Rates of target-key responding for baseline and prefeeding test sessions (left panel) and for baseline (at 0 on the x-axis) and extinction test sessions in three-component multiple concurrent VI VI schedules (right panel; from Nevin et al., 1990, Exp. 2). During baseline training, the target response obtained 15 reinforcers/hr in Components A and B, and an alternative response obtained 45 reinforcers/hr concurrently in Component A only. In Component C, the target response obtained 60 reinforcers/hr). Note that the order of response rates for Components A and B reversed during the tests.
