创伤后应激障碍中的非适应性泛化现象

过度泛化现象是区分普通心理问题和严重心理问题的重要指标。创伤后应激障碍(posttraumatic stress disorder, PTSD)患者在创伤事件后会出现非适应性的泛化。现有研究结果表明非适应性泛化(maladaptive generalization)可能是PTSD发生发展的一个重要因素, 但也有研究支持PTSD是导致了泛化从适应性向非适应性化转变的原因。虽然泛化现象的变化与PTSD症状的发展有相同趋势, 且具有共同的生理基础：记忆相关神经结构, 但二者之间的关系尚无明确定论。阐明PTSD与非适应性泛化之间的关系对PTSD的预测、诊断和治疗均有推进作用。     

情绪对信任的影响:来自元分析的证据

采用元分析方法探讨情绪对信任的影响。通过中英文献检索,共有21篇文章70个独立样本符合元分析标准（N=4745）。其中积极情绪对信任的影响有47个独立样本,消极情绪对信任的影响有23个独立样本。元分析的结果表明,相对于中性情绪,积极情绪对信任起到一定的促进作用,呈中等效应量（d=0.49）;消极情绪对信任起到一定的抑制作用,呈较小效应量（d=-0.23）。调节效应检验发现,情绪的诱发方式、信任对象熟悉性以及信任测量方式的调节作用均不显著。     

前瞻记忆意图后效中执行错误的机制

前瞻记忆意图后效是指已完成或取消的意图失活失败对当前认知任务造成的干扰。近期研究采用前瞻记忆任务范式探究意图后效的影响因素及认知机制。自发提取-抑制失败和预备性监控两种认知机制的分歧在于提取旧意图是否依赖注意资源的参与。脑成像研究也证实意图提取存在两条神经通路：自发提取通路和预备性监控提取通路。未来研究应探索兼容有意遗忘失败、旧意图再提取、抑制失败三者的研究范式以及降低执行错误的有效措施。     

Effectiveness of the home‐start parenting support program: Behavioral outcomes for parents and children

This study examined effectiveness of Home‐Start, a program designed to support parents with young children. The aims were (a) to examine whether Home‐Start improved maternal well‐being and (b) to examine whether Home‐Start led to changes in the behavior of mothers or children. Self‐reported and observational data were collected in two waves, using data from 54 mothers and their children between 1.5 and 3.5 years of age who participated in this intervention program for 6 months. These data were compared to 51 comparison families who reported need for parenting support. The results showed a significant improvement in perceived parenting competence, but no effects on maternal depressive moods. Mixed results were found for parenting behavior: Parental consistency and observed sensitivity improved significantly in the Home‐Start group whereas no effects were found on the other parenting variables. Child behavioral problems seemed to diminish at the second measurement in both groups, and therefore these changes cannot be attributed to Home‐Start.     

Nordic Luther Research in Motion

Abstract : Luther research in the Nordic countries is characterised by both continuation and discussion of its own legacy. Finnish Luther studies have a prominent position here, but are by no means the only actors in Nordic Luther research. Giving an overview of Nordic Luther research in the last decade, the article selects four main topics that have been the focus of special attention: politics and ethics, Communicatio idiomatum and Luther's view on language, Luther as preacher, and Luther and the gift. The article concludes with some comments on the continuing role of creation theology, so strongly emphasised in last century's Scandinavian Luther research.     

Content-specific activational effects of estrogen on working memory performance

The authors explored the influence of task content and the menstrual cycle phase on working memory (WM) performance. They addressed the content specificity of WM in the framework of evolutionary psychology, proposing a hormone-mediated adaptive design governing face perception. The authors tested 2 groups of healthy young women (n = 66 women with regular menstrual cycle, n = 27 oral contraceptive users) on a WM task with adult male or infant face photographs. Analyses of variance showed significant interaction between task content and estrogen level. Women were more efficient in solving the male faces task during high-estrogen phase of the cycle than during low-estrogen phase. No differences were found in the efficacy of solving the infant faces task between different phases of the cycle. Results suggest content-specific activational effects of estrogen on the WM performance and are consistent with the notion of a hormonal mechanism underlying adaptive shifts in cognition related to mating motivation.     

Philosophy, the “unknown knowns,” and the public use of reason

There are not only true or false solutions, there are also false questions. The task of philosophy is not to provide answers or solutions, but to submit to critical analysis the questions themselves, to make us see how the very way we perceive a problem is an obstacle to its solution. This holds especially for today’s public debates on ecological threats, on lack of faith, on democracy and the “war on terror”, in which the “unknown knowns”, the silent presuppositions we are not aware of, determine our acts.
