在感觉运动同步中对克里思变化的适应假设取决于两个过程，一个（相位校正）在很大程度上是自动的，另一个（周期校正）需要有意识的意识和注意力。在这项研究中，参与者敲击他们的手指同步听觉序列包含克里思的变化，并继续敲击序列终止后。他们的意图，以适应或不适应的克里思变化，通过指令操纵，他们的注意力资源的变化，通过引入并发的次要任务（心算），和他们的克里思变化的意识通过知觉判断进行评估。正如预测的那样，发现周期校正强烈依赖于所有三个变量，而相位校正仅取决于意图。
Adaptation to tempo changes in sensorimotor synchronization is hypothesized to rest on two processes, one (phase correction) being largely automatic and the other (period correction) requiring conscious awareness and attention. In this study, participants tapped their finger in synchrony with auditory sequences containing a tempo change and continued tapping after sequence termination. Their intention to adapt or not to adapt to the tempo change was manipulated through instructions, their attentional resources were varied by introducing a concurrent secondary task (mental arithmetic), and their awareness of the tempo changes was assessed through perceptual judgements. As predicted, period correction was found to be strongly dependent on all three variables, whereas phase correction depended only on intention.
