Abstract
Sugar levels relate to aggression in couples without supporting the glucose model of self-control.
Highlights
Using creative measures of aggressive tendencies, the authors examined the relationship between blood glucose levels and proxies for intimate partner violence
Note that the original multi-study report by Gailliot et al (2007) argued that self-control depletion is mediated by blood glucose levels on the basis of nine studies, all of which produced significant results
Effect sizes were strongly negatively correlated with sample sizes, and the probability of obtaining the observed pattern of only significant results was less than 1%, (Schimmack, 2012), implying that the role of blood glucose in determining self-control capacities is likely to be overstated
Summary
Low glucose relates to greater aggression in married couples by Bushman, B. Using creative measures of aggressive tendencies, the authors examined the relationship between blood glucose levels and proxies for intimate partner violence. Across 3 weeks of testing, daily measures of blood glucose appeared to be related to the number of needles participants stuck in a voodoo doll supposed to represent their partner.
