The relationship between exclusion or rejection and aggression is already well documented, but there is still a debate about the mechanisms that underlie this effect. In two studies we focused on the propensity to react aggressively (readiness for aggression) on the bases of emotional, cognitive or self-enhancement (personality-immanent) processes. In both studies we first measured readiness for aggression and then ego-depleted participants. Next, in Study 1 we excluded participants (n = 96) using an online ball throwing game and measured displaced aggressive behavior - intensity and duration of an unpleasant noise administrated to a stranger. In Study 2 participants (n = 140) were rejected by a peer on the basis of an interview that they gave and then could retaliate by reducing peer's chance for getting a job. The results show that exclusion effect on displaced aggression was moderated by cognitive readiness for aggression, while rejection effect on retaliatory aggression was shaped by emotional and personality-immanent readiness for aggression as well as ego-depletion. The results were discussed in light of the strength model of self-control by Baumeister, Vohs, and Tice (2007).

An influential line of research suggests that initial bouts of self-control increase the susceptibility to self-control failure (ego depletion effect). Despite seemingly abundant evidence, some researchers have suggested that evidence for ego depletion was the sole result of publication bias and p-hacking, with the true effect being indistinguishable from zero. Here, we examine (a) whether the evidence brought forward against ego depletion will convince a proponent that ego depletion does not exist and (b) whether arguments that could be brought forward in defense of ego depletion will convince a skeptic that ego depletion does exist. We conclude that despite several hundred published studies, the available evidence is inconclusive. Both additional empirical and theoretical works are needed to make a compelling case for either side of the debate. We discuss necessary steps for future work toward this aim.

During the past two decades, self-control research has been dominated by the strength model of self-control, which is built on the premise that the capacity for self-control is a limited global resource that can become temporarily depleted, resulting in a state called ego depletion. The foundations of ego depletion have recently been questioned. Thus, although self-control is among the most researched psychological concepts with high societal relevance, an inconsistent body of literature limits our understanding of how self-control operates. Here, we propose that the inconsistencies are partly due to a confound that has unknowingly and systematically been introduced into the ego-depletion research: boredom. We propose that boredom might affect results of self-control research by placing an unwanted demand on self-control and signaling that one should explore behavioral alternatives. To account for boredom in self-controlled behavior, we provide a working model that integrates evidence from reward-based models of self-control and recent theorizing on boredom to explain the effects of both self-control exertion and boredom on subsequent self-control performance. We propose that task-induced boredom should be systematically monitored in self-control research to assess the validity of the ego-depletion effect.

Recently, the most prominent model of self-control, the strength model, was criticized, and other explanations of self-control have been proposed. One of them is a concept of lay, implicit, willpower theories, that is, believing either that willpower is limited (as in the strength model) or nonlimited. Research shows that holding a nonlimited-resource belief prevents individuals from suffering ego depletion and is related to successful self-regulation. The current study explored how personality, time perspective, and intelligence predict willpower theories. Additionally, two aspects of willpower theories, strenuous mental activity and resistance to temptations, were measured separately. The results indicated that the two aspects of willpower theories were not correlated with each other. This supports hypothesis that willpower theories may be domain specific and also suggests that these two aspects should not be aggregated into one, homogenous scale as was done in some previous research. Both aspects of holding a nonlimited-resource theory were related positively to emotional stability and negatively to past negative time perspective. Strenuous mental activity was positively associated with intellect and negatively with present fatalism, whereas resistance to temptations was correlated positively with conscientiousness and future time perspective. There were no relations between willpower theories and intelligence, which posits that similar life outcomes related with these two attributes are based on distinct mechanisms. Regression analyses revealed that only personality traits (emotional stability and conscientiousness) remained significant predictors of willpower beliefs.

Ego depletion is embroiled in a crisis that has cast doubts over the legitimacy of the phenomenon itself and its theoretical explanation. I first summarize and analyze the strength model of self- control as cohesive theoretical explanations of the phenomenon and highlight the difficulties it creates for depletion researchers. I conclude that the strength model is not the best theoretical explanation for the depletion phenomenon. Rather, I propose reconceptualizing the ego depletion effect as transient cognitive fatigue (TCF). To support this theoretical shift, I highlight how both the classic and disparate findings in the depletion literature cleanly map into the literature on cognitive fatigue, and how considering depletion to be TCF accommodates existing theoretical alternatives to the strength model.

AbstractThe depletion effect, a decreased capacity for self-control following previous acts of self-control, is thought to result from a lack of necessary psychological/physical resources (i.e., “ego depletion”). Kurzban et al. present an alternative explanation for depletion; but based on statistical techniques that evaluate and adjust for publication bias, we question whether depletion is a real phenomenon in need of explanation.

A prominent, hotly debated idea—the ‘ego depletion’ phenomenon—suggests that engaging in effortful, demanding tasks leads to poorer subsequent self-control performance. Several theories seek to explain the emergence of ego depletion effects. The two most prominent ones are the strength model of self-control (Baumeister & Vohs, 2016) and the process model of self-control (Inzlicht & Schmeichel, 2012). Predictions of these models are predominantly identical on the behavioral level. The models’ predictions differ, however, on the level of invested mental effort. The present pre-registered study (N = 179) contrasted these competing predictions combining an established moderator counteracting ego depletion effects (i.e., self-affirmation) and psychophysiological indicators of mental effort (i.e., systolic blood pressure and pre-ejection period). Our data provide moderate evidence for ego-depletion—decrements in self-control performance after a high- versus low-demanding task in the non-affirmed conditions. Self-affirmation had an unexpected effect: Contrary to previous research, self-affirmed participants performed similarly poorly as participants in the high demand+non-affirmed condition. Although this unexpected finding limited the ability to contrast competing model predictions, it points to hitherto unknown effects of self-affirmation on self-control performance. Systolic blood pressure reactivity emerged as a valid indicator of invested mental effort, but the data show no sign of disengagement after a high demanding task predicted by the process (but not the strength) model. We explore systolic blood pressure progression across the sequential task paradigm, suggest a testable account for the effects of self-affirmation on self-control performance, and discuss theoretical implications of the results for the two competing models.
