Final answer:
The compound schedule in question is a multiple schedule of reinforcement, where two or more independent schedules occur without an SD for each. A fixed interval schedule rewards behavior at set times, while a fixed ratio schedule requires a certain number of responses for a reward.
Step-by-step explanation:
The compound schedule being described is the multiple schedule of reinforcement, which involves two or more basic schedule requirements that occur successively in any order. In this case, the question is referring to schedules that do not have a specific discriminative stimulus (SD) for each independent schedule.
A fixed interval reinforcement schedule is when a behavior is rewarded after a set amount of time, regardless of how many times the behavior occurs within that interval. An example would be a patient who receives pain relief medication through an IV drip at fixed time intervals, such as one dose per hour. This is in contrast to a fixed ratio reinforcement schedule, where a set number of responses must occur before a behavior is rewarded.
Higher-order conditioning, also known as second-order conditioning, involves using a conditioned stimulus to condition a neutral stimulus.
