摘要

结合动作观察和运动想象(AO+MI)可以改善健康成年人和某些患者的运动执行力(ME)。然而,目前还不清楚 AO+MI 过程中观察部分的特异性如何影响 ME。由于泛化观察可使 AO+MI 康复计划更加灵活,本研究调查了在 AO+MI 过程中观察目标单词(特定条件)或非匹配单词(泛化条件)的键入是否会对健康青壮年的键盘键入产生不同的影响。在实验 1 中,51 名学生一边观看打字视频,一边想象输入目标单词,这些视频要么是目标单词的特定视频,要么是一般视频。在 "AO+MI "条件下,学生的键入速度没有差异,但在 "AO+MI "条件下,学生的键入速度比没有观察或想象的要慢。实验 2 在 20 名学生中重复了实验 1,但在 AO+MI 条件下,刺激速度更快,而在对照条件下,认知难度增加。结果表明,AO+MI 后打字速度变慢可能是由于意象和执行之间的任务切换以及自动模仿效应的强烈影响。这两项实验都证明,一般和特定的 AO+MI 对 ME 的影响相当。此外,AO+MI 和一项具有挑战性的认知任务之后的 ME 速度都较慢,这为 MI 的运动认知模型提供了支持。

Stimulus specificity in combined action observation and motor imagery of typing.

Combined action observation and motor imagery (AO + MI) can improve movement execution (ME) in healthy adults and certain patient populations. However, it is unclear how the specificity of the observation component during AO + MI influences ME. As generalised observation could result in more flexible AO + MI rehabilitation programmes, this study investigated whether observing typing of target words (specific condition) or non-matching words (general condition) during AO + MI would have different effects on keyboard typing in healthy young adults. In Experiment 1, 51 students imagined typing a target word while watching typing videos that were either specific to the target word or general. There were no differences in typing execution between AO + MI conditions, though participants typed more slowly after both AO + MI conditions compared with no observation or imagery. Experiment 2 repeated Experiment 1 in 20 students, but with a faster stimulus speed in the AO + MI conditions and increased cognitive difficulty in the control condition. The results showed that the slowed typing after AO + MI was likely due to a strong influence of task-switching between imagery and execution, as well as an automatic imitation effect. Both experiments demonstrate that general and specific AO + MI comparably affect ME. In addition, slower ME following both AO + MI and a challenging cognitive task provides support for the motor-cognitive model of MI.

期刊介绍: Promoting the interests of scientific psychology and its researchers, QJEP, the journal of the Experimental Psychology Society, is a leading journal with a long-standing tradition of publishing cutting-edge research. Several articles have become classic papers in the fields of attention, perception, learning, memory, language, and reasoning. The journal publishes original articles on any topic within the field of experimental psychology (including comparative research). These include substantial experimental reports, review papers, rapid communications (reporting novel techniques or ground breaking results), comments (on articles previously published in QJEP or on issues of general interest to experimental psychologists), and book reviews. Experimental results are welcomed from all relevant techniques, including behavioural testing, brain imaging and computational modelling. QJEP offers a competitive publication time-scale. Accepted Rapid Communications have priority in the publication cycle and usually appear in print within three months. We aim to publish all accepted (but uncorrected) articles online within seven days. Our Latest Articles page offers immediate publication of articles upon reaching their final form. The journal offers an open access option called Open Select, enabling authors to meet funder requirements to make their article free to read online for all in perpetuity. Authors also benefit from a broad and diverse subscription base that delivers the journal contents to a world-wide readership. Together these features ensure that the journal offers authors the opportunity to raise the visibility of their work to a global audience.
