Infertility-Related Stress and Life Satisfaction among Chinese Infertile Women: A Moderated Mediation Model of Marital Satisfaction and Resilience

The present study investigated the effects of infertility on Chinese women’s life satisfaction. Infertile women (n?=?466) who were seeking medical help completed a survey that included the Fertility Problem Inventory (FPI), the Dyadic Adjustment Questionnaire (DAS), the Connor-Davidson Resilience Scale (CD-RISC), the Satisfaction with Life Scale, and demographic variables. We used a moderated mediation model to test our hypotheses, with life satisfaction as the dependent variable, representations about the importance of parenthood as the independent variable, the impact of infertility on life domains as a mediator, and marital satisfaction and resilience as moderators. Results showed that representations about the importance of parenthood and the impact of infertility on life domains are two main types of infertility-related stress, which could play independent roles in predicting life satisfaction. Representations about the importance of parenthood had a negative indirect effect on life satisfaction through the impact of infertility on life domains, and the indirect effect of the impact of infertility on life domains was moderated by marital satisfaction and resilience. Specially, representations about the importance of parenthood had a weaker indirect effect (through the impact of infertility on life domains) on life satisfaction in individuals with higher marital satisfaction or resilience. Therefore, the type of infertility-related stress and both marital satisfaction and resilience should be addressed in psychological interventions for women coping with infertility in mainland China.

全球化语境下的多元文化能力模型及其在跨文化合作中的应用

全球化带来了丰富的多元文化经验, 开阔了人们视野的同时, 也造成了认知负担, 进而可能引发对外文化群体的抵触情绪和排斥行为。多元文化经验的普遍性和两面性突显了对其进行合理管理和灵活应用的重要性。然而, 现有的文化能力的理论大多在全球化研究早期提出, 已经无法应对全球化带来的新变化。在文化会聚主义理论框架下, 将文化视为动态发展的系统, 建构以元知识为核心的多元文化能力模型将有助于深入理解全球化问题。新模型的效用检验计划从文化知识管理和群际接触应对两方面检验多元文化能力在跨文化合作情境中的效用与机制, 以期为全球化环境中个人与组织开展跨文化交流与合作的实践提供理论指导。     

公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

术后乳腺癌患者体象对创伤后应激障碍和创伤后成长的影响：反刍的中介作用

为探讨乳腺癌患者反刍这一认知情绪调节方式在体象和创伤后应激障碍（PTSD）、创伤后成长（PTG）之间的中介作用,采用体象量表（BIS）、认知情绪调节问卷中文版（CERQ-C）、创伤后应激障碍量表（PSS）和创伤后成长问卷（PTGI）对150名乳腺癌术后患者进行研究。结果发现：（1）乳腺癌患者的体象可以正向预测PTSD和PTG;（2）乳腺癌患者的反刍在体象和PTSD的闯入性症状、回避性症状中起中介作用,在体象与PTG中的中介作用不显著。结果表明,体象既可以正向预测乳腺癌患者的PTSD和PTG,也可以通过反刍的中介作用影响PTSD。     

Procedural justice and social regulation across group boundaries: does subgroup identity undermine relationship-based governance?

The relational model of authority suggests that people are inclined to accept the decisions of ethnic outgroup authorities when they identify with a superordinate category they share with the authority, and when the authority satisfies their relational justice concerns. Using responses from a random sample of African Americans, Latinos, and Whites about their cross-ethnic interactions with legal authorities, the findings indicated that those who are highly identified with the superordinate category of America indicate greater reliance on relational concerns and less on instrumental concerns when evaluating the authority's decision. In contrast, identification with one's ethnic subgroup did not moderate the linkage between relational concerns and acceptance. Across all ethnic groups, there were positive rather than negative correlations between measures of American and ethnic identity. Together, these findings indicate that subgroup identity does not undermine the relational basis of social regulation and that relationship-based governance is compatible with multiculturalism.     

Brain potentials elicited by matching global and occluded 3-dimensional contours

Subjects were instructed to match 3-dimensional forms while event-related potentials (ERPs) were recorded to explore the relationship between visual completion and conflict processing. Sequentially presented paired stimuli (S1 and S2) were identical in condition I, while in condition II the images were of the same contour, but S2 contained an invisible portion, and in condition III S1 and S2 were of different contours. Subjects indicated if stimuli were physically identical or contour similar in two separate sessions. Following the onset of S2, ERP components P100, N150, and LPC were recorded in all conditions. N150 was enhanced in condition II in both sessions, and N270 was elicited in conditions II and III. N150 is related to visual completion, while N270 is related to the evaluation of information discrepancy, belonging to independent systems.     

视觉形状知觉在近似数量系统和计算流畅性关系中的作用

已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。
