Improving judgmental forecasts with judgmental bootstrapping and task feedback support

This study examines the utility of two widely advocated methods for supporting judgmental forecasts—providing task feedback and providing judgmental bootstrapping support. In a simulated laboratory based experiment that focused on producing composite sales forecasts from three individual components, we compared the effectiveness of these two methods in improving final judgmental forecasts. In the presence of cognitive feedback task, feedback led to better forecasts than providing judgmental bootstrap forecasts. Simply providing bootstrap forecasts was of no additional benefit over a control condition. This was true in terms of the Brunswik Lens model measures of achievement, knowledge, and consistency, and in terms of forecast accuracy. This occurred both in stable environments and when special events (unusual one‐time events requiring adjustments to the forecasts) arose. Copyright © 2005 John Wiley & Sons, Ltd.     

青少年的人格特征与互联网娱乐服务使用偏好的关系

利用互联网进行娱乐已经成为了一种全新的时尚,如何使成长中的青少年不在这个虚拟的娱乐世界中“玩物丧志”,需要我们充分地了解使用互联网娱乐服务过程中的基本现象,有的放矢地对青少年的网上行为进行疏导.该研究通过对339名中学生进行问卷调查,对青少年的人格特征、社会支持与互联网娱乐服务之间的关系进行了探讨,结果表明:(1)客观社会支持、主观社会支持对互联网娱乐服务的使用偏好有着直接的正向作用;而对社会支持的利用对互联网娱乐服务的使用偏好有着直接的负向作用;(2)宜人性、外向性均可以通过客观社会支持、主观社会支持和对社会支持的利用间接地影响互联网娱乐服务的使用偏好;(3)客观社会支持会影响主观社会支持,主观社会支持对社会支持的利用水平也有影响.     

医学人文社科系列课程的整合优化及教学模式改革

医学院校人文教育主要存在观念上的唯科学取向、内容上的唯知识取向、方法难输化和组织形式化等弊端.提出促进学科间的交叉融合是高校医学院校人文科学课程改革的根本目的之一.以学科为基础的实质性融合是人文学科体制改革的基本点.

浅谈内隐社会认知的研究与现状

内隐社会认知是无意识思想、认知理论和社会心理研究日渐整合的结果。作为认知心理学研究的一个组成部分,内隐社会认知的研究从方法论上,得益于内隐记忆研究中逐步完善的间接测量方法;从内容上,尽管内隐社会认知的研究还比较初浅,但却已经涵盖了社会认知、社会态度以及归因评价的多个方面。     

价值观与大学生寻求社会支持的关系研究

在大学学习阶段,各种青年期不可避免的问题和大学生所特有的紧张与压力极大地影响着大学生的健康成长。尽管家长、同学、老师和朋友都可能为他们提供有效的社会支持与帮助,然而他们在遇到困难或烦恼时却很少主动寻求帮助,造成这种现象的原因是多方面的,如个体需要帮助的原因,个人价值观、对自我的评价、对帮助者意图的分析等,本文主要研究和探讨了价值观对大学生寻求社会支持与帮助的影响,并初步揭示了它们之间的相互关系。     

L'interprétation d'indices non verbaux par les enfants

Interpreting appropriately face expressions and analyzing social relations between people, according to their actions are useful competence for treating pragmatic aspects of communication. We do research on these competences by presenting a recognition emotion task, and a task in which movements of geometrical figures simulate social interaction, to 98 children (children aged 8, 10, 12 and 14 years, children with autism and mental retardation). Results show that answers qualitatively increase with age, even after 12 years. Children with autism encounter more difficulties to recognize emotional expression than to attribute intentional actions. Emotion recognition is related to simple intention attribution but not with complex one, which develops later.     

Indirect aggression in the media: A content analysis of british television programs

The purpose of this study is to determine how much indirect aggression occurs in television programs popular among British adolescents. Previous research has mainly focused on violence in the media rather than examining this more manipulative and subtle type of aggression. A content analysis of 228 hours of television programming revealed that indirect aggression was portrayed in 92.04% of all episodes analyzed. It was portrayed more frequently than physical and verbal aggression. Females were more likely to be shown as indirect aggressors than were males, while males were more likely to be portrayed as physical aggressors. Attractive aggressors were more likely to use indirect than other types of aggression. Indirect aggression was often found to be justified, realistic, and rewarded. We conclude that programs that are not considered violent may still contain a large amount of other types of aggression. Aggr. Behav. 30:254–271, 2004. © 2004 Wiley‐Liss, Inc.     

Behavioral profile of L‐655,708, a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit,in social encounters between male mice

GABA‐A receptor is a transmembrane hetero‐oligomeric protein which consists of five subunits, the combination of which confers unique pharmacological properties to the receptor. It is well‐known that the GABAergic system is involved in the modulation of aggression. However, the role of α5/GABA‐A receptors has not been explored. In this study, we examined the effect of L‐655,708 (0.625‐5 mg/kg), a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit, on agonistic behavior elicited by isolation in male mice. Individually housed mice were exposed to an anosmic “standard opponent” 30 min after drug administration, and the encounters were videotaped and evaluated using an ethologically based analysis. L‐655,708 (5 mg/kg) exhibited an ethopharmacological profile characterized by a marked reduction of the time spent in offensive behavior (threat and attack) without affecting immobility, accompanied by a significant increase of avoidance/flee and nonsocial exploration behaviors, suggesting that the antiaggressive effect of the drug is unselective. Overall, this behavioral profile might indicate the existence of an anxiogenic‐like activity of L‐655,708 in mice. Aggr. Behav. 30:319–325, 2004. © 2004 Wiley‐Liss, Inc.     

Social Dominance Theory: Its Agenda and Method

The theory has been misconstrued in four primary ways, which are often expressed as the claims of psychological reductionism, conceptual redundancy, biological reductionism, and hierarchy justification. This paper addresses these claims and suggests how social dominance theory builds on and moves beyond social identity theory and system justification theory.
