Answer: d. Response cost is easier to implement in a token economy.
Your answer
Step-by-step explanation:
A token economy is an economy that rewards good behavior with token and which the tokens can be exchanged for something else. Tokens could actually be chip, coin, star or what students can exchange for what they want to buy. The tokens are collected first then exchanged for meaningful items later. In a token economy, response cost is not easy to implement based on how the system is built.
