对老年人和年轻人的信息整合类别学习进行了研究。准确性结果表明，在线性和非线性条件下，老年参与者的学习效果都不如年轻参与者。基于模型的分析表明，在线性条件下，两组都倾向于使用信息整合，但在训练后期，年轻参与者更有可能这样做。相比之下，在非线性条件下的两组使用信息整合的可能性相同。进一步的分析表明，当采用信息整合方法时，年轻人比老年人更准确，而当使用基于规则的方法时，观察到的年龄相关差异较小，这表明年龄可能对信息整合类别学习过程产生负面影响，但对基于规则的学习影响较小。
Information-integration category learning was examined in older and younger adults. Accuracy results indicated that older participants learned less well than younger participants in both linear and nonlinear conditions. Model-based analyses indicated that both groups in the linear condition tended to use information integration but that later in training younger participants were more likely to do so. In contrast, the 2 groups in the nonlinear condition were equally likely to use information integration. Further analysis indicated that younger adults were more accurate than older adults when an information-integration approach was adopted, whereas fewer age-related differences were observed when a rule-based approach was used, suggesting that age can have a negative impact on information-integration category learning processes but less impact on rule-based learning.
