A motivation theory refers to an explanation or model that helps us understand why individuals behave in certain ways, what drives their actions, and the factors that influence their level of motivation.
Intrinsic motivation refers to engaging in an activity for its own sake or because it is personally rewarding. For example, studying psychology out of genuine interest and curiosity.
Extrinsic motivation involves engaging in an activity to earn rewards or avoid punishments. An example would be studying psychology to pass an exam and receive a good grade.
This theory emphasizes three basic psychological needs - autonomy, competence, and relatedness - which are essential for intrinsic motivation and personal growth.
