How effort is internally quantified and how it influences both movement generation and decisions between potential movements are 2 difficult questions to answer. Physical costs are known to influence motor control and decision-making, yet we lack a general, principled characterization of how the perception of effort operates across tasks and conditions. Morel and colleagues introduce an insightful approach to that end, assessing effort indifference points and presenting a quadratic law between perceived effort and force production.

电机控制和决策方面的感知努力

内部如何量化努力，以及它如何影响运动的产生以及潜在运动之间的决定，这是两个很难回答的问题。已知物理成本会影响运动控制和决策，但是我们缺乏对工作量感知如何在任务和条件下进行操作的一般性原则性描述。莫雷尔和他的同事为此目的介绍了一种有见地的方法，评估了努力的无差异点，并提出了感知到的努力与力量产生之间的二次定律。
