自我控制的内涵:基于资源模型与双系统模型的解释

自我控制是人们克服冲动、习惯或自动化反应,有意识地掌控自己行为的能力。在人类的进化过程中,自我控制能力的出现使得人们走出了荒蛮时代,使人类在物种进化的大军中脱颖而出。对于自我控制的研究目前最有代表性的理论分别是自我控制资源模型和自我控制的双系统模型。这两种模型从不同的角度对自我控制进行了阐述和研究,两者的角度虽然不同,但通过对两种理论的解读可以发现两者之间存在着密不可分的联系,这可以帮助我们更为深入了理解自我控制的内涵机制。     

大学生手机成瘾与学习投入的关系:自我控制的中介作用和核心自我评价的调节作用

为考察手机成瘾、自我控制、核心自我评价和学习投入之间的关系,本研究采用手机成瘾量表、自我控制双系统量表、核心自我评价量表以及学习投入量表对628名大学生进行问卷调查。结果显示：（1）手机成瘾可以负向预测大学生学习投入;（2）控制系统和冲动系统在手机成瘾与学习投入的关系中起并行中介作用;（3）手机成瘾对学习投入的直接预测作用受到核心自我评价的调节。研究结果揭示了手机成瘾对学习投入的作用机制,拓展了核心自我评价的研究视角,对于学习投入的干预工作有一定实践意义。     

自我控制的力量模型

自我控制是人们克服冲动、习惯或自动化的反应,有意识地掌控自己行为方向的能力。自我控制的力量模型认为自我控制的执行会消耗有限的心理能量。力量模型的证据主要来自冲动行为、人际交互以及决策和判断等领域的研究,影响自我控制力量的因素包括人格和个体差异、情绪和动机以及自我控制训练等。自我损耗与疲劳感的区别、动机和信念在自我损耗中的作用以及力量模型的应用价值等是未来研究值得关注的问题。     

特质焦虑与青少年冒险行为的关系：基于双系统模型的机制探讨

为了考察特质焦虑与青少年冒险行为的关系并基于双系统模型探究其中的影响机制,本研究采用特质焦虑问卷、简版自我控制量表、感觉寻求量表和青少年多领域冒险行为问卷对1720名12～18岁的青少年进行问卷调查,共回收有效数据1549份。结果发现：（1）特质焦虑能正向预测青少年的冒险行为,自我控制在特质焦虑与冒险行为间的关系中起中介作用;（2）感觉寻求调节了该中介过程的后半路径,即个体的感觉寻求水平越高,自我控制对冒险行为的预测作用越大。     

青少年高冒险行为与大脑发展

青少年时期是一个转折期,也是冒险行为多发的时期。以往有关青少年冒险行为的研究大多集中在心理学视角与社会关系学视角,双系统竞争理论从生物学视角对青少年高冒险行为作出解释。该理论认为青少年高冒险行为的产生主要是由于大脑中的社会情绪系统与认知控制系统相互竞争作用的结果。社会情绪系统对奖赏寻求起作用,而认知控制系统对执行功能起作用。较早发展的社会情绪系统与较晚才成熟的认知控制系统间的竞争是青少年冒险行为产生的原因。     

身体活动的双系统理论:一种强化学习的视角

以理性决策为基础的锻炼行为理论被认为是理解身体活动的主导体系, 它提供了与身体活动相关的认知构念作为有价值的信息。基于社会生态模型设计的行为干预措施, 因表现出了更好的效果而备受关注。近期研究表明, 积极的运动认知和当前体育环境都没能很好地促进个人锻炼习惯的养成, 因此有必要探索新的理论体系来阐明个人锻炼习惯的形成机制。解释身体活动的最新体系是双系统理论, 由于其考虑了身体活动的无意识和快乐决定因素, 有望提供一个更广泛的动机视角。一方面, 多个有代表性的身体活动双系统模型, 从简单的自发路径, 到情境线索与锻炼习惯, 再到突出自动情感评价作用的复杂概念模型, 阐明了系统1的构建, 结合锻炼行为理论所关注的系统2, 为模型的构建提供了依据。另一方面, 通过对双系统的竞争、协调和层级控制原则的分析, 为模型的控制提供了建议。经典的强化学习框架解释了双系统模型的构建与控制原则:在模型的构建方面, 无模型与基于模型的强化学习分别表示系统1和系统2。在模型的控制方面, Dyna协作架构与分层强化学习, 为身体活动可能是一种相互协作、分层执行的复杂行动组合提供了合理解释。最后提出强化学习视角下锻炼者-体育环境的互动模式, 试图从一个全新的角度探讨锻炼行为。     

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。     

儿童网络行为与学业成绩的关系:自我控制的调节效应

以547名4-6年级学生为研究对象,采用网络行为调查问卷、家庭富裕量表和青少年自我控制双系统量表,探讨儿童网络行为与学业成绩之间的关系,以及自我控制在二者之间的调节作用。结果发现:(1)儿童网络信息获取行为能够正向预测语文成绩;(2)自我控制调节网络信息获取行为与语文成绩之间的关系,同时也在儿童网络社交行为与语文成绩之间起调节作用。具体而言,自我控制中延迟满足的能力能够增强网络信息获取对语文成绩的促进作用,并且减缓网络社交行为对儿童的语文成绩的消极影响。     

反事实思维与内疚和羞耻的关系——以大学生和青少年罪犯为例

运用自我报告法从反事实思维的角度验证内疚与羞耻差异的"自我和行为"假设,探讨大学生和青少年罪犯在反事实思维与内疚和羞耻关系方面的特点。结果表明:1)研究结果不支持Lewis提出的内疚与羞耻差异的"自我和行为"假设,甚至与该假设相反;2)在真实的情境中,大学生和青少年罪犯内疚感和羞耻感与反事实思维的特点具有一致性。     

Impulse and Self-Control From a Dual-Systems Perspective

ABSTRACT— Though human beings embody a unique ability for planned behavior, they also often act impulsively. This insight may be important for the study of self-control situations in which people are torn between their long-term goals to restrain behavior and their immediate impulses that promise hedonic fulfillment. In the present article, we outline a dual-systems perspective of impulse and self-control and suggest a framework for the prediction of self-control outcomes. This framework combines three elements that, considered jointly, may enable a more precise prediction of self-control outcomes than they do when studied in isolation: impulsive precursors of behavior, reflective precursors, and situational or dispositional boundary conditions. The theoretical and practical utility of such an approach is demonstrated by drawing on recent evidence from several domains of self-control such as eating, drinking, and sexual behavior.     

A comparison of techniques to increase children's resistance to temptation

This study compared impulsive and reflective children in their ability to benefit from various self-control strategies. While verbal controlling responses were more effective than various non-verbal strategies for both groups, only children identified as impulsive with the MFF responded differentially to various self-controlling strategies. It was also found that age is correlated with both conceptual tempo and the effectiveness of efforts at modifying impulsivity.     

社会排斥与大学生冲动性消费行为：名人崇拜的中介及自我控制的调节作用

为探讨社会排斥与冲动性消费的关系及其作用机制,本研究采用社会排斥量表、名人崇拜量表、自我控制双系统量表以及冲动性购买倾向量表,对811名大学生进行调查。结果表明：（1）在控制性别、年龄、家庭月收入和每月生活费后,社会排斥显著正向预测冲动性消费;（2）名人崇拜在社会排斥和冲动性消费间起部分中介作用;（3）自我控制在中介路径的前半段及直接路径间起调节作用。本研究有助于对大学生冲动性消费的理解和干预。     

Reflective and Impulsive Determinants of Consumer Behavior

This article describes a dual‐system model of consumer behavior. This model is based on the assumption that all human behaviors are a joint function of reflective and impulsive mechanisms. Those mechanisms have different principles of operation but contribute to the act of buying. However, the relative contribution of impulsive and reflective processes depends on personal and contextual circumstances. The operation and interaction of the 2 systems at different stages of information processing is described and applied to the dynamics of consumer behavior, with a special emphasis on impulse buying.     

Approaches to the Empirical Study of Convenience Theory for White-Collar Crime

Convenience theory suggests that members of the elite in society commit financial crime in their professional roles when alternative actions require too much effort. Convenience is a relative concept where white-collar crime is chosen over legitimate actions when there is a strong economical motive, ample organizational opportunities, and acceptance of deviant behavior. To study convenience theory, four investigations are presented in this article: statistical sample of white-collar criminals, autobiographies by white-collar criminals, internal investigations of white-collar crime, and student elicitation on white-collar crime. The strongest relationship within convenience theory seems to be the effect from willingness to commit crime based on deviant behavior on organizational opportunity to commit white-collar crime.     

Self‐Regulatory Resources Power the Reflective System: Evidence From Five Domains

In this commentary, I focus on the deficiencies in the reflective‐impulsive model (RIM) by Strack, Werth, and Deutsch (2006) in terms of understanding the mechanics of the reflective system. Strack et al. outlined the cognitive architecture of the consumer with the RIM but failed to specify how its most impressive feature, the reflective system, is powered. Drawing on the literature on self‐regulation (as a reconceptualization of RIM incompatibility), I argue that self‐regulatory resources drive the reflective system. Research from 5 domains—overeating among dieters, impulsive spending, logical thinking, making choices, and subjective perceptions of duration—supports this hypothesis.     

Reason to Believe: Representations of Aggression as Phenomenological Read-Out

Men tend to view their own aggression as an instrumental act aimed at imposing control, whereas women tend to view theirs as an expressive act resulting from a loss of self-control. These interpretations have been called social representations based on their presumed social origins and mode of transmission. However, if women’s self-control is generally higher than men’s, they would be expected to behave aggressively only infrequently and at higher levels of provocation. Aggression would be experienced phenomenologically as a loss of self-control. In Study 1, a student sample, men scored higher than women on instrumental beliefs, impulsivity, and risk seeking. As predicted, instrumental beliefs were associated with higher impulsive risk seeking and an expressive representation was positively associated with temper. In Study 2, an offender sample, there were no gender differences in instrumental beliefs, physical aggression, temper, carelessness, and present orientation. Instrumental beliefs were again associated with impulsive risk seeking and, to a lesser extent, temper. Expressive beliefs were again associated with temper and, to a lesser extent, present orientation. Physical aggression was associated with holding instrumental beliefs, impulsive risk seeking, and temper. The model is broadly supported and directions for future work are suggested.     

Investigating the predictive validity of implicit and explicit measures of motivation on condom use,physical activity and healthy eating

The literature on health-related behaviours and motivation is replete with research involving explicit processes and their relations with intentions and behaviour. Recently, interest has been focused on the impact of implicit processes and measures on health-related behaviours. Dual-systems models have been proposed to provide a framework for understanding the effects of explicit or deliberative and implicit or impulsive processes on health behaviours. Informed by a dual-systems approach and self-determination theory, the aim of this study was to test the effects of implicit and explicit motivation on three health-related behaviours in a sample of undergraduate students (N?=?162). Implicit motives were hypothesised to predict behaviour independent of intentions while explicit motives would be mediated by intentions. Regression analyses indicated that implicit motivation predicted physical activity behaviour only. Across all behaviours, intention mediated the effects of explicit motivational variables from self-determination theory. This study provides limited support for dual-systems models and the role of implicit motivation in the prediction of health-related behaviour. Suggestions for future research into the role of implicit processes in motivation are outlined.
