What does positive reinforcement do?

Positive reinforcement is a behavioral principle in which a behavior is strengthened or increased by introducing a desirable stimulus following that behavior. When an individual exhibits a desired behavior and is met with a positive consequence—such as praise, treats, or rewards—it reinforces the likelihood that the behavior will be repeated in the future. This principle is widely used in training animals, including pets, to encourage them to perform specific desirable behaviors.

By applying positive reinforcement effectively, trainers can shape behaviors over time, making it a foundational aspect of behavior modification strategies. The key element here is the introduction of a positive stimulus that strengthens the bond between the behavior and its positive outcome, thus fostering learning and encouraging repeat actions.
