What is intermittent reward schedule?

An intermittent reward schedule involves not consistently delivering rewards at fixed times but rather varying when and how rewards are given. This variability keeps the process of obtaining rewards engaging and motivating because it creates a sense of unpredictability and excitement, much like gambling. When actions are always rewarded, motivation can falter, but if rewards are unexpected, it can enhance motivation and focus.

To maintain motivation across different activities, like exercise or learning, it's beneficial to sometimes reward efforts and other times withhold rewards, thus managing the dopamine levels associated with pleasure and motivation. This approach can help keep activities interesting and maintain engagement over longer periods, even if the activity becomes routine.

An example would be in gaming or exercise, where not every achievement or session is rewarded, or the rewards vary in type and size, making the outcome unpredictable and keeping the activity compelling 1 2.
