We analyzed age-related slowing in 29 younger (M = 22 years) and 30 older adults (M = 70 years) who performed a conceptual comparison task, a naming task, and a simple reaction time task. Both vocal and manual responses were elicited in all except the naming task. Results did not support the hypothesis that there is greater age-related slowing in comparison tasks than in production tasks. In contrast, we found an interaction between age and response modality in the conceptual comparison task. Response latencies of younger participants were shorter in the manual modality whereas those of older participants were shorter in the vocal modality. In the simple reaction time task manual responses were faster in the two age groups. These findings are discussed in relation to models assuming task-specific slowing factors.
我们分析了29名较年轻成年人（平均年龄22岁）和30名较年长成年人（平均年龄70岁）与年龄相关的反应迟缓情况，这些参与者完成了一项概念比较任务、一项命名任务和一项简单反应时任务。除命名任务外，在所有任务中都引发了言语和手动反应。结果并不支持以下假设：与生产任务相比，比较任务中与年龄相关的反应迟缓更为明显。相反，我们发现在概念比较任务中年龄与反应方式之间存在交互作用。较年轻参与者在手动反应方式下的反应潜伏期较短，而较年长参与者在言语反应方式下的反应潜伏期较短。在简单反应时任务中，两个年龄组的手动反应都更快。我们将结合假设任务特定减缓因素的模型来讨论这些发现。
