Giving in to Temptation”: Self-Control as a Valuable But Limited Resource?

Life constantly challenges us with temptations that we have to resist to follow the rules of society and achieve our goals. The strength model of self-control (SC) posits that SC capacity relies on limited mental energy that can be depleted. In the present review article, we analyze and explore past and current research on the SC construct. Departing from different approaches to the conceptualization and operationalization of the SC construct, we review and synthetize the major fi ndings on the strength model of SC and on the ego depletion effect. We also review past and new fi ndings on both the benefi ts, mainly for life outcomes, and the costs of SC failures. Next, we present and discuss some recent alternative and complementary approaches to current SC perspectives. Finally, we conclude by presenting some theoretical and empirical considerations and implications in an attempt to encourage future research and applied intervention in the broad fi eld of SC.
