A stimulus that functions as a reinforcer because of prior pairing with other reinforcers is called what?

• A. Conditioned Reinforcer
• B. Unconditioned Reinforcer
• C. Conditioned Punisher
• D. Conditioned Stimulus

Answer: (A)

The main idea is conditioned reinforcement: a stimulus becomes reinforcing because it has been paired with other reinforcers. This learned reinforcer is also called a secondary reinforcer. It gains value through association with primary reinforcers (like food, water, warmth) and can strengthen behavior even when the primary reinforcer isn’t present. For example, praise or money doesn’t satisfy a basic need by themselves, but they reliably reinforce behavior because they’ve been paired with those primary rewards.

By comparison, a primary (unconditioned) reinforcer is naturally reinforcing, such as food or water. A conditioned punisher is a stimulus that reduces behavior after being paired with punishers. A conditioned stimulus is a neutral cue that, after pairing with an unconditioned stimulus, starts to elicit a learned response. The described scenario fits conditioned reinforcement most precisely.
