The Downsides of Extreme Conscientiousness for Psychological Well‐being: The Role of Obsessive Compulsive Tendencies

Although conscientiousness exhibits positive relations with psychological well‐being, theoretical and empirical work suggests individuals can be too conscientious, resulting in obsessive‐compulsiveness, and therein less positive individual outcomes. However, the potential for curvilinearity between conscientiousness and well‐being has been underexplored. We measured 912 subjects on facets of conscientiousness, obsessive‐compulsive personality, and well‐being variables (life satisfaction, job satisfaction, self‐esteem, positive affect, negative affect, work stress). Methods of scoring included traditional sum‐scoring, traditional item response theory (IRT), and a relatively new IRT approach. Structural models were estimated to evaluate curvilinearity. Results confirmed the curvilinear relationship between conscientiousness and well‐being, and demonstrated that differential facet‐level relationships underlie weaker curvilinearity at the general trait level. Consistency was found in the strength of relation between conscientiousness facets with their obsessive‐compulsive variants and their contribution to decreased well‐being. The most common association was that higher standing on conscientiousness facets was positively related to negative affect. Findings support the idea that extreme standing on facets of conscientiousness more strongly linked to their obsessive‐compulsive variants contributed to lower well‐being, highlighting the importance of considering alternative functional representations of the relationship between personality and other constructs. Future work should seek to further clarify the link between conscientiousness and negative affect.     

Depletion from Self‐Regulation: A Resource‐based Account of the Effect of Value Incongruence

Value incongruence between employees and organizations has been identified as a negative work condition. An attitude‐based account suggests that value incongruence gives rise to negative attitudes toward organizations and thus causes low performance. To complement this mechanism, we propose a resource‐based account based on ego‐depletion theory, which suggests that value incongruence consumes an individual's regulatory resources and leads to low work performance. In support of this view, results from 2 survey studies and a vignette experiment reveal that value incongruence is positively associated with ego depletion, which in turn is negatively related to work performance. The mediation effect of ego depletion is independent of the attitude‐based mechanism as represented by job satisfaction and affective commitment. Consistent with the affective consistency perspective, the relationship between value incongruence and ego depletion is stronger among employees high in positive affectivity and weaker among employees high in negative affectivity. The corresponding moderated mediation analysis shows that the indirect effects of value incongruence on work performance through ego depletion vary as a function of positive and negative affectivity. This investigation unravels the self‐regulatory consequence of value incongruence and shows that the resource‐based mechanism of value incongruence operates differentially as a function of dispositional affectivity.     

加工水平及词对类型在新异联系形成中的作用

该研究采用过程分离方法和知觉辨认方法探讨不同加工水平和词对类型在新异联系形成中的作用。结果表明,深加工是形成非相关词对间联想启动的条件之一。另外,具体词对的联想启动没有表现出加工水平效应,出现了内隐和外显记忆的分离现象,提示不同的词对类型与加工水平间存在着交互作用,当联系程度较紧时,并不一定需要语义加工,而联系程度不紧时,语义加工则是必要的。     

一日龄小鸡的不同记忆阶段中Jun样蛋白在脑内HV和LPO的表达

以一日龄小鸡为研究对象,采用一次性动回避反应试验和免疫组织化学结合的方法,选择六个时间点对Ｊｕｎ样蛋白在小鸡左右侧脑内ＨＶ和ＬＰＯ两部位的表进行了探讨。     

威胁对创造力的影响：认知与情绪双加工路径

威胁对创造力的影响颇具热点性与争议性, 总体来看, 当前存在威胁对创造力的阻碍、促进以及两者间呈倒U型关系三种观点。但三种观点分歧的原因与内在机制尚不清楚。本文从认知与情绪角度对相关研究进行了梳理, 认为以上分歧来自于威胁等级的不同, 创造力机制的差异及相关的中介/调节变量。未来研究可从认知与情绪干预的角度, 系统验证观点分歧的原因, 深入分析威胁与创造力的认知神经和基因等内在机制。     

外来务工女性刻板印象威胁的应对策略与认同管理

为了探讨外来务工女性群体刻板印象威胁的应对策略和认同管理,从天津市WX社区通过滚雪球抽样方法选取124名外来务工女性作为被试,采用问卷调查的形式,测查了外来务工女性群体刻板印象应对策略和认同管理模式,尤其考察了认同基线水平、认同融合、否定策略和榜样策略对于应对和认同管理的有效性。结果表明：（1）外来务工女性群体具有双重认同趋势;具有较高城市认同融合的外来务工女性群体具有显著的认同维护倾向;（2）不同印象管理水平的外来务工女性对否定策略的使用差异性很小,反而是刻板印象威胁的长期性和暴露性是引发否定策略的重要因素;（3）角色榜样成功的应得性对外来务工女性城市认同感的提高具有积极效应;（4）城市务工年数和收入成为这一群体城市认同的主要影响因素。     

光照对小鸡脑内神经细胞粘附分子表达的影响

胚胎发育晚期光照条件的不同,对小鸡后天的学习记忆能力有显著的影响,暗孵化小鸡表现出明显的长时记忆障碍。实验利用免疫组化的方法,分别对光孵化、正常孵化和暗孵化条件下,胚胎发育的第17、18、19、20、21天,小鸡脑内上纹体腹核(HV)中神经细胞粘附分子(NCAMs)的表达进行了观察。结果表明：暗孵化条件下孵出的小鸡,在一次性被动回避学习中,记忆保持水平显著低于光孵化组和正常孵化组;在胚胎发育的第20天NCAM的表达,在光孵化组和正常孵化组中显著增高,到胚胎发育的第21天,这种升高在正常孵化组中显著下降;而暗孵化组在整个观察过程中,NCAM表达水平一直非常低。这一结果提示,不同光照条件在孵化过程中,对NCAM表达的影响,参与了光照对小鸡后天学习记忆行为改变的过程。     

神经细胞粘附分子的唾液酸化作用对小鸡记忆的影响

神经细胞粘附分子的多聚唾液酸化不仅影响发育阶段神经元之间的相互作用,而且在学习记忆过程中也起着重要的作用。实验中的特异切割神经细胞粘附分子和多聚唾液酸之间α－２,８键在内神经氨酸苷酶ｅｎｄｏｎｅｕｒａｍｉｎｉｄａｓｅ ＮＥ定位注射到一日龄小鸡脑ＩＭＨＶ内,此酶明显破坏小鸡对一次性被动回避反应的记忆保持。这种破坏作用与酶的剂量有关,小于４μｇ的内神经氨酸苷酶对小鸡的记忆没有明显的影响。对胚胎第２０天
