为了找出与年龄相关的概念形成缺陷的来源，年长和年轻的成年人完成了新的概念匹配测试-选择性注意测试和分类测试-概念形成的标准化测试。老年人表现出完整的概念识别能力，即从刺激特征中产生抽象概念的能力，但当存在无关特征时，可以观察到年龄差异。此外，选择性注意力，而不是概念识别能力，预测了分类测试中与年龄相关的下降。因此，老年人的概念形成减少可能源于抽象能力以外的能力下降。
In order to identify the source of age-related deficits in concept formation, older and younger adults completed a new Concept Matching Test, tests of selective attention, and the Sorting Test, a standardized test of concept formation . Older adults showed intact concept identification, the ability to generate abstract concepts from stimulus features, but age differences were observed when irrelevant features were present. In addition, selective attention, but not concept identification ability, predicted age-related declines on the Sorting Test. Thus, reduced concept formation in older adults may stem from declines in abilities other than the capacity for abstraction.
