 Intrinsic rewards are unconditioned rewards that are attractive and motivate behavior because they are inherently pleasurable.Extrinsic rewards (e.g., money or seeing one's favorite sports team winning a game) are conditioned rewards that are attractive and motivate behavior, but are not inherently pleasurable.Extrinsic rewards derive their motivational value as a result of a learned association (i.e., conditioning) with intrinsic rewards.
