本研究探讨了在实践过程中的视觉反馈的类型的影响，一个复杂的视觉运动变换的滑动双侧杠杆上收购的内部模型的转换。三组参与者，谁练习不同类型的视觉反馈，进行了比较方面的运动准确性，曲率和运动时间。一组在练习过程中有连续的视觉反馈，两组呈现终端视觉反馈，要么只有运动的结束位置，要么结束位置连同光标的轨迹。结果表明，连续的视觉反馈导致更精确的运动结束时的位置比终端视觉反馈的实践，但不精确的运动在开环测试。这一发现表明，终端视觉反馈支持一个精确的内部模型的一个新的视觉运动转换的发展。然而，即使是在实践中的光标轨迹的终端反馈没有导致内部模型，其中包括适当的手部运动的曲率。相关性陈述：本文介绍了视觉反馈类型对学习控制滑动杠杆的复杂运动技能的影响的结果。这些研究结果有助于优化培训程序的概念基础，以获得掌握微创手术中使用的器械所需的感觉运动技能。
This study investigated the influence of the type of visual feedback during practice with a complex visuo-motor transformation of a sliding two-sided lever on the acquisition of an internal model of the transformation. Three groups of participants, who practised with different types of visual feedback, were compared with regard to movement accuracy, curvature and movement time. One group had continuous visual feedback during practice and two groups were presented terminal visual feedback, either only the end position of the movement or the end position together with the trajectory of the cursor. Results showed that continuous visual feedback led to more precise movement end positions during practice than terminal visual feedback, but to less precise movements during open-loop tests. This finding indicates that terminal visual feedback supports the development of a precise internal model of a new visuo-motor transformation. However, even terminal feedback of the cursor trajectory during practice did not result in an internal model, which includes appropriate curvatures of hand movements. Statement of Relevance:This paper presents results on the influence of type of visual feedback on learning the complex motor skill of controlling a sliding lever. These findings contribute to the conceptual basis of optimised training procedures for the acquisition of sensori-motor skills required for the mastery of instruments utilised in minimally invasive surgery.
