团体决策支持系统和团体讨论对团体决策的影响

通过模拟实验的方法,探讨了团体决策支持系统（GDSS）和团体讨论对团体决策的影响。以大学生为被试,运用小组决策任务,对小组决策过程进行了研究。实验记录了在有无GDSS的支持和有无团体讨论两个变量所决定的4种实验条件下,小组决策取得结果的正确性和组内的一致性。用ANOVA方法分析了4种条件下的实验结果,发现GDSS能提高团体决策的正确性,而团体讨论将有助于成员做出一个正确的、一致的决策     

中国人人格量表（QZPS）的编制过程与初步结果

旨在编制能够反映中国人人格结构特点的中国人人格量表（QZPS）。文中首先分析了直接采用或修订西方人格量表的问题和潜在危险,以及目前国内使用的各种人格量表存在的局限;按照人格研究的“词汇学假设”,根据杨国枢和王登峰（1999）以及后来的研究所确定的中国人人格结构的七因素模型,提出了QZPS的编制原则和操作程序。按照人格特质形容词的含义编写测量项目,并根据小因素和大因素的含义对项目进行修改,初步确定了1600多个项目。经2280名被试的评定,初步筛选出409个项目。再经1099名被试评定,确定了215个项目构成QZPS,测量中国人人格的7个维度和18个小因素。文中还报告了对QZPS的项目分析的结果     

东西方面孔异族效应机理的电生理学证据

采取事件相关电位方法研究东西方面孔记忆编码的差异（DM效应）,从而阐明异族效应的神经机制。14名被试学习和再认东西方面孔照片的实验结果表明,无论记住与否,西方面孔产生的早期成分（潜伏期70~220ms）在头皮额部有一个比东方面孔更为正向的变化,表明在此阶段更多的资源分配于异族面孔,支持异族效应产生的特征选择假说。无论东方面孔还是西方面孔,记住与未记住相比较,则在额部和顶部产生潜伏期在晚期正成分（LPC）范围的正走向变化,但西方面孔在240~320ms潜伏期范围内,DM效应较小。另外,东方面孔在枕部诱发出一个明显的负波N260,而西方面孔产生的N260很小甚至没有,反映了大脑对不同种族面孔的编码机制有所不同,因而可能被称为“种族特异波”     

应用层次分析法建立最优心理结构的探讨

层次分析法是一种新的将定量分析与定性分析相结合的系统分析与决策方法。通过分析当前在心理系统中应用层次分析法存在的问题,首次提出了应用层次分析法来为心理系统建立最优心理结构的设想。应用这种方法要求所研究的心理系统必须有操作性定义,并能形成判定“最优心理结构”的统一标准,因此这种方法特别适用于心理量表。文章通过一个例子具体介绍了如何应用层次分析法的基本思想和计算方法来给心理量表中的各个维度赋予理想化的权值及其进一步应用与验证的方法。     

汉语图片命名中获得年龄的作用

不同语种的研究都发现获得年龄是影响图片命名和词汇命名的重要因素。该研究对汉语图片命名中获得年龄的作用进行了初步探讨。研究分为两部分,第一部分让20名大学生对187幅选自Snodgrass和Vanderwart图片集的线条画的名称的获得年龄进行了评定;第二部分以该187幅图片为刺激,30名大学生被试对图片进行命名反应。以命名反应时为因变量,采用多重回归分析,发现除了名称一致性和概念熟悉性,获得年龄是图片命名反应时的主要预测指标,并没有发现词频的效应。文章对此结果进行了讨论。     

Contextual learning induces an increase in the number of hippocampal CA1 neurons expressing high levels of BDNF

We examined behaviorally induced expression of brain-derived neurotrophic factor (BDNF) in area CA1 of the hippocampus. Sprague-Dawley rats were trained in a contextual fear conditioning (CFC) task, sacrificed 4h later, and their brains were processed for immunohistochemistry. We found distinctively high levels of BDNF immunoreactivity in a small number ( approximately 1%) of CA1 neurons in untrained animals. The number of these exceptional neurons, which are identified as BDNF(++) in this study, was increased by up to approximately 3% after CFC. This increase was blocked in the presence of a memory-impairing dose of a NMDA receptor antagonist (MK801 0.3 mg/kg, i.p.) given 30 min prior to training. The BDNF signal intensity in BDNF(++) neurons correlated with that of surrounding glutamic acid decarboxylase (GAD) 65. This correlation between GAD65 and BDNF signal intensities suggests that BDNF upregulation was associated with increased signaling via inhibitory GABAergic synapses that would lessen further intervening neuronal activity. Our observation that neurons which upregulate BDNF expression following a learning experience are rich in GAD65-enriched afferent synapses suggests that these neurons may have distinct roles in memory consolidation.

Managing religions: state responses to religious diversity

After 9/11 there is a general sense of the crisis of liberalism and secularism, and the need for greater security and surveillance. Diasporic Muslim communities have been increasingly the target of government interventions and investigations, resulting in various forms of governmentality that in fact constitute a ‘management of Muslims.’ The traditional strategies of benign neglect have been replaced by periods of intense governmental activity. The idea of ‘managing Muslims’ is often disguised by a more neutral terminology such as pluralism or multiculturalism. This article examines two versions of the management of religions from policies of ‘upgrading’ or retraining of Muslims for modernity to more robust policies of containment, rendition and seclusion. The result of securitisation and globalisation is the rise of a new type of society that I call ‘the enclave society.’ In such societies governments are creating new policies of ‘enclavement’ to quarantine communities that are undesirable or unwanted or dangerous. The mobility of a global society is now being constrained by encirclement and enclavement through building walls, ghettoes, catchments and no-go areas. Such policies are likely to be counter productive, requiring an escalation of draconian interventions.     

The contributory role of worry in emotion generation and dysregulation in generalized anxiety disorder

The role of worry in generalized anxiety disorder (GAD) has been posited to serve as an avoidance of emotional experience, and emotion regulation deficits in GAD have been found in several previous studies. It remains unclear whether those with GAD experience more dysregulated emotions during periods of euthymia and positive affect or whether these deficits occur only during periods of worry. Individuals with GAD (with and without co-occurring dysphoria) and non-anxious controls were randomly assigned to receive a worry, neutral, or relaxation induction. Following the induction, all participants viewed a film clip documented to elicit sadness. Intensity of emotions and emotion regulation were examined following the induction period and film clip. The results revealed that, regardless of co-occurring dysphoria, individuals with GAD in the worry condition experienced more intense depressed affect than GAD participants in the other conditions and controls participants. In contrast, presence of worry appeared to have less impact on indices of emotion dysregulation, which were greater in participants with GAD compared to controls, but largely insensitive to contextual effects of worry or of relaxation. Following film viewing, both GAD participants with and without dysphoria displayed poorer understanding, acceptance, and management of emotions than did controls. However, acceptance and management deficits were most pronounced in individuals with both GAD and co-occurring dysphoria. Implications for the role of emotions in conceptualization and treatment of GAD are discussed.
