通过提出2个简单的任务，探讨了年轻人和老年人的双任务差异，第二个任务相对于第一个任务的开始仔细控制。通过要求对两项任务进行手动响应或对第一项任务进行手动响应并对第二项任务进行口头响应，探索了产生和执行2个类似运动程序的能力与年龄相关的降低的可能性，并得到了证据的证实。与年龄相关的干扰大于老年人处理过程普遍减慢的预期。通过在视觉模态中呈现两个任务或在听觉模态中呈现第一个任务和在视觉模态中呈现第二个任务，探索了在相同的感知输入模态中处理2个任务的能力与年龄相关的降低的可能性，并且没有证据支持。当两项任务处于相同模式时，干扰更大，但对于老年人和年轻人来说是等效的。双任务干扰的年龄差异似乎相当本地化的反应生成过程。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Dual-task differences in younger and older adults were explored by presenting 2 simple tasks, with the onset of the 2nd task relative to the 1st task carefully controlled. The possibility of an age-related reduction in the ability to generate and execute 2 similar motor programs was explored by requiring either a manual response to both tasks or a manual response to the 1st and an oral response to the 2nd and was confirmed by the evidence. The age-related interference was greater than would be expected from a general slowing of processing in older adults. The possibility of an age-related reduction in the capacity to process 2 tasks in the same perceptual input modality was explored by presenting both tasks in the visual modality or the 1st task in the auditory modality and the 2nd task in the visual modality and was not supported by the evidence. There was greater interference when both tasks were in the same modality, but it was equivalent for older and younger adults. Age differences in dual-task interference appear quite localized to response-generation processes.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
