Which of the following is an example of positive reinforcement?

• A. Giving a sticker for a good test score
• B. Removing an assignment because the class did well
• C. Giving a police speeding ticket
• D. Grounding a student for misbehavior

Answer: (A)

Positive reinforcement adds something pleasant after a behavior to increase how likely that behavior is to happen again. Giving a sticker for a good test score does exactly that: the sticker is a rewarding, enjoyable consequence added right after the student earns a good score, which encourages continued effort to achieve similar results.

The other options involve removing something or presenting a consequence meant to deter behavior, not to increase the desired behavior. Removing an assignment reduces pressure and is a form of negative reinforcement or a concession, while a speeding ticket and grounding are punishments that aim to decrease misbehavior rather than reinforce positive performance.
