Role of Glucose in Resistance to Persuasion

Abstract

The present study sought to provide evidence that susceptibility to persuasion is dependent on glucose. Depleted participants given a sugar substitute did show agreement with the counterattitudinal essay as predicted, but the difference was not significant. Furthermore, depleted participants given glucose did disagree with the policy as predicted; however, control participants in this group showed surprising agreement with the policy as well. This agreement in the control group is surprising given that previous research has shown the opposite effect; therefore this effect should be further investigated (Burkley, 2008). However, the findings that was in the predicted directions give promise for future research. Although statistical significance was not met in the conducted analyses, predicted directions of the overall interaction and main effects lend support to the hypothesis that glucose increases an individual's resistance to persuasion.
