Mechanisms of self-control failure: motivation and limited resources

Research has found that individuals who are lower in self-control strength because of previous self-control exertions perform more poorly on subsequent tests of self-control. The present studies suggest that this effect may be moderated by motivation. In particular, depletion and motivation jointly determine self-control performance. Individuals who were depleted and believed that the task would help others (Experiment 1) or believed that their efforts could benefit them (Experiment 2) performed better on a subsequent test of self-control than individuals who were depleted and lower in motivation. The results of Experiment 3 replicated these findings and suggested that depletion only affects performance on tasks that require self-control; tasks that are difficult but do not require self-control are immune to the effects of depletion. Hence, depleted individuals may compensate for their lack of self-control resources when sufficiently motivated. The results may help explain the nature of self-control strength.     

Positive affect and self-control: Attention to self-control demands mediates the influence of positive affect on consecutive self-control

Positive affect (PA) can either improve or impair self-control performance, depending on whether two tasks are dissimilar, and thus require flexible releasing and switching, or similar, which requires stable maintenance. The present study suggests that this effect is mediated by attentional shifts. The authors found that participants under PA, who performed on two dissimilar tasks and had to switch to a new response dimension, were less attentive to distracting information compared to neutral affect (NE), leading to better performance. In contrast, participants under PA who did not have to switch, were more attentive to distracting information compared to participants under NE. These findings highlight the opposite effects of PA on consecutive self-control.     

Trait self-control predicts performance on behavioral tests of self-control

Two studies tested the extent to which trait self-control predicts performance on objective laboratory tests of behavioral self-control. In Study 1, participants attempted to refrain from blinking for a period of 2 minutes. Participants who reported higher trait self-control blinked less often than participants who reported lower trait self-control. In Study 2, participants attempted to tolerate a painful stimulus, and those higher in trait self-control tolerated pain longer than participants lower in trait self-control. These findings indicate that self-reported self-control corresponds moderately well with performance on objective behavioral tests of self-control. The discussion focuses on implications for self-control theory.     

Rude and inappropriate: the role of self-control in following social norms

Following social norms to avoid deviant or socially inappropriate behavior may require self-control. This was tested in two experiments that experimentally manipulated individuals' level of self-control strength. In the first experiment, individuals whose self-control capacity was depleted were more likely to misrepresent how many problems they solved and work after being told to stop while working on a timed test. These same results were found in individuals low in trait self-control. This was especially true when the certainty of getting caught was low. In the second experiment, depleted individuals were ruder to the experimenter than nondepleted participants. The results have implications for understanding how self-control contributes to normative behavior.     

Conserving self-control strength

Individuals may be motivated to limit their use of self-control resources, especially when they have depleted some of that resource. Expecting to need self-control strength in the future should heighten the motivation to conserve strength. In 4 experiments, it was found that depleted participants who anticipated exerting self-control in the future performed more poorly in an intervening test of self-control than participants who were not depleted, and more poorly than those who did not expect to exert self-control in the future. Conversely, those who conserved strength performed better on tasks that they conserved the strength for as compared with those who did not conserve. The underlying economic or conservation of resource model sheds some light on the operation of self-control strength.     

Mindfulness meditation counteracts self-control depletion

Mindfulness meditation describes a set of different mental techniques to train attention and awareness. Trait mindfulness and extended mindfulness interventions can benefit self-control. The present study investigated the short-term consequences of mindfulness meditation under conditions of limited self-control resources. Specifically, we hypothesized that a brief period of mindfulness meditation would counteract the deleterious effect that the exertion of self-control has on subsequent self-control performance. Participants who had been depleted of self-control resources by an emotion suppression task showed decrements in self-control performance as compared to participants who had not suppressed emotions. However, participants who had meditated after emotion suppression performed equally well on the subsequent self-control task as participants who had not exerted self-control previously. This finding suggests that a brief period of mindfulness meditation may serve as a quick and efficient strategy to foster self-control under conditions of low resources.     

Self-Regulated Learning of a Motor Skill Through Emulation and Self-Control Levels in a Physical Education Setting

This study examined the effectiveness of the second and third level of Zimmerman's (2000) model of self-regulated learning development. Participants were 72 (28 boys and 44 girls) fifth- and sixth-grade students who practiced the novel task of dart-throwing. Results showed that sixth-grade Greek students who proceeded sequentially from the emulation to the self-control level improved their dart-throwing performance more than students who missed one or both of these levels, but fifth-grade students benefited equally either from the sequential practice at the emulation and the self-control level or from the experience at one of these self-regulatory levels. No differences were found in self-efficacy, although sixth-grade students who practiced at the emulation level reported higher satisfaction, and sixth-grade students who practiced at the self-control level reported higher intrinsic motivation compared to control group students. These results attest to the effectiveness of learning at the emulation and self-control levels and are discussed with reference to the social cognitive model of self-regulation development.     

Prior self-control exertion and perceptions of pain during a physically demanding task

ObjectivesExertion of self-control has been associated with impaired performance on subsequent physical tasks also requiring self-control, but it remains unknown why this occurs. This study, therefore, explored whether a) prior self-control exertion reduces subsequent persistence on a physically demanding task, and b) whether any observed performance decrements could be explained by changes in perceptions of pain.MethodIn a within-subject design, sixty-three individuals completed an easy (congruent) Stroop task or a difficult (incongruent) Stroop task that required self-control. Participants were then required to remain in a physically demanding posture (i.e., a ‘wall-sit’) until voluntary exhaustion and their perception of pain was recorded during the task.ResultsWhen participants completed the difficult Stroop task, they quit the wall-sit sooner. This decrement in performance was explained by greater perceptions of pain at the beginning of the wall-sit.ConclusionsPerceptions of pain may, therefore, be an important attentional mechanism explaining why self-control use interferes with subsequent persistence during physically effortful tasks.     

Self-regulated learning in physical education: Examining the effects of emulative and self-control practice

Objective

This study examined the effectiveness of sequential practice from the emulation to the self-control level of the social cognitive model of self-regulated learning development. The model proposes that students who practice with social feedback at the emulation level first and then set goals and self-record their performance at the self-control level master sport skills effectively.

Design

The design included one between-subjects factor, the group with five levels and one within-subjects factor, time (pre-test, post-test).

Method

One hundred fifth and sixth grade students (40 boys and 60 girls) were assigned to four experimental and one control group and practiced the basketball dribble.

Results

The results showed that students of all experimental groups improved their dribbling performance from pre- to post-test. Students who received social feedback and observed repeated demonstrations at the emulation level and then set process or performance goals and self-recorded their performance at the self-control level improved their dribbling performance more than students who missed emulative practice. No improvement was found for control group students.

Conclusions

These results supported the effectiveness of the social cognitive model of self-regulated learning development, showing that this model can be used as an instructional approach for teaching sport skills in physical education.     

Individual differences in ego depletion: The role of sociotropy-autonomy

In his cognitive theory of depression, Beck (1987) suggested that highly sociotropic individuals have a strong need for social acceptance whereas highly autonomous individuals have an excessive need for achievement. Research by Baumeister (2000) has suggested that a phenomenon known as ego depletion, the weakening of performance on tasks following active self-control, occurs because it depletes a limited inner resource. The present study examined whether individuals who are highly sociotropic or autonomous would respond differently when faced with tasks requiring self-control. Participants completed the Sociotropy-Autonomy Scale (Clark et al. 1995) and engaged in two active self-control tasks. The results revealed that sociotropy levels were negatively correlated with persistence on tasks that require self-control whereas autonomy was positively correlated to persistence on the same task. In addition, the results suggested that, following a task requiring self-control, highly sociotropic individuals expend less effort, whereas highly autonomous individuals expend more effort on subsequent tasks requiring self-control.     

The voice of self-control: Blocking the inner voice increases impulsive responding

Philosophers and psychologists have long-debated the notion that the voice in our heads might help us to control our actions. Evidence from a number of lines of research suggests that verbal resources help us to focus attention, providing reason to believe that the inner voice might aid self-control via this capacity. In this study we explored the link between verbal resources and self-control by occupying the inner voice and then assessing behavioral indices of self-control. Participants completed regular and switching versions of the Go/No-Go task while doing verbal or spatial secondary tasks. Compared with the spatial task, doing the verbal task resulted in more impulsive responding, as indicated by a greater tendency to make a ‘Go’ response, a pattern that was accentuated in the switching version of the Go/No-Go. Our results suggest that the inner voice helps us to exert self-control by enhancing our ability to restrain our impulses.     

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.     

Lack of autonomy and self-control: Performance contingent rewards lead to greater depletion

Exerting self-control appears to deplete a needed resource, which leads to poorer self-control subsequently. However, the amount of depletion may vary, based on how controlling versus autonomy supportive the situation is. In particular, feeling compelled to exert self-control may deplete more strength than having more freedom when exerting self-control. In three experiments, participants who were given performance contingent rewards to exert self-control performed more poorly on a subsequent test of self-control than participants who were non-contingent rewards. There were no differences in mood, arousal, or anxiety between the groups; however, feelings of autonomy were related to self-control performance. The results have implications for understanding self-control depletion, as well as the impact of autonomous motivation on self-control performance.

Superiority of variable to repeated practice in transfer on anagram solution

Previous research in motor learning shows that practicing variations of a task (variable practice) leads to better transfer than does repeatedly practicing the exact same task (repeated practice). In contrast, research on priming using verbal materials shows that performance on a test improves to the extent that the material at learning and test overlap. We tested whether variability in practice conditions can lead to improved performance with the verbal priming task of anagram solution. Participants practiced solving anagrams, either repeatedly solving the same anagram that was later tested, repeatedly solving a different anagram from the one that was later tested, or solving different variations of the anagram that was later tested. We found that this last condition-variable practice on different versions of an anagram-led to improved test performance in relation to repeated practice, even when the test anagram was the one that had been repeatedly practiced. This finding aligns results from the motor learning literature with a higher level cognitive task: anagram solution. Shea and Kohl's (1991) hypothesis, arguing that varied practice may lead to greater elaborative processing than does repeated practice, provides one account of the results.     

The Association Between Self-Control and Hoarding: A Case Report

The capacity to exert control over one's behavior is known as self-control, and this ability to self-regulate is a necessary component for directing personal behavior toward achieving a specific goal. Baumeister and colleagues have suggested that self-control operates within a resource model such that an individual may strengthen this resource through directed practice. Hoarding is one syndrome wherein self-control may play a substantial role. Within a translational research framework, two separate case studies sought to determine if practicing self-control in a non-hoarding-related domain might have an impact on an individual's hoarding symptoms and their readiness for treatment. Two individuals diagnosed with hoarding were enrolled in a self-control practice condition. Both self-control levels and hoarding symptoms were measured at pre– and post–time points using self-report and behavioral indices. Findings in support of a favorable effect of self-control on mitigating behavioral hoarding symptoms were mixed, with 1 patient experiencing marked improvement in symptoms and the other not. We also found that self-control practice was associated with both increased motivation for treatment and overall level of self-awareness. The implications of self-control for hoarding are discussed from a disease-reduction and prevention standpoint, along with the role self-control might play within more traditional cognitive behavioral interventions.     

Ego depletion improves insight

Initial acts of self-control can reduce effort and performance on subsequent tasks – a phenomenon known as ego depletion. Ego depletion is thought to undermine the capacity or willingness to engage executive control, an important determinant of success for many tasks. We examined whether ego depletion improves performance on a task that favours less executive control: insight problem solving. In two experiments, participants completed an ego-depletion manipulation or a non-depleting control condition followed by an insight problem-solving task (i.e., matchstick arithmetic). Participants in the depleting condition demonstrated greater insight problem-solving accuracy than those in the non-depleting control condition. Priming theories of willpower did not impact these results. Although ego depletion is widely regarded as a “state of impairment”, attendant decreases in executive control may foster insightful thinking.     

Autonomous Self-Control is Less Depleting

Autonomously motivated self-control may be less depleting than extrinsically motivated self-control. Participants were asked to not eat cookies and their motivation orientation for resisting that temptation was assessed. Their self-control performance was assessed immediately before and after fighting the temptation. As compared to their baseline performance, participants who avoided eating the cookies for more autonomous reasons performed better at the second measure relative to participants who did not eat for more extrinsic reasons. Mood, arousal, and demographic factors were not related to self-control performance and feelings of autonomy. Overall, it appears that feeling compelled to exert self-control may deplete more strength than having more freedom when exerting self-control. The results may increase our understanding of how self-control strength and feelings of autonomy interact.     

Motivation,personal beliefs,and limited resources all contribute to self-control

What effects do motivation and beliefs have on self-control? We tested this question using a limited resource paradigm, which generally has found that people show poor self-control after prior exertions of self-control. Recent findings have suggested that motivation and even belief in unlimited willpower can render persons immune to ego depletion. We replicated those findings, but also showed they are limited to cases of mild depletion. When depletion is extensive, the effects of motivation and subjective belief vanished and in one case reversed. After performing only one self-control task, the typical pattern of self-regulation impairment was ameliorated among people who were encouraged to regard willpower as unlimited (Experiment 1) or motivated by task importance (Experiment 2). Those manipulations failed to improve performance among severely depleted persons who had done multiple self-control tasks. These findings integrate ideas of limited resources, motivation, and beliefs in understanding the nature of self-control over time.     

A preliminary analysis of self-control with aversive events: the effects of task magnitude and delay on the choices of children with autism

When faced with a choice between two aversive events, a person exhibits self-control by choosing a smaller, more immediate aversive event over a larger, delayed aversive event. Task demands are often aversive to children with autism and other developmental disabilities. The purpose of this study was to evaluate behavioral sensitivity to differences in the amount and delay of tasks as part of a preliminary study on self-control. Participants were 2 children with autism who engaged in problem behavior maintained by escape. Results indicated a lack of self-control with respect to choosing between two aversive tasks and suggested potential strategies for increasing self-control (i.e., choosing a small immediate task over a large delayed task).
