The objective of the experiment was to assess the change in attentional demands of a movement sequence guided by visual-spatial and motor representations across practice sessions in a dual-task probe paradigm. Participants were randomly assigned to either a 1-day or 2-day practice group. Following acquisition of the motor sequence task, participants first conducted a retention test and then four inter-manual transfer tests under single and dual-task conditions. The probe task was a simple reaction time. The inter-manual transfer tests, consisting of a mirror and non-mirror test, examined the development of the motor and visual-spatial representation, respectively. The results indicated that both representations guided the movement sequence and required attention. The attentional demands did not change with additional practice.
实验的目的是评估在双任务探测范式中，通过视觉空间和运动表现引导的运动序列在练习阶段注意力需求的变化。参与者被随机分配到 1 天或 2 天的练习组。在获得运动序列任务后，参与者首先进行保留测试，然后在单任务和双任务条件下进行四次手动转移测试。探测任务是一个简单的反应时间。手动转移测试包括镜像和非镜像测试，分别检查运动和视觉空间表现的发展。结果表明，两种表现都指导了运动序列，并需要注意力。随着额外的练习，注意力需求并没有改变。
