If you are a leader, Make sure you give props.

How do you guys feel about praise in design school? I have always pushed hard to get critique as soon as possible on every new concept for a project I produced on my course and that is often from lecturers who know good design and (being from a good school here in England) have high standards. All my friends have NEVER asked for critique because to be honest, they are often terrified. Do you think praise from lecturers should be so scarce in Design school as if in industry? Do you think it gets to the point where it simply deters students from asking for critique if they receive little praise for the good stuff and only criticism for the bad?
