相对剥夺感与大学生社交焦虑的关系：一个有调节的中介模型

采用问卷法对湖北省674名大学生进行调查,探讨了相对剥夺感影响社交焦虑的路径,考察了核心自我评价的中介作用和自我关注的调节作用。结果发现：(1)相对剥夺感可以正向预测大学生社交焦虑;(2)核心自我评价在大学生相对剥夺感与社交焦虑之间起中介作用;(3)自我关注调节了核心自我评价中介效应的后半段路径,即随着自我关注程度提高,核心自我评价对社交焦虑的预测作用增强。     

大学生自尊与社会适应的关系:积极核心图式与同伴依恋的链式中介效应分析

采用自尊量表、简明核心图式量表、同伴依恋量表和中国大学生适应量表调查华中三省5所大学大一至大三年级共459名大学生,运用偏差校正的百分位Bootstrap方法探索大学生积极核心图式和同伴依恋在自尊和社会适应之间的链式中介作用。结果发现：（1）大学生自尊、积极核心图式、同伴依恋与社会适应两两之间均呈显著正相关;（2）大学生自尊对社会适应的直接效应和间接效应均显著。间接效应包括了三条路径：通过积极核心图式的中介作用、通过同伴依恋的中介作用以及通过积极核心图式-同伴依恋的链式中介作用。这一结论有助于理解自尊对社会适应的作用机制,为未来大学生社会适应能力的提升提供建议。     

Becoming More Conscientious or More Open to Experience? Effects of a Two-Week Smartphone-Based Intervention for Personality Change

Research indicates that it might be possible to change personality traits through intervention, but this clinical research has primarily focused on changing neuroticism. To date, there are no established, proven techniques for changing other domains of personality, such as conscientiousness and openness. This research examined the effects of a two-week smartphone-based intervention to either change one facet of conscientiousness (i.e. self-discipline) or one facet of openness to experience (i.e. openness to action). Two intervention studies (total N = 255) with two active intervention groups for mutual comparisons were conducted. Results of self-reports and observer reports showed that people who wanted to become more self-disciplined were less self-disciplined at pretest. Similarly, people who wanted to become more open to action were less open to action at pretest. The results showed that people who chose the self-discipline intervention showed greater increases in self-discipline, and people who chose the openness to action intervention showed greater increases in openness to action compared with the other group. Changes were maintained until follow-up two and six weeks after the end of the intervention. Future work is needed to examine whether these personality changes are enduring or reflect temporary accentuation as a result of participation in the intervention. © 2020 European Association of Personality Psychology     

教学查房规范化的基本理解与思考

教学查房是以培养医学生为主要目的的临床教学活动,它与医疗查房有着重要区别。三级医师教学查房是我国医学教育的基本模式,目前存在诸多问题,如何使教学查房规范化是大家面临的共同困惑。在临床教学实践中,教学查房规范化是现代化医学教育的迫切要求。     

Some Results on Mean Square Error for Factor Score Prediction

For the confirmatory factor model a series of inequalities is given with respect to the mean square error (MSE) of three main factor score predictors. The eigenvalues of these MSE matrices are a monotonic function of the eigenvalues of the matrix Γ _p = Φ ^1/2 Λ _p ′Ψ _p ⁻¹ Λ _p Φ ^1/2. This matrix increases with the number of observable variables p. A necessary and sufficient condition for mean square convergence of predictors is divergence of the smallest eigenvalue of Γ _p or, equivalently, divergence of signal-to-noise (Schneeweiss & Mathes, 1995). The same condition is necessary and sufficient for convergence to zero of the positive definite MSE differences of factor predictors, convergence to zero of the distance between factor predictors, and convergence to the unit value of the relative efficiencies of predictors. Various illustrations and examples of the convergence are given as well as explicit recommendations on the problem of choosing between the three main factor score predictors. The author is obliged to Maarten Speekenbrink and Peter van Rijn for their assistance with plotting the figures. In addition, I am obliged to the referees for their stimulating remarks.     

Epistemic presentism

Commonsense functionalism is taken to entail a version of the extended mind thesis, according to which one’s dispositional beliefs may be partly constituted by artifacts. As several opponents of the extended mind thesis have objected, claiming so can generate a cognitive/knowledge bloat, according to which we may count as knowing the contents of trusted websites, even before looking them up (!). One way to retain commonsense functionalism, but avoid the ensuing “cognitive/knowledge bloat” worry is to introduce epistemic presentism—the view that there are no dispositional beliefs and that we can only believe, and thereby know, things in the present. Independently of the above problem, epistemic presentism can be further motivated by shedding light on two central epistemological questions: (1) how to understand the distinction between doxastic and propositional justification and (2) how to interpret the closure principle. The view also aligns with strong intuitions about what we may take ourselves to know, what the relation between action and belief is, and what may count as part of our minds.     

The role of social identity processes in mass emergency behaviour: An integrative review

This review provides a new integration of recent research that has formed the basis of a social identity explanation of supportive collective behaviour among survivors in emergencies and disasters. I describe a model in which a sense of common fate is the source of an emergent shared social identity among survivors, which in turn provides the motivation to give social support to others affected. In addition, by drawing on the concept of relational transformation in psychological crowds, I show how an emergent shared social identity can engender a range of further behavioural and cognitive consequences that contribute to collective self-organisation in emergencies, including expected support, coordination of behaviour, and collective efficacy. It will be argued that the model can been applied to explaining how potentially dangerous crowd events avoid disaster: shared social identity operates as the basis of spontaneous self-organisation in these cases, as in many emergencies and disasters.     

社交网站成瘾与青少年抑郁的关系:认知负载和核心自我评价的中介作用

为探讨社交网站成瘾对青少年抑郁的影响及其作用机制,在素质-压力模型的视角下,采用社交网站成瘾量表、认知负载量表、核心自我评价量表和流调中心抑郁量表,对武汉市三所全日制中学886名初中生进行调查。结果表明:(1)社交网站成瘾、认知负载、核心自我评价和抑郁两两间存在显著的相关,且社交网站成瘾对抑郁具有显著的正向预测作用;(2)认知负载和核心自我评价能在社交网站成瘾与抑郁的关系中起完全中介作用。具体而言,社交网站成瘾通过三条路径影响抑郁:一是认知负载的单独中介作用;二是核心自我评价的单独中介作用;三是认知负载-核心自我评价的链式中介作用。本研究揭示了社交网站成瘾与抑郁的关系及其作用机制,拓展了社交网站成瘾对个体心理社会适应的研究。     

大学生手机成瘾与学习投入的关系:自我控制的中介作用和核心自我评价的调节作用

为考察手机成瘾、自我控制、核心自我评价和学习投入之间的关系,本研究采用手机成瘾量表、自我控制双系统量表、核心自我评价量表以及学习投入量表对628名大学生进行问卷调查。结果显示：（1）手机成瘾可以负向预测大学生学习投入;（2）控制系统和冲动系统在手机成瘾与学习投入的关系中起并行中介作用;（3）手机成瘾对学习投入的直接预测作用受到核心自我评价的调节。研究结果揭示了手机成瘾对学习投入的作用机制,拓展了核心自我评价的研究视角,对于学习投入的干预工作有一定实践意义。     

“打”出来的手机成瘾？父母粗暴养育对青少年智能手机成瘾的作用

对湖北省两所中学3219名初一至初三年级学生进行问卷调查,建立结构方程模型考察父母粗暴养育、核心自我评价、友谊质量和青少年智能手机成瘾的关系。结果发现：（1）核心自我评价在父母粗暴养育和青少年智能手机成瘾之间起部分中介作用,即父母粗暴养育既对青少年智能手机成瘾产生直接影响,也通过核心自我评价对青少年智能手机成瘾产生间接影响;（2）父母粗暴养育和核心自我评价的关系（中介作用的前半段路径）受到友谊质量的调节,即在高友谊质量和低友谊质量条件下,随着粗暴养育程度的增加,青少年核心自我评价均显著下降,但在高友谊质量的条件下,下降的程度更高。研究结果有助于揭示父母粗暴养育对青少年智能手机成瘾的影响及其作用机制,为预防和干预青少年智能手机成瘾带来一些重要的启示。
