Six undergraduates participated in concurrent-choice experiment with monetary reinforcers. Each subject was exposed to a time-based analog of concurrent variable-interval variable-ratio schedule with equal time interval values. The time-based analog of variable-interval schedule arranged reinforcers throughout the session, and delivered them while the schedule was chosen. The time-based analog of variable-ratio schedule arranged and immediately delivered reinforcers only while the schedule was chosen. In the time-based analog of concurrent variable-interval variable-ratio schedule, matching theory predicts increase in time allocated to the former schedule, whereas maximization theory predicts increase in time allocated to the latter schedule. Four of six subjects developed preference for the time-based variable-ratio analog schedule. No subjects developed preference for the time-based variable-interval analog schedule. The results did not support the argument that human choice behavior is governed by matching processes and maximization is derivative of the processes.
