Nov 9, 2016. Professor Edward R. Hirt’s presentation on Counteracting Depletion: Adventures in resource replenishing was an especially appropriate colloquium topic for the day following a late night of presidential election coverage! Professor Hirt, from the Department of Psychological and Brain Sciences at Indiana University, presented his research on the potentially restorative effects of expectations and beliefs on mental fatigue. Across an impressive number of high caliber experiments, Professor Hirt and his colleagues demonstrated that expectations about the potential influence of variables, such as positive mood, on mental energy are central factors in ego-depletion and restoration. He finds that both manipulated and idiosyncratic expectancies moderate mood’s conventional influences on self-control. Theoretically, his work suggests that expectations of mental energy change are central in self-control and ego-depletion.
