A group contingency is a behavior management protocol where a single consequence (it can be a reward or aversive) is given based on either the behavior of an individual in a group, the behavior of a particular set of people within the group or the group as a whole. The entire group receives the consequence. This type of behavior management leverages peer pressure and peer monitoring.
Independent group contingency: The contingency is presented to all but earned by only those who meet the criterion.
Dependent group contingency: The reward for the whole group is based on the performance of either an individual or collection of individuals within the group. Can be called the hero procedure when an individual earns a reward for the whole group.
Interdependent group contingency: All members of the group must meet criterion before any member receives the consequence. This is the “all or none” procedure. The consequence can be delivered based on one of several ways:
PLACHECK (planned activity check) is a recording method on a group behavior and the observer headcounts the number of people engaging in a target behavior at the end of each interval. For example, a teacher can count the number of children actively reading a book during “quiet” time.
