Reinforcer

A reinforcer is a stimulus or event that increases the likelihood of a specific behavior occurring again. It operates through the principles of reinforcement, a core concept in behavioral psychology. Reinforcers can be positive (adding something desirable) or negative (removing something undesirable) to strengthen a response. The effectiveness of a reinforcer depends on individual preferences, timing, and consistency. They play a crucial role in learning and shaping behavior across various contexts, from animal training to human education and workplace management. Properly applied, reinforcers can motivate desired actions, facilitate skill acquisition, and influence habit formation.
