What does positive reinforcement involve in behavioral psychology?

• A. Presenting a punishing stimulus following a desired behavior
• B. Withholding a rewarding stimulus for undesired behavior
• C. Presenting a rewarding stimulus following a desired behavior
• D. Ignoring undesired behavior to shape future behavior

Answer: (C)

Positive reinforcement in behavioral psychology refers to the process of providing a rewarding stimulus after a desired behavior is exhibited, which increases the likelihood of that behavior being repeated in the future. When an individual engages in a behavior that is followed by a positive outcome—such as praise, a treat, or any other form of reward—they learn to associate that behavior with the favorable consequence.

For instance, if a child cleans their room and is then offered a compliment or a small reward, the child is more likely to clean their room again in the future because they associate the behavior with positive feedback. This strategy is a foundational concept in operant conditioning, where behaviors are modified through reinforcement and punishment strategies to promote desirable actions.

The other options describe processes that do not constitute positive reinforcement. Presenting a punishing stimulus typically aims to decrease undesirable behavior, while withholding a reward addresses the lack of reinforcement for undesired actions. Ignoring an undesired behavior is a strategy known as extinction, which decreases that behavior over time but does not involve providing positive reinforcement for a desirable behavior. In contrast, option C directly aligns with the principles of operant conditioning that emphasize the enhancement of behaviors through positive outcomes.
