A major drawback of the Premack Principle is that if the less-desirable behavior is aversive, it can create negative associations with the more desirable behavior.

• A. It can always lead to immediate and perfect learning.
• B. If the less-desirable behavior is aversive, it can create negative associations with the more desirable behavior.
• C. It only works with food rewards.
• D. It never applies to social rewards.

Answer: (B)

The Premack Principle uses a behavior the animal tends to perform readily as a reinforcer for a behavior it is less likely to perform. The major drawback here is that if the less-desirable behavior is aversive, the animal may come to associate the desirable, rewarded activity with that unpleasant experience. The result can be avoidance or negative feelings toward the desirable behavior or the situation, which undermines the effectiveness of using the higher-probability activity as a reward.

It’s not about guaranteed instant learning, nor is it limited to food rewards; it can involve social rewards as well. In practice, the potential for aversive pairing means trainers should avoid pairing truly aversive tasks with rewards and ensure the less-desirable behavior isn’t inherently distressing, to keep the desired behavior positively reinforced.
