Have you come across the author, Alfie Kohn?

Alfie Kohn writes and speaks widely on human behaviour, education and parenting. Here are two of his books which I recommend: 

The Myth Of The Spoiled Child

Challenging the Conventional Wisdom About Children and Parenting

Punished by Rewards

The Trouble with Gold Stars, Incentive Plans, A’s, Praise, and Other Bribes
