two experiments using the standard version of the California Card Sorting Test plus two modified versions. Older adults demonstrated global reductions in their ability to identify concepts whether sorting stimuli, identifying concepts used by the examiner, or generating concepts from cues. Although age differences in selective attention and interference control did not contribute to these deficits, reduced working memory accounted for the age-related increase in perseverative errors. Our conclusions focus on whether impairments in working memory might fully account for age differences in concept identification.
