When teaching a new behavior, which reinforcement schedule is most effective?

• A. Fixed interval reinforcement
• B. Continuous reinforcement
• C. Variable ratio reinforcement
• D. Differential reinforcement of low rates

Answer: (B)

When a dog is learning a brand-new behavior, you want immediate, consistent feedback for every correct response. This is what continuous reinforcement provides: you reinforce the desired behavior every time it occurs, creating a clear, repeatable link between the action and the reward. That steady feedback speeds up acquisition and helps the dog understand exactly what is being asked, which is especially important when you’re shaping a new skill.

Once the behavior is reliably performed, you can shift to intermittent reinforcement to maintain it and make it more resistant to extinction. The other schedules aren’t as effective for initial learning: fixed interval reinforcement rewards after a fixed time regardless of behavior, which slows learning; variable ratio reinforcement reinforces after a changing number of responses, which supports high, persistent responding but doesn’t give the steady feedback needed during early learning; and differential reinforcement of low rates focuses on reducing a behavior rather than teaching a new one.
