Which technique uses a token-based 'money system' to reward behavior?

• A. Prompt
• B. Token economy
• C. Modeling
• D. Contingency contracting

Answer: (B)

Reinforcement systems that use a token-based currency to reinforce behavior. In a token economy, individuals earn tokens for displaying target behaviors, and those tokens can later be exchanged for backup reinforcers such as activities, treats, or privileges. The tokens function as secondary reinforcers, making motivation for desirable behaviors more durable across time because the rewards are earned and saved rather than given immediately every time. This setup is especially common in classrooms and therapeutic settings to shape and maintain behavior with a clear, observable link between actions and rewards.

Other techniques involve different mechanisms: a prompt is a cue that helps someone respond correctly, modeling is about observing someone perform the behavior, and contingency contracting is a formal written agreement outlining rewards or punishments tied to specific performance. These do not rely on a token-based monetary system as the primary means of reinforcement.
