我们研究了适应非线性转换的能力，这种转换允许人们控制外部系统，如机器和工具。早期的研究（Verwey和Heuer 2007）表明，在只有终端反馈的情况下，参与者会发展出这种转换的内部模型，该模型在相对早期的处理水平（在振幅规范之前或在振幅规范时）运行。在本研究中，我们考察了连续视觉反馈练习后内部模型的操作水平。参与者执行快速瞄准动作，在计算机屏幕上看到的目标振幅与数字化平板电脑上所需的手的运动振幅之间存在非线性关系。参与者通过开发内部模型来适应外部转变。尽管有持续的反馈，明确的转换意识并没有发展，内部模型仍然在与终端反馈相同的早期处理水平上运行。因此，对于快速瞄准运动，反馈类型可能与内部模型的操作轨迹无关。
We investigated the ability to adjust to nonlinear transformations that allow people to control external systems like machines and tools. Earlier research (Verwey and Heuer 2007) showed that in the presence of just terminal feedback participants develop an internal model of such transformations that operates at a relatively early processing level (before or at amplitude specification). In this study, we investigated the level of operation of the internal model after practicing with continuous visual feedback. Participants executed rapid aiming movements, for which a nonlinear relationship existed between the target amplitude seen on the computer screen and the required movement amplitude of the hand on a digitizing tablet. Participants adjusted to the external transformation by developing an internal model. Despite continuous feedback, explicit awareness of the transformation did not develop and the internal model still operated at the same early processing level as with terminal feedback. Thus with rapid aiming movements, the type of feedback may not matter for the locus of operation of the internal model.
