On the basis of computational studies it has been proposed that the central nervous system internally simulates the dynamic behavior of the motor system in planning, control, and learning; the existence and use of such an internal model is still under debate. A sensorimotor integration task was investigated in which participants estimated the location of one of their hands at the end of movements made in the dark and under externally imposed forces. The temporal propagation of errors in this task was analyzed within the theoretical framework of optimal state estimation. These results provide direct support for the existence of an internal model.
基于计算研究，有人提出中枢神经系统在规划、控制和学习过程中会在内部模拟运动系统的动态行为；这种内部模型的存在和用途仍在争论之中。研究了一项感觉运动整合任务，参与者在黑暗中且在外部施加力的情况下进行运动后，估计其一只手的位置。在最优状态估计的理论框架内分析了该任务中误差的时间传播。这些结果为内部模型的存在提供了直接支持。
