Abstract
After responding was maintained on multiple variable-interval schedules of reinforcement, a limited-hold requirement was added to one component. Each scheduled availability of reinforcement terminated if no response occurred within a 1-sec period of time. Response rate increased and reinforcement rate decreased in the limited-hold component. Response rate in the unchanged VI component increased. When responding was extinguished in the changed component, positive behavioral contrast was observed in the unchanged VI component.
