University of Pennsylvania Analysis: Contrary to Popular Models, Sugar Is Not Burned by Self-Control Tasks
PHILADELPHIA –- Contradicting a popular model of self-control, a University of Pennsylvania psychologist says the data from a 2007 study argues against the idea that glucose is the resource used to manage self control and that humans rely on this energy source for will power.
The analysis, conducted by Robert Kurzban and published in the current issue of the journal Evolutionary Psychology, shows that evidence previously presented in favor of the claim that the brain consumes extra glucose when people exert self-control shows no such thing.
