The horizontal axis corresponds to the simulation variable or its average experimental estimates in each trial. The vertical axis corresponds to the simulation variable or its average experimental estimates . Each point represents the average strategy in one 45 s trial. Darker red indicates early practice and lighter red indicates late practice. The left panel shows that subjects explored regions with lower Mutual Information and lower Mean Squared Force; however, the majority of trials converged to areas with higher Mutual Information and lower Sensitivity. The right panel shows the same data separated by subject: the red arrows mark how each subject's average strategy changed from early practice (first 5 trials) to late practice (last 5 trials). All subjects increased their movement amplitude, associated with an increase in overall exerted force. The majority of subjects switched from low- to high-predictability regions in the result space. None of the subjects moved toward the minimum force strategy.
