Strategies for all subjects and all trials displayed in the 2D <i>result space</i>.

<p>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 <i>Mutual Information</i> and lower <i>Mean Squared Force</i>; however, the majority of trials converged to areas with higher <i>Mutual Information</i> and lower <i>Sensitivity</i>. 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 <i>result space</i>. None of the subjects moved toward the minimum force strategy.
