Self-directed weight control through eating and exercise

A weight control program using a written contract and other self-control behavior modification techniques for changing eating habits was compared with a similar program concentrating on both eating and exercise behavior and with an attention-placebo control condition. Participants in all three programs lost weight during the 12 week program, with no significant differences between groups. A seven-month follow-up revealed that Ss in the two behavior modification groups lost more than those in the control group and that those in the eating plus exercise group lost more than those in the group dealing only with eating behavior.     

Self-control of feedback during motor learning: accounting for the absolute amount of feedback using a yoked group with self-control over feedback

A traditional control group yoked to a group that self-controls their reception of feedback receives feedback in the same relative and absolute manner. This traditional control group typically does not learn the task as well as the self-control group. Although the groups are matched for the amount of feedback they receive, the information is provided on trials in which the individual may not request feedback if he or she were provided the opportunity. Similarly, individuals may not receive feedback on trials for which it would be a beneficial learning experience. Subsequently, the mismatch between the provision of feedback and the potential learning opportunity leads to a decrement in retention. The present study was designed to examine motor learning for a yoked group with the same absolute amount of feedback, but who could self-control when they received feedback. Increased mental processing of error detection and correction was expected for the participants in the yoked self-control group because of their choice to employ a limited resource in the form of a decreasing amount of feedback opportunities. Participants in the yoked with self-control group committed fewer errors than the self-control group in retention and the traditional yoked group in both the retention and time transfer blocks. The results suggest that the yoked with self-control group was able to produce efficient learning effects and can be a viable control group for further motor learning studies.     

Longitudinal improvement of self-regulation through practice: building self-control strength through repeated exercise.

This study examined the results of repeated exercises of self-control in relation to self-regulatory strength over time. A sample of 69 U.S. college students spent 2 weeks doing 1 of 3 self-control exercises: monitoring and improving posture, regulating mood, or monitoring and recording eating. Compared with a no-exercise control group, the participants who performed the self-control exercises showed significant improvement in self-regulatory capacity as measured by quitting faster on a hand-grip exercise task following a thought-suppression exercise.     

Self-control over combined video feedback and modeling facilitates motor learning

Allowing learners to control the video presentation of knowledge of performance (KP) or an expert model during practice has been shown to facilitate motor learning (Aiken, Fairbrother, & Post, 2012; Wulf, Raupach, & Pfeiffer, 2005). Split-screen replay features now allow for the simultaneous presentation of these modes of instructional support. It is uncertain, however, if such a combination incorporated into a self-control protocol would yield similar benefits seen in earlier self-control studies. Therefore, the purpose of the present study was to examine the effects of self-controlled split-screen replay on the learning of a golf chip shot. Participants completed 60 practice trials, three administrations of the Intrinsic Motivation Inventory, and a questionnaire on day one. Retention and transfer tests and a final motivation inventory were completed on day two. Results revealed significantly higher form and accuracy scores for the self-control group during transfer. The self-control group also had significantly higher scores on the perceived competence subscale, reported requesting feedback mostly after perceived poor trials, and recalled a greater number of critical task features compared to the yoked group. The findings for the performance measures were consistent with previous self-control research.     

游戏训练提高幼儿自我控制能力:来自ERP的证据

游戏是激发幼儿兴趣的有效载体,已有研究表明游戏可以提高幼儿自我控制的外显行为表现,但未考察是否能够引起幼儿自我控制相关的电生理变化。本研究将幼儿按班级随机分为实验组和对照组,实验组的幼儿接受一学期的游戏训练,对照组不参加训练,进行自由活动,训练前后所有幼儿完成Go/No Go任务的ERP测试,评定自我控制能力。结果发现:实验组后测中No Go任务的N2和P3成分(分别表示为No Go-N2和No Go-P3)平均波幅均显著小于前测,而对照组前后测波幅无变化;同时,后测实验组中No Go-N2平均波幅显著小于对照组。结果表明,游戏训练可促进幼儿自我控制相关大脑系统的发展,为自我控制游戏训练的效果提供了电生理证据。。     

The use of a self-control package to enhance temporal generality of a parent training program

The purpose of the present study was to examine the effectiveness of a self-control package in enhancing temporal generality of a parent training program. Sixteen mothers and their clinic-referred noncompliant children were assigned to either a parent training alone group, or a parent training plus self-control group. All mother-child dyads were treated individually by teaching the mother to reward compliance and other prosocial behavior, and to use time-out for noncompliance. In addition, mothers who also received self-control training learned to self-monitor their use of their new parenting skills and to reinforce themselves for use of the skill during a 2 month follow-up period. Assessment consisted of four home observations by independent observers prior to treatment, after treatment, and at a 2 month follow-up. The data indicated that the children in the parent training plus self-control group were significantly more compliant and less deviant at the 2 month follow-up than the children in the parent training alone group. Parental behavior did not differ between the two groups at the follow-up.     

Behavioral self-control of on-task behavior in an elementary classroom

Techniques of behavioral self-control were employed in a class where a high level of on-task behavior had been established with externally administered reinforcement procedures. The behavioral self-control techniques maintained behavior at its ongoing high level both immediately following the externally administered reinforcement treatments and during follow-up treatments after five and seven weeks. Variability in on-task behavior was reduced during the behavioral self-control phases of the study.     

Self-control relies on glucose as a limited energy source: willpower is more than a metaphor

The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.     

Self-control and accommodation in close relationships: an interdependence analysis

Accommodation refers to the willingness, when a partner has engaged in a potentially destructive behavior, to (a) inhibit impulses toward destructive responding and (b) instead respond constructively. A pilot study and 3 additional studies examined the hypothesis that self-control promotes individuals' ability to accommodate in response to a romantic partner's potentially destructive behavior. Dispositional self-control was positively associated with accommodative tendencies in all 4 investigations. In addition, Study 1 (a retrospective study) and Study 2 (a laboratory experiment) revealed that "in-the-moment" self-regulatory strength depletion decreased the likelihood that an individual would accommodate. Finally, Study 3 demonstrated that self-control exerted a significant effect on accommodation even after the authors included commitment to the relationship in the model. Implications for relationship functioning are discussed.     

Effects of preexisting and manipulated self-efficacy on weight loss in a self-control program

The present study was designed to investigate the effects of self-efficacy on weight loss utilizing self-control techniques. Subjects high and low in preexisting self-efficacy were randomly assigned to high or low manipulated self-efficacy groups in a 2 × 2 (preexisting self-efficacy × manipulated self-efficacy) factorial design. Preexisting self-efficacy was assessed using procedures employed byBandura and Adams (1977, Cognitive Therapy and Research, 1, 287–308). Selfefficacy was manipulated by having subjects attribute successful task performance to a previously unrecognized capacity for self-control. Subjects met in groups once a week for a total of 8 weeks and received a comprehensive weight control program within the context of self-control. Results indicated significant manipulated and preexisting × trials interactions with both the high manipulated and preexisting self-efficacy groups losing more weight over the 8 weeks than the low preexisting and manipulated groups. In addition, locus of control was predictive of weight loss, with internals tending to lose more weight than externals. Results are discussed in terms of Bandura's (1977, Psychological Review, 84, 191–215) theory of self-efficacy.     

Relationships between mindfulness, self-control, and psychological functioning

The purpose of this study was to investigate whether dispositional mindfulness (the tendency to be mindful in general daily life) accounts for variance in psychological symptoms and wellbeing after accounting for the influence of dispositional self-control (the tendency to be self-disciplined, reliable, hardworking, etc.). A large sample of undergraduate students (N = 280) completed self-report measures of mindfulness, self control, psychological wellbeing, and general psychological distress (depression and anxiety, and stress). As expected, both mindfulness and self-control were positively correlated with wellbeing and negatively correlated with general distress. Mindfulness was found to account for significant variance in psychological wellbeing and general distress after accounting for self-control. In addition, mindfulness was a significant moderator of the relationship between self-control and psychological symptoms. Results show that although self-control predicts significant variance in psychological health, mindfulness predicts incremental variance, suggesting that a mindful approach to ongoing experience can contribute to mental health in persons who are highly self-disciplined and hardworking.     

Digital piracy: an examination of low self-control and motivation using short-term longitudinal data.

The purpose of the present study was to examine the link between low self-control, motivation, and digital piracy. This study used short-term longitudinal data (i.e., once a week for 4 weeks) from undergraduate students (n = 292) and latent trajectory analysis. The results of this study revealed that the students had significant variability in initial levels and rates of change in digital piracy. The results indicated that whether motivation was treated as a time-invariant or time-varying measure, it along with sex (i.e., being male) had a significant link with the initial levels of digital piracy and that sex and low self-control had links with the rate of change. These results are discussed, and policy implications are made.     

Self-control training decreases aggression in response to provocation in aggressive individuals

One common cause of aggression is self-control failure, yet research suggests that practicing self-control over time can improve subsequent self-control. This experiment tested whether self-control training over a 2-week period could decrease anger and aggression in response to provocation. Seventy undergraduates completed 2 weeks of self-control training or a control task. At the end of the 2 weeks, participants were insulted and given the opportunity to retaliate by delivering a blast of loud white noise. Self-control training reduced aggression among those high in trait aggression. Participants who received the training also reported less anger than those in the control condition. These results provide initial support that self-control training might prove beneficial for assisting aggressive individuals to overcome aggressive impulses.     

Exchange delays and impulsive choice in adult humans.

Choice responding by adult humans in a discrete-trial task was examined as a function of conditions that manipulated either the delay to point delivery or the delay between points and their exchange for money. In point-delay conditions, subjects chose between an "impulsive" alternative that provided a small amount of points immediately and a "self-control" alternative that provided a larger amount of points delayed by 15, 30, or 60 s. Points were exchanged for money immediately following the session. Subjects preferred the self-control alternative. In exchange-delay conditions, subjects chose between a small amount of points exchangeable for money immediately following the session and a larger amount of points exchangeable for money after 1 day, 3 weeks, or 6 weeks. A self-control preference observed for all subjects in the 1-day exchange-delay condition reversed to exclusive impulsive preference for 4 of the 6 subjects when choice conditions involved exchange delays of 3 or 6 weeks. These results show that human choice is sensitive to the manipulation of exchange delays and that impulsive preference can be obtained with exchange delays on the order of weeks.     

In the trenches of real-world self-control: neural correlates of breaking the link between craving and smoking

Successful goal pursuit involves repeatedly engaging self-control against temptations or distractions that arise along the way. Laboratory studies have identified the brain systems recruited during isolated instances of self-control, and ecological studies have linked self-control capacity to goal outcomes. However, no study has identified the neural systems of everyday self-control during long-term goal pursuit. The present study integrated neuroimaging and experience-sampling methods to investigate the brain systems of successful self-control among smokers attempting to quit. A sample of 27 cigarette smokers completed a go/no-go task during functional magnetic resonance imaging before they attempted to quit smoking and then reported everyday self-control using experience sampling eight times daily for 3 weeks while they attempted to quit. Increased activation in right inferior frontal gyrus, pre-supplementary motor area, and basal ganglia regions of interest during response inhibition at baseline was associated with an attenuated association between cravings and subsequent smoking. These findings support the ecological validity of neurocognitive tasks as indices of everyday response inhibition.     

Self-control behaviors during the learning of a cascade juggling task

This study examined the self-control behaviors of participants learning a 3-ball cascade juggle. Participants chose when they would receive one of four types of instructional assistance: (a) instructions; (b) video demonstration; (c) knowledge of performance (KP); and (d) knowledge of results (KR). Juggling proficiency was divided into three categories based on catches per attempt during retention and transfer testing. In general, participants decreased their requests for instructions and video demonstration throughout acquisition. For the most proficient performers, requests for KR increased over practice. Post-experimental interviews revealed that participants requested KR after primarily good attempts and KP after both good and bad attempts. Participant-reported reasons for requesting feedback included the confirmation of success (KR) and identification of technique flaws (KP). Overall, the findings suggest that self-control behaviors are more complex than previously demonstrated and that participants use self-control differently depending upon the type of assistance available, individual preferences, and learning needs.     

THE EXPERIMENTAL MODIFICATION OF SONOROUS BREATHING

Loud snoring is a noxious habit and potential personal health risk. We are reporting the first experimental study of simple behavioral techniques for the modification of chronic snoring. Twenty-four volunteers participated in a repeated measures, randomized group design over 2 weeks of intervention and one-month follow-up. Treatment groups included a contingent-awakening and breathing retraining (self-control) condition. Both treatment groups were compared to a no-treatment control. Despite considerable intrasubject variability and the lack of an adequate attention-placebo control group, objective assessment indicated a substantial reduction in snoring amplitude and frequency in both treatment groups. Follow-up assessments further demonstrated maintenance of change. This study has implications for modification of sleep habit disorders and learning without awareness.     

Reducing self-control by weakening belief in free will

Believing in free will may arise from a biological need for control. People induced to disbelieve in free will show impulsive and antisocial tendencies, suggesting a reduction of the willingness to exert self-control. We investigated whether undermining free will affects two aspects of self-control: intentional inhibition and perceived self-control. We exposed participants either to anti-free will or to neutral messages. The two groups (no-free will and control) then performed a task that required self-control to inhibit a prepotent response. No-free will participants showed less intentional inhibitions than controls, suggesting a reduction of self-control. We assessed perceived self-control by asking participants whether the response resulted from a deliberate intention or from an impulsive reaction. Perceived self-control was lower in the no-free will group than in control group. Our findings show that undermining free will can degrade self-control and provide insights into how disbelieving in free will leads to antisocial tendencies.     

欺骗判断与欺骗行为中自我控制的影响

欺骗判断与欺骗行为有着不同的心理机制, 正确认识二者之间的关系有助于增强人际间的信任和团队的长远利益。采用行为学实验从两种视角下考察自我控制对欺骗的影响。实验1采用材料评定的方法考察了识别他人自我控制能力状况对欺骗判断的影响, 结果发现对比高自我控制能力的人, 被试更倾向于认为低自我控制能力的人更有可能为了自己的利益产生欺骗行为和欺骗倾向。实验2采用颜色Stroop任务考察了识别他人自我控制资源衰竭状况对欺骗判断的影响, 结果发现当识别他人自我控制资源衰竭时, 在评价他人为自己利益去欺骗、为他人利益去欺骗以及在特定情境中欺骗倾向上, 没有发现任何显著的主效应或交互作用。实验3采用视觉−感知任务来考察不同水平的自我控制能力对欺骗行为的影响, 结果发现, 对比高自我控制组, 低自我控制组有更多的欺骗行为和欺骗倾向。实验4采用颜色Stroop任务和视觉−感知任务来考察自我控制资源对欺骗行为的影响, 结果发现, 对比控制组, 自我控制资源衰竭组有更多的欺骗行为和欺骗倾向。这些研究结果表明, 在进行欺骗判断时, 相比自我控制资源状况, 个体会优先识别他人的自我控制能力水平来判断其是否具有欺骗动机或欺骗倾向。在欺骗行为中, 高自我控制能力的个体, 能够更好地抑制自私动机, 更多的考虑长远利益, 出于自身利益去欺骗的可能性会更小; 自我控制资源充足的个体, 更有可能会经得住诱惑, 自私自利的欺骗行为发生的可能性也会更小。     

The Role of Perspective Taking and Self-Control in a Preventive Intervention Targeting Childhood Disruptive Behavior

Prevention studies typically focus on outcome variables such as reductions in problem behavior, rather than targeted factors (e.g., cognitions), or the relation between change in targeted factors and outcomes. Therefore, the current study examined the effect of a targeted prevention program for childhood disruptive behavior on targeted factors (i.e., perspective taking and self-control) and associations between change in targeted factors and outcomes (i.e., aspects of disruptive behavior). The sample consisted of 173 children (Mage?=?10.2 years) who were randomly assigned to an intervention condition (n?=?70) or waitlist control condition (n?=?103). Assessment took place at pre-, post- and follow-up measurements. For ethical considerations, follow-up data was not available for children on the waitlist. Findings revealed a direct intervention effect on self-control. From pre-test to follow-up, children who received the intervention improved in perspective taking and self-control. Moreover, improvements in self-control were associated with and predicted reductions in teacher-reported symptoms of oppositional defiant disorder. No associations were found between changes in perspective taking and disruptive behavior. These findings suggest that self-control may be an important target factor in reducing childhood disruptive behavior in targeted prevention.
