How does mindfulness modulate daily stress response: evidences from ambulatory assessment

Objective: Mindfulness has been found to be associated with less adverse stress response. However, little is known about how mindfulness modulates stress response in the real daily life. The current study investigated the relation between daily stress and negative emotions, and explored a mediational link via perceived loss of control, and moderation by dispositional mindfulness, to better understand this association. Design: A total of 95 college students were recruited to complete a questionnaire and to report on their stress, perceived loss of control and negative emotions in daily life. Main Outcome Measures: Mindful Attention Awareness Scale (MAAS) was used to assess dispositional mindfulness. Stress, perceived loss of control and negative emotions were assessed by ambulatory assessment. Results: Stress was positively related with negative emotions at within-person level. Perceived loss of control mediated the relationship between stress and negative emotions. Furthermore, participants with higher levels of dispositional mindfulness showed an attenuated association between stress and anger, and also attenuated associations between perceived loss of control, and anger and fatigue at within-person level. Conclusion: These findings point to perceived loss of control as an important key factor in daily stress effects. Dispositional mindfulness appears to have beneficial effects in that it attenuates the impact of daily stressors on individuals’ wellbeing. Clinical implications and limitations are discussed.     

Extreme malleability of preferences: Absolute preference sign changes under uncertainty

Malleability of preferences is a central tenet of behavioral decision theory. How malleable preferences really are, however, is a topic of debate. Do preference reversals imply preference construction? We argue that to claim preferences are construed, a demonstration of more extreme preference malleability than simple preference reversals is required: absolute preference sign changes within participants. If respondents value a prospect positively in 1 condition but negatively in a different condition, preferences cannot be considered stable. Such absolute preference sign changes are possible under uncertainty. In 2 incentive‐compatible experiments, we found participants were willing to pay to take part in a gamble and also demanded to be compensated to take part in a subsequent gamble with identical outcomes and probabilities. Such absolute preference sign changes within participants led to simultaneous risk aversion and risk seeking for the same risky prospect, suggesting that, at least in the domain of risky decisions, consumers' preferences are indeed malleable and construed.     

Hormonal changes after competition predict sex‐differentiated decision‐making

Recent neuroendocrinology research has pointed out that testosterone (T) and cortisol (C) changes after social interactions can predict risk‐taking behavior in decision‐making, depending on the sex of participants. However, previous research has focused on the effects of the changes in only one hormone, rather than the interaction between them, even though C can suppress T activity. Our aim was to test, in men and women, the role of T changes moderated by C changes after competition in decision‐making. Thus, 48 males and 46 females completed the Iowa Gambling Task (IGT) after a laboratory competition or a noncompetitive task (control task). Saliva samples were collected before and after the competition/control task. IGT was employed to measure risk‐taking decision‐making, considering the degree of uncertainty. Our results showed sex‐differentiated effects of T and C changes on risk‐taking behavior. On the one hand, men from both task groups (Competition/Control) who had higher C and T changes after competition showed more risk‐taking decision‐making (higher IG Risk). On the other hand, women from the competitive task who had high C and T showed conservative decision‐making. Therefore, these results show sex‐differentiated decision‐making profiles, which would help to understand how men and women behave after experiencing a competitive social context.     

When does procedural justice influence perceived legitimacy? The role of standing uncertainty and group identification

Many empirical studies have shown that procedural justice is the key determinant of whether an individual perceives an authority figure as legitimate. However, based on relational models of procedural justice and the uncertainty management model, there is reason to believe that the association between procedural justice and perceived legitimacy may be stronger for individuals who are uncertain about their standing as group members (moderation); this interaction might predict group identification and, in turn, perceived legitimacy (mediation). We tested this mediated moderation model in two experiments (Studies 1a and 1b) and a field study (Study 2) using different operationalizations of standing uncertainty across studies. The results of Studies 1a and 1b demonstrated that the association between procedural justice and perceived legitimacy was stronger for participants with high (vs. low) standing uncertainty. Study 2 showed that group identification mediated the association between this interaction effect and perceived legitimacy. Together, the results of the mediated moderation analysis showed that procedural justice was positively associated with perceived legitimacy through high group identification when standing uncertainty was high. The theoretical contributions and practical implications of our findings are discussed.     

Aggression and risk‐taking as adaptive implementations of fast life history strategy

Within the evolutionary life history (LH) framework, aggression and risk‐taking are adaptive implementations of a fast LH strategy to adapt to environmental unsafety and unpredictability. Based on a longitudinal sample of 198 Chinese adolescents living in rural areas, half of whom were separated from their parents, this study tested LH hypotheses about aggression and risk‐taking in relation to safety constraints in the childhood living environments. The results showed that proxies of environmental unpredictability, including parental separation, were positively associated with aggression and risk‐taking and negatively associated with slow LH strategy, which in turn was negatively associated with aggression and risk‐taking. Children separated from their parents scored lower on slow LH strategies and higher on aggression and risk‐taking. These findings support the evolutionary assumption that human development responds to safety cues through behavioral implementations of LH strategies.     

Engagement envers le supérieur et recherche de feedback négatif : le rôle des variables de statut du supérieur

The relationship between employees’ affective commitment to the supervisor and negative feedback seeking is barely explored in the literature. Moreover, the role of the characteristics related to the context where this relationship develops is unknown. In the present article, we examine the relationship between affective commitment to the supervisor and negative feedback seeking using data collected from 250 employees affiliated with organizations operating in the service industry. Three moderating variables were measured: supervisor-organization value incongruence, supervisors’ networking ability, and supervisors’ perceived organizational status. Data analysis through moderated multiple regression indicates that commitment to the supervisor is positively related to negative feedback seeking, and that this relationship is enhanced when the supervisor is perceived to have a low value incongruence with the organization or a weak networking ability. In contrast, supervisors’ perceived organizational status did not exert a moderating role. We discuss the implications of these findings for research on feedback seeking behavior in the workplace.     

谁更愿意购买绿色产品？认识绿色消费者

绿色消费虽然备受关注但消费者积极性却不高,这可能和个体差异性有关。为了考察绿色消费的积极性,本研究从个体差异的视角出发,引入购买时间距离这一变量,以揭示面对绿色产品的矛盾性消费者究竟更愿现在购买还是将来,决策模式是否会存在个体差异。研究发现,时间距离调节绿色消费观与产品购买意愿的关系,而产品价值感知部分中介了该调节作用。具体来说,绿色消费者不会受到时间框定的影响,而非绿色消费者则表现出时间框定效应即更倾向于在将来而不是现在购买绿色产品;这是因为绿色消费观以自上而下的方式影响绿色消费者动机加工,使绿色产品的价值感知较为稳定,而非绿色消费者的价值感知则根据购买时间距离的不同而变化。研究结果说明在生态文明建设日益紧迫的当下培育个体绿色消费观具有重要的意义。
