The researchers used brain scans to try and study the biology of dread. They tried to study as to how much attention the brain pays to the expected pain determines and whether someone is an extreme dreader, they are trying to suggesting that simple diversions could alleviate the misery.
The research, published in the journal Science, is part of a new field called neuroeconomics that uses brain imaging to try to understand how people make choices. Until now, most of that work had been focused on reward that things people will do for positive outcomes.
Dr. Gregory Berns of Emory University, who led the new study, told The Associated Press, that they were interested in the dark side of the equation, as he explained that dread often makes us make bad decisions. The standard economic theory says people should postpone bad outcomes for as long as possible, because something might happen in the interim to improve the outlook.
