The Premack principle states that any Response A can reinforce any other Response B if the independent rate of A is greater than the independent rate of B (Premack, 1959). Applying the Premack principle involves arranging the environment to restrict access to certain responses based on relative probabilities of a set of given responses (Timberlake & Farmer-Dougan, 1991). Practitioners may apply the Premack principle when arranging contingencies, such as first -- then statements. Though there is literature to support that arranging contingencies based on the Premack principle can increase engagement in low probability responses, further evaluation is needed to examine the impact these contingencies have on other behaviors. The present stud evaluates the impact of arranging activity schedules according to the Premack principle on on-task behavior, challenging behavior, and correct responding. Results suggest that there is no differentiation on these other behaviors when arranging contingencies according to the Premack principle when compared to other arrangements.
