What is reinforcement?

• A. A neutral event
• B. A cue
• C. The consequence that encourages or strengthens a desired behavior
• D. A punishment

Answer: (C)

Reinforcement is the consequence that encourages or strengthens a desired behavior by making it more likely to occur again. In training a military working dog, this is usually positive reinforcement—giving a reward, praise, a toy, or a short play session immediately after the dog performs the desired action. The crucial parts are timing and consistency: reward right after the behavior so the dog makes a clear link between what it did and the positive outcome. This strengthens the behavior and increases the chance it will be repeated in the future.

It’s different from a cue, which is merely the signal that a behavior should occur, and from punishment, which aims to lessen a behavior. A simple example: after the dog sits on command, you praise and reward instantly; the dog learns that sitting when asked leads to something good, so it’s more likely to sit again next time. In practice, reinforcement can be varied (switching rewards or using intermittent reinforcement later) to maintain the behavior, but the core idea remains: reinforcement is the consequence that strengthens desired behavior.
