Abstract

Previous studies have suggested that deafness could lead to deficits in motor skills and other body-related abilities. However, the literature regarding motor skills in deaf adults is scarce and existing studies often included participants with heterogeneous language backgrounds and deafness etiologies, thus making it difficult to delineate the effects of deafness. In this study, we investigated motor learning in deaf native signers and hearing nonsigners. To isolate the effects of deafness and those of acquiring a signed language, we additionally tested a group of hearing native signers. Two well-established paradigms of motor learning were employed, in which participants had to adapt their hand movements to a rotation of the visual feedback (Experiment 1) or to the introduction of a force field (Experiment 2). Proprioceptive estimates were assessed before and after adaptation. Like hearing nonsigners, deaf and hearing signers showed robust adaptation in both motor adaptation paradigms. No significant differences in motor adaptation and memory were observed between deaf signers and hearing nonsigners, as well as between hearing signers and hearing nonsigners. Moreover, no discernible group differences in proprioceptive accuracy were observed. These findings challenge the prevalent notion that deafness leads to deficits in motor skills and other body-related abilities.

聋人和听力母语手语者的运动适应。
以往的研究表明,耳聋可能会导致运动技能和其他身体相关能力的缺陷。然而,有关成年聋人运动技能的文献很少,而且现有的研究通常包括具有不同语言背景和耳聋病因的参与者,因此很难界定耳聋的影响。在这项研究中,我们调查了母语为手语的聋人和听力非手语者的运动学习情况。为了区分耳聋的影响和习得手语的影响,我们还对一组听力正常的本地手语者进行了测试。我们采用了两种行之有效的运动学习范式,让参与者根据视觉反馈的旋转(实验 1)或力场的引入(实验 2)来调整他们的手部动作。在适应之前和适应之后,都要对感觉估计进行评估。与有听力的非手语者一样,聋人和有听力的手语者在两种运动适应范式中都表现出很强的适应能力。在运动适应和记忆方面,聋人手语者和非听力手语者之间以及听力手语者和非听力手语者之间没有发现明显的差异。此外,在本体感觉的准确性方面也没有发现明显的群体差异。这些研究结果对普遍认为耳聋会导致运动技能和其他身体相关能力缺陷的观点提出了质疑。
