Figure 2

Temporal-duration discrimination performance by a simulated observer in Simulation 1 that performed as illustrated in Figure 1. Details of the simulation are described in the text. The horizontal axis indicates the objective duration of the trial (Levels 1–35 Short; Levels 37–71 Long). The open diamonds and open triangles, respectively, show the proportion correct the observer achieved on the trials it chose to complete or was forced to complete. The filled circles show the proportional use of the uncertainty response for different trial levels.
