Probabilistic Inferences Under Emotional Stress: How Arousal Affects Decision Processes

Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress was induced through the use of highly aversive pictures immediately before each decision. Emotional state was assessed by both subjective (state anxiety, arousal, and pleasantness ratings) and objective (skin conductance) measures. The results show that emotional stress impacts decision making; in particular, emotionally aroused participants seem to have focused on the most important information and selected simpler decision strategies relative to participants in a control condition. The results are in line with the attention‐narrowing hypothesis and suggest that emotional stress can impact decision making through limited predecisional information search and the selection of simpler decision strategies.

中国癌症病人生活质量的测定──EORTC QLQ—C30在中国的试用

引进EORTCQLQ-C30,验证其在中国大陆的应用情况,为中国肿瘤学领域生活质量研究提供有效和实用的评定工具.运用随机对照实验设计,测查了289名癌症病人,结果显示各分量表中项目与所属量表的相关均高于与其他量表的相关,各分量表间呈中等偏下相关,量表因子结构分析与EORTC结果大体相似,三种方法检验的临床效度均较高.由此得出QLQ-C30各项心理测量学特性均达到要求,临床效度和实用性也比较好,在中国大陆的癌症病人中是可行的、可信的、有效的和敏感的.     

The neural bases of sport fan reactions to teams: Evidence from a neuroimaging study

This study uses neuroimaging methods to identify patterns of brain activation among sport fans in reaction to team stimuli. In a whole-brain analysis without selected regions in advance, the purposes were to identify the structures involved when fans are exposed to positive, neutral, and negative events and to learn what events activate more limbic networks. A total of 53 individuals participated in and functional magnetic resonance imaging experiment involving the presentation of videos in various situations. Findings indicate the activation of the cingulate gyrus and other structures of the limbic system, as the hippocampus and parahippocampus. We also found involvement of the ventral tegmental area of the reward system. Additionally, brain activity in emotional regulation and memory areas were more influenced by positive than neutral and negative videos. It was also found the involvement of other areas not directly included in the limbic or reward systems. This study provides the neural basis of fan reactions to team-related stimuli. Sport clubs should be aware that negative content seems to be suppressed from emotional memory and positive videos trigger more emotion and memory areas than neutral and negative videos.     

信皇历的老人

八十五营八小队,有个老年人,他信皇历。一切行动都以皇历为准,他孙子外出远行,他看皇历,择吉日才叫外出。一次孙子外出到姨娘家,老头选好了吉日。姨娘家在淮阳城里住,八十五营离城里67里路。当时,既不通车,也没有自行车,又下着大雪,得徒步行走,来回得两天。孙子起早走,第一天没回来,第二天又没回来,等到第三天又未回来,第四天老头等急了。     

青少年网络游戏行为的心理需求研究

在质的研究及理论分析的基础上,构建了16-24岁青少年网络游戏行为的心理需求模型,然后根据该模型编制问卷,进行了量的研究。探索性与验证性因素分析的结果表明:(1)青少年网络游戏心理需求问卷由现实情感的补偿与发泄、人际交往与团队归属、成就体验三个维度组成,具有良好的信度和效度指标,可以施用;(2)青少年对网络游戏的心理需求程度与其对网络游戏的使用程度显著相关。     

青少年自我描述归类与人格维度特点

对青少年自我描述的内容进行归类时发现,依据不同的归类标准会得到不同的人格结构。500多名青少年学生提供了620个不同的对自我的描述,除9个项目属于对身体和家庭状况的描述外,所有的人格特征既可以归属到中国青少年人格结构的19个二级因素,又可以归属到西方大五人格结构的30个层面。这一结果表明,外显的人格特征分类无法准确表达人格结构的实际构成,人格结构的确定还需要实证评定及对内隐结构的探索。文中还讨论了心理学研究中国化（本土化）的思路与策略。     

Measurement of self-evaluative motives: a shopping scenario

To develop measures of consumers' self-evaluative motives of Self-verification, Self-enhancement, and Self-improvement within the context of a mall shopping environment, an initial set of 49 items was generated by conducting three focus-group sessions. These items were subsequently converted into shopping-dependent motive statements. 250 undergraduate college students responded on a 7-point scale to each statement as these related to the acquisition of recent personal shopping goods. An exploratory factor analysis yielded five factors, accounting for 57.7% of the variance, three of which corresponded to the Self-verification motive (five items), Self-enhancement motive (three items), and Self-improvement motive (six items). These 14 items, along with 9 reconstructed items, yielded 23 items retained and subjected to additional testing. In a final round of data collection, 169 college students provided data for exploratory factor analysis. 11 items were used in confirmatory factor analysis. Analysis indicated that the 11-item scale adequately captured measures of the three self-evaluative motives. However, further data reduction produced a 9-item scale with marked improvement in statistical fit over the 11-item scale.     

Not all cultural values are created equal: Cultural change in China reexamined through Google books

Given its major transformations in recent decades, China has figured prominently in research on cultural change. Previous research converges in showing a general trend towards individualism in contemporary China while noting that rising individualism tends to coexist with enduring collectivism. To further understand this, we tested whether perceived traditional importance of cultural values would modulate the trajectory of cultural change reflected in word usage frequencies in published books. We re‐analysed Google's Chinese corpus since 1980 based on a broad sample of words associated with individualism–collectivism. We replicated the pattern of rising individualism and declining collectivism among words of modest and low perceived traditional importance. Most important, however, collectivistic words of high perceived traditional importance increased in usage frequencies with time, thus departing from the general trend towards individualism. Overall, our research underscores the role of core culture in cultural maintenance during times of rapid cultural change.     

从新教伦理再看传统佛教伦理的现代困境

大约100年前,中国的佛教改革家太虚和德国的社会学家马克斯·韦伯相继注意到了佛教和基督教两者与社会经济之间的亲疏关系,并对此予以了研究,但由于条件所限,研究工作均未能深入.之后近百年,东西方许多有识之士对造成佛教、佛教徒和佛教国家在适应资本主义经济生产方式方面长期落后的原因进行了探讨,这种探讨在现代社会尤其受人关注.本文通过对佛教和基督教信仰模式的对比,对形成二教经济差距的原因进行了尝试性的研究分析.
