Joe owned a small repair shop. Each day, he would check the mail to see if any of his customers mailed in a payment for the work
he had done for them. Some days, he would receive a check or two. At other times, he would have to wait days before getting another payment. What schedule of reinforcement is evident here?
In operant conditioning, a variable-interval schedule is a schedule of reinforcement where a reaction is remunerated after a capricious measure of time has passed. This timetable creates a moderate, unfaltering rate of reaction.

In this way, a variable-interval schedule implies that support is conveyed at different and erratic intervals of time.
