本研究是风险认知系列研究之一 ,目的是探讨和比较企业中员工及管理人员的风险认知状况 ,以及员工与管理人员认知上的异同。研究采用问卷设计的方法。结果表明 :1员工对 2 0个风险因素的风险程度认知均超过了中性水平 ,“企业效益”仍然被知觉为最高风险点 ;2风险因素空间结构分析 ,进一步证实了风险特征变量间稳定的关系 ,同时也说明本系列研究方法上的合理性 ;3各风险特征变量间的相关 ,反映了员工风险认知中的各种特征 ;4(本研究经过信度和效度检验均达到可接受水平。     

风险沟通与公众理性

突发风险事件所导致的恐慌,其危害程度可能远远大于风险事件本身。当灾害突然降临的时候,公众能够启动理性的程度是应对危机的重要基础。文章提出了公众理性的概念,并界定和探讨了公众理性的构成以及公众理性的干扰因素;同时,通过SARS事件,着重分析了风险沟通的性质、特点,以及风险沟通对公众理性干预的可能途径和条件;目的是为总结SARS风险危机和建立应对突发风险事件的心理系统提供理论依据,以更好地促进我国在风险沟通领域的研究与实践。     

风险情景中不同成就动机者的冒险行为特征

采用计算机模拟和问卷的方法,研究不同成就动机的个体在动态情境下的冒险行为。结合成就动机的静态与动态理论,考察具有不同程度的成就动机个体在动态环境中的行为差异。结果发现,在动态情境的初期,可以看到不同成就动机的被试有稳定的偏好：成就动机高的个体偏爱中等难度的任务,成就动机低的个体偏爱较易或者是较难难度的任务;随着行为的动态进行,个体的冒险行为呈现出与静态情境中不同的规律性：成就动机高的个体在初期选择的中等难度的基础上逐渐选择更难的任务;成就动机低的个体在初期选择较易难度任务的基础上也逐渐选择更难的任务;相对于成就动机低的个体,成就动机高的个体会更慢地选择难度高的任务;高成就动机个体出现非典型转换次数显著低于低成就动机的个体。     

闽西客家地区的妈祖信仰

闽西客家山区,远离海滨,不知海舶为何物,但却普遍信仰发源莆田海滨、被沿海人民奉为海神的妈祖。本文对这个问题作了具体探讨,认为妈祖信仰传到客家山区后,对原有信仰形态有继承有改造,其被客家山区人民通过多种途经、多种方法、多种因素改造过的一种信仰形态,即传统妈祖信仰的变异形态。     

“风险”性质的探讨──一项联想测验

该实验是为探讨“风险”的性质而进行的词联想测验。实验以“风险”一词作为刺激词,让被试连续进行三次自由式联想。其结果得到了三大类不同性质的联想词及其它相关结论。     

脑电图分析的方法论

临床诊断中的脑电图分析方法可归为两大类:线性分析法与非线性分析法.本文介绍了这两类方法中常用的算法如谱估计、小波分析、混沌分析方法等,分析了这两类方法的特点、优势以及存在的不足.同时讨论了在临床应用中选取这两类方法所出现的问题.提出了将人工势场法用于脑电图分析的新思路,并对研究方案进行了可行性分析.

Clarifying the Role of Psychological Pain in the Risks of Suicidal Ideation and Suicidal Acts among Patients with Major Depressive Episodes

The role of psychological pain in the risk of suicide was explored using a three‐dimensional psychological pain model (pain arousal, painful feelings, pain avoidance). The sample consisted of 111 outpatients with major depressive episodes, including 28 individuals with suicidal histories. They completed the Chinese version of the Beck Scale for Suicide Ideation (BSI), the Beck Depression Inventory (BDI), the Psychache Scale, and the three‐dimensional Psychological Pain Scale (TDPPS). A structured clinical interview was conducted to assess the history of suicidal acts. Significant correlations were found among BDI, BSI, and TDPPS scores (p < .01). Stepwise regression analyses showed that only pain avoidance scores significantly predicted suicide ideation at one's worst point (β = .79, p < .001) and suicidal acts (β = .46, p < .001). Pain avoidance was also a better predictor of current suicidal ideation (β = .37, p = .001) than were BDI scores (β = .31, p < .01). Increased levels of pain avoidance during a major depressive episode may be a dominant component of the motivation for suicide. Future clinical assessments for populations at high risk of suicide should include measures of psychological pain to reduce the incidence of suicide.     

超文本与线性文本中元理解判断的比较

通过实验考查超文本和线性文本情境中元理解判断的异同。采用2×3的混合设计,让被试先阅读文章,然后完成元理解判断任务。结果说明,文本组织结构对细节题成绩预测和推理题成绩预测的判断值具有调节作用,超文本的非线性结构降低了元理解判断的相对准确性。     

Development of infant sustained attention and its relation to EEG oscillations: an EEG and cortical source analysis study

The current study examined the relation between infant sustained attention and infant EEG oscillations. Fifty‐nine infants were tested at 6 (N = 15), 8 (N = 17), 10 (N = 14), and 12 (N = 13) months. Three attention phases, stimulus orienting, sustained attention, and attention termination, were defined based on infants' heart rate changes. Frequency analysis using simultaneously recorded EEG focused on infant theta (2–6 Hz), alpha (6–9 Hz), and beta (9–14 Hz) rhythms. Cortical source analysis of EEG oscillations was conducted with realistic infant MRI models. Theta synchronization was found over fontal pole, temporal, and parietal electrodes during infant sustained attention for 10 and 12 months. Alpha desynchronization was found over frontal, central and parietal electrodes during sustained attention. This alpha effect started to emerge at 10 months and became well established by 12 months. No difference was found for the beta rhythm between different attention phases. The theta synchronization effect was localized to the orbital frontal, temporal pole, and ventral temporal areas. The alpha desynchronization effect was localized to the brain regions composing the default mode network including the posterior cingulate cortex and precuneus, medial prefrontal cortex, and inferior parietal gyrus. The alpha desynchronization effect was also localized to the pre‐ and post‐central gyri. The present study demonstrates a connection between infant sustained attention and EEG oscillatory activities.
