本研究旨在确定偏好协调模式的稳定性是否可以被有意改变，以及这种稳定性是否涉及额外的注意负荷。8名受试者执行同相和反相双手协调模式，一项反应时(RT)任务，以及几项双重任务(协调+RT)，这些任务通过要求共享注意力、优先于协调任务或优先于RT任务来操纵注意优先级。结果表明，同相的RT小于反相的RT。此外，注意操作导致了模式稳定性和反应时成绩之间的权衡。这表明，执行并有意稳定协调模式会招致取决于协调模式的动态属性的中心成本。因此，这项研究在信息处理和动态协调方法之间开辟了一座概念和方法的桥梁。(《心理信息组织数据库记录》(C)2016年《行政程序法》，版权所有)
This study aimed to determine whether the stability of preferred coordination patterns could be modified intentionally and whether such stabilization involved an additional attentional load. Eight participants performed in-phase and anti-phase bimanual coordination patterns, a reaction time (RT) task, and several dual tasks (coordination+ RT) that manipulated attentional priority by requiring either shared attention, priority to the coordination task, or priority to the RT task. Results showed that RT was smaller for in-phase than anti-phase. Moreover, attentional manipulations led to a trade-off between pattern stability and RT performance. This suggests that performing and intentionally stabilizing a coordination pattern incur a central cost that depends on the coordination pattern's dynamic properties. Thus, this study opens a conceptual and methodological bridge between information processing and dynamic approaches to coordination.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
