Final answer:
Conditioned reinforcers are known as secondary reinforcers, which are not inherently valuable but become reinforcing through their association with primary reinforcers.
Step-by-step explanation:
Conditioned reinforcers are also known as secondary reinforcers. They differ from primary reinforcers, which include necessities like food, water, and sleep that have innate reinforcing qualities. Secondary reinforcers have no inherent value but become reinforcing when they are associated with a primary reinforcer. For example, praise becomes reinforcing when it is linked with affection, a primary reinforcer. In operant conditioning, secondary reinforcers are important because they can be used to modify behavior by being paired with primary reinforcers.
