Extrinisic Motivation holds the premise that individuals will engage in sometimes distasteful tasks to receive tangible rewards such as money, time off, or good grades.The rewards must be greater than the cost to the individual.
Intrinsic Outcome Motivation leads a person to a task because he or she believes a behavior will bring about intrinsic satisfaction. The activity or task still represents a cost that must be overcome by the intrinsic satifaction of internal validation or external validation from others. Examples might include service professions or public office.
Intrinsic Process Motivation includes activites that are internally driven and are engaged in regardless of extrinsic factors. Actions based on intrinsic process motivation have the sole expectation of continued enjoyment or pleasure.
