Ego-depletion: Replicability and mechanisms
The ego-depletion effect has been celebrated and much maligned in equal measure.
In this presentation, I will outline the chequered history of the ego-depletion effect and ‘strength’ model of self-control from its inception and rise as a dominant effect and theory in psychology, to concerns over its replicability and the explanatory value and validity of strength model claims.
I will outline the basic ideas behind the effect and its origins, typical means to test and measure it, competing explanations, and controversies and questions over its existence. In particular, I will draw from cumulative evidence from numerous meta-analyses of the effect and a recent multi-lab replication. I will also outline how responses to the replication has served to catalyze new research and replications efforts toward moving the field forward.
I will also outline some research conducting on ego-depletion in the field of health behaviour, particularly dieting, alcohol consumption, smoking, and physical activity. I will argue that some of the consistent effects for ego-depletion exist in applied contexts, particularly for appetitive, rewarding behaviours. I will use this as a basis to suggests future directions for research in this domain.
