What is a major drawback of the Premack Principle?

• A. It cannot be applied to any dog and only works with cats.
• B. The higher-probability reinforcer is sometimes hard to control.
• C. It always requires punishment.
• D. It only works with edible reinforcers.

Answer: (B)

The approach hinges on using a high-probability behavior as a reward for a lower-probability one. The major drawback is that the higher-probability reinforcer is sometimes hard to control. In real training, what the dog wants most and how readily they can access it isn’t always predictable. If the preferred activity is easy to obtain outside of training or isn’t reliably withheld until the target behavior occurs, the contingency falls apart and the reinforcement loses its effectiveness. Factors like the environment, time of day, hunger or arousal, and the dog's current motivation can all shift the value or availability of that reinforcer. Because of that variability, the Premack setup can become less reliable, especially in busy, real-world settings. To use it effectively, choose a high-probability reinforcer you can tightly control and ensure access is clearly contingent on the desired behavior.
