If you're a parent, you can play this strategy on your children, instead of a simple star reward chart, where good task = reward, reward spuriously and without cue, when you reward them, tell them you know they are always trying hard to do the right thing and are proud of how often they make a good choice, maybe point out something they could have done better if it's recent enough to be recalled... With a star chart children are adept at learning the minimum requirements for reward, and the point of the reward, for good behaviour, is lost in the game...
