Punishment seems to increase the variability of the behavior.

• A. Increase variability
• B. Decrease variability
• C. No effect
• D. Guaranteed elimination

Answer: (A)

Punishment tends to drive the learner to try different ways to avoid the aversive consequence or to obtain reinforcement, which increases the variety of forms the behavior can take. When a specific response is punished, the animal preserves the goal (getting out of the punishing situation or achieving a payoff) but experiments with other topographies to accomplish it, leading to more variable behavior. For example, if a dog is punished for pulling on the leash, it may start walking with different paces, stopping, circling, or switching to alternative cues or routes as it searches for a way to avoid the correction. This exploration shows up as greater variability in how the response is displayed.

In contrast, this variability isn’t typically reduced or eliminated by punishment alone, and it doesn’t guarantee elimination of the behavior. Reinforcement and shaping for a precise, desired topography tend to produce more consistent, less variable responses.
