A team of Japanese researchers at the National Institute for Physiological Sciences has discovered that the more a person is complimented the more the striatum part of their brain is stimulated, and the better they perform a task.
“Compliments are as good as cash at making us work harder,” ran the ensuing headline.
I praise my 6 year old, who is a very, very bright little guy, when he does something well, remind him to always do his best even when it is easy to complete a project at half speed and to learn from his mistakes when he screws up and that everyone makes mistakes. Giving praise for nothing is counterproductive with him because he would see right through it and then wouldn't appreciate it when it is deserved. I think that works for most kids but YMMV.
You asked for Obamamerica, now you are going to get it. Stand by for suck.
