A new study shows that what you wear can enhance your brain's powers of attention.
Specifically, what you wear can actually affect your performance on cognitive tests.
Among its many findings, people who put on a white coat that they believed belonged to a doctor made fewer errors on tests of attention than those who put on a white coat they believed belonged to an artist.
The researchers, led by Adam D. Galinsky, a business school professor at Northwestern University's Kellogg School of Management, say that what causes the effect is knowing that physicians have to be careful and pay close attention to their work.
The study is a twist on a growing scientific field called embodied cognition, which has already brought us findings such as the fact that if if you wash your hands, you are less likely to make harsh moral judgments for crimes. The field has also shown us that if you meet someone while holding a hot drink in your hand, you will rate him or her as warmer, but if you meet a person while holding a cold drink in your hand, you'll believe him or her to be colder.
Galinsky calls the effect shown in his study "enclothed cognition" to show that different clothes probably affect our cognition in different ways.
The first experiment, which tested selective attention, had 58 undergraduates randomly assigned to wear either a white lab coat or street clothes. They were then tested on how easily they noticed incongruities, such as when the word "red" appeared in green lettering. The lab coat-wearers made half as many errors as those in everyday clothing.
In the second experiment, which tested sustained attention, 74 students wore a doctor's coat, wore a painter's coat, or took the test in a room where they saw a doctor's coat. They then had to look at two very similar pictures side by side and ferret out four minor differences. Again, because their attention was heightened, those in the doctor's coat noticed more differences than those wearing the artist's coat (even though it was the same coat) or those who saw the doctor's coat.
The third experiment tested whether simply seeing the coat could affect behavior. Students either put on a doctor’s coat or a painter’s coat, or were told to look for a long period of time at a doctor’s lab coat on the desk in front of them. Each of the students then wrote essays about the coats. They then took another test on sustained attention.
Again, the group that wore the doctor’s coat got the biggest boost in attention.
The study, which was published in The Journal of Experimental Social Cognition, adds a new twist on what has long been common knowledge: the “clothing affects how other people perceive us as well as how we think about ourselves,” Dr. Galinsky told The New York Times.
Previous experiments have shown that women who go to job interviews dress in a masculine fashion are more likely to be hired, and that a teaching assistant dressed more formally is perceived as more intelligent than one dressed more casually.

It is interesting that doctor uniforms increase brain power since doctors are responsible for more deaths annually than any other reason by far. Doctors seem to think that they know more than everyone else but they make more errors than the weather men. Uniforms in school is probably a good idea, just don't make the uniforms appear to be doctors coats.
It has long been known that wearing a uniform makes people "act" the part. So does this mean that kids should put on uniforms, something that sends the message that they are "students", and should act the part?
I do think there are some charter schools and other experimental schools that have had good success with uniforms. But, I suspect that another reason schools do it is to prevent children from being distracted by baubles or becoming jealous of/fighting with each other. However, now they know there could a good side effect: more attentiveness from the students! Laura
