Post-extinction conditional stimulus valence predicts reinstatement fear: Relevance for long-term outcomes of exposure therapy

Exposure therapy for anxiety disorders is translated from fear conditioning and extinction. While exposure therapy is effective in treating anxiety, fear sometimes returns after exposure. One pathway for return of fear is reinstatement: unsignaled unconditional stimuli following completion of extinction. The present study investigated the extent to which valence of the conditional stimulus (CS+) after extinction predicts return of CS+ fear after reinstatement. Participants (N = 84) engaged in a differential fear conditioning paradigm and were randomised to reinstatement or non-reinstatement. We hypothesised that more negative post-extinction CS+ valence would predict higher CS+ fear after reinstatement relative to non-reinstatement and relative to extinction retest. Results supported the hypotheses and suggest that strategies designed to decrease negative valence of the CS+ may reduce the return of fear via reinstatement following exposure therapy.     

Anxiety after remembering stressful academic versus brush with death events: The moderating roles of future time perspective and personal intimacy

This study examines: (i) whether recalling stressful autobiographical events results in anxiety, (ii) the relation of memory qualities to anxiety, and (iii) the relation of future time perspective and personal intimacy to experiencing anxiety. Participants (N = 120) completed Future Time Perspective, Personal Intimacy and State Anxiety scales. They were randomly assigned to recall a brush with death, a stressful academic deadline, or a no-stress control. Memory qualities (vividness and significance) were assessed. As expected, recalling stressful events resulted in anxiety with more personally significant events related to higher anxiety. Having a more open-ended future time perspective related to lower anxiety after recalling a stressful academic deadline, whereas greater personal intimacy predicted lower anxiety after recalling a brush with death. Findings are discussed in terms of factors that may serve to moderate the link between stressful memories and the experience of anxiety.     

Health-related behaviours and their correlates in a general population sample of 45-year old women

Abstract

Preventive strategies for menopausal women to reduce the risks for osteoporosis and cardiovascular disease has been the focus of considerable attention, but understanding of mid-aged women's behavioural risk factors for these diseases is meagre. The current study describes a range of health-related behaviours and their psychosocial correlates, in a sample of 45-year old women, recruited from five general practices and assessed by postal survey (N=106, response rate 60%). Results suggest that health promotion for this group might best focus upon increases in regular exercise, calcium intake and breast awareness, and decreases in cigarette and caffeine consumption. The behaviours assessed were generally not inter-related. However, several associations were identified between behaviours and health and psychosocial variables. The main ones were the association between menopausal status and smoking, and the relationship between body weight, self-esteem and physical exercise. It is argued that the menopause transition can be an opportunity for preventive work.     

从《太平经》看早期道教的孝道思想

孝道思想是道教的重要内容,其产生时间较早,并受到道教产生前背景观念的影响。道教早期文献《太平经》具有大量道教孝道思想的表达,并且具有代表性。本文通过对早期道教孝道思想产生的背景和对《太平经》文本的分析,得出道教早期孝道思想两重意蕴,即世俗层面和神圣层面,并指出道教孝道思想的最终落脚点在效法天地、顺其自然。     

Lay theory of race affects and moderates Asian Americans' responses toward American culture

People may hold different understandings of race that might affect how they respond to the culture of groups deemed to be racially distinct. The present research tests how this process is moderated by the minority individual's lay theory of race. An essentialist lay theory of race (i.e., that race reflects deep-seated, inalterable essence and is indicative of traits and ability) would orient racial minorities to rigidly adhere to their ethnic culture, whereas a social constructionist lay theory of race (i.e., that race is socially constructed, malleable, and arbitrary) would orient racial minorities to identify and cognitively assimilate toward the majority culture. To test these predictions, the authors conducted 4 studies with Asian American participants. The first 2 studies examine the effect of one's lay theory of race on perceived racial differences and identification with American culture. The last 2 studies tested the moderating effect of lay theory of race on identification and assimilation toward the majority American culture after this culture had been primed. The results generally supported the prediction that the social constructionist theory was associated with more perceived similarity between Asians and Americans and more consistent identification and assimilation toward American culture, compared with the essentialist theory.     

Moderating effects of three coping strategies and self-esteem on perceived discrimination and depressive symptoms: A minority stress model for Asian international students

This study examined 3 coping strategies (reflective, suppressive, and reactive), along with self-esteem, as moderators of the relation between perceived discrimination and depressive symptoms. International students (N = 354) from China, India, Korea, Taiwan, and Hong Kong provided data via an online survey. The role of perceived general stress was statistically controlled. Hierarchical regression analyses indicated a significant direct effect of perceived discrimination, a significant 2-way interaction of perceived discrimination and suppressive coping, and a significant 3-way interaction of perceived discrimination, reactive coping, and self-esteem in predicting depressive symptoms. An increased tendency to use suppressive coping appeared to strengthen the association between perceived discrimination and depressive symptoms. In contrast, the association between perceived discrimination and depressive symptoms was not significant when reactive coping was infrequently used, but only for students with relatively high self-esteem.

自我觉知的适应、不适应性及其在心理疗法中的作用

自我觉知是当注意力指向个体自身时对自己所产生的内部主观状态,根据其指向及程度可以有多种分类方法。自我觉知在心理过程中既有适应性,如促进自我了解、对他人的理解、提高自尊等;但过度的自我觉知会对心理产生不良影响,诸多研究对其与抑郁和焦虑的关系进行了论证。很多心理疗法中都涉及到自我觉知对心理状况的影响,包括格式塔疗法、来访者中心疗法、森田疗法等等。如何保持适度的自我觉知以促进心理健康是需要进一步研究的。     

大学生作弊:是道德自我欺骗吗?

以往关于考试作弊的研究大都着眼于相关因素,还很缺乏对主体意识结构的分析。本研究以自我欺骗为理论框架,以大学生为被试,通过一个行为实验及与实验有关问题的分析,从意识与潜意识两个层面对大学生的作弊行为进行了探究。结果表明研究样本的31.63%的大学生的作弊属于道德自我欺骗,即作弊时意识与潜意识持有一个相互矛盾的错误信念,具体说就是,在意识里并没有意识到作弊是不道德的,但同时在潜意识里却认为它是不道德的。     

记忆编码中目标与背景的情绪一致性对记忆提取的影响

摘 要 本研究将经典情绪启动范式和学习-再认范式相结合,探讨学习时启动与目标的情绪一致性对目标再认的影响。在记忆编码阶段,以情绪面孔图片为启动刺激、一般情绪图片为目标刺激,要求被试对目标图片的效价进行判断;在提取阶段向被试呈现一般情绪图片,要求被试判断是否在前一阶段见过。结果表明,编码阶段的加工背景对记忆提取产生了显著影响。一致启动促进了认知加工与记忆编码,提高了再认正确率。ERP结果也表明,在目标刺激呈现后300-500ms,编码时的情绪一致性对再认阶段消极目标诱发的ERP产生了显著影响。     

Perceived similarity, proactive adjustment, and organizational socialization

The present study explores how perceived demographic and attitudinal similarity can influence proactive behavior among organizational newcomers. We propose that newcomers who perceive themselves as similar to their co-workers will be more willing to seek new information or build relationships, which in turn will lead to better long-term adjustment. Results from a three-wave field investigation of newcomer proactive behavior show that newcomer perceptions of surface-level similarity to the rest of the work group in education and gender increased proactive adjustment behavior. Contrary to our expectations, perceived similarity in terms of age decreased proactive adjustment behavior—in other words, newcomers who were significantly different from their co-workers in age engaged in more proactive adjustment behaviors. Deep-level similarity in terms of work style was associated with higher levels of role clarity, but this relationship was not mediated by proactive adjustment behavior.
