Challenges in the conceptualization of trait self-control as a psychological construct

Self-control is widely believed to be a valuable characteristic that contributes to leading a healthy, happy, and successful life through the effective pursuit of long-term goals. Yet, despite a prolific literature spanning decades, essential questions about the conceptual nature of trait self-control remain unanswered. Substantially different perspectives on the theoretical nature of (trait) self-control coexist side by side. We briefly review prominent views informing what trait self-control as a psychological construct is. On this basis, we identify four conceptual challenges that we think the field should address moving forward: (a) integrating theoretical notions, (b) addressing variability in individual goals, (c) acknowledging variability in dominant responses, and (d) anchoring trait self-control in a nomological network. We highlight why addressing these challenges is crucial for gaining a deeper understanding of trait self-control. We also suggest how theoretical conceptualizations of trait self-control might do so and the implications this would bear for measurement and interventions.     

A Network Analysis Approach on the Psychological Flexibility/Inflexibility Model

Acceptance and Commitment Therapy (ACT) is purported to work via targeting six interrelated processes summarized as the Psychological Inflexibility/Psychological Flexibility (PI/PF) model. However, the theoretical structure and interconnections of this model have not been sufficiently explored. Lacking are examinations of the interrelations among its components. Network Analysis (NA) can model PI/PF as a system of interconnected variables. We aimed at exploring the role and associations of the PI/PF model’s components using NA in two different samples and sets of scales, and compare its structure across sub-samples. Sample 1 consisted of 501 individuals, who completed an online battery of questionnaires including the Multidimensional Psychological Flexibility Inventory, and Sample 2 consisted of 428 people, who completed an online set of six ACT measures, each assessing a component of the PI/PF model. NA could not verify the six ACT dimensions as distinct components. Values and Committed Action components were found to be strongly associated and combined in a group in both sets of measures and samples. Interestingly, Acceptance and Defusion were not the most central components as purported in some ACT conceptualizations, whereas Self-as-Context had a key role on both sets of measures and its items were often merged with Present Moment Awareness items. No significant differences were found in the comparison of networks across different subsamples and sets of scales. After combining different sets of scales, the six ACT components could not be completely verified as distinct entities, which might reflect problems with the theoretical model, or with the scales used. All components had critical roles in the model, particularly Self-as-Context, which reflects the need to redirect research towards this understudied construct. Findings point towards considerations of a triflex instead of a hexaflex ACT model.     

内群体情绪强度的系统动力学模型

选取自愿参加本实验的某高校20个教学班级的686人为被试,基于社会网络（social network）的系统动力学（system of dynamic）建模的方法建立了内群体情绪强度的系统动力学模型,并采用心理实验的方法对模型的合理性进行了检验,结果表明,所建立的模型能够与实验数据较好拟合,能较合理地对内群体情绪强度变化的动力学规律进行刻画。此外,通过与以往同类研究对比,本研究还发现：内群体情绪强度的减弱滞后于群体内群体情绪传播的减弱。     

驾驶员视觉注意对危险识别的影响及作用机制

驾驶中, 有效的视觉注意模式是驾驶员搜索与识别潜在道路危险的先决条件。通过分析驾驶员视觉注意对危险识别的影响, 提出情境意识假设与心理负荷假设。情境意识假设认为, 情境意识的质量决定了驾驶员视觉注意模式的灵活性, 进而影响危险识别。心理负荷假设认为, 心理负荷水平提高, 驾驶员视觉注意趋于集中, 不利于危险识别。建议未来研究可以在比较不同驾驶员情境意识的认知兼容性, 应用汽车驾驶自动化技术降低心理负荷以及检测并区分情境意识与心理负荷的影响等方面加以深入。     

飞行员情境认知的模糊综合评判

借用环境科学中环境质量评价的概念和方法,建立了飞行员情境认知的多级模糊综合评判模型,并用该模型对飞行员的情境认知进行了综合评判。研究表明,用模糊综合评判方法评价飞行员的情境认知可以提供真实、全面的飞行认知信息,为飞行员的训练有效性及安全性提供可靠依据。     

网络医疗发展带来的法律问题

随着网络技术迅速发展,网络医疗以其方便快捷,患者足不出门便可得到一流的医院、最优秀的医生、最先进的医疗服务等,这些深受患者青睐。网络医疗对医学发展将起到不可低估的作用。然而网络医疗在其发展的同时,也存在一些不可忽视的问题。网络医疗在改变传统医患关系模式的同时也带来了一系列诸如保障患者隐私权、保护知识产权、法律关系改变等新的法律问题。这些问题不解决,对网络医疗健康发展,对医患合法权利保护等都会带来不利影响,针对这一系列问题展开论述,提出解决问题的办法。     

普通高等医学院校人文医学教育的现状与思考

人文医学教育是高等医学教育的重要组成部分,也是医学发展、医学人才培养的内在要求。普通高等医学院校在这项工作中存在着不足,如课程体系不完善、课程结构不合理、人文气氛短缺等。因此,有必要采取一些措施予以完善,从而跟上国家高等医学教育改革的步伐,促进医学教育的进一步完善。     

儿童欺骗的情境依赖

采用竞争游戏的方式研究3～6岁儿童在外显和隐蔽情境里的欺骗。结果表明4、5岁儿童行为上的隐蔽欺骗和错误信念理解显著相关;3岁儿童语言上的外显欺骗（说谎）和错误信念理解显著相关;各年龄段儿童行为上的外显欺骗和错误信念理解没有显著相关。和Cartson（1998）的研究结果不一致的是,本研究中4、5、6岁儿童的隐蔽欺骗人数显著超过外显欺骗人数。结果提示,语言上的外显欺骗（说谎）不仅和儿童的执行功能有关,还可能和欺骗时的情境压力有关。     

The Big Five personality traits,Big Two metatraits and social media: A meta-analysis

This article reported a meta-analysis of the relationships between social network site use and the Big Five (neuroticism, extraversion, openness, agreeableness, and conscientiousness) as well as the Big Two (plasticity and stability) personality meta-traits. A random effect meta-analysis model was used to calculate the meta-results of Big Five. Extraversion and openness were the strongest predictor of SNS activities (e.g. gaming, SNS interaction, etc.), while conscientiousness, neuroticism, and agreeableness only correlated with a few of the SNS activities. A meta-analytical structural equation model further demonstrated that plasticity was positively correlated with SNS activities, whereas stability was a negative predictor. Practical implications for social media industry and users were discussed.     

Situation selection across adulthood: the role of arousal

In this study, we investigated age differences in situation selection to understand the role stimulus arousal plays in motivating age differences in this type of emotion regulation. Participants freely selected from a set of affective videos using information about the valence and arousal of each stimulus. There were age differences both in the valence and arousal of selected stimuli. Older adults selected more neutral and low-arousal stimuli while younger adults selected more negative and high-arousal stimuli. We consider these results in light of recent theoretical models and conclude that studies of age differences in emotion regulation must consider both valence and arousal.
