这篇文章提出了一个有争议的问题：最优控制理论对理解运动行为有用还是误导？随着人们开始将运动控制和感知的内部模型混为一谈，这个问题变得越来越尖锐（Poeppel et al., 2008; Hickok et al., 2011）。然而，运动控制中的正演模型并不是感知推理中使用的生成模型。这个视角试图突出运动控制和感知内部模型之间的差异，并询问最优控制是否是思考事物的正确方式。这里考虑的问题可能对最优决策理论和贝叶斯学习和行为方法有更广泛的影响。
This article poses a controversial question: is optimal control theory useful for understanding motor behavior or is it a misdirection? This question is becoming acute as people start to conflate internal models in motor control and perception (Poeppel et al., 2008; Hickok et al., 2011). However, the forward models in motor control are not the generative models used in perceptual inference. This Perspective tries to highlight the differences between internal models in motor control and perception and asks whether optimal control is the right way to think about things. The issues considered here may have broader implications for optimal decision theory and Bayesian approaches to learning and behavior in general.
