A stimulus used in conditioning can gain reinforcing properties if it is associated with a primary reinforcer.

• A. Negative reinforcement
• B. Extinction
• C. Secondary reinforcement
• D. Punishment

Answer: (C)

A stimulus can become reinforcing through association with a primary reinforcer. A primary reinforcer directly satisfies a biological need (like food, warmth, or safety). When a neutral cue is consistently paired with that primary reinforcer, the cue itself begins to take on reinforcing properties because it signals that a primary reward is available or coming. This learned cue is called a secondary (or conditioned) reinforcer. It can then reinforce future behavior even when the primary reinforcer isn’t present, which lets people use tokens, money, praise, or signals to shape actions. For example, money is valuable not because it directly satisfies a biological need, but because it has been repeatedly linked with obtaining such rewards. The other options describe different processes: negative reinforcement removes an aversive stimulus to increase a behavior, extinction is the loss of a learned response when reinforcement stops, and punishment aimed to decrease a behavior.
