a b s t r a c tAccording to the limited strength model (Muraven, Tice & Baumeister, 1998), exerting self-control causes ego depletion: a depletion of cognitive resources resulting in poorer performance on later self-control tasks. Previous studies have demonstrated a positive effect of self-awareness on self-control performance. The present study examined whether the occurrence of ego depletion can be circumvented by increasing selfawareness. Initially depleted participants who received a neutral prime exhibited the classic ego depletion pattern: their performance on a subsequent physical self-control task decreased significantly. In contrast, no decrease in performance was observed for depleted participants who were exposed to a self-awareness prime. The latter group performed equally well compared to low depleted participants.Knowing what is best for you does not always lead to behavior that is congruent with this knowledge. Terms such as "weakness of will" and "lack of self-control" have been used by modern philosophers and psychologists to explain this phenomenon (Elster, 1979). Failure of self-control is often accompanied by negative consequences: widespread problems like obesitas, drug addiction and violence reflect people's inability to control their food intake, cravings and aggressive impulses. According to the limited strength model, failure of selfcontrol emerges as a consequence of limited resources (Muraven & Baumeister, 2000;Muraven, Tice, & Baumeister, 1998). Resources used for an initial self-control attempt are no longer available for later attempts, resulting in decreased self-control performance. This phenomenon is labeled ego depletion and has been demonstrated in a wide range of studies. These studies have used different manipulations of self-control (e.g. thought suppression, emotion regulation, impulse control, deliberate decision making and memory tasks) and have indeed shown that when people repeatedly exert self-control within a relatively short period of time, performance on a subsequent act of self-control is likely to decrease (see for an overview, Hagger, Wood, Stiff, & Chatzisarantis, 2010;Schmeichel & Baumeister, 2004).An important question is whether regulatory failure due to ego depletion can be circumvented. The present article will address this question by investigating the potential of attentional processes to overcome ego depletion. More specifically, the present contribution addresses the impact of self-focused attention or self-awareness on regulatory performance and ego depletion.
Self-awarenessPrevious research has consistently demonstrated a unidirectional link between self-focused attention and self-control. For instance, a study by Beaman, Klentz, Diener, and Svanum (1979) showed that children were less likely to eat more than the allowed amount of candy when their self-awareness was raised by seating them in front of a mirror. Macrae, Bodenhausen, and Milne (1998) found that a heightened self-focus enhanced spontaneous suppression of social stereotypes. Highly self-aw...
