对亚里士多德主义虚构对象理论的批评

<正>虚构对象是小说、神话、传说中虚构地进行描写的对象,如福尔摩斯、哈姆雷特、孙悟空。关于虚构对象的形而上学主要研究两个基本问题:(1)我们的本体论是否应该包含虚构对象;(2)假如应该包含虚构对象,虚构对象属于什么范畴。针对问题(1),不同回答导致关于虚构对象的实在论和反实在论争论。在对问题(1)做肯定回答的基础上,对问题(2)的不同回答导致不同的虚构对象理论。虚构对象理论可分为亚里士多德主义和柏拉图主义。亚里士多德主义者认为,虚构对象并非

Modeling Not-Reached Items in Timed Tests: A Response Time Censoring Approach

Psychometrika - Time limits are imposed on many computer-based assessments, and it is common to observe examinees who run out of time, resulting in missingness due to not-reached items. The present...     

Latent variable selection in multidimensional item response theory models using the expectation model selection algorithm

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L₁ regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.     

创造性思维中语义搜索过程：基于答案累积时间函数和语义相似性的量化分析

通过描绘发散性思维测验(物品多用途, AUT)中答案生成在累积函数和语义相似性等一系列参数上的量化特征, 揭示创造性思维的语义搜索过程。结果发现：(1)新颖AUT条件中, 语义搜索呈现与自由联想类似的负加速特点, 但搜索速度较寻常AUT条件更慢。(2)新颖AUT条件中所生成的答案与题目(即物品)均具有较低的语义相似性, 且显著小于寻常AUT条件。(3)新颖AUT条件中生成的答案比寻常AUT条件表现出显著更低的聚类程度, 其中可聚类答案和未聚类答案与题目的语义相似度均较低, 且不存在显著差异, 二者在新颖性上也不存在显著差异。以上结果说明了创造性思维的语义信息搜索过程具有与自由联想类似的激活扩散特征, 但总体搜索速度较慢。新颖性要求使得个体在最初搜索时便开始摆脱题目的语义限制而进行远距离搜索(避免就近搜索), 并倾向于在每个语义场中只生成一个答案(避免局部搜索), 但也可能会在远离题目的语义场中生成多个同类别答案。     

Thinking About Thinking About Work: A Meta-Analysis of Off-Job Positive and Negative Work-Related Thoughts

Work is frequently on the minds of employees—even during evenings, weekends, and vacations. The present study is the first comprehensive meta-analysis of off-job work-related thoughts (WRTs; i.e., thoughts employees have about work when they are not at work). We were particularly interested in comparing off-job positive and negative work-related thoughts (PWRTs and NWRTs; i.e., thoughts about positive/negative work experiences or characteristics) to each other and other off-job WRT constructs, which we integrated into a typology. We coded 520 effect sizes from 171 independent samples (N = 58,682) and conducted a random-effects, individual-correction meta-analysis. We found that PWRTs and NWRTs were unrelated, and psychological detachment was negatively related to NWRTs but unrelated to PWRTs. Furthermore, PWRTs and NWRTs exhibited significantly different relationships with various antecedents (e.g., age, negative affectivity) and outcomes (e.g., work engagement, burnout). Compared to PWRTs and NWRTs, psychological detachment and problem-solving pondering exhibited generally weaker relationships with outcomes. NWRTs contaminated with negative affective strains (i.e., negative work-related thoughts and feelings) exhibited generally stronger relationships with outcomes. Overall, our meta-analytic findings indicate that PWRTs and NWRTs are different and underscore the importance of empirically and conceptually separating PWRTs and NWRTs from each other and other off-job WRT constructs. The findings also complement the nascent literature on interventions that target promoting PWRTs and reducing NWRTs.

     

被动性社交网站使用与社交焦虑：反刍思维和自我建构的作用

尽管被动性社交网站使用已经被证实为增强社交焦虑的重要风险因子,然而对其中介和调节机制依然知之甚少。当前研究旨在探索被动性社交网站使用、反刍思维、社交焦虑和自我建构的关系。614名大学生自愿参与了当前研究,并完成了一份包含被动性社交网站使用、反刍思维、社交焦虑和自我建构问卷的测验。结果表明被动性社交网站使用正向预测社交焦虑,而反刍思维完全中介了两者间的联系。调节分析表明自我建构调节了被动性社交网站使用对反刍思维的影响。条件间接效应分析进一步表明反刍思维的完全中介作用仅存在于依存型个体中。当前研究有助于加深对被动性社交网站使用如何影响个体社交焦虑的理解。     

样例呈现方式对概念训练类别表征的影响

以往研究发现训练形式会影响类别学习的表征方式。实验采用学习-迁移范式,探究概念训练中样例的呈现方式对类别表征的影响。实验中被试通过不同呈现方式来学习类别知识,在学习3个block之后对其进行测验。实验结果表明:(1)学习单样例和同一类别比较学习的被试在测验阶段的成绩与学习阶段之间没有差异;(2)学习不同类别比较学习的被试在测验阶段的成绩大幅度下降。因此得出结论,在概念训练中,不同类别比较学习导致被试形成类别间信息的表征。     

离身经验的心理学解释与实验证据

有关离身经验的研究有助于当前心理学与认知科学深化对自我及具身认知的认识。进入21世纪以来,通过诱发离身经验之脑与神经科学研究,长期以来笼罩在离身经验上的神秘面纱,在一定程度上得以澄清。当前有关离身经验的科学心理学解释主要包括:诱发离身经验的神经相关物解释、诱发离身经验的身体拥有错觉解释、精神活性物质效用的解释、自发离身经验的特殊性解释。然而,当前的实验心理学与神经科学解释主要侧重于诱发离身经验,而对自发离身经验的解释则有待新的科学框架与理论予以审视。未来的跨学科研究需要继续探索离身经验究竟是一种纯粹的幻觉还是一种实在的知觉,建构更为系统、科学的身体自我意识理论框架来解释离身经验,并利用新兴神经科学技术揭示精神活性物质影响离身经验的、潜在的脑与神经生物学机制。
