条件性恐惧记忆提取消退干预范式

提取消退(retrieval-extinction, Ret+Ext)范式是基于记忆再巩固理论, 利用消退训练(extinction, Ext)能改变条件刺激(conditioned stimulus, CS)的恐惧效价特点, 把消退训练应用到再巩固时间窗内来改写(rewrite)恐惧记忆, 消除恐惧反应。提取消退范式是对传统暴露疗法和药物治疗的创新和拓展, 不仅为创伤性记忆的治疗提供一种非侵入性的技术, 而且也为改写人类记忆、积极心理学探索人类幸福感方面开辟了一种全新的理论视角。     

团队异质性的平衡性对团队创造力的影响

团队异质性的平衡性是指团队中异质性属性的相对分布情况, 是一个从不平衡到平衡的连续谱概念。作为对团队构成维度的补充, 本研究探究其如何通过团队信息深化施加影响于团队创造力。通过对浙江理工大学451名学生的团队实验研究, 得出结论认为：团队知识异质性的平衡性能够积极影响团队创造力, 且团队信息深化在这一过程中起中介作用, 性别异质性的平衡性与团队创造力之间的关系不显著。这一研究结果将有助于打开团队构成和团队创造力研究的新局面。     

定序变量回归模型在心理数据分析中的应用

定序变量在心理现象和心理数据中随处可见, 采用综合的定序变量回归分析模型可以对“镜像模式”和“漏斗模型”的心理现象做出合理的解释和预测。首先通过非参数检验对影响因素进行初步降维, 其次用Probit定序回归对降维后的影响因素贡献率进行判别, 从而进一步筛选具有显著性判断水平的有效指标, 最后用Logistic回归模型对某种特定的心理现象发生与否进行信息量足够大的解释和预测。大学毕业生工作生活质量满意度的预测对这种综合定序变量回归分析模型的实例拟合, 证实了综合定序变量回归分析模型在心理现象和心理数据分析中的应用价值。     

青少年社会适应行为与大五人格的关系

以广州市556名中学生为被试,采用自编<青少年社会适应行为量表>和<大五人格简式量表(NEO-FFI)>,探讨青少年社会适应行为与大五人格之间的关系.结果发现:(1)青少年社会适应行为的总体水平比较好.(2)青少年在良好社会适应行为总均分上不存在性别和年级上的差异,在不良社会适应行为总均分上存在显著的性别差异和年级差异.女生得分显著高于男生,高一学生得分显著高于初二.但二者的交互作用不显著.(3)严谨性、外倾性、宜人性、开放性与大部分良好社会适应行为存在显著正相关,神经质与大部分良好社会适应行为存在显著负相关;严谨性、外倾性、宜人性与不良社会适应行为存在显著负相关,神经质与不良社会适应行为存在显著正相关,开放性与不良社会适应行为相关不显著.(4)进入每个预测良好社会适应行为回归方程的人格维度分别为2-4个,能够解释5.1%-40.5%的变异,严谨性是主要和稳定的预测因素.(5)进入每个预测不良社会适应行为回归方程的人格维度分别为2-3个.能够解释9.3%-16.1%的变异,严谨性、宜人性是主要和稳定的预测因素.     

Exploring the Effects of Job Autonomy on Engagement and Creativity: The Moderating Role of Performance Pressure and Learning Goal Orientation

Purpose

The 21st century work environment calls for team members to be more engaged in their work and exhibit more creativity in completing their job tasks. The purpose of this study was to examine whether team performance pressure and individual goal orientation would moderate the relationships between individual autonomy in teams and individual engagement and creativity.

Design/Methodology/Approach

A sample consisting of 209 team members and 45 team managers from 45 work teams in 14 companies completed survey measures. To test our hypotheses, we used multilevel modeling with random intercepts and slopes because the individual-level data were nested within the team-level data.

Findings

Hierarchical linear modeling showed that team-level performance pressure attenuated the positive relations between job autonomy and three dimensions of engagement. There were also 3-way interactions between job autonomy, psychological performance pressure, and learning goal orientation in predicting three dimensions of engagement and creativity.

Implications

This study highlights the importance of exploring the moderating effect of team-level task characteristics and individual differences on the relationships between job autonomy and individual engagement and creativity. Organizations need to carefully consider both individual learning goals and performance pressure when empowering team members with job autonomy.

Originality/Value

This is one of the first studies to explore the association between individual job autonomy in teams and individual outcomes in a contingency model. We first introduced team performance pressure as a moderator of job autonomy and examined the 3-way interaction effects of performance pressure, individual job autonomy, and learning goal orientation.

White selves: conceptualizing and measuring a dominant-group identity

This article addresses the nature and measurement of White racial identity. White identification is conceptualized as an automatic association between the self and the White ingroup; this association is fostered through social exposure to non-Whites and serves to link self- and ingroup evaluations. Four studies validated a measure of White identification against criteria derived from this model. In Study 1, the White Identity Centrality Implicit Association Test (WICIAT) predicted response latencies in a task gauging self-ingroup merging. In Study 2, the WICIAT correlated with census data tapping exposure to non-Whites. In Studies 3 and 4, the WICIAT predicted phenomena associated with the linking of self- and ingroup evaluations: identity-related biases in intergroup categorization (Study 3) and self-evaluative emotional reactions to ingroup transgressions (Study 4). Together, the findings shed light on the antecedents and consequences of White identity, an often-neglected individual difference construct.     

科技侵扰与恋爱关系满意度:有调节的中介效应

采用问卷法对454名处于亲密恋爱关系中的未婚个体进行调查,考察了沟通质量在科技侵扰与亲密关系满意度之间的中介效应,及信任对这一中介过程的调节效应。结果表明：(1)科技侵扰对亲密关系满意度具有显著负向预测作用;(2)沟通质量在科技侵扰与亲密关系满意度之间起中介作用;(3)科技侵扰通过沟通质量对亲密关系满意度的中介受到信任的调节,具体来说,个体对伴侣信任水平较高时,将减弱沟通质量变差对亲密关系满意度的破坏作用。本研究在新的时代背景下探究智能手机使用在亲密互动中的影响及其中的机制和边界条件。研究结果提示,科技侵扰可以通过破坏沟通质量影响恋爱个体的亲密关系满意度,且在此过程中信任可以缓冲沟通质量变差对亲密关系的影响。     

中国青少年父母教养方式与自杀意念的元分析

如何降低自杀意念是研究者共同面临的问题,其中家庭因素近些年得到了越来越多的关注。本研究采用元分析的方法考察中国青少年父母教养方式与自杀意念的关系及其影响因素,纳入了符合标准的文献22篇,包括158个效应量,总样本量为16980人。结果发现,父母积极教养方式与自杀意念呈显著负相关,父母消极教养方式与自杀意念呈显著正相关。年龄阶段、自杀意念测量工具能够显著调节父母教养方式与自杀意念的关系,独生子女比例能够调节父母消极教养方式与自杀意念的关系。上述结果表明,父母教养方式能够显著影响自杀意念,家长应采用情感温暖、理解等积极教养方式,而非拒绝、过度干涉等消极教养方式。
