权力感对风险决策框架效应的影响

框架效应是指由于对事物描述方式的改变而引起决策者偏好反转的现象。以权力的接近-抑制理论以及模糊痕迹理论为基础,研究探索了权力感对风险决策框架效应的影响及其发生机制。实验一通过回忆法对170名学生被试进行权力操纵,综合运用四种类型的决策情境,研究考察了权力感与框架效应的关系。结果发现,高权力组被试的框架效应显著,低权力组被试者的框架效应不显著。实验二探讨权力感与框架效应的内在机制。结果发现,信息加工深度中介权力感与框架效应之间的关系     

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.

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".     

语音信息对不同水平中国英语学习者语义加工的影响

研究通过同音异义词对被试判断句子语义正误的干扰实验,来考查语音信息对不同英语水平的中国英语学习者语义加工的影响。实验结果发现,英语水平较高的中国被试所受到的同音异义词的干扰较大,而英语水平普通的被试受到的干扰很小。这一结果说明,英语学习者的水平越高,其语音信息的使用程度越高。     

Complex Systems from the Perspective of Category Theory: II. Covering Systems and Sheaves

Using the concept of adjunction, for the comprehension of the structure of a complex system, developed in Part I, we introduce the notion of covering systems consisting of partially or locally defined adequately understood objects. This notion incorporates the necessary and sufficient conditions for a sheaf theoretical representation of the informational content included in the structure of a complex system in terms of localization systems. Furthermore, it accommodates a formulation of an invariance property of information communication concerning the analysis of a complex system.     

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.     

Explaining after by before: Basic aspects of a dynamic systems approach to the study of development

The basic properties of a dynamic systems approach of development are illustrated by contrasting two simple equations. One, y_t+1 = f (y_t), is characteristic of dynamic systems models. The other, y_i = f (x_i), refers to what, for the sake of simplicity, is referred to as the standard developmental approach. We give illustrations from cognitive, language and social development to show the characteristic differences of these two types of models and show their complementarity. The article further compares the “Bloomington” with the “Groningen” approach to dynamic systems theorizing in developmental psychology. It continues with a discussion of two important questions. One involves the issue of measurement and the nature of developmental variables from the viewpoint of dynamic systems. The second concerns the question of short- and long-term time scales in developmental models, which is discussed on the basis of an example, namely dyadic interaction of young children in the context of different social statuses.
