Abstract

There is debate about how implicit and explicit processes interact in sensorimotor adaptation, implicating how error signals drive learning. Target error information is thought to primarily influence explicit processes, therefore manipulations to the veracity of this information should impact adaptation but not implicit recalibration (i.e. after-effects). Thirty participants across three groups initially adapted to rotated cursor feedback. Then we manipulated numeric target error through knowledge of results (KR) feedback, where groups practised with correct or incorrect (+/-15°) numeric KR. Participants adapted to erroneous KR, but only the KR + 15 group showed augmented implicit recalibration, evidenced by larger after-effects than before KR exposure. In the presence of sensory prediction errors, target errors modulated after-effects, suggesting an interaction between implicit and explicit processes.

通过错误数值反馈的内隐适应过程的更新。
关于内隐和外显过程如何在感觉运动适应中相互作用,暗示错误信号如何驱动学习,存在争议。目标误差信息被认为主要影响显性过程,因此对该信息准确性的操纵应影响适应,但不影响隐含的重新校准(即后效)。分成三组的30名参与者最初适应了光标旋转的反馈。然后,我们通过结果知识(KR)反馈来操纵数字目标误差,在这些组中,使用正确或不正确的(+/-15°)数字KR进行练习。参与者适应了错误的KR,但只有KR + 15组表现出增强的隐性重新校准,这可以通过比KR暴露前更大的后效应来证明。在存在感官预测误差的情况下,目标误差调节了后效,表明内隐过程和外显过程之间存在相互作用。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
