Positive reinforcement is a type of conditioning that involves adding something pleasant or rewarding to increase the likelihood of a behavior being repeated. It works by strengthening desirable behaviors through rewards, such as praise, treats, or other positive stimuli, which make the individual more likely to engage in those actions again in the future. This technique is commonly used in animal training and education, but can also be applied in various aspects of life, including parenting, workplace management, and self-improvement.
