中国人人格量表(QZPS)的编制过程与初步结果 总被引:92,自引:10,他引:82
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 相似文献

东西方面孔异族效应机理的电生理学证据 总被引:5,自引:1,他引:4
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” 相似文献

汉语图片命名中获得年龄的作用 总被引:6,自引:0,他引:6
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。 相似文献

Contextual learning induces an increase in the number of hippocampal CA1 neurons expressing high levels of BDNF 总被引:3,自引:0,他引:3
Chen J Kitanishi T Ikeda T Matsuki N Yamada MK 《Neurobiology of learning and memory》2007,88(4):409-415
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. 相似文献

Bryan S. Turner 《Contemporary Islam》2007,1(2):123-137
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. 相似文献

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. 相似文献

The dimensional change card-sorting task (DCCS) is used to assess the executive abilities of young children. Typically, 3-year-olds have difficulty in performing this task. However, the exact nature of this difficulty is still being debated. In the standard DCCS, children need to sort, for example, test cards with a blue flower or a red car into two boxes marked with the target cards. The 3-year-olds commonly have pronounced difficulty in switching from one sorting criterion (e.g., color) to another (e.g., shape). Here two experiments with 3-year-olds showed that making the transition between the sorting criteria more distinct improved performance significantly. This was achieved by taking away the target cards for a brief time period, asking a question irrelevant to the task, and pretraining the children by redescribing the test cards. 相似文献

The goal of this study was to examine incidental and intentional spatial sequence learning during middle childhood and adolescence. We tested four age groups (8-10 years, 11-13 years, 14-17 years, and young adults [18+ years]) on a serial reaction time task and used manual and oculomotor measures to examine incidental sequence learning. Participants were also administered a trial block in which they were explicitly instructed to learn a sequence. Replicating our previous study with adults, oculomotor anticipations and response times showed learning effects similar to those in the manual modality. There were few age-related differences in the sequence learning indexes during incidental learning, but intentional learning yielded differences on all indexes. Results indicate that the search for regularities and the ability to learn a sequence rapidly under incidental conditions are mature by 8 to 10 years of age. In contrast, the ability to learn a sequence intentionally, which requires cognitive resources and strategies, continues to develop through adolescence. 相似文献
