Bimanual 1:1 rhythmic coordination was performed while retrieving words from a specified category. The effects of divided attention (DA) on coordination were indexed by changes in mean relative phase and recurrence measures of shared activity between the two limbs. Effects of DA on memory were indexed by deficits in exemplars retrieved relative to the baseline. Shifts in relative phase were found, accompanied by a recall deficit for DA during the retrieval task. DA also reduced the degree of shared activity between left and right rhythmic motions. Our discussion focuses on DA-induced parameter changes in retrieval and coordination dynamics, as well as on the hypothesis that stability is the general factor mediating dual-task performance.
在从指定类别中检索单词时进行双手 1:1 节奏协调。通过平均相对相位的变化和两肢之间共享活动的重现测量来衡量分心（DA）对协调的影响。DA 对记忆的影响通过相对于基线检索的范例中的缺陷来衡量。发现了相对相位的变化，同时在检索任务期间 DA 存在回忆缺陷。DA 还降低了左右节奏运动之间的共享活动程度。我们的讨论集中在 DA 引起的检索和协调动力学中的参数变化，以及稳定性是介导双任务表现的一般因素这一假设上。
