Investigators at Northwestern University set up a series of experiments in which subjects performed cognitive tasks that measured selective or sustained attention. In one trial some subjects wore white coats and some didn’t; interestingly, those who did performed better by a factor of 2, according to a blog on KevinMD.com.
In another experiment, all the subjects wore white coats but some were told they were wearing a doctor’s coat, while others were told they were wearing a painter’s coat. The doctor’s coat group scored significantly better. The results led the investigators to coin the term enclothed cognition, which they defined as the systematic influence that clothes have on the wearer’s psychological processes, wrote Michael Edmond, a professor of internal medicine and chair, division of infectious diseases, VCU Medical Center.
"While I’ll have to bow to science and come to grips with the concept of enclothed cognition, I still believe that keeping patients from contact with contaminated coat sleeves trumps whatever small intellectual edge the white coat might provide. As the psychologists have shown, it’s all in your head," Edmond wrote.
