Hell's Kitchen Motivation

So I was watching Hell's Kitchen the other day and it was my first time watching it. I was literally appalled and felt soo bad for the contestants. The head chef, Chef Ramsey yells the worst, most hurtful things I have ever heard someone say to someone. The horrible thing is that he yells at them so harshly for some of the smallest mistakes. Watching this show and seeing how Chef Ramsey motivates his contestants I started thinking about if this type of negative motivation works. I agree that harsh, punishment-filled motivation is a successful way to motivate, but why is it that positive motivation doesn't have the same effect. How sad is that? We need someone screaming profanity in our face to get us to do something properly, but by asking nicely we might just blow it off. Personally, I think I work best with people who are harsh on me, but at the same time offer positive support. I need someone who will push me to my limits, but will know when to back off at the same time right before I may break down. Lets just say I won't be on Hell's Kitchen anytime soon!
