Positive reinforcement is a concept in behavioral psychology that involves adding a rewarding stimulus following a desired behavior, which increases the likelihood of that behavior being repeated. For example, when a child receives praise or a treat for completing their homework, they are more likely to do it again in the future. This technique is widely used in various settings, including education and animal training. By consistently applying positive reinforcement, individuals can encourage good behavior and foster a positive learning environment. It emphasizes the importance of rewards in shaping behavior and promoting motivation.
