Consistent Differential Discrimination Model Estimation

A novel factor-analytic model—the differential discrimination model—for assessing individual differences in scale use has been recently introduced, together with a three-stage estimation approach for model fitting. Unfortunately, the second-stage estimator and, as a consequence, the third-stage estimator of this procedure are not consistent. In this article we show that (a) the differential discrimination model can be expressed in a structural equation model framework, and (b) consistent and simultaneous estimation of all model parameters can be achieved using standard SEM software.     

PTSD易感性人格特质、工作记忆能力和创伤期间认知加工对模拟创伤闪回的影响

基于模拟创伤研究范式, 采用道路交通事故影片对159名健康大学生进行模拟创伤, 考察PTSD易感性人格特质(特质焦虑、特质分离和神经质)、工作记忆能力(注意控制和工作记忆容量)和创伤期间认知加工(数据驱动加工和概念加工)对模拟创伤后不同时段闪回的影响。运用结构方程模型分析数据, 结果发现：(1)数据驱动加工正向预测不同时段闪回(即时闪回、一周闪回和触发闪回)的数量、生动性、痛苦度以及一周侵入频率; (2)神经质正向预测触发闪回痛苦度, 注意控制和工作记忆容量负向预测一周侵入频率; (3)概念加工在注意控制与即时闪回痛苦度之间起中介作用。研究结果提示：数据驱动加工是创伤后不同时段闪回的主要影响因素; 概念加工主要作用于早期急性应激反应, 注意控制是其保护因素; 神经质和工作记忆能力对闪回具有较长期的影响, 且工作记忆能力具有一定的保护作用。     

童年期不良经历对中学生良心的影响：特质自我控制和自我损耗的链式中介作用

为探讨童年期不良经历对中学生良心的影响及作用机制,基于生物生态学理论和自我控制资源模型,采用整群取样法抽取湖南省7所城市7所中学初一到高三学生共3648名,使用童年期不良经历问卷、青少年良心问卷、特质自我控制量表和自我调节疲劳量表进行问卷调查。结果发现:(1)童年期不良经历负向预测中学生良心;(2)特质自我控制和自我损耗在童年期不良经历和中学生良心间起部分中介作用;(3)特质自我控制和自我损耗在童年期不良经历和中学生良心间起链式中介作用。研究结果表明,童年期不良经历不仅是影响中学生良心的重要外部因素,而且还会通过影响特质自我控制和经由自我损耗对中学生良心产生间接作用;减少和避免童年期不良经历对中学生心理的冲击,提升其特质自我控制水平,降低其自我损耗,是预防中学生良心失守和提升良心水平的重要途径。     

Could sex difference in color preference and its personality correlates fit into social theories? Let Chinese university students tell you

The unclear picture of the sex difference in color preference might result from personality variations. We invited 359 Chinese university students (166 men and 193 women) to undergo a color preference test and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), a five-factor model test. Depressive trends were measured by the Plutchik-van Praag Depression Inventory (PVP). There was no significant difference between men and women regarding either ZKPQ or PVP scale scores. However, men preferred blue and green significantly more, and their preference order of yellow was negatively correlated with ZKPQ Sociability. Women preferred purple, pink and white significantly more, their preference order of gray was positively correlated with Neuroticism-Anxiety, and the order of orange negatively with Aggression-Hostility. Our results suggest that, partly from a biological layout, men as hunters and women as gatherers prefer some different colors on the one hand, but from a social structural layout, they might try to adjust some personality traits by preferring other colors on the other, in order to attain a sex-equality but polychromatic world.     

基于候选人面孔的特质推理与投票决策

在竞选情境中, 基于政治候选人面孔的能力或热情特质推理可以预测选举结果。面孔吸引力、面孔成熟度、面部表情和面孔熟悉度等因素对基于面孔的特质推理预测竞选结果起着重要作用。近年来, 研究者已经由基于面孔预测结果的行为研究逐步扩展到神经机制的研究上, 采用fMRI技术发现当被试对候选人面孔做负性特质判断和投票时, 杏仁核、岛叶、腹前侧扣带回等脑区会被激活, 而获胜候选人的照片并不会引起脑区的激活。研究者从认知取向和进化适应角度解释了人们为什么会根据面孔中的特质推理进行预测。以往研究在实验材料、研究内容等方面仍有不足, 这也指明了未来的研究方向。     

An application of belief‐importance theory with reference to trait emotional intelligence,mood, and somatic complaints

Petrides, K.V. (2011). An application of belief‐importance theory with reference to trait emotional intelligence, mood, and somatic complaints. Scandinavian Journal of Psychology 52, 161–167. This article describes the basic principles of belief‐importance (belimp) theory and tests them in two empirical studies. Belimp theory hypothesizes that personality traits confer a propensity to perceive convergences and divergences between our belief that we can attain goals and the importance that we place on these goals. Belief and importance are conceptualized as two coordinates, together defining the belimp plane. Four distinct quadrants can be identified within the belimp plane (Hubris, Motivation, Depression and Apathy), broadly corresponding to the personality dimensions of trait emotional intelligence, conscientiousness, neuroticism and introversion. Study 1 (N = 365) defines the four quadrants in relation to goals about financial security and shows that they score differently on trait emotional intelligence, mood and somatic complaints. Study 2 (N = 230) defines the quadrants in relation to goals about appearance and, separately, in relation to goals about popularity, and replicates the findings of the first study. Strategies and requirements for testing belimp theory are presented, as are a number of theoretical and practical advantages that it can potentially offer.     

Application of signature strengths at work: A dual-level analysis

ABSTRACT

Each individual possesses character strengths, the most significant of which are classified as signature strengths. With a sample of 164 individuals who were employed at least part-time in a variety of industries, we examined application of signature strengths and well-being both between-persons (global) and within-persons (daily). Global application of signature strengths was associated with global job satisfaction and strain; however, no significant mediation effects on intent to turnover were found. We also found that daily variations in application of signature strengths were related to daily job satisfaction and strain. Common method bias associated with trait positive and negative affect differed by level of analysis: At the between-person (global) level, trait affect produced substantial inflation of estimates, but at the within-person (daily) level, inflation was negligible. The results suggest the importance of daily opportunities to apply signature strengths and of accounting for variance attributable to trait affect in between-person analyses.
