• Question: My question is related to reward. I find myself hesitating to give rewards at times as I don’t want to give too many and devalue them. Is there any evidence that this is can be the case?

      Hi. Yes this is certainly a feature of rewards, that they become less rewarding if given too often. One way around this might be to make the reward uncertain, in the sense that there is an element of luck or randomness about getting a reward. There seem to be stronger brain responses to uncertain rewards than predictable ones, and there are projects going on now to try to harness this for educational purposes. e.g. see http://www.bristol.ac.uk/education/people/academicStaff/edpahj/publications/mbe_1108.pdf
