Clothes and Self-Perception

If you wear a white coat that you believe belongs to a doctor, your ability to pay attention increases sharply. But if you wear the same white coat believing it belongs to a painter, you will show no such improvement.

So scientists report after studying a phenomenon they call enclothed cognition: the effects of clothing on cognitive processes.

It is not enough to see a doctor’s coat hanging in your doorway, said Adam D. Galinsky, a professor at the Kellogg School of Management at Northwestern University, who led the study. The effect occurs only if you actually wear the coat and know its symbolic meaning — that physicians tend to be careful, rigorous and good at paying attention.
