Answer:
The correct answer is A fixed interval reinforcement schedule.
Explanation:
Fixed interval: The reinforcement appears every time a certain amount of time elapses, provided that during the interval the response has been given. An example would be that of a father who verifies every half hour that his son is studying, and when so he makes a compliment. Fixed interval problems produce an unequal response rate. Once the booster is administered, the response rate tends to be low. During the interval, the behavior typically increases to a high level immediately before the next scheduled booster. The overall number of responses in a fixed interval program is moderate.
