Yesyes to the dangers of providing extrinsic motivators in the hope of developing intrinsic motivation. But I bet I'm not the only one who does it despite the evidence; we offer entitlement to minutes of time playing computer games for various things we want DS to do, notably music practice. There's a class of things which I am so convinced are worthwhile for him to do that I am going to coerce him into doing them if necessary; he does have intrinsic motivation, but it only stretches far enough for him to want to have done them, rather than far enough for him to actually do them in preference to reading right now... So sue me :-/
