Implicit theories about willpower as a moderator of the adverse effect of daily self-control demands on need for recovery

Recent research has demonstrated that peoples’ implicit theories about willpower (whether willpower is seen as a limited vs. nonlimited resource) influence the adverse effects of self-control demands (SCDs) on psychological strain. However, these findings have not yet been transferred to occupational settings where employees are increasingly facing high SCDs in their everyday work. Integrating recent findings on implicit theories about willpower and arguments brought up by the strength model of self-control, we propose that employees who believe that willpower is a limited resource have a stronger need for recovery after a demanding workday than employees who believe that willpower is a nonlimited resource. In a diary study covering ten working days (N = 71), we examine implicit theories about willpower as a moderator of the adverse day-specific effects of SCDs on need for recovery. Our results provide support for our hypothesis. In particular, on days with high levels of SCDs, believing in willpower as a limited resource enhances the need for recovery. We then discuss these findings in light of the strength model of self-control. Practical Relevance: Coping with self-control constitutes a major stressor at work and is related to high psychological strain. Therefore, identifying and understanding boundary conditions that can reduce the adverse consequences from exerting self-control at work is an important step towards creating healthy working environments.

Does Self-Control Training Improve Self-Control? A Meta-Analysis

Self-control is positively associated with a host of beneficial outcomes. Therefore, psychological interventions that reliably improve self-control are of great societal value. A prominent idea suggests that training self-control by repeatedly overriding dominant responses should lead to broad improvements in self-control over time. Here, we conducted a random-effects meta-analysis based on robust variance estimation of the published and unpublished literature on self-control training effects. Results based on 33 studies and 158 effect sizes revealed a small-to-medium effect of g = 0.30, confidence interval (CI95) [0.17, 0.42]. Moderator analyses found that training effects tended to be larger for (a) self-control stamina rather than strength, (b) studies with inactive compared to active control groups, (c) males than females, and (d) when proponents of the strength model of self-control were (co)authors of a study. Bias-correction techniques suggested the presence of small-study effects and/or publication bias and arrived at smaller effect size estimates (range: gcorrected = .13 to .24). The mechanisms underlying the effect are poorly understood. There is not enough evidence to conclude that the repeated control of dominant responses is the critical element driving training effects.

Too Exhausted to Perform at the Highest Level? On the Importance of Self-control Strength in Educational Settings.

In order to perform at the highest level in educational settings (e.g., students in testing situations), individuals often have to control their impulses or desires (e.g., to study for an upcoming test or to prepare a course instead of spending time with the peer group). Previous research suggests that the ability to exert self-control is an important predictor of performance and behavior in educational contexts. According to the strength model, all self-control acts are based on one global energy pool whose capacity is assumed to be limited. After having performed a first act of self-control, this resource can become temporarily depleted which negatively affects subsequent self-control. In such a state of ego depletion, individuals tend to display impaired concentration and academic performance, fail to meet academic deadlines, or even disengage from their duties. In this mini-review, we report recent studies on ego depletion which have focused on children as well as adults in educational settings, derive practical implications for how to improve self-control strength in the realm of education and instruction, and discuss limitations regarding the assumptions of the strength model of self-control.

When shoppers don’t have enough self-control resources: applying the strength model of self-control

PurposeThis study aims to empirically test and explain shoppers’ purchase behavior in a retail store by applying the strength model of self-control.Design/methodology/approachA pretest was used to identify shoppers’ purchase change behavior based on 500 average shoppers, followed by a main study based on another set of 166 average shoppers, to test the proposed hypotheses.FindingsAs shoppers stay shorter in a grocery store, they tend to change their purchase decisions more frequently. In addition, this study results reveal that three behavioral variables, namely, shoppers’ changed purchase decisions, shopping duration and walking distance, significantly predict their overall spending.Research limitations/implicationsThe findings from the current study are limited to a designated superstore conducted for this study only. From a managerial viewpoint, the author suggests that giving shoppers more choice options and encouraging them to spend more time and walk further in a grocery store, depleting their self-control resources, can be an effective strategy in increasing sales. Yet, excessive efforts for these ideas can also cause shoppers’ massive returns once they return to the normal state with sufficient self-control resources.Originality/valueThe current study empirically confirms the applicability of the strength model of self-control through field studies designed to increase the external validity of the findings. To the best of the author’s knowledge, this research is the first to apply and empirically test the strength model of self-control in the field to explain shopper behavior and highlight the importance of understanding shoppers’ changed purchase decisions.

Self-control depletion and nicotine deprivation as precipitants of smoking cessation failure: A human laboratory model.

The need to understand potential precipitants of smoking relapse is exemplified by relapse rates as high as 95%. The Self-Control Strength model, which proposes that self-control is dependent upon limited resources and susceptible to fatigue, may offer insight into relapse processes. The current study tested the hypothesis that self-control depletion (SCD), produced from engagement in emotional suppression, would serve as a novel antecedent for cessation failure, as indexed by a validated laboratory analogue of smoking lapse and relapse. We also examined whether SCD effects interacted with those of a well-established relapse precipitant (i.e., nicotine deprivation). Craving and behavioral economic indices (delay discounting and demand) were tested as hypothesized mechanisms for increased cessation failure. Ultimately, a moderated mediation model was used to test nicotine deprivation as a hypothesized moderator of SCD effects. We used a 2 × 2 (12-hr deprivation vs. no deprivation; SCD vs. no SCD) factorial between-subjects design (N = 128 smokers). The primary hypothesis of the study was supported, as SCD increased lapse behavior (p = .04). Nicotine deprivation significantly increased craving, cigarette demand, delay discounting, and lapse behavior. No main effects were found for SCD on putative mediators (i.e., craving, demand, and discounting), but the SCD and deprivation manipulations interacted upon craving (p = .04). The moderated mediation model was significant. SCD was found to increase craving among nicotine deprived smokers, which mediated effects on lapse behavior. SCD appears to play an important role in smoking relapse and may be a viable target for intervention. (PsycINFO Database Record

High-disinhibition restrained eaters are disinhibited by self-regulatory depletion in the food-related inhibitory control

Restrained eating for weight control and loss is becoming highly prevalent in many affluent societies, while most of the restrained eaters are rather unsuccessful in the long term. According to the strength model of self-control, the disinhibition effect of restrained eaters may occur after the depletion of self-control resources. However, no work has examined the direct impact of self-control resources on inhibitory control ability of restrained eaters. This study investigated the influences of self-control resources on the food-related inhibitory control among high-restraint/low-disinhibition restrained eaters, high-restraint/high-disinhibition restrained eaters and unrestrained eaters using stop signal task. Results reveal that there’s no difference of food-related inhibitory control between three groups when the self-control resources are non-depleted, while high-restraint/high-disinhibition restrained eaters showing a decrease of food-related inhibitory control after ego-depletion. This disinhibition effect only seems to occur in samples of restrained eaters with a high tendency toward overeating.

An experimental analysis of acquired impulse control among adult humans intolerant to alcohol

The ability to control tempting impulses impacts health, education, and general socioeconomic outcomes among people at all ages. Consequently, whether and how impulse control develops in adult populations is a topic of enduring interest. Although past research has shed important light on this question using controlled intervention studies, here we take advantage of a natural experiment in China, where males but not females encounter substantial social pressure to consume alcohol. One-third of our sample, all of whom are Han Chinese, is intolerant to alcohol, whereas the remaining control sample is observationally identical but alcohol tolerant. Consistent with previous literature, we find that intolerant males are significantly more likely to exercise willpower to limit their alcohol consumption than alcohol-tolerant males. In view of the strength model of self-control, we hypothesize that this enables improved impulse control in other contexts as well. To investigate this hypothesis, we compare decisions in laboratory games of self-control between the tolerant and intolerant groups. We find that males intolerant to alcohol and who regularly encounter drinking environments control their selfish impulses significantly better than their tolerant counterparts. On the other hand, we find that female Han Chinese intolerant to alcohol do not use self-control to limit alcohol consumption more than tolerant females, nor do the tolerant and intolerant females exhibit differences in self-control behaviors. Our research indicates that impulse control can be developed in adult populations as a result of self-control behaviors in natural environments, and shows that this skill has generalizable benefits across behavioral domains.

Self-control strength and physical exercise: An ecological momentary assessment study

ObjectiveWe tested predictions made by the self-control strength model on a day level using ecological momentary assessment methodology. The study examined the relationship between self-control strength and physical exercise in participants who intended to exercise on a regular basis. We hypothesized that individuals would exercise more on days when their self-control strength was high than on days when their self-control strength was low and that trait self-control would moderate this relationship. MethodsN = 63 students aged between 19 and 32 years participated in the study. Self-control strength and physical exercise were assessed daily over a period of 20 days with an electronic diary. ResultsMultilevel analyses revealed that the level of self-control strength was positively associated with physical exercise (p = 0.01), and this relationship was stronger in individuals with low trait self-control than in those with high trait self-control (interaction effect: p = 0.03). ConclusionThese findings highlight the interplay between momentarily fluctuating variables such as self-control strength and dispositional variables such as trait self-control in the prediction of physical exercise.

Shaping aggressive personality in adolescence: Exploring cross-lagged relations between aggressive thoughts, aggressive behaviour and self-control

Aggressive ideations can be defined as thoughts, daydreams or fantasies of harming another. They feature in theoretical models of aggressive behaviour causation and are used in violence risk assessments. Little is known, however, about long term relations between aggressive ideations, aggressive behaviour and related variables such as self-control. We examined cross-lagged associations between these variables in the most recent two waves of the Zurich project on social development (z-proso) when the participants were aged 15 and 17. We found that aggressive ideations were highly stable across this time span. The only significant cross-lagged effects were between aggressive behaviour at age 15 and self-control and aggressive ideations at age 17. Results are consistent with the strength model of self-control in which changes in specific self-controlled behaviour can produce generalised changes in self-control. They are also consistent with the hypothesis that aggressive ideations are more a reaction to or a reflection of shared causes with, rather than a cause of, aggressive behaviour. Future studies should aim to integrate measurements across short and long time scales in order to further understand the causal interactions between aggressive ideations and behaviours as they play out across at the state and trait level.

The Strength Model of Self-Control in Sport and Exercise Psychology.

The strength model of self-control assumes that all acts of self-control (e.g., emotion regulation, persistence) are empowered by a single global metaphorical strength that has limited capacity. This strength can become temporarily depleted after a primary self-control act, which, in turn, can impair performance in subsequent acts of self-control. Recently, the assumptions of the strength model of self-control also have been adopted and tested in the field of sport and exercise psychology. The present review paper aims to give an overview of recent developments in self-control research based on the strength model of self-control. Furthermore, recent research on interventions on how to improve and revitalize self-control strength will be presented. Finally, the strength model of self-control has been criticized lately, as well as expanded in scope, so the present paper will also discuss alternative explanations of why previous acts of self-control can lead to impaired performance in sport and exercise.

Ego‐depletion and aggressive behavior

Multiple theoretical frameworks postulate that ego-depletion can influence aggressive behavior. Our experimental study assessed whether ego-depletion is related to aggressive behavioral change and whether provocation moderated this effect. Aggression was measured by asking participants to take raffle tickets from an ostensible partner. First, participants were randomly assigned to either high or low ego-depletion (by having them memorize a short or long number throughout the entire study) prior to engaging in the first ticket exchange. Participants were then either provoked (or not) by having their "partner" take more or fewer tickets than the partner originally requested. The ticket exchange occurred three times to assess behavioral change. Results showed that aggression was highest for ego depleted participants who were provoked. Implications are discussed in terms of the General Aggression Model and the Strength Model of Self-Control. Aggr. Behav. 42:533-541, 2016. © 2016 Wiley Periodicals, Inc.

Emotional, Cognitive and Self-Enhancement Processes in Aggressive Behavior After Interpersonal Rejection and Exclusion.

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).

The Influence of Chronic Ego Depletion on Goal Adherence: An Experience Sampling Study.

Although ego depletion effects have been widely observed in experiments in which participants perform consecutive self-control tasks, the process of ego depletion remains poorly understood. Using the strength model of self-control, we hypothesized that chronic ego depletion adversely affects goal adherence and that mental effort and motivation are involved in the process of ego depletion. In this study, 203 students reported their daily performance, mental effort, and motivation with respect to goal directed behavior across a 3-week time period. People with high levels of chronic ego depletion were less successful in goal adherence than those with less chronic ego depletion. Although daily effort devoted to goal adherence increased with chronic ego depletion, motivation to adhere to goals was not affected. Participants with high levels of chronic ego depletion showed a stronger positive association between mental effort and performance, but chronic ego depletion did not play a regulatory role in the effect of motivation on performance. Chronic ego depletion increased the likelihood of behavior regulation failure, suggesting that it is difficult for people in an ego-depletion state to adhere to goals. We integrate our results with the findings of previous studies and discuss possible theoretical implications.

Neuroenhancement and the strength model of self-control.

Neuroenhancement (NE), the use of substances as a means to enhance performance, has garnered considerable scientific attention of late. While ethical and epidemiological publications on the topic accumulate, there is a lack of theory-driven psychological research that aims at understanding psychological drivers of NE. In this perspective article we argue that self-control strength offers a promising theory-based approach to further understand and investigate NE behavior. Using the strength model of self-control, we derive two theory-driven perspectives on NE-self-control research. First, we propose that individual differences in state/trait self-control strength differentially affect NE behavior based on one’s individual experience of NE use. Building upon this, we outline promising research questions that (will) further elucidate our understanding of NE based on the strength model’s propositions. Second, we discuss evidence indicating that popular NE substances (like Methylphenidate) may counteract imminent losses of self-control strength. We outline how further research on NE’s effects on the ego-depletion effect may further broaden our understanding of the strength model of self-control.

Ego depletion and the use of mental contrasting

Mentally contrasting a desired future with present reality leads to goal pursuit in accordance with people’s expectations of realizing the desired future. Because mental contrasting is a purposeful self-regulation strategy that involves mental effort and complex information processing we suspected that people who are depleted or mentally fatigued are less likely to mentally contrast than those who are not. Indeed, participants who performed a depleting first task were less likely to subsequently mentally contrast about an important personal wish than those who performed a nondepleting first task. However, activating the desired future and present reality by priming (Study 1) or increasing the demand for mental contrasting by confronting participants with an impending task (Study 2) counteracted the effect of depletion on the reduced use of mental contrasting. We discuss implications for the use of mental contrasting and the strength model of self-control.

Out of Control

Family violence is common and brings tremendous costs to individuals, relationships, and society. Victims are vulnerable to negative outcomes across a host of dimensions, including cognitive performance, impulse control, emotion regulation, and physical health. Links between family violence and various problems have been established, yet the specific processes underlying these associations are poorly understood, resulting in the stunted development of effective interventions. This article addresses two key questions: How and why does family violence cause these myriad problems? The self-control strength model of family violence provides novel answers. The model integrates components of existing theories, extending them by pinpointing self-control strength as an explanatory and predictive factor, and can serve as a framework for interventions.

Integrating attentional control theory and the strength model of self-control.

In the present article, we argue that it may be fruitful to incorporate the ideas of the strength model of self-control into the core assumptions of the well-established attentional control theory (ACT). In ACT, it is assumed that anxiety automatically leads to attention disruption and increased distractibility, which may impair subsequent cognitive or perceptual-motor performance, but only if individuals do not have the ability to counteract this attention disruption. However, ACT does not clarify which process determines whether one can volitionally regulate attention despite experiencing high levels of anxiety. In terms of the strength model of self-control, attention regulation can be viewed as a self-control act depending on the momentary availability of self-control strength. We review literature that has revealed that self-control strength moderates the anxiety–performance relationship, discuss how to integrate these two theoretical models, and offer practical recommendations of how to counteract negative anxiety effects.

Episodes of incivility between subordinates and supervisors: examining the role of self-control and time with an interaction-record diary study

Scholars have hypothesized that experiencing incivility not only negatively affects well-being, but may even trigger further antisocial behavior. Previous research, however, has focused mainly on the relation between incivility and well-being. Thus, little is known about the behavioral consequences of incivility. With this in mind, we conducted an interaction-record diary study to examine whether supervisor incivility causes retaliatory incivility against the supervisor. Using the self-control strength model as a framework, we further examined whether the target's trait (trait self-control) and state (exhaustion) self-regulatory capacities moderate this effect. In addition, we examined the role of time by testing the duration of the effect. When we analyzed the full data set, we found no support for our hypotheses. However, using a subset of the data in which the subsequent interaction happened on the same day as the prior interaction, our results showed that experiencing incivility predicted incivility in the subsequent interaction, but only when the time lag between the two interactions was short. Furthermore, in line with the assumption that self-regulatory capacities are required to restrain a target from retaliatory responses, the effect was stronger when individuals were exhausted. In contrast to our assumption, trait self-control had no effect on instigated incivility. Copyright © 2015 John Wiley & Sons, Ltd.

Ego depletion and attention regulation under pressure: is a temporary loss of self-control strength indeed related to impaired attention regulation?

In the current study we investigated whether ego depletion negatively affects attention regulation under pressure in sports by assessing participants' dart throwing performance and accompanying gaze behavior. According to the strength model of self-control, the most important aspect of self-control is attention regulation. Because higher levels of state anxiety are associated with impaired attention regulation, we chose a mixed design with ego depletion (yes vs. no) as between-subjects and anxiety level (high vs. low) as within-subjects factor. Participants performed a perceptual-motor task requiring selective attention, namely, dart throwing. In line with our expectations, depleted participants in the high-anxiety condition performed worse and displayed a shorter final fixation on bull's eye, demonstrating that when one's self-control strength is depleted, attention regulation under pressure cannot be maintained. This is the first study that directly supports the general assumption that ego depletion is a major factor in influencing attention regulation under pressure.

A theory-based behavior-change intervention to reduce alcohol consumption in undergraduate students: trial protocol.

BackgroundExcessive alcohol consumption on single occasions among undergraduate students is a major health issue as research has shown this pattern of drinking to be related to maladaptive health and psychosocial outcomes. Brief, theory-based interventions targeting motivation and self-control as behavior-change techniques have been identified as effective means to reduce alcohol consumption, but few studies have examined the interactive effects of these components. The aim of the present study is to develop a brief theory-based intervention using motivational and self-control intervention techniques to reduce alcohol consumption in undergraduate students.Methods/DesignThe intervention will adopt a factorial design to test the main and interactive effects of the techniques on alcohol consumption. Using mental simulations and the strength model of self-control as the theoretical bases of the intervention, the study will adopt a fully randomized 2 (mental simulation: mental simulation vs. control irrelevant visualization exercise) × 2 (self-control training: challenging Stroop task vs. easy Stroop task) between-participants design. Non-abstinent undergraduate students aged 18 years or older will be eligible to participate in the study. Participants will complete an initial survey including self-reported alcohol consumption measures, measures of motivation and self- measures. Participants will be randomly allocated to receive either a mental simulation exercise presented in print format or a control irrelevant visualization exercise. Thereafter, participants will be randomly assigned to receive a challenging online self-control training exercise or an easy training exercise that has little self-control demand over the course of the next four weeks. Four weeks later participants will complete a follow-up alcohol consumption, motivation and self-control measures.DiscussionThis study will provide the first evidence for the individual and interactive effects of motivational and self-control training techniques in an intervention to reduce alcohol consumption. It will also demonstrate the importance of adopting multiple theoretical perspectives and a factorial design to identify the unique and interactive impact of behavior-change techniques on health behavior.Trial registrationThe trial is registered with the Australian and New Zealand Clinical Trials Registry, ACTRN12613000573752.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-1648-y) contains supplementary material, which is available to authorized users.
