A: Examples of simulated trajectories for continuously copying a pentagon. B: Time course of the relative desirability values of the 5 individual policies (i.e., 5 segments) in a successful trial for copying a pentagon. The line colors correspond to the segments of the pentagon as shown in the top panel. The shape was copied counterclockwise (as indicated by the arrow) starting from the gray vertex. Each of the horizontal discontinuous lines indicate the completion time of copying the current segment. Notice that the desirability of the current segment peaks immediately after the start of drawing that segment and falls down gradually, whereas the desirability of the following segment starts rising while copying the current segment. Because of that, the consecutive segments compete for action selection frequently producing error trials, as illustrated in panel C. Finally, the panels (D) and (E) depict examples of simulated trajectories for continuously copying an equilateral triangle and a square, respectively, counterclockwise starting from the bottom right vertex.
