Detailed comparisons.

<p><b>A.</b> A comparison of time allocation in the training session with the experimental session. We plotted the proportion of time subjects allocated to the first movement in the experimental session against that in the training session. If were similar between the experimental and the training session, most points would fall symmetrically about the diagonal line. Colors were used to code for the reward conditions (blue: equal-reward condition; red: unequal-reward condition). Different symbols were used to code distance conditions (dot: equal-distance condition; cross: unequal-distance condition). <b>B.</b> The estimated probability of hitting target B (second movement) () was plotted against the mean movement time (ms) to target A (the first movement) separately for the top 25% fastest movements (in red) and for the bottom 25% movements (in green). Each data point in the graph represented a combination of reward and distance condition from a subject. The duration of the first movement had little effect on the probability of success of the second movement.
