An entire class earns extra recess if one randomly selected student's homework meets criterion. Which arrangement is this?
- AToken economy
- BIndependent group contingency
- CInterdependent group contingency
- DDependent group contingency
Show answer and rationale
Correct: D. In a dependent group contingency the group's access to reinforcement depends on the performance of one individual or a small subset. Independent arrangements deliver reinforcement per individual performance, and interdependent arrangements require the whole group to meet a criterion.
- B — Independent contingencies reinforce each student on their own performance.
- C — Interdependent contingencies require the group as a whole to meet a criterion.
- A — A token economy is a reinforcement system, not a group arrangement.
