情绪加工老龄化已经成为老龄化研究的新热点, 但其内在机制仍然缺乏统一的解释。本研究以自动加工和控制加工为切入点, 综合行为实验、ERP和fMRI实验技术, 开展表情加工的老龄化研究, 从情绪与认知交互的角度进一步揭示情绪加工老龄化的内在机制。具体内容包括表情自动加工和控制加工的年龄差异及其神经机制, 表情自动加工与认知控制的相互作用, 以及个体差异在情绪加工老龄化中的作用等。本研究将加深对情绪加工老龄化的理解, 为相关理论模型的验证、修正和完善提供实证依据。  相似文献

操作条件下的记忆效果好于语词条件下记忆效果的现象被称为动作记忆SPT效应。以往研究先后提出非策略加工、多通道加工、动作编码及情景整合理论来解释SPT效应,但这些理论解释仍存在矛盾和分歧,并阻碍了当前动作记忆领域的研究进展。为了解决目前的理论困境,本文详细地阐述了各理论的核心内容、发展历程及其存在矛盾和分歧的原因,并提出应以加工过程与加工对象相结合的视角来建立新的理论模型,以进一步促进实证研究的展开。  相似文献

本研究通过设置隐含算术策略的问题情境,比较不同顺序和设置条件的进程段行为反应和ERP数据差异,考察被试在不断练习条件下对隐含策略的习得过程及迁移应用特点。结果:被试在对隐含策略无意识的情况下,第1-4练习进程段的反应时、错误率显著低于第5进程段(探测段)。同时,不同进程段诱发的部分ERPs特征也呈现有规律的变化。结论:在存在隐含策略的算术策略任务情境中,通过练习人们可以在无意识情况下逐渐生成内隐策略,诱发的ERP成分P200、N400s可以部分地反映其生成过程。已生成的内隐策略,能部分地应用到相应的新情境中。  相似文献

创伤后成长(Post-traumatic Growth, PTG)是指人们在经历了严重的压力性生活事件或创伤性事件后, 由于对抗压力所引起心理的积极变化。本研究对国外创伤后成长进行归纳概括, 论述了促进创伤后成长的影响因素, 如人格特质、社会支持、益处寻求和意义建构。此外, 归纳了基于不同视角的PTG模型, 提出了促进PTG的干预策略, 针对PTG实证研究中某些相关变量的测量问题提出改进意见。未来应着重于开展具备多个评估点的纵向研究, 建构适用于不同人群的PTG理论模型。  相似文献

目前参数估计多采用统计方法,存在耗时长、要求被试样本容量大和项目数多等缺点。本文将BP神经网络和降维法相结合,对GRM的项目参数和考生能力参数进行估计。蒙特卡洛模拟结果显示:(1)不管是人多题少还是题多人少,该网络设计下的参数估计精度都较高;(2)可以应用到多个不同等级评分的参数估计中,甚至是超过15个等级的项目参数,估计精度也较高,这是其他参数估计方法所不可比拟的;(3)运行的时长和统计估计方法相比大大缩减。  相似文献

Considerable evidence supports the sequential two-system (“default interventionist”) model of moral judgement, as proposed by Greene and others. We tested whether judgement speed and/or personal/impersonal moral dilemmas can predict the kind of moral judgements (utilitarian or deontological) subjects make for each dilemma, and whether personal dilemmas create difficulty in moral judgements. Our results showed that neither personal/impersonal conditions nor spontaneous/thoughtful-reflection conditions were reliable predictors of utilitarian or deontological moral judgements. Yet, we found support for an alternative view, in which, when the two types of responses are in conflict; the resolution of this conflict depends on both the subject and the dilemma. While thinking about this conflict, subjects sometimes change their minds in both directions, as suggested by the data from a mouse-tracking task.  相似文献

Deep learning is associated with the latest success stories in AI. In particular, deep neural networks are applied in increasingly different fields to model complex processes. Interestingly, the underlying algorithm of backpropagation was originally designed for political science models. The theoretical foundations of this approach are very similar to the concept of Punctuated Equilibrium Theory (PET). The article discusses the concept of deep learning and shows parallels to PET. A showcase model demonstrates how deep learning can be used to provide a missing link in the study of the policy process: the connection between attention in the political system (as inputs) and budget shifts (as outputs).  相似文献

The present study aimed to validate the Rosenberg Self-Esteem Scale (RSES) in Burundi, through a multi-strategy approach used in cross-cultural studies. Respondents were 906 health workers (men = 56%; caregivers 60%). They responded to a bilingual version of RSES. We utilised Confirmatory Factorial Analysis (CFA) with structural equation modelling and a back translation test to explore the structure of the RSES and the reliability of scores from the scale. Data from an independent sample were analysed for the reliability of scores assessment. CFA results suggested that the global RSES factor was likely contaminated by a method-effect; mainly associated with negatively worded items. Internal consistencies and a back-translation test demonstrated that the negatively worded items were unsuitable in this context. The independent sample study confirmed poor reliability and internal consistency of scores for both alternative language versions of the RSES. Our data suggested that an overall cultural effect, rather than a merely specific language effect, may undermine the cross-cultural transportability of the Western scale.  相似文献

The overall aim with the study was to describe the knowledge building that was developed in a group of students who were trained nurses enrolled in a Swedish higher education programme. With a point of departure in an interactive research approach, the authors applied the dialogue seminar as method and pedagogical model. When the students in close to practice talks, shared their thoughts about how gender and gender equality could be experienced and understood, the dialogue seminar became useable. At the analysis of the stories which the students shared at the dialogue seminars, it became clear that most of the students had an ambivalent approach to gender equality. When they reflected on gender relations, they brought out the hierarchical and separate gender relations which they experienced as existing within healthcare. Furthermore, their professional lives seemed to be embedded in gender-related practices. An important conclusion is that the students’ reflections oscillated between critical reflection on conditions and critical reflection on processes within their own practice in healthcare. Another finding was that the students’ reflections in dialogue form became important in a learning process, not least in the light of that gender relations and gender equality only to a limited degree had been included in their nurse’s education at the basic level.  相似文献

The objective of this study was to validate the new Social Axioms Survey II (SASII). The study sample comprised university students (n = 793) as well as their family members and friends (n = 645). Confirmatory factor analysis (CFA) following an initial exploratory factor analysis yielded a five-factor model: social cynicism, social complexity, reward for application, religiosity, and fate control. The findings of this study support the use of the new SASII in South Africa for research purposes.  相似文献
