A Non-alethic Multi-agent Doxastic Logic as a Solution to Epistemic Conflicts

Axiomathes - The non-alethic systems N1 of da Costa and A of Grana are both paraconsistent and paracomplete. Based on them, a multi-agent doxastic logic NADK can be obtained by logical expansion....

Episodic Future Thinking Reduces Delay Discounting of Gains and Losses: The Role of Regulatory Focus1,2

We examined the moderating effect of regulatory foci on the efficacy of episodic future thinking in reducing delay discounting. We hypothesized that the impact of imagining positive future events (vs. recent positive events) on delay discounting of gains would be stronger for individuals with a high promotion focus than for those with a high prevention focus (Hypothesis 1). Conversely, the effects of imagining adverse future events (vs. recent negative events) on delay discounting of losses would be stronger for individuals with a high prevention focus than for those with a high promotion focus (Hypothesis 2). We conducted two experiments in which participants, randomly allocated to episodic future thinking (EFT) or episodic recent thinking (ERT) groups, completed a delayed discounting task of gain (Experiment 1) or loss (Experiment 2). Experiment 1 (N = 73) weakly supported Hypothesis 1; Experiment 2 (N = 99) did not support Hypothesis 2. Our findings suggest positive EFT is particularly effective for individuals with a high promotion focus compared to individuals with a high prevention focus, which further reveals how EFT attenuates delay discounting.

不同视觉区域OUP效应的眼动研究

摘 要 采用眼动方法,通过两个实验考察了不同视觉区域的OUP效应。结果显示：（1）当刺激材料分别平行呈现于左侧视觉区域和右侧视觉区域时,在右侧视觉区域产生了OUP效应,而在左侧视觉区域没有OUP效应,我们假设是由于左侧视觉区域首字母距离中央凹的不利位置影响了OUP效应的产生。（2）当垂直方向呈现刺激时,在两侧视觉区域均产生了明显的OUP效应,表明首字母距离中央凹处于有利位置时不会影响OUP效应的产生。实验结果支持了大脑左半球和右半球在词汇识别时的策略为系列加工,对左半球平行加工右半球系列加工的结论提出了质疑。     

Bayesian estimation of semiparametric nonlinear dynamic factor analysis models using the Dirichlet process prior

Parameters in time series and other dynamic models often show complex range restrictions and their distributions may deviate substantially from multivariate normal or other standard parametric distributions. We use the truncated Dirichlet process (DP) as a non‐parametric prior for such dynamic parameters in a novel nonlinear Bayesian dynamic factor analysis model. This is equivalent to specifying the prior distribution to be a mixture distribution composed of an unknown number of discrete point masses (or clusters). The stick‐breaking prior and the blocked Gibbs sampler are used to enable efficient simulation of posterior samples. Using a series of empirical and simulation examples, we illustrate the flexibility of the proposed approach in approximating distributions of very diverse shapes.     

任务难度与老化对大脑激活的影响——以线索记忆编码为例

以汉语名词双字词对为材料,采用了两种性质、三种难度水平的线索回忆任务对12名老年被试和15名年轻被试的项目记忆编码过程进行fMRI扫描,考察在编码阶段大脑激活受任务难度变化和老化的影响。行为研究结果发现:年龄的主效应、难度的主效应以及难度与年龄交互作用均显著,即,随着任务难度的增加,老年人的成绩更加明显地低于年轻人。神经成像研究结果发现:(1)当词对的相关性降低时,大脑激活的增强主要表现为面积的增加,而当词对的频率降低时,主要表现在激活强度的增加上。(2)任务难度和大脑激活面积、强度之间均不存在对应的递增变化关系。(3)仅当词对的相关性降低时,老年人比年轻人调用了更多的额叶脑区。     

心理健康素质测评系统·中国成年人人际健康素质量表的编制

在文献分析和专家评定的基础之上,构建了人际健康素质的基本结构,并编制了初始的中国成年人人际健康素质问卷。然后通过项目区分度分析和验证性因素分析对初始问卷进行了修订,最终形成了包括合群性、亲仁性、利他性、共情性和友善性5个维度的正式量表。结果表明,人际健康素质量表具有较高的内部一致性信度、重测信度和分半信度以及较好的内容效度、结构效度、校标关联效度和会聚效度。结论：人际健康素质量表具有较好的心理测量学特征,可以作为中国成年人人际健康素质的心理测量工具。     

寻求专业性心理帮助的预测因素研究的综述

在日常生活中,一些人在产生了自己难以解决的心理问题时,不寻求专业性心理帮助,以致使心理问题变得更加严重,这一问题已经引起了国内外不少学者的关注。他们运用各种问卷和访谈的方式,从分析求助者个人心理特点入手,并通过跨文化研究,揭示了人格特质和社会文化对心理求助的预测作用以及与心理咨询工作者有关的因素。该文概述并讨论了国内外关于此课题的研究成果,以期为我国的心理健康教育提供有价值的资料。
