老年人同时执行两项任务的困难已经被很好地记录下来了。已经观察到，当两项任务需要相似的运动反应时，与年龄相关的双重任务成绩差异更大，而且在某些情况下，老年人也比年轻人更容易受到输入干扰的影响。作者最近观察到，即使这两项任务需要运动反应，老年人和年轻人都可以学习更快、更准确地执行视觉辨别任务和听觉辨别任务。在目前的研究中，作者将这一发现扩展到双任务条件下，包括两个需要两个运动反应的视觉任务。老年人和年轻人完成了一项双重任务培训计划，在该计划中，提供了持续的个性化自适应反馈以提高绩效。结果表明，即使有相似的运动反应和两种视觉刺激，老年人和年轻人在训练后的表现都有显著的提高，而且这种改善归因于涉及新刺激的新任务组合。这些结果表明，老年人的双重任务技能可以得到实质性的提高，而在老年人中，注意力控制的认知可塑性仍然是可能的。
Older adults’ difficulties in performing two tasks concurrently have been well documented. It has been observed that the age-related differences in dual-task performance are larger when the two tasks require similar motor responses and that in some conditions older adults also show greater susceptibility than younger adults to input interference. The authors recently observed that even when the two tasks require motor responses, both older and younger adults can learn to perform a visual discrimination task and an auditory discrimination task faster and more accurately. In the present study, the authors extended this finding to a dual-task condition that involves two visual tasks requiring two motor responses. Older and younger adults completed a dual-task training program in which continuous individualized adaptive feedback was provided to enhance performance. The results indicate that, even with similar motor responses and two visual stimuli, both older and younger adults showed substantial gains in performance after training and that the improvement generalized to new task combinations involving new stimuli. These results suggest that dual-task skills can be substantially improved in older adults and that cognitive plasticity in attentional control is still possible in old age.
