通过2个实验考察了衰老、注意过程和运动的关系。首先，研究了两项注意力任务的年龄差异：分时任务和注意力灵活性任务。与老年人相比，年轻人的注意力在两个顺序任务之间的交替速度更快，同时处理两个任务的效率也更高。然后研究了有氧运动对老年人同样两项注意力任务的影响。在10周的锻炼计划之后，老年锻炼者在交替速度和分时效率方面比老年对照组表现出更大的改善。有趣的是，这种锻炼效果只针对双任务处理。两组学生在单任务表现上表现出相同的效果。这些结果表明，有氧运动可以对老年人至少两种不同的注意力过程的效率产生有益的影响。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Investigated the relationship among aging, attentional processes, and exercise in 2 experiments. First, age differences were examined on 2 attentional tasks: a time-sharing task and an attentional flexibility task. Young adults alternated attention between 2 sequenced tasks more rapidly and time-shared the processing of 2 tasks more efficiently than older adults. Then the effect of aerobic exercise was investigated on the same 2 attentional tasks in older adults. Following the 10-wk exercise program, older exercisers showed substantially more improvement in alternation speed and time-sharing efficiency than older controls. Interestingly, this exercise effect was specific to dual-task processing. Both groups of Ss showed equivalent effects on single-task performance. These results indicate that aerobic exercise can exert a beneficial influence on the efficiency of at least 2 different attentional processes in older adults.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
