Definition
Noun: A positive stimulus is a stimulus that has desirable or beneficial consequences. It is something in the environment that elicits a favorable response, encourages a behavior, or is generally perceived as rewarding or pleasant.
Usage
This term is primarily used in psychology, behavioral science, and learning theory. It describes any event, object, or situation that is presented following a behavior to increase the likelihood of that behavior being repeated. It is a core concept in operant conditioning.
