I'm not sure you understand the concept of affirmation. If a child stole a candy bar, criticizing the child in such a manner can actually be positively reinforcing because it gives the child attention. A considerably better response would probably be to take the candy bar away from the child and return it without giving the child any attention whatsoever. Not speaking to or acknowledging the child, and effectively cutting off attention to that child for a duration, instills a far stronger message than criticizing the child would. Children crave attention, and to deny it serves as a punishment that is not really a punishment, but rather a neutral action by the parent which has stronger implications for the child than an actual punishment would have.
Um...sure.

You are entitled to your opinion. I've seen no evidence to actually indicate that this is the truth, and nothing I've learned from developmental psychology supports this opinion.
