When a child does something bad - lies, doesn’t want to wash, doesn’t study well - parents react immediately. But what is done right often goes unnoticed. One of the most authoritative psychologists in the world, head of the Center for Parenting at Yale, Alan Kazdin, believes that praise can be extremely effective. However, in order for it to influence behavior change, it must be applied in a specific way. It is useless to simply say “Great! Great!” a hundred times a day. Well done!" This book talks about how to praise correctly.
