Student preference for and performance in fixed- versus mixed-duration schedules.

Duration schedules of reinforcement for continuous behavior abide by several preexisting operant behavioral economic equations for reinforcer cost, otherwise known as price, and consumption. Duration schedules require behaviors to occur for a set duration of time prior to accessing reinforcement, unlike interval schedules that produce reinforcement after the first instance of a behavior after a given period. Despite extensive examples of naturally occurring duration schedules, translational research regarding duration schedules is quite limited.
