Intrinsic motivation is the drive that comes from within oneself to engage in an activity or task. Unlike extrinsic motivation, which is driven by external rewards or consequences, intrinsic motivation is more about the enjoyment and satisfaction that comes from the activity itself. Measuring intrinsic motivation is important in various fields such as psychology, education, and sports, as it can provide valuable insights into individual behavior and performance.
