Intrinsic and Extrinsic Motivation A motivation may be intrinsic, extrinsic, or both. Intrinsic motivation is the motivation to act for the sake of the activity alone. For example, people have intrinsic motivation to write poetry if they do it simply because they enjoy it. Extrinsic motivation, on the other hand, is the motivation to act for external rewards. For example, people have extrinsic motivation to write if they do so in the hopes of getting published, being famous, or making money. Incentives An incentive is an environmental stimulus that pulls people to act in a particular way.
