The ego-depletion effect: Results and implications of a multi-lab pre-registered replication

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 model 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 future replication efforts.
