我们调查老龄化是否会导致离散和连续双手协调任务的全球性下降,这些任务被认为依赖于不同的控制机制,用于肢体的时间耦合。所有条件下的连续双手画圈与年龄相当的时间控制。这也适用于离散的同时攻丝。老年人的手之间的协调缺陷是特定的离散敲击条件下,需要异步intermanual定时,并与自我报告的执行功能障碍(DEX)问卷。此外,老年人只显示了最困难的双手转圈条件和工作记忆的测量之间的关系。因此,双手协调的年龄相关变化是特定的任务条件下,把复杂的时间要求的左手和右手的动作,因此,可能需要执行控制。
We investigate whether aging leads to global declines in discrete and continuous bimanual coordination tasks thought to rely on different control mechanisms for temporal coupling of the limbs. All conditions of continuous bimanual circle drawing were associated with age-equivalent temporal control. This was also true for discrete simultaneous tapping. Older adults’ between-hand coordination deficits were specific to discrete tapping conditions requiring asynchronous intermanual timing and were associated with self-reported executive dysfunction on the Dysexecutive (DEX) questionnaire. Also, older adults exclusively showed a relationship between the most difficult bimanual circling condition and a measure of working memory. Thus, age-related changes in bimanual coordination are specific to task conditions that place complex timing demands on left and right hand movements and are, therefore, likely to require executive control.
