French Validation of the Competitive Aggressiveness and Anger Scale (FVCAAS)

The aim of this study was to propose a French Validation of the Competitive Aggressiveness and Anger Scale (FVCAAS). The instrument was developed from the original version, which is composed of two subscales (six items by subscales) assessing aggressiveness and anger in competitive athletes (CAAS, Maxwell & Moores, 2007). Four studies have been conducted with 1428 competitors. In the first study, the exploratory factor analysis extracted the two-factor structure from the original version, both with good internal consistency. The second study confirmed that the two-factor structure of the instrument was consistent with the original version and showed its partial invariance across genders. The third study demonstrated the temporal stability of the FVCAAS. In the fourth study, both concurrent and discriminant validities were confirmed, supporting the validity and reliability of the FVCAAS. The contributions of this study and limitations are discussed, together with perspectives for future studies of aggressiveness in competitive sports.     

Can imagined intergroup contact change (internal) dialogues on differences between ingroup and outgroup?

Several positive functions have been ascribed to integrative internal dialogues (IDs), which are based on mutual openness to a partner's viewpoint and a readiness to consider his/her arguments in order to potentially modify one's own stance. As the technique of imagined intergroup contact (IIC) favorably influences attitudes towards outgroup members, it was hypothesized that IIC would have a beneficial impact on IDs with an outgroup member when the dialogue is focused on differences between ingroup and outgroup. In the experiment, 151 people (80 women) participated. It revealed that after IIC, both the dialogue author's confrontational attitude and the interlocutor's integrative attitude decreased. Thus, IIC made participants less inclined to gain an advantage over their imagined outgroup interlocutors and more inclined to give them freedom in IDs. However, the effect was significant only when the author's involvement in ID was high or medium.     

The Multilevel Relationships of HIV‐Related Stigma to Child and Caregiver Mental Health among HIV‐Affected Households in South Africa

HIV/AIDS‐related (HAR) stigma is still a prevalent problem in Sub‐Saharan Africa, and has been found to be related to mental health of HIV‐positive individuals. However, no studies in the Sub‐Saharan African context have yet examined the relationship between HAR stigma and mental health among HIV‐negative, HIV‐affected adults and families; nor have any studies in this context yet examined stigma as an ecological construct predicting mental health outcomes through supra‐individual (setting level) and individual levels of influence. Multilevel modeling was used to examine multilevel, ecological relationships between HAR stigma and mental health among child and caregiver pairs from a systematic, community‐representative sample of 508 HIV‐affected households nested within 24 communities in KwaZulu‐Natal, South Africa. Two distinct dimensions of HAR stigma were measured: individual stigmatizing attitudes, and perceptions of community normative stigma. Findings suggest that individual‐level HAR stigma significantly predicts individual mental health (depression and anxiety) among HIV‐affected adults; and that community‐level HAR stigma significantly predicts both individual‐level mental health outcomes (anxiety) among HIV‐affected adults, and mental health outcomes (PTSD and externalizing behavior scores) among HIV‐affected children. Differentiated patterns of relationships were found using the two different stigma measures. These findings of unique relationships identified when utilizing two conceptually distinct stigma measures, at two levels of analysis (individual and community) suggest that HAR stigma in this context should be conceptualized as a multilevel, multidimensional construct. These findings have important implications both for mental health interventions and for interventions to reduce HAR stigma in this context.     

第三方惩罚的神经机制：来自经颅直流电刺激的证据

第三方惩罚既是社会规范在群体得以维系的基石, 也是个体维护社会规范的体现。当前关注社会规范的神经研究大多基于第二方惩罚的独裁者或最后通牒实验框架, 缺乏对第三方维护社会规范过程中相关脑区活动的探索, 对这一过程的内在神经机制也不清楚。本文基于第三方惩罚的独裁者博弈框架, 对右侧背外侧前额叶区域(DLPFC)进行不同极性的经颅直流电刺激(tDCS), 同时依据第三方是否需要为其惩罚付出成本设计了零成本和有成本两个实验任务。结果发现, 第三方在零成本任务的情绪反应和惩罚显著受到tDCS设置的影响, 且阴极刺激显著提升了第三方的惩罚值, 这表明情绪机制对第三方惩罚有着重要影响。另外, 第三方在零成本和有成本任务中的惩罚差异在不同tDCS设置之间也存在显著差异, 这与第三方惩罚还受到自利机制影响的观点相符。本文率先为右侧DLPFC活动影响第三方惩罚提供了神经层面的证据, 且支持了第三方对社会规范的遵从与其负性情绪反应和自利加工密切相关的机制解释。     

班级欺凌规范与欺凌行为：群体害怕与同辈压力的中介作用

本文通过两个研究探讨了群体因素中的班级欺凌规范如何通过同辈压力、群体害怕影响欺凌行为的发生。研究1为实验研究, 被试为186名小学高年级学生(M_age = 11.36 ± 0.99岁)。结果表明在不同情境(欺凌/非欺凌)的启动下, 各变量得分均具有显著差异; 进一步分析仅发现同辈压力的中介作用边缘显著。研究2为相关研究, 943名小学高年级及初二学生(M_age = 12.00 ± 1.32岁)填写班级欺凌规范、同辈压力和欺凌行为问卷。HLM分析显示同辈压力在班级欺凌规范与欺凌行为起显著中介作用。     

Postural control after unexpected external perturbation: Effects of Parkinson’s disease subtype

Different clinical subtypes of Parkinson’s disease (PD) have long been recognized. Recent studies have focused on two PD subtypes: Postural Instability and Gait Difficulty (PIGD) and Tremor Dominant (TD). PIGD patients have greater difficulties in postural control in relation to TD. However, knowledge about the differences in reactive adjustment mechanisms following a perturbation in TD and PIGD is limited. This study aimed to compare reactive postural adjustments under unexpected external perturbation in TD, PIGD, and control group (CG) subjects. Forty-five individuals (15 TD, 15 PIGD, and 15 CG) participated in this study. Postural perturbation was applied by the posterior displacement of the support surface in an unexpected condition. The velocity (15 cm/s) and displacement (5 cm/s) of perturbation were the same for all participants. Center of pressure (CoP) and center of mass (CoM) were analyzed for two reactive windows after the perturbation (0–200 ms and 200–700 ms). The Bonferroni post hoc test indicated a higher range of CoP in the PIGD when compared to the CG (p = 0.021). The PIGD demonstrated greater time to recover the stable posture compared to the TD (p = 0.017) and CG (p = 0.003). Furthermore, the TD showed higher AP-acceleration peak of CoM when compared to the PIGD (p = 0.048) and CG (p = 0.013), and greater AP-acceleration range of CoM in relation to the CG (p = 0.022). These findings suggest that PD patients present worse reactive postural control after perturbation compared to healthy older individuals. CoP and CoM parameters are sensitive to understand and detect the differences in reactive postural mechanisms in PD subtypes.     

Methodological Challenges in the Study of Emotions in Politics and How to Deal With Them

This introductory article to the special issue zooms in on the literature on political emotions with a specific focus on methodological questions of “how to study” political emotions. To the extent that methodological matters are addressed in the extant literature, the associated challenges are often portrayed as a clash between social science and natural science disciplines, a clash frequently illustrated by the meeting between political science and neuroscience. Rather than being a clash between academic disciplines, this article argues that many of the methodological challenges facing emotional research have their origin in scholars' diverse views on the relationship between themselves as researchers and political emotions as a research object. In the light of this acknowledgment, the article encircles and discusses the methodological challenges associated with three key conceptual distinctions between: (1) individual and collective emotions, (2) emotions and reason, and between (3) involuntary political emotions and the strategic usage of political emotions. Using the contributions to this special issue as illustrations, the article argues in favor of moving beyond mutually exclusive dichotomies regarding these conceptual distinctions and offers pathways for dealing with current methodological challenges to emotional research. It points to methodological pluralism, transparency, and context‐sensitive research strategies.     

The effect of decision timing on the willingness to costly reward cooperation and punish noncooperation: Sanctioning the past,the present,or the future

Numerous studies have demonstrated that sanctions can promote cooperation. However, it is important to know not only that sanctions can work but also under what conditions people are actually willing to sanction cooperation positively (i.e., reward) or noncooperation negatively (i.e., punish). In this article, we demonstrate that people use sanctions less often and sanction more mildly when they decide about sanctioning before (instead of after) the occurrence of others' (non)cooperation (Experiments 1 and 2), regardless of whether they decide directly afterwards or after a time delay (Experiment 2). Moreover, we reveal that beforehand (as compared with afterwards) people have not yet formed clear sanctioning preferences (Experiment 3). These findings corroborate our reasoning that the decision environment beforehand induces nonconsequential reasoning and thereby hampers people's willingness to sanction. We discuss the theoretical, methodological, and practical implications of our work.     

Positive and negative affect and well-being in cardiac patients and their spouses: the mediating role of illness representations

Objective: The aim of this study was to examine whether illness representations of control and consequences mediate the relation of cardiac patients’ affect to well-being. A further aim was to examine this indirect relationship at a dyadic level (i.e. patient and spouse). Design and main outcome measures: One hundred and four patients with a cardiovascular disease and their spouses participated in the study. Positive and negative affect was assessed at baseline; illness representations were assessed 2 months later, and physical and psychological well-being 4 months later. Results: Illness representations generally mediated the impact of patients’ and spouses’ affect on well-being, while several actor and partner effects were found. However, it was only positive affect that was indirectly related to well-being, while the representations of personal and treatment control chiefly acted as mediators. The effects were stronger for patients than spouses, as well as for physical well-being. Conclusion: The results underline the strong connection between illness-related self-regulation and the overall person/environment interaction as depicted by affect. They also indicate the need to integrate theories on adaptation to illness, with models describing adaptation of couples to stressful conditions, and specific theories about the role of emotion in adaptation to illness.
