The purpose of the experiment was to determine the extent to which observation and the inter-trial dialogue in a dyad training protocol enhance the development of a movement sequence representation. The task was to reproduce a 1300ms spatial-temporal pattern of elbow extension/flexion movements. An inter-manual transfer design with a retention test and two effector transfer tests was used. The mirror transfer test required the same motor pattern of homologous muscle activation and a sequence of joint angles as experienced during the acquisition phase, and the non-mirror transfer test required the same visual-spatial pattern as practiced during acquisition. Participants (N=40) were randomly assigned to one of four groups (50 practice acquisition trials): a dyad training group where two participants alternated between physical and observational practice and permitting an inter-trial dialogue, a dyad training group where two participants alternated between physical practice and permitting a dialogue without observation, a dyad training group where two participants alternated between physical and observational practice without a dialogue, and an individual practice control group where one participant learned the movement sequence. The practice duration was for all participants identical. The results indicated that participants involved in the dyad training protocols with either observation and/or the inter-trial dialogue developed a motor representation of the movement sequence.

Dyad训练规程和运动序列表示法的发展。

实验的目的是确定在二重训练方案中观察和试验间对话在多大程度上增强了运动序列表示的发展。任务是重现1300ms的时空模式的肘部伸展/屈曲运动。使用了带有保留测试和两个效应子转移测试的手动转移设计。镜像转移测试需要与采集阶段所经历的相同的肌肉激活运动模式和一系列关节角度序列,而非镜像转移测试则需要与采集期间所执行的视觉空间模式相同的视觉空间模式。参与者(N = 40)被随机分配到四组中的一组(50个实践习得试验):一个dyad训练组,其中两个参与者在物理练习和观察练习之间交替进行,并允许进行对话间对话;一个dyad训练组,其中两个参与者在物理练习和交替之间进行对话,而无需观察的对话;一个dyad训练组,其中两个参与者在物理练习和观察练习之间进行交替。无需对话的观察练习和一个单独的练习对照组,其中一位参与者学习了运动顺序。所有参与者的练习时间都是相同的。结果表明,参与双联训练方案的参与者在观察和/或试验间对话中形成了运动序列的运动表现。一个dyad训练组,其中两个参与者在物理练习之间交替进行,而无需观察即可对话;一个dyad训练组,其中两个参与者在不进行对话的情况下进行物理和观察练习之间的交替;以及一个个人练习控制组,其中一个参与者学习了运动顺序。所有参与者的练习时间都是相同的。结果表明,参与双联训练方案的参与者在观察和/或试验间对话中形成了运动序列的运动表现。一个dyad训练组,其中两个参与者在物理练习之间交替进行,而无需观察即可对话;一个dyad训练组,其中两个参与者在不进行对话的情况下进行物理和观察练习之间的交替;以及一个个人练习控制组,其中一个参与者学习了运动顺序。所有参与者的练习时间都是相同的。结果表明,参与双联训练方案的参与者在观察和/或试验间对话中形成了运动序列的运动表现。所有参与者的练习时间都是相同的。结果表明,参与双联训练方案并具有观察和/或试验间对话的参与者发展了运动序列的运动表现。所有参与者的练习时间都是相同的。结果表明,参与双联训练方案的参与者在观察和/或试验间对话中形成了运动序列的运动表现。
