Fighting self-control failure: Overcoming ego depletion by increasing self-awareness

According 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 self-awareness. 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.     

I want to keep on exercising but I don’t: The negative impact of momentary lacks of self-control on exercise adherence

ObjectivesWe investigated the impact of state and trait self-control strength on exercise execution. We hypothesized that state self-control strength is reduced on days that are perceived as stressful and that reductions in self-control strength result in a lower likelihood to work out. Additionally, trait self-control strength may affect the execution of workout plans.DesignUniversity students, who stated that they have not been exercising regularly for at least one month, filled in a trait self-control inventory, a personality questionnaire, and were instructed to perform a daily workout over a one-week period. Perceived stress levels, state self-control strength, and workout completion were assessed on a daily basis.ResultsResults revealed that people were less likely to exercise on days they perceived as stressful. State self-control mediated the relation between stress and exercise completion. Trait self-control and other personality variables did not affect workout completion.ConclusionsResults indicate that daily stress is associated with self-control depletion and a lower likelihood to work out.     

Ego depletion by response exaggeration

Suppressing or inhibiting responses has a host of negative effects, including a temporary reduction in self-regulatory strength (ego depletion). Less attention has been given to response exaggeration, which should also deplete regulatory strength and therefore disrupt subsequent self-control. We tested the depletion hypothesis by having participants perform tests of cognitive fluency after exaggerating responses (or not) to a disgusting film clip. Response exaggeration produced increased emotional expression but did not increase subjective emotional experience. Moreover, exaggerating disgust reactions impaired subsequent performance on tests of cognitive fluency. The cognitive aftereffects of exaggeration were not attributable to emotional experience or to changes in sympathetic or parasympathetic arousal (as indicated by skin conductance and heart rate variability high frequency power, respectively). Poorer cognitive fluency after response exaggeration indicates a detrimental effect of purposeful self-regulation.     

Ego depletion,attentional control,and decision making in sport

ObjectivesAthletes differ at staying focused on performance and avoiding distraction. Drawing on the strength model of self-control we investigated whether athletes do not only differ inter-individually in their disposition of staying focused and avoiding distraction but also intra-individually in their situational availability of focused attention.Design/methodIn the present experiment we hypothesized that basketball players (N = 40) who have sufficient self-control resources will perform relatively better on a computer based decision making task under distraction conditions compared to a group who's self-control resources have been depleted in a prior task requiring self-control.ResultsThe results are in line with the strength model of self-control by demonstrating that an athlete's capability to focus attention relies on the situational availability of self-control strength.ConclusionsThe current results indicate that having sufficient self-control strength in interference rich sport settings is likely to be beneficial for decision making.     

Adapting to an initial self-regulatory task cancels the ego depletion effect

The resource-based model of self-regulation provides a pessimistic view of self-regulation that people are destined to lose their self-control after having engaged in any act of self-regulation because these acts deplete the limited resource that people need for successful self-regulation. The cognitive control theory, however, offers an alternative explanation and suggests that the depletion effect reflects switch costs between different cognitive control processes recruited to deal with demanding tasks. This account implies that the depletion effect will not occur once people have had the opportunity to adapt to the self-regulatory task initially engaged in. Consistent with this idea, the present study showed that engaging in a demanding task led to performance deficits on a subsequent self-regulatory task (i.e. the depletion effect) only when the initial demanding task was relatively short but not when it was long enough for participants to adapt. Our results were unrelated to self-efficacy, mood, and motivation.     

Is ego depletion associated with increased distractibility? Results from a basketball free throw task

ObjectivesIt has been repeatedly demonstrated that athletes in a state of ego depletion do not perform up to their capabilities in high pressure situations. We assume that momentarily available self-control strength determines whether individuals in high pressure situations can resist distracting stimuli.Design/methodIn the present study, we applied a between-subjects design, as 31 experienced basketball players were randomly assigned to a depletion group or a non-depletion group. Participants performed 30 free throws while listening to statements representing worrisome thoughts (as frequently experienced in high pressure situations) over stereo headphones. Participants were instructed to block out these distracting audio messages and focus on the free throws. We postulated that depleted participants would be more likely to be distracted. They were also assumed to perform worse in the free throw task.ResultsThe results supported our assumption as depleted participants paid more attention to the distracting stimuli. In addition, they displayed worse performance in the free throw task.ConclusionsThese results indicate that sufficient levels of self-control strength can serve as a buffer against distracting stimuli under pressure.     

Investigating the effects of ego depletion on physical exercise routines of athletes

Objectives

Persisting at a task can temporarily reduce one’s ability to persist at subsequent tasks. This phenomenon is known as “ego depletion”. Although ego depletion has been linked to many cognitive tasks less is known about its effect on physical tasks. Even less is known about its effect on practiced physical performance associated with athletes. In modern sport science, the question as to whether or not ego depletion can reduce athletes’ persistence at practiced behaviour should be particularly important. Two experimental studies investigated if ego depletion can reduce athletes’ persistence at a routine physical exercise.

Design

In both experiments, a repeated measures design was employed.

Method

Competitive rowers (Experiment 1) and competitive hockey and rugby players (Experiment 2) attempted to complete as many press-ups (Experiment 1) or sit-ups (Experiment 2) as possible over two separate phases. In one phase, the participants attempted the physical exercise after completing an easy cognitive task. In the other phase, they attempted the physical exercise after completing a difficult cognitive task.

Results

Experiment 1 demonstrated that the competitive rowers completed fewer press-ups after completing a difficult cognitive task than they did after completing an easy task. Experiment 2 demonstrated that the competitive hockey and rugby players completed fewer sit-ups after completing a difficult cognitive task than they did after completing an easy cognitive task.

Conclusions

These findings indicate that athletes’ exercise routines are susceptible to ego depletion and that the strength model of self-regulation is applicable to athletic performance.     

And deplete us not into temptation: Automatic attitudes, dietary restraint, and self-regulatory resources as determinants of eating behavior

Linking contemporary models of self-regulation to recent research on automatic attitudes, the present study investigated the impact of automatic candy attitudes, dietary restraint standards, and self-regulation resources on eating behavior. Participants were assigned to either an emotion suppression task (low self-regulation resources) or an emotion flow task (high self-regulation resources), and were then given an opportunity to taste candies. When self-regulation resources were high, candy consumption was uniquely related to dietary restraint standards (but not automatic candy attitudes). In contrast, when self-regulation resources were low, candy consumption was primarily predicted by automatic candy attitudes, with dietary restraint standards showing a tendency for counterintentional effects. These results indicate that the behavioral impact of automatic attitudes and personal standards depends on available control resources. Implications for research on automatic attitudes and self-regulation are discussed.     

Bringing out the agreeableness in everyone: Using a cognitive self-regulation model to reduce aggression

Research has shown that those individuals high in agreeableness recruit helpful thoughts in hostile contexts, presumably in the service of controlling aggressive behavior. The present experiment follows from such work, but importantly does so in a manner seeking to support causal conclusions. Participants were randomly assigned to an experimental training condition, in which hostile prime words were followed by helpful target words, or to a control condition that did not involve such pairings. Those assigned to the experimental condition subsequently exhibited lower levels of aggression in a laboratory task. Additional considerations and findings support the potential involvement of self-regulation processes. In general terms, the experiment reveals that a brief cognitive manipulation targeting processes thought to underlie aggression control was in fact causally effective in reducing subsequent levels of aggressive behavior.     

Differentiating the effects of self-control and self-esteem on reactions to mortality salience

Whereas many previous studies suggest that self-esteem may buffer against the psychological threat of death, recent research has begun to suggest that self-control also may serve as a buffer. Two studies examined the possibility that dispositional self-control uniquely predicts responses to mortality salience, above and beyond self-esteem. In Study 1, an initial exercise in emotion regulation increased subsequent accessibility of death thoughts. In Study 2, mortality salience increased worldview defense. Both of these effects were moderated by dispositional self-control, such that the effects occurred among participants with low but not high self-control. More importantly, these moderating effects were observed over and above the moderating effects of self-esteem. Findings suggest that self-control may serve as an important and unique buffer against thoughts of death.     

Resource depletion does not influence prospective memory in college students

This paper reports an experiment designed to investigate the potential influence of prior acts of self-control on subsequent prospective memory performance. College undergraduates (n = 146) performed either a cognitively depleting initial task (e.g., mostly incongruent Stroop task) or a less resource-consuming version of that task (e.g., all congruent Stroop task). Subsequently, participants completed a prospective memory task that required attentionally demanding monitoring processes. The results demonstrated that prior acts of self-control do not impair the ability to execute a future intention in college-aged adults. We conceptually replicated these results in three additional depletion and prospective memory experiments. This research extends a growing number of studies demonstrating the boundary conditions of the resource depletion effect in cognitive tasks.     

Ego depletion and its paradoxical effects on ethical decision making

Whereas previous research has shown that ego depletion can lead to an increase in unethical behavior, we suggest that this effect hinges on the social consensus of the unethical behavior. Drawing from theories on social consensus and dual-process decision-making, we hypothesize and confirm that ego depletion is associated with increased unethical behavior of comparatively low social consensus. We then find that, as hypothesized, ego depletion is associated with decreased unethical behavior of high social consensus (Studies 1 and 2). Results further suggest that, controlling for state self-control resources, depleted participants are less likely to engage in unethical behavior of high social consensus as a result of increased subjective fatigue (Study 3). Taken together, our findings challenge a widely-held assumption about the negative effects of ego depletion on ethical decision making.     

Verbal intelligence and self-regulatory competencies: Joint predictors of boys’ aggression

Two studies examined the interactive effect of receptive verbal intelligence measured by the Peabody Picture Vocabulary Test and self-regulatory competencies measured in the delay of gratification paradigm on boys’ aggression. Study 1 participants (N = 98) were middle school, low-income boys primarily ethnic minority. Participants for Study 2 (N = 59) were drawn from a treatment camp for boys from low-income neighborhoods with behavioral adjustment problems. In both studies, the interaction between verbal intelligence and self-regulation was significant such that verbal intelligence was associated with lower aggression to a greater extent among boys who had effective self-regulatory skills than among those who had ineffective self-regulatory skills. The implications of these findings for interventions and for a theory of risk factors in aggression are discussed.     

Unable to resist temptation: How self-control depletion promotes unethical behavior

Across four experimental studies, individuals who were depleted of their self-regulatory resources by an initial act of self-control were more likely to “impulsively cheat” than individuals whose self-regulatory resources were intact. Our results demonstrate that individuals depleted of self-control resources were more likely to behave dishonestly (Study 1). Depletion reduced people’s moral awareness when they faced the opportunity to cheat, which, in turn, was responsible for heightened cheating (Study 2). Individuals high in moral identity, however, did not show elevated levels of cheating when they were depleted (Study 3), supporting our hypothesis that self-control depletion increases cheating when it robs people of the executive resources necessary to identify an act as immoral or unethical. Our results also show that resisting unethical behavior both requires and depletes self-control resources (Study 4). Taken together, our findings help to explain how otherwise ethical individuals predictably engage in unethical behavior.     

Restoring the self: Positive affect helps improve self-regulation following ego depletion

Previous work has shown that acts of self-regulation appear to deplete a psychological resource, resulting in poorer self-regulation subsequently. Four experiments using assorted manipulations and measures found that positive mood or emotion can counteract ego depletion. After an initial act of self-regulation, participants who watched a comedy video or received a surprise gift self-regulated on various tasks as well as non-depleted participants and significantly better than participants who experienced a sad mood induction, a neutral mood stimulus, or a brief rest period.     

Regulatory job stressors and their within-person relationships with ego depletion: The roles of state anxiety,self-control effort,and job autonomy

Our research aimed at disentangling the underlying processes of the adverse relationship between regulatory job stressors and ego depletion. Specifically, we analyzed whether state anxiety and self-control effort would mediate the within-person relationships of time pressure, planning and decision-making, and emotional dissonance with ego depletion. In addition, we also tested potential attenuating effects of situational job autonomy on the adverse effects of regulatory job stressors on state anxiety, self-control effort, and ego depletion. Based on an experience sampling design, we gathered a sample of 97 eldercare workers who provided data on 721 experience-sampling occasions. Multilevel moderated serial mediation analyses revealed that time pressure and emotional dissonance, but not planning and decision-making, exerted significant serial indirect effects on ego depletion via state anxiety and self-control effort. Finally, we found conditional serial indirect effects of all three regulatory job stressors on ego depletion as a function of job autonomy. Theoretical implications for scholarly understanding of coping with regulatory job stressors are discussed.     

Hormones and aggression in childhood and adolescence

This review is a survey on recent psychobiosocial studies on association between hormones and aggression/violence in children and adolescents, with a special focus on puberty, given the rapid changes in both hormones and behavior occurring during that developmental period. Since it cannot be assumed that all readers have much background knowledge, it inevitably begins with some comments about the concept and multifaceted nature of aggression, as well as with a brief reminding about hormone candidates to be linked to aggression during human development. Then, we finish off with the status of its knowledge in today's science, tackling in a systematic way with the main data published, hormone by hormone. The origin of the gender-based differences in aggression must lie in neuroendocrinological events occurring during prenatal life or early in postnatal life. A complex and indirect effect of testosterone on aggression is proposed. A low HPA axis activity seems associated with chronic aggressive and antisocial behaviors. It is also suggested that early adrenal androgens contribute to the onset and maintenance of persistent violent and antisocial behavior, and that it begins early in life and persists into adulthood, at least in young boys. There are also some studies suggesting an association between aggression and some pituitary hormones in children, even if present data are still far from being consistent. The hormone-aggression link during development thus is not consistently reported. There can be an indirect relation in three ways: hormones can be involved in the development of aggression as a cause, as a consequence, or even as a mediator. Psychosocial factors may influence the causation and progression of violence in children through hormonal action.     

The frontal lobe and aggression

Frontal lesions often lead to psychosocial problems. It is not surprising that frontal lobe dysfunctions have been proposed to underlie antisocial behaviour in individuals without apparent lesions. However, physical aggression and violence have never been systematically related to acquired lesions. Whereas, traditional neuropsychological testing identifies problems in cognitive and emotional information processing, recent brain-imaging studies have revealed both the frontal structural and functional underpinnings of antisocial behaviour. Careful characterization of antisocial behaviour subtypes seems to indicate that cognitive-neuropsychological function is systematically poor in physical aggression and hyperactivity. Recent refinements point to biological and genetic moderators of that association.
