reinforcer
Noun: 1. (Psychology): A stimulus (any event or object) that is presented or occurs after a behavior, and which increases the likelihood of that behavior being repeated in the future. It strengthens the association between the behavior and its consequence. 2. (General): Something that strengthens, supports, or makes an effect more powerful.
The term is most precisely used in the context of behavioral psychology (operant conditioning). It describes the consequence that follows a behavior to make it more frequent. * In a positive context, a reinforcer is a rewarding stimulus added (e.g., a treat for sitting). * In a negative context, a reinforcer is an aversive stimulus that is removed or avoided (e.g., stopping a loud noise when a button is pressed).
