The more I consider motivation, the more I realise it is one of those things we in gamification use as a catch-all. It’s a bit like how we treat the term “game mechanics” and, well, gamification!
Generally speaking, you will hear the terms intrinsic and extrinsic when motivation is spoken about. You will hear Deci & Ryan, Dan Pink, Maslow and more spoken about. However, when it comes down to it our argument is always the same. Intrinsic motivation is always better than extrinsic rewards. At times you will also hear a further comment that a balance of extrinsic rewards and intrinsic motivation will yield the best results.
