In this type of interlocking, other reinforcement contingencies are involved directly in the selection of cultural practices, so it is important to understand the role of these contingencies in the maintenance of the behavior of the individuals which participate in the interlock. When, for example, a teacher designates a pupil as a class monitor, this pupil is responsible for maintaining the interlocking behavioral contingencies within the class, while the monitor's behavior may be maintained by consequences that are external to the individuals participating in the specific interlock, in this case, by accruing bonus points for the course.
