如何唤起和缓解重大损失情绪—— 来自行为和脑成像的证据

本研究在没有真实伤害的情况下研究重大损失情绪及相应的脑机制。通过一系列行为和脑成像实验, 研究者们摸索出了可靠诱发重大损失情绪的范式, 并从对比效应和金钱补偿角度初步探讨了缓解这种情绪的方法。研究发现, 由于自我防御机制的存在, 抑制了被迫接受条件下重大损失情绪的唤起, 但却成功唤起了被迫选择条件下重大损失的情绪。此外, 研究还发现, 金钱补偿和对比效应都是缓解重大损失情绪的有效策略。本研究不仅有利于认识重大损失情绪的信息加工机制, 而且也为涉及重大损失情绪的心理咨询和保险理赔制度等提供了行为和脑成像证据。     

赢者诅咒：心理机制、影响因素及应对策略

赢者诅咒是指在拍卖情境中, 竞价者为了获得拍卖品会过高估计其价值, 竞价成功以后当他发现其价值和自己之前的期望不一致时所产生的一种“诅咒”心理。赢者诅咒现象普遍存在于企业的资产拍卖、兼并重组、博彩游戏、投资决策等领域。损失规避和过度自信理论是赢者诅咒的主要心理机制, 而其影响因素主要有竞拍商品价值的不确定性、竞价人数、信息因素和竞价经验等。赢者诅咒的应对策略主要包括联合竞标、信息共享和学习。未来对赢者诅咒的研究需要进一步探讨赢者诅咒的心理机制、研究范式及本土化等问题。     

The roles of autonomous motivation and self-control lapses in concurrent adherence to a gluten-free diet and a self-chosen weight loss plan in adults with coeliac disease

Objective: Examine the correspondence between autonomous motivation, self-control lapses, and adherence, to a gluten-free diet (GFD) and weight loss plan in adults with coeliac disease; and assess the impact of the interaction of motivation style and self-control lapses on adherence to both diets.

Design: Cross-sectional survey in 519 adults with coeliac disease, 238 of whom were also attempting weight loss.

Main outcome measures: Adherence, motivation style, frequency of temptation and self-control lapses (e.g. when tired, stressed, happy) for GFD and weight loss plan.

Results: Autonomous motivation was higher, and amotivation lower, for the GFD than weight loss; adherence to the two diets was unrelated. Similar circumstances led to temptation and self-control lapses across diets; both were less frequent for the GFD than weight loss. Motivation and self-control lapses explained 21% and 35% of the variance in adherence, respectively; the interaction between motivation and lapse frequency did not explain additional variance for either diet.

Conclusions: There are clear benefits to developing autonomous motivations and strategies to resist temptation for both the GFD and weight loss. Understanding how these processes differ and interact across diets may lead to the design of interventions to improve adherence and weight outcomes in coeliac disease.     

Development and initial validation of the job loss grief scale

Background: Research on complicated grief (CG) symptoms following job loss is surprisingly rare. Involuntary job loss can turn someone’s world upside down and can result in loss of identity, social contacts, and self-worth. In this study, we drew on the literature on major life events in conceptualizing involuntary job loss as a significant and potentially devastating life event.

Objectives: The aim of this study was to develop and evaluate an instrument that measures job loss-related CG symptoms, the Job Loss Grief Scale (JLGS). The purpose of the JLGS is to foster systematic research on CG symptoms following job loss.

Design: A cross-sectional study

Methods: We recruited Dutch workers who had lost their job, 130 men and 158 women with an average age of 49.6 years. To examine the psychometric properties of the JLGS and its associations with other concepts we conducted correlational and confirmatory factor analyses.

Results: CFA revealed that the JLGS was a one-dimensional instrument, and that CG symptoms were distinguishable from depression and anxiety symptoms.

Conclusion: The JLGS is a reliable and valid instrument to measure job loss-related CG symptoms. The availability of the JLGS could stimulate systematic research on the antecedents and consequences of involuntary job loss.     

Mentalizing in Parents after Traumatic Loss. Analysis of Couple Counseling

Abstract

The aim of the study is to explore whether bereaved parents’ capacity to mentalize is related to their progression through grieving and how it changes during couple therapy. The clients’ RF levels were assessed using the Reflective Functioning Scale and Psychotherapy Reflective Functioning Scale Manual. The content of the sessions was analyzed using Thematic Analysis. At the beginning of the therapy, concrete images of the child’s death were more frequent and the parents’ RF was lower than their general RF level. As the therapy progressed these images were gradually supplanted by more mental references to the deceased child.     

Age-related hearing loss associated with altered response efficiency and variability on a visual sustained attention task

ABSTRACT

This study investigated the association between age-related hearing loss (ARHL) and differences in response efficiency and variability on a sustained attention task. The study population comprised 32 participants in a hearing loss group (HLG) and 34 controls without hearing loss (CG). Mean reaction time (RT) and accuracy were recorded to assess response efficiency. RT variability was decomposed to examine temporal aspects of variability associated with neural arousal and top-down executive control of vigilant attention. The HLG had a significantly longer mean RT, possibly reflecting a strategic approach to maintain accuracy. The HLG also demonstrated altered variability (indicative of greater decline in neural arousal) but maintained executive control that was significantly predictive of poorer response efficiency. Adults with ARHL may rely on higher-order attention networks to compensate for decline in both peripheral sensory function and in subcortical arousal systems which mediate lower-order automatic neurocognitive processes.     

Spatio-temporal accident analysis for accident prevention in relation to behavioral factors in driving: The case of South Anatolian Motorway

Analyzing the pattern of traffic accidents on road segments can highlight the hazardous locations where the accidents occur frequently and help to determine problematic parts of the roads. The objective of this paper is to utilize accident hotspots to analyze the effect of different measures on the behavioral factors in driving. Every change in the road and its environment affects the choices of the driver and therefore the safety of the road itself. A spatio-temporal analysis of hotspots therefore can highlight the road segments where measures had positive or negative effects on the behavioral factors in driving. In this paper 2175 accidents resulted in injury or death on the South Anatolian Motorway in Turkey for the years between 2006 and 2009 are considered. The network-based kernel density estimation is used as the hotspot detection method and the K-function and the nearest neighbor distance methods are taken into account to check the significance of the hotspots. A chi-square test is performed to find out whether temporal changes on hotspots are significant or not. A comparison of characteristics related driver attributes like age, experience, etc. for accidents in hotspots vs. accidents outside of hotspots is performed to see if the temporal change of hotspots is caused by structural changes on the road. For a better understanding of the effects on the driver characteristics, the accidents are analyzed in five groups based on three different grouping schemes. In the first grouping approach, all accident data are considered. Then the accident data is grouped according to direction of the traffic flow. Lastly, the accident data is classified in terms of the vehicle type. The resultant spatial and temporal changes in the accident patterns are evaluated and changes on the road structure related to behavioral factors in driving are suggested.     

A nuanced look into youth journeys of gender transition and detransition

Some media have suggested that many youths who have previously completed a gender transition are “detransitioning”. Their experience is often framed around the idea of regrets but rare are the articles that provide a nuanced examination of their journey. This article presents the perspectives of youths who have detransitioned or discontinued a transition regarding their experiences and feelings on their journey from transition to detransition. Semi-structured interviews were conducted with 20 youths between the age of 16 and 25 years who were recruited on social media and who transitioned and detransitioned or discontinued their transition. Data were analysed according to thematic analysis. Regrets and feelings of satisfaction can both coexist. The processes of transition and discontinuation or detransition appear to be non-linear and participants do not necessarily return to a cisgender identity. Ambiguous loss theory is applied to frame youth experiences and feelings and to suggest way forward for intervention.

Highlights

• This paper examines the experiences and feelings of youth on their journey from transition to detransition.
• Their journey is experienced as non-linear, and often comprised mixed feelings and experiences about transition and detransition steps.
• Ambiguous loss theory allows a nuanced understanding of feelings and experiences of their journey from transition to detransition.
