Figure 2. Greater Number of Completed Sessions for the 70–30 Reward Probability Group in Both Discrimination and Reversal Learning.
Note. (A and B) Plotted are the number of subjects per session (A) and the number of sessions to criterion (B) during the discrimination (prereversal) phase. The 70–30 reward probability group completes significantly more sessions during discrimination than the 90–30 group. (C and D) The same as (A) and (B) but during reversal learning. The 70–30 reward probability group again completes significantly more sessions than the 90–30 group. Bars indicate ±SEM.
