A meta-analysis of 83 studies tested the effect of ego depletion on task performance and related outcomes, alternative explanations and moderators of the effect, and additional strength model hypotheses. Results revealed a significant effect of ego depletion on self-control task performance. Significant effect sizes were found for ego depletion on effort, perceived difficulty, negative affect, subjective fatigue, and blood glucose levels. Small, nonsignificant effects were found for positive affect and self-efficacy. Moderator analyses indicated minimal variation in the effect across sphere of depleting and dependent task, frequently used depleting and dependent tasks, presentation of tasks as single or separate experiments, type of dependent measure and control condition task, and source laboratory. The effect size was moderated by depleting task duration, task presentation by the same or different experimenters, intertask interim period, dependent task complexity, and use of dependent tasks in the choice and volition and cognitive spheres. Motivational incentives, training on self-control tasks, and glucose supplementation promoted better self-control in ego-depleted samples. Expecting further acts of self-control exacerbated the effect. Findings provide preliminary support for the ego-depletion effect and strength model hypotheses. Support for motivation and fatigue as alternative explanations for ego depletion indicate a need to integrate the strength model with other theories. Findings provide impetus for future investigation testing additional hypotheses and mechanisms of the ego-depletion effect. ]]> Fri, 06 Apr 2012 06:51:19 -0500 http://fitmarker.com/misc/ego-depletion-and-the-strength-model-of-self-control/ http://fitmarker.com/misc/redefining-the-kilogram-physicists-zero-in-on-measurement-of-plancks-constant/ Mon, 20 Feb 2012 21:42:44 -0600 http://fitmarker.com/misc/redefining-the-kilogram-physicists-zero-in-on-measurement-of-plancks-constant/ http://fitmarker.com/misc/ama-study-reveals-no-lung-damage-from-casual-marijuana-smoking/ casual marijuana use does not harm lung function. It was just a few months ago in October that the California Medical Association adopted a position urging the legalization of marijuana at its annual meeting. At the time, I reported that the California Medical Association acknowledged in its position that marijuana carries health risks, not unlike the use of nicotine and alcohol, but qualified that it should also be legal and regulated like nicotine and alcohol, arguing that the effects of prohibition have caused more harm to public health and families than the potential risks of marijuana use. ]]> Wed, 18 Jan 2012 08:25:02 -0600 http://fitmarker.com/misc/ama-study-reveals-no-lung-damage-from-casual-marijuana-smoking/ http://fitmarker.com/misc/scientific-process-rage-electron-cafe/ Fri, 05 Aug 2011 15:49:24 -0500 http://fitmarker.com/misc/scientific-process-rage-electron-cafe/ http://fitmarker.com/misc/interactive-games-to-promote-behavior-change-in-prevention-and-treatment/ Mon, 18 Apr 2011 00:55:49 -0500 http://fitmarker.com/misc/interactive-games-to-promote-behavior-change-in-prevention-and-treatment/ http://fitmarker.com/misc/the-pitfalls-of-body-fat-measurement-part-3-bod-pod/ Wed, 09 Mar 2011 14:40:43 -0600 http://fitmarker.com/misc/the-pitfalls-of-body-fat-measurement-part-3-bod-pod/ http://fitmarker.com/misc/be-huge-die-younger-or-be-puny-live-long/ Thu, 23 Dec 2010 23:06:43 -0600 http://fitmarker.com/misc/be-huge-die-younger-or-be-puny-live-long/ http://fitmarker.com/misc/insulin-an-undeserved-bad-reputation-part-4-the-biggest-insulin-myth-of-them-all-weightology-weekly/ Sun, 05 Sep 2010 17:18:23 -0500 http://fitmarker.com/misc/insulin-an-undeserved-bad-reputation-part-4-the-biggest-insulin-myth-of-them-all-weightology-weekly/
