You walk into a room and spy a plate of gooey doughnuts dripping with chocolate frosting. But wait: You were saving your sweets allotment for a party later today. If it feels like one part of your brain is battling another, it probably is, according to a newly published study.
Researchers at the University of Pittsburgh, Carnegie Mellon University, Harvard University and Princeton University found two areas of the brain that appear to compete for control over behavior when a person attempts to balance near-term rewards with long-term goals. The research involved imaging people’s brains as they made choices between small but immediate rewards or larger rewards that they would receive later. The study grew out of the emerging discipline of neuroeconomics, which investigates the mental and neural processes that drive economic decision-making.
