A depleted mind feels inefficacious: Ego‐depletion reduces self‐efficacy to exert further self‐control

Recent research has found that ego‐depletion undermines self‐control by motivating cognition that justifies conservation of mental resource. One potential cognitive mechanism is reduction of self‐efficacy. Specifically, we propose that ego‐depletion might demotivate self‐control by making people believe that they are inefficacious in exerting self‐control in subsequent tasks. Three experiments support the proposal. First, we demonstrated that (a) ego‐depletion can reduce self‐efficacy to exert further control (Experiments 1 to 3) and (b) the temporary reduction of self‐efficacy mediates the effect of depletion on self‐control performance (Experiment 2). Finally, we found that (c) these effects are only observed among participants who endorse a limited (versus non‐limited) theory of willpower and are, hence, more motivated to conserve mental resources (Experiment 3). Taken together, the present findings show that decrease in self‐efficacy to exert further self‐control is an important cognitive process that explains how ego‐depletion demotivates self‐control. This research also contributes to the recent discussion of the psychological processes underlying ego‐depletion.     

Let There Be Variance: Individual Differences in Consecutive Self‐control in a Laboratory Setting and Daily Life

The large body of research used to support ego‐depletion effects is currently faced with conceptual and replication issues, leading to doubt over the extent or even existence of the ego‐depletion effect. By using within‐person designs in a laboratory (Study 1; 187 participants) and an ambulatory assessment study (Study 2; 125 participants), we sought to clarify this ambiguity by investigating whether prominent situational variables (such as motivation and affect) or personality traits can help elucidate when ego depletion can be observed and when not. Although only marginal ego‐depletion effects were found in both studies, these effects varied considerably between individuals, indicating that some individuals experience self‐control decrements after initial self‐control exertion and others not. However, neither motivation nor affect nor personality traits such as trait self‐control could consistently explain this variability when models were applied that controlled for variance due to targets and the depletion manipulation (Study 1) or days (Study 2) as well as for multiple testing. We discuss how the operationalization and reliability of our key measures may explain these null effects and demonstrate that alternative metrics may be required to study the consequences of the consecutive exertion of self‐control. © 2019 European Association of Personality Psychology     

Unwilling but not unable to control: Ego depletion increases effortful dishonesty with material rewards

Previous studies have found that ego depletion increases dishonesty. However, it remains unclear whether ego depletion makes participants unable to exert self‐control or unwilling to exert self‐control when it increases dishonesty. The present study aimed to clarify this. Based on the process model, ego depletion causes individuals to pay more attention to material rewards and increases the motivation to act on impulse. Therefore, it is possible that ego‐depleted participants are unwilling, rather than unable, to be honest. We conducted two experiments to examine this hypothesis. Results showed that ego depletion increased material‐based dishonesty even when the dishonest behavior was more complicated and effortful than was the honest behavior. However, participants were reluctant to cheat just for convenience, and ego depletion had no apparent effect on convenience‐based dishonesty without any material rewards. The theoretical implications and future directions of these results are discussed.     

Self‐control depletion impairs goal maintenance: A meta‐analysis

Initial exertion of self‐control has been suggested to impair subsequent self‐regulatory performance. The specific cognitive processes that underlie this ego depletion effect have rarely been examined. Drawing on the dual‐process theory of executive control (Engle & Kane, 2004 ; Kane & Engle, 2003 ), the current meta‐analysis revealed that initial self‐control exertion impairs participants’ capacities of maintaining the task goal but its effect on capacities of resolving response competition is in need of further investigation. Our results are more consistent with recent theoretical views that consider ego depletion as a switch cost and a result arising from reduced motivation to engage in further self‐control.     

The effect of motivation and positive affect on ego depletion: Replenishment versus release mechanism

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing‐out‐letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group. After the experimental treatment, a dumbbell task was used to measure participants' remaining self‐regulatory resources. The results showed that participants in the motivation and positive affect groups performed better on the dumbbell task than participants in the depletion control group. Experiment 2 was similar to Experiment 1 except that participants were asked to perform an additional unexpected dumbbell task after a neutral video following the above procedure. The results of Experiment 1 were replicated; however, participants' performance on the additional dumbbell task differed. The positive affect group performed better than the depletion control group, indicating an increase in self‐regulatory resources and thus supporting the replenishment effect of positive affect. No significant difference was found between the motivation group and the depletion control group.     

Too exhausted to remember: Ego depletion undermines subsequent event‐based prospective memory

Past research has consistently found that people are likely to do worse on high‐level cognitive tasks after exerting self‐control on previous actions. However, little has been unraveled about to what extent ego depletion affects subsequent prospective memory. Drawing upon the self‐control strength model and the relationship between self‐control resources and executive control, this study proposes that the initial actions of self‐control may undermine subsequent event‐based prospective memory (EBPM). Ego depletion was manipulated through watching a video requiring visual attention (Experiment 1) or completing an incongruent Stroop task (Experiment 2). Participants were then tested on EBPM embedded in an ongoing task. As predicted, the results showed that after ruling out possible intervening variables (e.g. mood, focal and nonfocal cues, and characteristics of ongoing task and ego depletion task), participants in the high‐depletion condition performed significantly worse on EBPM than those in the low‐depletion condition. The results suggested that the effect of ego depletion on EBPM was mainly due to an impaired prospective component rather than to a retrospective component.     

Exploring the Interplay of Trait Self‐Control and Ego Depletion: Empirical Evidence for Ironic Effects

Trait self‐control (TSC) has been conceptualized as a general and abstract ability to exert self‐regulation across multiple domains that has mostly beneficial effects. However, its relationship to situational depletion of self‐regulatory resources has received little attention. We systematically explore the interplay of trait and situational self‐control in two studies (total N = 264). In contrast with a positive view of TSC, the results show greater ego depletion effects for high (vs. low) self‐control abilities across such diverse domains as candy consumption (Study 1), risk‐taking behaviour (Study 2) and achievement motivation (Study 2). It is proposed that these ironic effects are attributable to high‐TSC individuals' less frequent active inhibition of impulses in everyday life and their resulting lack of experience in resisting acute temptations. A third study (N> = 358) corroborated this general reasoning by showing that TSC is indeed associated with less frequent impulse inhibition in daily routines. Our data point to a downside of dispositional self‐control in ego depletion paradigms. Other explanations and potential future avenues for resolving inconsistent findings across the literature are discussed. Copyright © 2013 European Association of Personality Psychology     

Self‐Control Success Revealed: Greater Approach Motivation Towards Healthy versus Unhealthy Food

Deviating from existing literature on self‐control failure the current research examines self‐control success and the role of motivation. Functional research suggests people visually perceive objects to be bigger when they are motivated to approach them. Using the size perception task, participants estimated the size of a healthy and an unhealthy food object that were identical in size. In the current research we simulated a reflective state vs. impulsive state using an ego‐depletion manipulation in Study 1 and a cognitive load manipulation in Study 2. Results from both studies revealed that participants in a reflective state (vs. impulsive state) assigned increased size estimations to the healthy food item compared to the unhealthy food item. Current findings demonstrate greater approach motivation towards a ‘virtue’ (i.e., healthy food) as a mechanism that underlies self‐control success, suggesting that successful self‐control involves initiating approach towards a virtue rather than inhibiting a vice.

Overcoming ego depletion: the influence of exemplar priming on self‐control performance

Self‐regulation research suggested that active self‐control depends on a limited resource. Therefore the capacity for self‐control is lower among people who already exercised control, a phenomenon labelled as ego depletion. This experiment examines whether priming of a persistent person exemplar may help to overcome ego depletion. Half of the participants engaged in a demanding self‐control task (solving extremely difficult labyrinths) whereas the other half took part in a task that demanded little self‐control (solving easy labyrinths). Then, half of the participants received a person exemplar prime related to persistence; the other half received a neutral prime. Finally, participants' persistence on a subsequent self‐control task (squeezing a handgrip) was measured. The effect of a person exemplar prime on a subsequent self‐control task depended on initial self‐control demands. Participants who exercised high initial self‐control and were then presented with a persistent exemplar prime showed assimilation. Their handgrip persistence was higher than the persistence of participants who received a neutral prime. Under conditions of low initial self‐control the opposite pattern was found. A persistent person prime resulted in contrast and resulted in lower handgrip performance as compared to those who received a neutral prime. Copyright © 2006 John Wiley & Sons, Ltd.     

Too tired to taint the truth: Ego‐depletion reduces other‐benefiting dishonesty

Numerous studies indicate that ego‐depletion increases the occurrence of self‐benefiting dishonest behavior by undermining resistance to short‐term temptations associated with dishonesty. Turning this phenomenon around, we examined whether ego‐depletion can, counterintuitively, reduce dishonest behavior in a context where dishonesty serves to benefit others. Specifically, based on the notion that ego‐depletion reduces commitment to long‐term/abstract goals and interferes with self‐control, we proposed and found in an experiment that ego‐depleted people are less likely to display dishonest behavior that spares another person from an unpleasant truth. These findings have implications for the study of dishonesty and moral dilemmas in interpersonal settings. Copyright © 2014 John Wiley & Sons, Ltd.     

Depletion from Self‐Regulation: A Resource‐based Account of the Effect of Value Incongruence

Value incongruence between employees and organizations has been identified as a negative work condition. An attitude‐based account suggests that value incongruence gives rise to negative attitudes toward organizations and thus causes low performance. To complement this mechanism, we propose a resource‐based account based on ego‐depletion theory, which suggests that value incongruence consumes an individual's regulatory resources and leads to low work performance. In support of this view, results from 2 survey studies and a vignette experiment reveal that value incongruence is positively associated with ego depletion, which in turn is negatively related to work performance. The mediation effect of ego depletion is independent of the attitude‐based mechanism as represented by job satisfaction and affective commitment. Consistent with the affective consistency perspective, the relationship between value incongruence and ego depletion is stronger among employees high in positive affectivity and weaker among employees high in negative affectivity. The corresponding moderated mediation analysis shows that the indirect effects of value incongruence on work performance through ego depletion vary as a function of positive and negative affectivity. This investigation unravels the self‐regulatory consequence of value incongruence and shows that the resource‐based mechanism of value incongruence operates differentially as a function of dispositional affectivity.     

Action orientation overcomes the ego depletion effect

It has been consistently demonstrated that initial exertion of self‐control had negative influence on people's performance on subsequent self‐control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state‐oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self‐control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task.     

The modality effect of ego depletion: Auditory task modality reduces ego depletion

An initial act of self‐control that impairs subsequent acts of self‐control is called ego depletion. The ego depletion phenomenon has been observed consistently. The modality effect refers to the effect of the presentation modality on the processing of stimuli. The modality effect was also robustly found in a large body of research. However, no study to date has examined the modality effects of ego depletion. This issue was addressed in the current study. In Experiment 1, after all participants completed a handgrip task, one group's participants completed a visual attention regulation task and the other group's participants completed an auditory attention regulation task, and then all participants again completed a handgrip task. The ego depletion phenomenon was observed in both the visual and the auditory attention regulation task. Moreover, participants who completed the visual task performed worse on the handgrip task than participants who completed the auditory task, which indicated that there was high ego depletion in the visual task condition. In Experiment 2, participants completed an initial task that either did or did not deplete self‐control resources, and then they completed a second visual or auditory attention control task. The results indicated that depleted participants performed better on the auditory attention control task than the visual attention control task. These findings suggest that altering task modality may reduce ego depletion.     

Prejudice as Self‐Control Failure1

Research has suggested that whereas stereotypical attitudes may be automatically activated, the response to these stereotypes can be controlled. Anything that interferes with self‐control may result in more biased behavior. The ego strength model hypothesizes that after exerting self‐control, subsequent self‐control performance will suffer. Hence, depletion of ego strength may lead to increased prejudice. In 2 studies, depletion was found only to affect individuals who normally try to control their prejudicial responses. Participants who do not normally try to control their use of stereotypes were equally prejudiced, regardless of their level of ego strength. The results have implications for prejudice and stereotyping, as well as models of self‐control.     

Dispositional optimism,optimism priming,and prevention of ego depletion

Exerting self‐control leads to a diminished capacity to carry out successive acts of self‐control, a process termed ego depletion. The present study investigated whether dispositional optimism, priming of an optimistic orientation, or their interaction can counteract the ego depletion effect. A total of 160 participants performed a self‐control‐demanding weight‐lifting task on two occasions. Half of the participants were depleted between the two weight‐lifting tasks. Because depletion of self‐regulatory resources can undermine optimism half of the participants in the depletion, and no‐depletion condition were primed for an optimistic orientation before performing the second self‐control task. Results demonstrated an interaction between dispositional optimism and optimism priming. Only in participants high in dispositional optimism did the optimism prime lead to undiminished persistence on the weight‐lifting task. These results demonstrate that dispositional optimism may lead to improved goal persistence in the face of adversity only under conditions in which optimistic schemas are activated.

自我控制的能量模型:证据、质疑和展望

自我控制的能量模型是解释自我控制的一个重要理论模型。该模型认为,所有的自我控制行为依赖一种共同且有限的能量,执行自我控制会消耗这种能量,导致自我损耗效应的产生,但能量也可以通过一些方法得以恢复和提升。该模型得到大量行为和生理层面研究的支持,但也有研究者从疲劳、情绪、动机、血糖指标、时间知觉等方面提出质疑。未来研究可从自我能量的性质、总量等角度进一步完善能量模型,同时结合我国文化探讨理想、信念、价值观对提升我国国民意志力的作用。     

Does counting to ten increase or decrease aggression? The role of state self‐control (ego‐depletion) and consequences

In this investigation, we experimentally test the interaction of ego‐depletion (low state self‐control), consequences, and decision‐making time on aggressive responses to an insult from a confederate. The results indicate that ego‐depleted participants respond more quickly and aggressively to an insult from a confederate. However, when a 30‐ second decision‐making delay is imposed, ego‐depleted participants reduce their aggression, but only if there are external consequences to being aggressive. In the absence of such consequences, ego‐depleted participants become more aggressive following a delay. Additionally, if a distracting cognitive load disrupts the 30‐ second delay, aggression levels do not change significantly, even if there are consequences. These results suggest people respond to aggressive triggers more impulsively when ego‐depleted.     

Lay theories of willpower

Some people believe that willpower relies on a limited resource and that performing cognitive work (such as using self‐control) results in mental fatigue. Others believe that willpower is nonlimited and that performing cognitive work instead prepares and energizes them for more. These differing lay theories of willpower determine whether or not one's self‐control performance actually does decrease or increase after use, with only limited willpower theorists showing a decrease (the ego depletion effect). Due to the self‐control requirements of everyday life, willpower theories also predict outcomes across domains of academics, health, goal progress, interpersonal relationships, and well‐being. Generally, limited willpower theorists' belief in their limited capacity results in poorer outcomes, particularly during times of high demand. By understanding how willpower theories form and function, interventions that encourage nonlimited willpower theories may be created to improve people's performance and well‐being.     

The Strength Model of Self-Control

ABSTRACT— Self-control is a central function of the self and an important key to success in life. The exertion of self-control appears to depend on a limited resource. Just as a muscle gets tired from exertion, acts of self-control cause short-term impairments (ego depletion) in subsequent self-control, even on unrelated tasks. Research has supported the strength model in the domains of eating, drinking, spending, sexuality, intelligent thought, making choices, and interpersonal behavior. Motivational or framing factors can temporarily block the deleterious effects of being in a state of ego depletion. Blood glucose is an important component of the energy.
