Repressive coping and cardiovascular reactivity to novel and recurrent stress

Background and objectives: Repressors tend to report less negative emotion and to describe challenges as less stressful, yet tend to exhibit higher rates of cardiovascular disease. While repressive coping has been shown to be associated with exaggerated physiological reactivity to novel stress, we sought to establish if elevated responses persisted across repeated exposure.

Design and methods: In a sample of 86 healthy female adults, a verbal-autonomic response dissociation index of repressive coping was computed. Participants were exposed to two consecutive stress tasks, with analyses based on comparisons of consecutive stress responses.

Results: Analysis of covariance demonstrated significant differences across the study on diastolic blood pressure and cardiac output, as a function of repressive coping. Repressors showed elevated reactions to both stress tasks; however, cardiac output responses to the second task were more muted indicating that repressive coping was associated with successful adaptation to recurrent stress. Nevertheless, repressive copers maintained an exaggerated cardiovascular responses to recurrent stress.

Conclusions: The present study identifies that repressive coping may be associated with increased risk of cardiovascular disease development through elevated cardiovascular reactions to both novel and recurrent stress.     

解释水平视角下的乐观偏差效应

研究基于解释水平理论,考查心理距离对乐观偏差效应的影响。实验从心理距离的事件概率维度、时间距离维度、空间距离维度入手,采用自编的材料对677名被试进行测量,探讨心理距离的远近对乐观偏差产生的影响。结果表明,被试对未来生活事件的判断存在总体上的乐观偏差。在较远的心理距离条件下,被试表现出更大的乐观偏差;而在较近的心理距离中,乐观偏差效应明显减小。但在时间距离维度以及消极事件的概率维度上,表现出与总体乐观偏差不一致的现象。     

不同反应重复量对反应抑制后效应的影响*

研究不同反应重复量对反应抑制后效应的影响。采用停止信号范式,让被试完成不同反应重复量的反应抑制任务。结果显示,总的来说反应重复量因素和重复类型因素的主效应都显著;信号抑制条件下重复一次后比重复三次后无信号试次反应时要显著地长,但都与总的无信号试次反应时没有显著差异;信号反应条件下重复三次后与重复一次后无信号试次反应时没有显著差异,但都比总的无信号试次反应时显著地长。结果表明,不同反应重复量反应抑制后效应在信号抑制条件下既有认知控制调整也有自动化记忆提取,在信号反应条件下仅存在认知控制的执行加工。     

Psychological correlates of peer victimisation in preschool: social cognitive skills,executive function and attachment profiles

Most research into peer victimisation has focussed on children aged 8 years and above and has included a study of the correlates of victimisation, including cognitive and social skills, and attachment profiles. Recent research has started to investigate aggression and victimisation in younger groups and has found that the nature of aggression differs from that in older children in terms of the types of victimisation involved and the stability of the roles. This study investigated some of the correlates of roles taken in victimisation in 104 children aged 4–6 years, using a cartoon methodology to elicit peer nominations for aggressor, victim, and defender. It examined the social cognitive abilities, executive function skills, and attachment profiles of aggressors, victims, and defenders. Victims did not exhibit poor performance on the social cognitive tasks or have insecure attachment qualities as has been found with victims during middle childhood. Aggressors did not perform highly on the social cognitive tasks in contrast to older aggressors and bullies. Defenders were found to perform above average (although not significantly different from other groups) on the social cognitive tasks. These findings are related to the nature of aggression and victimisation at this age, and a developmental change hypothesis is proposed to accommodate them. Aggr.

关于流行性感冒大流行的几个问题

流行性感冒(流感)大流行的发生是有其生物学和社会学基础的,从现在至未来很长的时间内,流感大流行的再现是不可避免的。但是人类在疫灾面前没有必要恐慌,主动、积极、科学的应对,可以把流感大流行对人类和人类生活的危害程度减至最低。     

基督教伦理理论的两种类型

在西方基督徒中间,对与性、家庭生活和医学伦理问题相联系的个体道德问题,存在着严重的分歧.因为在今天的基督徒中间存在着两种伦理理论决定着他们的观点,第一种道德判断是"道义论",另一种道德判断叫做"后果主义".     

Children's understanding of mental states as causes of emotions

Theory of mind studies of emotion usually focus on children's ability to predict other people's feelings. This study examined children's spontaneous references to mental states in explaining others' emotions. Children (4‐, 6‐ and 10‐year‐olds, n = 122) were told stories and asked to explain both typical and atypical emotional reactions of characters. Because atypical emotional reactions are unexpected, we hypothesized that children would be more likely to refer to mental states, such as desires and beliefs, in explaining them than when explaining typical emotions. From the development of lay theories of emotion, derived the prediction that older children would refer more often to mental states than younger children. The developmental shift from a desire‐psychology to a belief‐psychology led to the expectation that references to desires would increase at an earlier age than references to beliefs. Our findings confirmed these expectations only partly, because the nature of the emotion (happiness, anger, sadness or fear) interacted with these factors. Whereas anger, happiness and sadness mainly evoked desire references, fear evoked more belief references, even in 4‐year‐olds. The fact that other factors besides age can also play an influential role in children's mental state reasoning is discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

The hybrid split ad technique and onsite rewards

With a ‘split ad’, information is presented as two distinct parts, such as when two short commercials for a given brand are separated by other television content. Two studies are presented in this paper which demonstrate the advantages of an emerging form of the split ad strategy, which is termed the ‘hybrid split ad’ technique. Using this approach, a message typically begins in a traditional medium and then concludes at a website. In Experiment 1, the hybrid split ad technique is shown to enhance attitudes towards an advertised product by increasing the perceived importance of favourable attributes provided at the website. Experiment 2 replicates this finding and also addresses an issue of managerial importance, namely, how to motivate consumers to pursue the second (web‐based) portion of the ad. Offering consumers an incentive at the website is useful in this regard, provided that the incentive is small enough not to undermine the positive effects of the hybrid split ad.     

POLANYI ON TELEOLOGY: ARESPONSETO JOHN APCZYNSKI AND RICHARD GELWICK

Abstract. Michael Polanyi criticized the neo‐Darwinian synthesis on two grounds: that accidental hereditary changes bringing adaptive advantages cannot account for the rise of discontinuous new species, and that a Ideological ordering principle is needed to explain evolutionary advance. I commend the previous articles by John Apczynski and Richard Gelwick and also argue, more strongly than they, that Polanyi's critique of evolutionary theory is flawed. It relies on an inappropriate notion of progress and untenable analogies from the human process of scientific discovery and the fact that in physical systems minimal potential energy is most stable. Yet within a life of commitment to transcendent values humans can directly experience purpose and meaning, and in developing this notion Polanyi makes his greatest contribution to teleology.     

THEOLOGY AND PHYSICS FORTY YEARS LATER

Abstract. Almost forty years later I look back on a 1966 article on theology and physics by Sanford Brown and my response published with it. I reflect on his hope that theological seminaries would give attention to the methods used in scientific inquiry. I compare our comments with subsequent thought on three issues: (1) the role of models in science and religion; (2) the relation of wholes to parts in physics and other sciences and the debate over reductionism and emergence; and (3) the implications of quantum physics for theology, including the possibility of divine action at the quantum level.
