The purpose of this research is to evaluate the effects of extrinsic reinforcement on intrinsically reinforced behaviors in relation to the overjustification effect, which states that the delivery of extrinsic reinforcement may reduce intrinsically reinforced behavior. Two experiments were conducted using 3 typically developing participants in each. Experiment 1 evaluated the effects of expected and unexpected reinforcers on play behavior during extinction while Experiment 2 replicated the procedures used in Experiment 1 with academic activities. Both experiments employed a multielement, multiple baseline across participants design. Results from both experiments indicate that the overjustification effect did not occur and there is no differentiation between expected and unexpected reinforcers. These results extend the existing literature on the overjustification effect by providing analyses at the individual level using time series methodology. More specifically we were able to evaluate trend, variability, and potential behavioral processes as they relate to responding during reinforcement as well as subsequent extinction conditions. Responding during baseline was variable. When reinforcement was implemented, responding increased and variability was reduced. Subsequently, during extinction, responding remained high for a majority of the participants and stabilized at levels above baseline for all participants. These results suggest an additive effect of providing extrinsic reinforcement contingent on a response that is already intrinsically motivated. Moreover, because responding remained at or above baseline levels during extinction (i.e., the overjustification effect was not observed), one cannot speak to the behavioral processes involved in such an effect.Subjects--Topical Terms:
