“A new Dartmouth study reveals that interracial contact has a profound impact on a person’s attention and performance. The researchers found new evidence using brain imaging that white individuals attempt to control racial bias when exposed to black individuals, and that this act of suppressing bias exhausts mental resources.

Published in the online edition of Nature Neuroscience on Nov. 16, the study combines the use of functional magnetic resonance imaging (fMRI), which measures brain activity, with other behavioral tests common to research in social and cognitive psychology to determine how white individuals respond to black individuals.” —EurekAlert!
