Gratification is the pleasurable emotional reaction of happiness in response to a fulfillment of a desire or goal. It is also identified as a response stemming from the fulfillment of social needs such as affiliation, socializing, social approval, and mutual recognition.

Gratification, like all emotions, is a motivator of behavior and plays a role in the entire range of human social systems.
