Reinforcement is a key principle in behavior modification and learning theory, primarily defined by its effect on behavior. It refers to any stimulus or event that increases the likelihood of a behavior being repeated. In other words, when reinforcement occurs, it strengthens the behavior, leading to an increase in that behavior over time.

In contrast, punishment involves introducing a consequence that reduces or decreases the likelihood of a behavior being repeated. It may take the form of an aversive stimulus (positive punishment) or the removal of a desirable stimulus (negative punishment), but the ultimate goal is to decrease a specific behavior.

This distinction is fundamental in understanding behavior modification strategies. Reinforcement and punishment are often used in different contexts with different objectives. While reinforcement aims to encourage desirable behavior, punishment seeks to discourage undesirable behavior. Since reinforcement is primarily focused on increasing behavior and punishment is aimed at decreasing behavior, this differentiates the two concepts clearly.
