Abstract Lying is cognitively demanding and presumably requires self-regulation. According to ego depletion theory, a task that self-regulation should therefore impair an individual’s ability tell convincing lie in later task. Consequently, it was hypothesized manipulation of would enhance behavioral differences between liars truth-tellers. To manipulate depletion, participants worked (vs. did ...

Performing an act of self-regulation such as making decisions has been suggested to deplete a common limited resource, which impairs all subsequent self-regulatory actions (ego depletion theory). It has however remained unclear whether self-referred decisions truly impair behavioral control even in seemingly unrelated cognitive domains, and which neurophysiological mechanisms are affected by th...

Motivation is underappreciated in self-regulation theories (as is true in social personality psychology at large). This paper reviews the role of motivation in the context of the strength, or limited-resource, model of self-control in several domains. Sacrificing one desire in order to pursue another is more difficult when the incipient response is strongly motivated, a notion that highlights t...

In the present article, we analyzed the role of self-control strength and state anxiety in sports performance. We tested the hypothesis that self-control strength and state anxiety interact in predicting sports performance on the basis of two studies, each using a different sports task (Study 1: performance in a basketball free throw task, N = 64; Study 2: performance in a dart task, N = 79). T...

Relationship Between Autonomous Motivation and Ego-Depletion by Mark A. Heilman MS, Walden University, 2012 Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Social Psychology Walden University May 2016 Abstract Previous research has shown that exerting self-control on a demanding task can impair performance on a subsequent demanding self-c...

The “strength” model conceptualizes selfcontrol as a limited resource (Baumeister et al., 1998). Individuals are able to exert self-control, but only for a limited period after which capacity declines leading to reduced self-control capacity; a state known as ego-depletion. The model has generated a sizable literature confirming the ego-depletion effect in multiple spheres. Our meta-analysis of...
