Abstract

Although motor imagery and working memory (WM) appear to be closely linked, no previous studies have demonstrated direct evidence for the relationship between motor imagery and WM abilities. This study investigated the association between WM and gait motor imagery and focused on the individual differences in young adults. This study included 33 participants (mean age: 22.2 ± 0.9 years). We used two methods to measure the ability of different WM domains: verbal and visuo-spatial WM. Gait motor imagery accuracy was assessed via the mental chronometry paradigm. We measured the times participants took to complete an actual and imagined walk along a 5 m walkway, with three different path widths. The linear mixed effects model analysis revealed that visuo-spatial WM ability was a significant predictor of the accuracy of gait motor imagery, but not of verbal WM ability. Specifically, individuals with lower visuo-spatial WM ability demonstrated more inaccuracies in the difficult path-width conditions. However, gait motor imagery was not as accurate as actual walking even in the easiest path width or in participants with high visuo-spatial WM ability. Further, visuo-spatial WM ability was significantly correlated with mental walking but not with actual walking. These results suggest that visuo-spatial WM is related to motor imagery rather than actual movement.

视觉空间工作记忆与步态运动想象之间的关联

虽然运动想象和工作记忆（WM）似乎密切相关，但之前的研究并未直接证明运动想象和 WM 能力之间的关系。本研究调查了 WM 与步态运动想象之间的关系，并重点研究了年轻人的个体差异。本研究包括 33 名参与者（平均年龄：22.2 ± 0.9 岁）。我们采用了两种方法来测量不同WM领域的能力：言语WM和视觉空间WM。步态运动想象的准确性通过心理计时范式进行评估。我们测量了参与者在5米长的人行道上完成实际行走和想象行走所需的时间，人行道有三种不同的宽度。线性混合效应模型分析表明，视觉空间WM能力是步态运动想象准确性的重要预测因素，而语言WM能力则不是。具体来说，视觉空间 WM 能力较低的人在困难的路径宽度条件下表现出更多的不准确性。然而，即使是在最容易的路径宽度条件下，步态运动想象也不如实际行走准确。此外，视觉空间 WM 能力与心理行走显著相关，但与实际行走无关。这些结果表明，视觉空间 WM 与运动想象而非实际运动有关。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
