Final answer:
Money is an example of a secondary reinforcer because its value comes from its ability to be exchanged for primary reinforcers that satisfy biological needs.
Step-by-step explanation:
The student has asked which type of reinforcer money is an example of. The correct answer to this question is that money is an example of a secondary reinforcer. A secondary reinforcer, such as money, does not have inherent value in itself but acquires its reinforcing qualities through its association with primary reinforcers. For instance, money can be used to buy necessities like food, water, and shelter, which are primary reinforcers. Therefore, the value of money is contingent on what it can be exchanged for.
In contrast, primary reinforcers are inherently valuable and do not need to be learned. They include items and conditions that are necessary for survival, such as food, water, and warmth. Unlike secondary reinforcers, primary reinforcers directly satisfy biological needs and are innately rewarding.
