Motivation is an important concept in psychology and education.
Intrinsic motivation means doing an activity for the pure joy, interest, or satisfaction that it brings.
For example, a student may read books because they love learning, not because they want a reward or prize.
In contrast, extrinsic motivation is driven by external rewards like money, grades, or praise from others.
Options like Increment motivation and Incentive-based motivation are not standard psychological terms for this concept.
Teachers and managers often try to increase intrinsic motivation to build genuine interest and self-driven efforts.
Thus, when the motivation comes from within, it is called intrinsic motivation.
