Earlier quoted context omitted.
Yeah, says everyone except every reputable psychologist ever, and any parent who hasn't raised an out of control little monster of a child. Negative reinforcement works better than any other form of reinforcement, except when paired with positive reinforcement for desired behaviors, just like innumerable studies and common goddamned sense tell you.
A quick google informs me that punishment != negative reinforcement.
positive reinforcement: presenting nice stimulus to increase frequency of behavior
negative reinforcement: removing unpleasant stimulus to increase frequency of behavior
positive punishment: presenting unpleasant stimulus to decrease frequency of behavior
negative punishment: removing nice stimulus to decrease frequency of behavior
The great confusion stems from the fact that in common English language, with punishment we mean both increasing good behavior and reducing bad behavior, whilst in classical conditioning terms, punishment always refers to reducing the frequency of a certain behavior.
