Abstract

The strength model of self-regulation uses a muscle analogy to explain patterns of ego depletion, conservation of willpower, and improved performance after frequent exercise. Our 2007 overview of the literature has been well cited, presumably because of the phenomenon's importance to theories of selfhood and a wide assortment of applied contexts, including problem behaviors. Some researchers have put forward rival theoretical accounts, and others have questioned the existence of the phenomenon. The weight of evidence continues to support the usefulness of the strength model, albeit amid continuing updates and revisions.
