Which contingency describes reinforcement for each group member that depends on that member meeting a group-wide criterion?

• A. Indirect Assessments
• B. Interdependent Group Contingency
• C. Independent Variable
• D. Instructional Setting

Answer: (B)

Focusing on group-based reinforcement, an interdependent group contingency is when each member’s reinforcement depends on the entire group meeting a shared criterion. In this setup, everyone earns reinforcement only if the whole group hits the target, so the outcome for each person is tied to the group’s collective performance. This fits the idea that reinforcement for each group member depends on meeting a group-wide criterion, because the criterion is common to and achieved by the group as a whole. This contrasts with other arrangements where reinforcement is based on an individual's own performance (independent), or where the group's reinforcement hinges on one student’s performance (dependent), or with concepts not about contingencies at all.
