摘要

本研究考察了单任务或双任务练习后,运动序列表征在不同时间点的注意需求。视觉空间表征根据目标位置等视觉空间坐标对运动进行编码。运动表象则根据运动坐标对运动进行编码,包括关节角度和肌肉激活模式。参与者被随机分配到单任务或双任务练习组。习得后,参与者分别在双任务和单任务下进行了两次保持测试和动作间转移测试。转移测试包括镜像测试和非镜像测试,考察了运动和视觉空间表征的发展。主要发现是序列表征的注意力需求不受练习条件的影响。然而,在这两种表征中,运动开始比运动结束需要更多的注意力。

Dual-Task and Single-Task Practice Does Not Influence the Attentional Demands of Movement Sequence Representations.

This study examined the attentional demands of movement sequence representations at different temporal points after single- or dual-task practice. The visual-spatial representation encodes the movement based on visual-spatial coordinates such as the target locations. The motor representation encodes the movement in motor coordinates including joint angles and muscle activation patterns. Participants were randomly assigned to a single-task or dual-task practice group. Following acquisition, participants performed two retention tests and inter-manual transfer tests, both under dual-task and single-task. The transfer tests consisted of a mirror and non-mirror test and examined motor and visual-spatial representation development. The main finding is that attentional demands of the sequence representations were not affected by the practice condition. However, movement initiation requires more attention than the end of the movement in both representations.

期刊介绍: The Journal of Motor Behavior, a multidisciplinary journal of movement neuroscience, publishes articles that contribute to a basic understanding of motor control. Articles from different disciplinary perspectives and levels of analysis are encouraged, including neurophysiological, biomechanical, electrophysiological, psychological, mathematical and physical, and clinical approaches. Applied studies are acceptable only to the extent that they provide a significant contribution to a basic issue in motor control. Of special interest to the journal are those articles that attempt to bridge insights from different disciplinary perspectives to infer processes underlying motor control. Those approaches may embrace postural, locomotive, and manipulative aspects of motor functions, as well as coordination of speech articulators and eye movements. Articles dealing with analytical techniques and mathematical modeling are welcome.
