自我损耗促进冲动决策：来自行为和ERPs的证据

该研究以自我控制资源模型为理论框架, 采用行为实验和ERPs技术考察自我损耗对冲动决策的影响。实验1采用Stroop任务操纵自我控制资源并采用延迟折扣任务考察被试的决策冲动性, 实验2采用同样的实验任务并同时采用ERPs技术记录高、低自我损耗者在随后决策任务中的脑电成分。行为结果发现, 在控制心境、特质自我控制水平以及风险偏好等无关变量后, 高损耗者比低损耗者在延迟折扣任务上的折扣程度更大。ERPs结果发现, 不论延迟金额大小, 高损耗者在左侧额区诱发的N1波幅显著小于低损耗者; 高损耗者在右半球诱发的P2波幅显著大于低损耗者。研究表明, 自我损耗抑制决策早期左侧额区的激活水平, 个体因而无法识别冲突以及抵制即时满足的诱惑, 这促使他们采用直觉启发式进行决策, 最终导致冲动决策的产生。     

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。     

自我损耗下积极情绪对亲社会行为的影响

基于自我控制资源理论,本研究通过2个递进实验探究自我损耗下积极情绪对亲社会行为的影响。实验1采用“非利手写作”任务操纵被试的自我损耗,并诱发积极情绪,以被试在独裁者任务中分配的代币数为亲社会行为的衡量指标。结果发现：相比于低损耗组,高损耗组亲社会行为水平更低;诱发积极情绪能够补偿自我控制资源。实验2在此基础上,诱发高、低趋近动机积极情绪,考察自我损耗状态下不同强度趋近动机积极情绪对亲社会行为的影响。结果表明,低趋近动机积极情绪能缓解自我损耗后效。本研究证实了提高自我损耗将降低个体亲社会行为水平,诱发低趋近动机积极情绪可以缓解该效应。     

自我损耗、情绪动机对冲动决策的影响

以大学生为被试,探讨自我损耗、情绪动机对冲动决策的影响。采用2×2×2的混合实验设计,组内变量为自我损耗,组间变量为情绪动机方向和强度,使用双任务范式操作自我损耗,使用情绪动机图片启动被试的情绪动机,使用延迟折扣任务的指标k值测量冲动决策。结果发现,高趋近动机的k值大于低趋近动机,高回避动机的k值大于低回避动机。结果表明,自我损耗、情绪动机对冲动决策有明显影响。     

自我损耗对运动表现影响的元分析

运用元分析方法考察自我损耗对运动表现影响及其调节变量。通过中英文文献搜索,共纳入31篇文献和37个效应量,总样本量为1613。结果:(1)总体效应量检验发现,运动任务中的自我损耗为中等效应量,d=0.55,95%CI为[0.39,0.71];由于存在发表偏倚性,该中等效应量可能会被高估。(2)调节变量检验发现,自我损耗效应量较少受研究对象来源、研究对象类型和运动任务类型的影响;但受损耗任务类型和技能型任务中压力情境的影响。(3)执行运动任务时,主观体力感、心率和肌电等指标不存在自我损耗效应。这些研究结果支持了自我控制的力量模型具有普遍适用性,自我控制资源的领域普遍性以及自我控制的力量模型与注意控制理论整合的观点。未来研究应严格控制实验条件、拓展运动任务中自我损耗应对和自我控制训练的研究。     

双系统模型视角下的罪犯自我控制

自我控制是个体为了达成具有长远利益的目标而有意识控制自身冲动行为的能力。双系统模型提出自我控制系统包含冲动系统与控制系统, 该理论适用于分析罪犯低自我控制的内部结构。罪犯冲动系统中充满极易激活的犯罪相关行为图式, 而控制系统却不足以生成抑制冲动行为的策略。未来可基于双系统模型, 整合已有研究深入考察罪犯自我控制系统的内部运作机制, 以及该模型在罪犯心理矫治中的实际应用, 而犯罪易感青少年群体则需要特别关注。     

自我损耗对工作场所安全的影响及缓解途径

员工安全行为是工作场所安全的重要保障,而自我控制资源损耗会对安全行为产生负面影响。研究拟借鉴自我控制资源有限模型,结合行为和生理指标,探讨工作要求和辱虐管理通过损耗个体自我控制资源对安全行为的影响,并从特质自我控制和自动化安全趋近倾向两个角度探索上述效应的缓解机制。此外,研究拟采用心率变异性作为自我损耗的生理测量。研究有助于从自我控制资源的角度理解员工不安全行为的影响因素、发生机制和缓解方法。     

利用无意识目标启动降低个体的冲动购买行为：个体目标状态的调节作用

冲动购买会给个体和社会带来诸多不良影响,而探讨如何降低冲动购买的研究报道却很少。此外,仅有的少数研究都是从提升自我控制能力的角度来开展,其干预方法具有一定的局限性。本研究从提升自我控制的动机角度出发,考察利用无意识目标启动能否降低冲动购买,并考察其适用条件。研究发现,无意识目标启动可以显著降低有省钱目标个体的冲动购买行为,而对无省钱目标个体的冲动购买行为没有显著影响。本研究结果提示,无意识目标启动有希望成为一种简单、便捷的降低冲动购买行为的有效干预方式,特别是对有省钱目标的个体而言。

自我损耗促进冒险行为

基于自我控制资源模型,本研究探讨了自我损耗对冒险行为的影响以及生理能量补充在其中的缓解作用。实验1和实验2分别通过“Stroop”和“非利手写作”任务操纵被试的自我损耗,两个实验均用气球模拟风险决策任务考察被试的冒险行为,并且通过摄入含有或不含有葡萄糖的柠檬水来操纵生理能量水平。结果发现,在排除无关变量后,高损耗者比低损耗者尽可能多地对气球进行充气以寻求奖赏(实验1和实验2),但饮用含葡萄糖的柠檬水能够有效降低这种反应(实验2)。该研究证实了自我损耗促进冒险行为,补充生理能量能有效缓解该效应。     

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.     

Future Selves and Self-Control Motivation

Self-control is well established as a predictor of crime and deviance. Little is known, however, about the motivation to exert self-control, or the degree to which individuals perceive self-control to be relevant or necessary. This is because the “self” in self-control theory is under-theorized. We argue that self-control over criminal and deviant behavior is influenced by the desired and feared conceptions people have of themselves in the future. We argue that people's projections of their future selves engender commitments to lines of action, which mobilize the motivation to exercise self-control. By developing a more detailed conception of the “self” in self-control theory, we hope to orient criminology more fully to the importance of individuals' projected future selves and intended lines of action for understanding the relationship between self-control and criminal behavior.     

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.     

A Cognitive Control Perspective of Self-Control Strength and Its Depletion

Self-control strength is a central construct to theories of willpower, optimal functioning, freedom from addiction, and abilities to override problematic social motives and behaviors (e.g., aggression). Understanding the processing basis of self-control strength, and more particularly its depletion, is thus of paramount importance to both basic and applied literatures. Self-control strength, the present review suggests, can be profitably viewed in cognitive control terms, particularly so in relation to operations of a brain-based cognitive control circuit involving the anterior cingulate cortex (linked to monitoring potential or actual unwanted outcomes) and the dorsolateral prefrontal cortex (linked to controlling potential or actual unwanted outcomes). Also, sufficient task motivation is important to operations of this circuit and depletion effects might be understood in terms of such depletion effects on task motivation. Multiple sources of evidence are marshaled in support of this cognitive control perspective of self-control strength. It is concluded that viewing self-control strength in cognitive control terms has considerable merit. Social, cognitive, personality, and clinical sources of data are integrated in the analysis.

“Pay the piper”: It helps initially,but motivation takes a toll on self-control

ObjectiveTo investigate the aftereffects of anticipating future self-control and motivation on self-control strength depletion patterns.DesignSingle blind, randomized 2 (autonomy-supportive motivation/controlling motivation) × 2 (anticipation/no anticipation) factorial.MethodParticipants (N = 72) performed four sequential self-control strength challenges: an initial endurance handgrip squeeze followed by the Stroop task and two additional endurance handgrip squeezes. A sequential randomization procedure was used to allocate participants to one of four conditions: anticipation/autonomy-supportive motivation (n = 19), anticipation/controlling motivation (n = 17), no anticipation/autonomy-supportive motivation (n = 18), and no anticipation/controlling motivation (n = 18).ResultsParticipants who anticipated future self-control depletion conserved resources on the second task by completing fewer words on a Stroop task compared to controls. Participants who received autonomy-supportive instructions performed significantly better than controls on a third task (endurance handgrip squeeze), but worse than controls on the fourth task (another endurance handgrip squeeze). There were no significant interactions between anticipation and motivation (p > .05).ConclusionsResults support previous findings reflecting conservation and motivation effects on self-control strength. This was the first study to show that autonomy-supportive instructions may assist self-control performance in the short term but ultimately depletes self-control strength and impairs performance in the long term.     

自我损耗的研究方法述评

自我控制是个体成功的重要因素,但个体在自我控制的同时,也要为每次控制付出代价,产生自我损耗,导致随后自我控制的失败。本文回顾了双任务范式中诱发、测量、克服自我损耗的方法,认为未来研究应探索任务的有效性、多采用三任务范式等,在克服自我损耗方面,应同时关注短期克服损耗的方法和提高整体控制能力的方法。     

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.     

Self-control trumps work motivation in predicting job search behavior

Current labor market entrants face an increasingly challenging job search process. Effective guidance of job seekers requires identification of relevant job search skills. Self-control (i.e., the ability to control one's thoughts, actions, and response tendencies in view of a long-term goal, such as finding employment) is assumed to be one such relevant job search skill. The current study is the first to empirically assess the importance of self-control in the job search process. This is compared to the role of motivation, which is generally considered a crucial predictor of job searching. Based on a sample of 403 Dutch prospective vocational training graduates, we found that higher levels of self-control were related to higher levels of preparatory job search behavior and job search intentions half a year later, shortly before labor market entrance. Self-control was a significantly stronger predictor of job searching than work motivation. Moreover, relations between self-control and job searching were largely independent of motivation, which may suggest that job-seekers benefit from self-control through adaptive habits and routines that are unaffected by motivation. We propose that job search interventions, which traditionally focus on strengthening motivation, may benefit from a stronger focus on improving self-control skills.
