Which statement identifies a primary reinforcer?

• A. A verbal praise cue that the dog has learned to associate with rewards.
• B. A clicker sound.
• C. Food or water that is innately rewarding to the animal.
• D. A correction or timeout.

Answer: (C)

Primary reinforcers are inherently rewarding because they satisfy basic biological needs. Food or water fits this perfectly in dogs—it’s rewarding without any prior learning, so it directly strengthens a behavior when delivered after that behavior. Verbal praise and a clicker, on the other hand, aren’t innately rewarding on their own; they gain their value through association with something the dog already finds rewarding (often food). A correction or timeout is a punishment, not a reinforcer, so it does not reinforce the desired behavior.
