社会认知中归纳推论－演绎推论的不对称性现象

在社会知觉中,人们会较多的根据个体的行为表现推论其所具有的人格特质（归纳推论）,较少根据人格特质来推论个体的行为表现（演绎推论）,Maass将这一现象命名为归纳推论－演绎推论的不对称性,并在西方文化下验证了这一现象。刻板印象在这一不对称性现象中起着调节作用,行为信息与刻板印象是否一致影响了归纳推论,对与刻板印象一致的信息更易做出归纳推论,而对演绎推论没有影响。在不同的文化背景下,归纳推论－演绎推论的不对称性表现存在差异,东方文化下的个体对两种推论过程没有表现出明显的倾向性。本文介绍了这一现象的表现,并总结了产生这一社会现象的内在原因及相关的研究进展。     

Information matrix estimation procedures for cognitive diagnostic models

Two new methods to estimate the asymptotic covariance matrix for marginal maximum likelihood estimation of cognitive diagnosis models (CDMs), the inverse of the observed information matrix and the sandwich-type estimator, are introduced. Unlike several previous covariance matrix estimators, the new methods take into account both the item and structural parameters. The relationships between the observed information matrix, the empirical cross-product information matrix, the sandwich-type covariance matrix and the two approaches proposed by de la Torre (2009, J. Educ. Behav. Stat., 34, 115) are discussed. Simulation results show that, for a correctly specified CDM and Q-matrix or with a slightly misspecified probability model, the observed information matrix and the sandwich-type covariance matrix exhibit good performance with respect to providing consistent standard errors of item parameter estimates. However, with substantial model misspecification only the sandwich-type covariance matrix exhibits robust performance.     

Hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading.     

移动购物更快吗?决策场景与思维模式的相容性

既有文献对消费者延迟选择影响因素的研究, 主要集中于决策复杂度、决策者特质或情绪, 少有对决策场景进行深入探讨。互联网购物时代, PC端与手机端已成为重要的消费场景。针对手机端是否会加快消费者决策过程的问题目前也存在不一致的结论。本文引入决策双系统理论, 力图解释以往看似冲突的结论。消费者的购买决策模式, 不仅会受到决策任务(产品价格)的影响, 还会受到决策场景(购买终端)影响。当场景与决策任务使消费者启动的思维模式相一致时, 会提升决策流畅度, 降低延迟选择。本文发现, 移动端(PC端)与低(高)价格产品更容易激发相容的经验性(理性)思维, 降低延迟选择倾向。反之, 则会同时启动两种相左的决策思维, 增加延迟选择倾向。本文从场景启动与价格启动视角, 将以往消费者单一的决策思维模式, 拓展到多因素启动的思维模式相容性问题; 同时本文通过探究延迟选择问题, 对价格策略与场景化营销带来启示。     

Influence of in utero exposure to maternal depression and natural disaster-related stress on infant temperament at 6 months: The children of Superstorm Sandy

This study examined the effects of in utero exposure to maternal depression and Superstorm Sandy, a hurricane that hit metropolitan New York in 2012, on infant temperament at 6 months. Temperament was assessed using the Infant Behavior Questionnaire-Revised. Maternal depression was measured by the Edinburgh Postnatal Depression Scale. The main effects and the interaction of maternal depression and Sandy exposure on infant temperament were examined using a multivariable generalized linear model. Results show that prenatal maternal depression was associated with lower emotion regulation and greater distress. Stratification and interaction analyses suggested that the adverse effects of prenatal maternal depression on problematic temperament were amplified by in utero Sandy exposure. This study underscores the importance of providing prenatal screening and treatment for maternal depression during pregnancy while also identifying high-risk families who may have suffered from disaster-related traumas to provide necessary services. As the frequency of natural disasters may increase due to climate change, it is important to understand the consequences of in utero stress on child development and to formulate plans for early identification.     

累并快乐着：服务型领导的收益与代价——基于工作-家庭资源模型视角

服务型领导被以往大量研究证实能够对下属产生积极的影响效果。然而, 我们对服务型领导如何影响领导者自己还知之甚少。基于此, 文章根据工作-家庭资源模型, 探讨了服务型领导的收益与代价。采用经验抽样法, 对广州市76名企业单位中的主管进行为期5天的日记研究, 并运用多层线性模型进行数据分析。结果表明：主管每日从事服务型领导行为既可以产生更多的积极情绪, 从而改善工作-家庭关系, 又可能会引发资源损耗, 从而恶化了工作-家庭关系。主管感知的组织支持是服务型领导行为双刃剑效应的“门阀”, 当主管感知到高的组织支持时, 从事服务型领导行为会带来更多的积极情绪, 而当主管感知到低的组织支持时, 从事服务型领导行为可能更容易增加资源损耗。以上结果能拓宽我们对服务型领导影响效果的认识, 并为如何干预服务型领导行为提供一些新的启发。     

Reverse evolution in nanoscale Cu-rich precipitates of an aged Fe–Cu alloy under electropulsing

Nanoscale Cu-rich precipitates (CRPs) are one of the most important microstructural nano-features responsible for embrittlement and hardening of reactor pressure vessels (RPVs), which threaten the safe operation of nuclear power plants (NPPs) and hinder the lifetime extension of nuclear reactors. A thermally aged Fe-1.1 wt.%Cu alloy, which is used to simulate embrittlement of the irradiated RPV steels, was treated by electropulsing with various parameters. The effect of electropulsing on nanoscale CRPs was investigated by using transmission electron microscopy (TEM). Compared to the traditional heat treatment, the electropulsing treatment (EPT) can accelerate the dissolution of CRPs in an aged Fe-Cu alloy on account of the higher atomic drift flux and the additional Gibbs free energy induced by electropulsing. More importantly, EPT is likely to be a new way of eliminating irradiation-induced Cu-rich precipitates.     

生活事件对初中生抑郁的影响:自尊和反刍思维的链式中介作用

为了探讨生活事件、自尊、反刍思维和初中生抑郁之间的关系,研究采用青少年生活事件量表、自尊量表、反刍思维量表和儿童抑郁量表对684名初中生进行调查。结果显示：（1）生活事件与初中生抑郁呈显著正相关;（2）自尊和反刍思维在生活事件和初中生抑郁间起链式中介作用。生活事件不仅是触发初中生抑郁的重要外部因素,而且生活事件还会通过影响自尊和经由反刍思维对初中生抑郁产生间接作用。因此,减少和避免生活事件对初中生心理的冲击,增强其自尊水平,调整其负性认知方式是改善和预防初中生抑郁的重要途径。     

你和上司合拍吗?组织中的上下级匹配

上下级匹配, 作为影响领导-下属良性互动的关键因素, 近几年逐渐成为组织管理研究中的前沿话题。上下级匹配是指领导和下属在心理或行为特征方面的契合度, 包括一致性匹配和互补性匹配两种类型, 其测量方式也涉及直接测量与间接测量。从现有文献来看, 研究者主要考察了领导-下属在人格特质、社会认知、心理状态、工作行为和关系因素等方面的匹配效应, 涉及心理过程和互动过程两大中介机制, 个体因素和情境因素两大调节机制。未来研究可以关注传统性、面子意识等本土心理特征的匹配效应, 或者对现有的中介、调节机制进行拓展。
