Scientists have determined which characteristics of an arm movement influence the subjective effort associated with this movement. They found that duration, biomechanics and force had an influence on the effort, while movement amplitudes had no effect. Their results shed light on a postulated link between two important functions of the brain: optimizing action selection in decision-making and in movement execution.
