父母心理控制与小学生的欺负行为:敌意归因和冷酷无情的作用检验

采用班级整群抽样法选取1847名3~6年级小学生（男生987名;平均年龄10.73±1.16岁）及其家长为被试,采用问卷法考察父母心理控制与小学生欺负行为的关系,同时探讨敌意归因和冷酷无情的中介作用。结果发现：（1）父母心理控制显著正向预测小学生的欺负行为;（2）冷酷无情在父母心理控制与小学生欺负行为间的关系中存在中介作用,敌意归因不发挥中介作用;（3）父母心理控制对小学生欺负行为影响的中介机制不存在显著的性别差异和学段差异。本研究结果表明,冷酷无情是父母心理控制影响小学生欺负行为的重要机制,但敌意归因不是。研究者和实践者应注重对欺负者情感加工能力的关注和干预。     

计算机控制心理学实验过程的计时误差分析

计算机在控制心理学实验过程中,可能引入各种潜在的计时误差,特别在短时呈现各种实验刺激时,有些误差是不应忽略的。本文重点分析屏幕刷新率对实验设计的限制及可能产生的计时误差和解决方法。     

研究生科研角色认同对科研创造力的影响:导师包容性领导、师门差错管理氛围的作用

以来自62个师门的411名全日制在校研究生为被试,采用问卷调查法探讨研究生科研角色认同对科研创造力的影响,并构建多层线性模型,分析导师包容性领导、师门差错管理氛围的调节作用。结果发现：（1）科研角色认同对科研创造力产生显著正向影响;（2）导师包容性领导、师门差错管理氛围在科研角色认同与科研创造力关系中均具有正向调节作用;（3）导师包容性领导对师门差错管理氛围具有显著正向影响,导师包容性领导的调节作用通过师门差错管理氛围的调节作用对研究生科研创造力产生影响。     

错误相关负波（ERN）在精神病理学研究中的应用

错误相关负波（error-related negativity, ERN）是由行为错误诱发的一种脑电波成分,最大峰值在错误反应之后的50ms左右,偶极子源定位于前扣带回（anterior cingulate cortex, ACC）附近。错误加工（error processing）的经典研究范式中出现的ERN成分可能反映了ACC具有错误检测、冲突监控、强化学习、情绪动机等功能。大量研究表明过度的和不足的错误相关脑活动（hyperactive and hypoactive error processing）可能分别与精神病理学的内化性和外化性障碍（internalizing and externalizing disorders）相关联。内化性和外化性障碍的内表型（endophenotype）的研究,还存在许多值得进一步探索的问题。     

Conditions for factor (in)determinacy in factor analysis

The subject of factor indeterminacy has a vast history in factor analysis (Guttman, 1955; Lederman, 1938; Wilson, 1928). It has lead to strong differences in opinion (Steiger, 1979). The current paper gives necessary and sufficient conditions for observability of factors in terms of the parameter matrices and a finite number of variables. Five conditions are given which rigorously define indeterminacy. It is shown that (un)observable factors are (in)determinate. Specifically, the indeterminacy proof by Guttman is extended to Heywood cases. The results are illustrated by two examples and implications for indeterminacy are discussed.     

Empowering and legitimizing the fundamental attribution error: Power and legitimization exacerbate the translation of role‐constrained behaviors into ability differences

Our daily interactions are influenced by the social roles we endorse. People however underestimate these role constraints in their everyday explanation relying on individual dispositions to make sense of behaviors. Two studies investigated whether this bias is exacerbated when role structure is legitimated and when power matches the advantages conferred by the social roles of a quiz game. Legitimacy as well as power increased the tendency for both advantaged (questioner) and disadvantaged (answerer) actors (Study 1) as well as naïve observers of the quiz game (Study 2) to attribute to ability the behaviors elicited by social roles. These results extend previous findings. People are more prone to explain constrained behaviors by differences in ability when role structure is legitimated and when power asymmetry matches role structure. Legitimacy and power may then play an important role in the translation of role constraints into inferences about ability.     

On the Relationships between Sum Score Based Estimation and Joint Maximum Likelihood Estimation

This paper analyzes the sum score based (SSB) formulation of the Rasch model, where items and sum scores of persons are considered as factors in a logit model. After reviewing the evolution leading to the equality between their maximum likelihood estimates, the SSB model is then discussed from the point of view of pseudo-likelihood and of misspecified models. This is then employed to provide new insights into the origin of the known inconsistency of the difficulty parameter estimates in the Rasch model. The main results consist of exact relationships between the estimated standard errors for both models; and, for the ability parameters, an upper bound for the estimated standard errors of the Rasch model in terms of those for the SSB model, which are more easily available.
