A device schedules administration of reinforcing rewards consistent with a psychological behavior modification program. The instructions to grant rewards are randomized in response to the subject successfully executing targeted behavior thus making the reinforcement unpredictable to the individual being treated. The device has a base with an indicating surface on which code marks are placed in predetermined locations. The code marks are encoded with respect to instructions to grant or deny a reinforcement. The device also has an opaque mask coextensive with the indicating surface. The mask includes an aperture with an initially closed cover to conceal the code marks from view of the individual. At appropriate time, the cover is opened to reveal the code mark so that the individual can follow instructions whether or not to receive a reward. The device is light weight, portable, convenient to carry and easy to use by the individual.
