Final answer:
The restaurant is using a fixed interval reinforcement schedule, rewarding customers with a free child's meal for every adult meal purchased every Monday. This predictable reward schedule encourages customers to visit the restaurant on Mondays.
Step-by-step explanation:
The restaurant operates on a fixed interval reinforcement schedule. In behavioral psychology, a reinforcement schedule is used to establish predictable patterns of behavior. In this context, the restaurant provides a reward - a free child's meal - at regular, predictable intervals - every Monday. The reward happens only when a condition is met - the purchase of one adult meal. This ensures that customers reinforce the desired behavior, which is visiting the restaurant and purchasing an adult meal on Mondays.
