Skilled motor control of an inverted pendulum implies low entropy of states but high entropy of actions

(a) Utility Ui of trials i during the balancing task plotted as a function of H(Ai|Si) for all participants and pendulum lengths L. Larger values of utility Ui correspond to better performance in balancing the pendulum. Spearman correlation ρ = 0.944; Pearson correlation r = 0.967. In (b) the trials are separated by pendulum length in different subplots.
