本文涉及使用跟踪研究，以测试的理论帐户的信息处理过程中进行的人类中枢神经系统的运动控制。该理论为反应时研究和连续跟踪研究提供了一座桥梁。有人提出，人类中枢神经系统包括神经元电路计算逆的内部模型的多输入，多输出，动态，非线性的关系，传出的电机命令和它们所产生的感知后果。在运动执行期间采用逆内部模型来将期望的感知结果的预先计划的轨迹转换成适当的传出电机命令以实现它们。CNS需要有限的时间间隔来预先计划运动的期望感知结果，并且在完成旧运动的计划之前，它不会开始计划新的运动。这种行为将不确定性引入到运动规划中。在本文中，我们表明，增益和相位的频率响应特性的人类操作员在视觉追踪跟踪任务可以从理论上推导出这些假设。通过将内部模型的不准确性和性能的速度-精度权衡的影响，它表明，实验测量的跟踪行为的各个方面可以占。
This paper concerns the use of tracking studies to test a theoretical account of the information processing performed by the human CNS during control of movement. The theory provides a bridge between studies of reaction time and continuous tracking. It is proposed that the human CNS includes neuronal circuitry to compute inverse internal models of the multiple input, multiple output, dynamic, nonlinear relationships between outgoing motor commands and their resulting perceptual consequences. The inverse internal models are employed during movement execution to transform preplanned trajectories of desired perceptual consequences into appropriate outgoing motor commands to achieve them. A finite interval of time is required by the CNS to preplan the desired perceptual consequences of a movement and it does not commence planning a new movement until planning of the old one has been completed. This behavior introduces intermittency into the planning of movements. In this paper we show that the gain and phase frequency response characteristics of the human operator in a visual pursuit tracking task can be derived theoretically from these assumptions. By incorporating the effects of internal model inaccuracy and of speed-accuracy trade-off in performance, it is shown that various aspects of experimentally measured tracking behavior can be accounted for.
