Intrinsic motivation comes from one's desire to achieve or attain a goal. Pursuing challenges and goals come easier and more enjoyable when one is intrinsically motivated to complete a certain objective because the individual is more interested in learning, rather than achieving the goal. Edward Deci and Richard Ryan's theory of intrinsic motivation is essentially examining the conditions that “elicit and sustain” this phenomenon. Deci and Ryan coined the term “cognitive evaluation theory" which concentrates on the needs of competence and autonomy. The CET essentially states that social-contextual events like feedback and reinforcement can cause feelings of competence and therefore increase intrinsic motivation. However, feelings of competence will not increase intrinsic motivation if there is no sense of autonomy. In situations where choices, feelings, and opportunities are present, intrinsic motivation is increased because people feel a greater sense of autonomy. Offering people choices, responding to their feelings, and opportunities for self-direction have been reported to enhance intrinsic motivation via increased autonomy (Deci & Ryan, 1985).
