人类适应视觉功能的空间扰动（例如，棱镜）的时间过程非常短。然而，目前还不清楚如何快速适应扰动反馈的其他方面。在本文中，我们报告的适应延迟视觉反馈。三组六名受试者跟踪不可预测的，连续移动的目标，使用手持操纵杆，而操纵杆位置的视觉反馈延迟（0毫秒，200毫秒或300毫秒）。受试者明显适应了延迟，跟踪误差显著下降，但在跟踪行为的更微妙方面的变化（如不稳定性和“脉冲响应函数”的变化）并没有得到一致的观察。我们认为，所看到的适应是一致的想法，有一个“延迟组件”在内部过程中使用的手动跟踪，提出生病的模型，如史密斯预测模型。
The time-course of human adaptation to spatial perturbations of visuomotor function (e.g, with prisms) is very short. However, it is not clear how rapid the adaptation to other aspects of perturbed feedback is. In this paper we report the adaptation to delayed visual feedback. Three groups of six subjects tracked unpredictable, continuously moving targets using a hand-held joystick while visual feedback of the joystick position was delayed (0 ms, 200 ms or 300 ms). Subjects clearly adapted to the delay, with a significant drop in tracking error, but changes in more subtle aspects of their tracking behaviour (such as changes in intermittency and their "impulse response functions") were not consistently observed. We suggest that the adaptation seen was consistent with the idea of there being a "delay component" in the internal processes used in manual tracking, as proposed ill models such as the Smith predictor model.
