Figure 3

Percent of correct trials per session during baseline (BL), training (●), and retention across tasks (▲) for Participant 3. Unfilled symbols (○,△) indicate that the criterion of 8 consecutive correct responses was met. Participant 3 met the mastery criterion after 48 and 123 training trials for Tasks 1 and 3, respectively. No training was provided for Task 2 because he met the criterion during the second baseline session. During the retention tests, he met the criterion for Tasks 1 and 2, but not Task 3.
