Detection probability in closed-loop, replay, and fixed sessions. Data obtained from an experiment on one individual (left column) and the summation of observations from the eight different subjects that were tested in this protocol (right column). In all cases, the fluctuations around mean detection probability are significantly smaller in the closed-loop session. The initial decline in detection probability, which is most apparent in the closed-loop and replay sessions, reflects the initial setting of both ${\tilde{P}}_n$ and C_n to 0.5. Error bars in the righthand column depict SD across all subjects.
