Which type of reinforcement involves adding a pleasant stimulus to increase behavior?

Positive reinforcement is a key concept in behavior analysis that involves the addition of a pleasant or rewarding stimulus following a desired behavior, with the intention of increasing the likelihood of that behavior occurring again in the future. For example, if a child receives praise or a treat for completing their homework on time, this reward positively reinforces the behavior of doing homework punctually.

By adding a positive stimulus—such as praise or a tangible reward—the individual experiences a favorable outcome, which enhances the motivation to repeat the behavior. This principle is widely used in various settings, including education, parenting, and animal training, to encourage desirable behaviors effectively.
