Direct and Indirect Effects of Self-efficacy on Depression: The Mediating Role of Dispositional Optimism

In this study, we aimed to explore the impact of self-efficacy on depression – specifically, to test and verify the mediating role of dispositional optimism between the two variables. Five hundred and thirty-five undergraduates from two universities were recruited and given a Self-Efficacy Questionnaire, Revised Life Orientation Test, and Self-Rating Depression Scale. Results indicated that there are indeed significant relationships among self-efficacy, dispositional optimism, and each identified dimension of depression; structural equation modeling showed that the relationship between self-efficacy and depression is partially mediated by dispositional optimism. To this effect, we concluded that to develop and improve students’ self-efficacy will reduce their levels of depression, which may have implications in college counseling.     

Travelling backwards and forwards in time: culture and gender in the episodic specificity of past and future events

There is considerable evidence that, when recalling past events, Westerners exhibit greater episodic specificity than East Asians and women exhibit greater episodic specificity than men. Yet it is unknown whether the same cultural and gender differences are true for future events. In the present study 209 European American and Chinese young adults were asked to recall past personal events and imagine future personal events occurring in varied time periods (i.e., 1 week, 1 year, 10-15 years). Regardless of time period, European Americans consistently produced more specific details than Chinese for future events than they did for past events, and women produced more specific details than men for both past and future events. These findings provide additional support for the constructive-episodic-simulation hypothesis, and shed new light on the influence of culture and gender on episodic thinking.     

抑郁症患者的服药依从性及影响因素

服药依从性是影响抑郁症患者疗效和复发的重要因素, 然而很多研究发现抑郁症患者的服药依从性较低。与服药依从性有关的概念有服从性、依从性和遵从性。抑郁症服药依从性的影响因素包括疾病与治疗因素、医生相关因素、患者相关因素及文化与环境因素四个方面, 主要从医生和患者两方面进行干预。其评定方法包括主观和客观两种。介绍了研究趋势, 未来应发展服药依从性测量工具, 加强本土化和社会文化因素的研究, 加强共病对抑郁症服药依从性影响的研究, 制定个别化的干预措施, 并加强心理学在抑郁症服药依从性领域的交叉研究。     

内隐联结测验下单纯呈现效应与积极情感的产生

该研究以汉语双字词为刺激材料,以大学生为被试,首先检验了标准的GNAT内隐联结测验范式的有效性,实验一发现,积极名词与正性形容词联结的反应时显著快于与负性形容词联结的反应时.实验二发现,用在标准的单纯重复呈现范式中重复呈现过的中性名词,替换标准GNAT内隐联结测验范式中的积极名词,再次进行标准的GNAT内隐联结测验,观察到了重复呈现的中性名词与正性形容词联结的反应时显著快于与负性形容词联结的反应时,表明被试将重复呈现过的中性刺激与积极刺激联系比与消极刺激的联系更紧密.实验三发现,同样是这些中性名词,当没有被重复呈现时,在GNAT内隐联结测验中与积极形容词和消极形容词的联结的反应时之问差异不显著.研究表明,刺激的重复呈现会导致偏好的产生,使其能够起到积极刺激的作用.该研究认为,刺激的重复呈现,可能是积极情感产生的一个来源.     

交叉影响还是直接影响?工作－家庭冲突的影响机制

考察了带有方向性的两个工作－家庭冲突变量(工作对家庭的冲突、家庭对工作的冲突)对一些常见的结果变量的影响, 检验了交叉影响模型和直接影响模型在中国样本中的适用性。以工作优先行为规范为基础, 在来自中国企业的管理人员的两个样本中发现：家庭对工作的冲突对工作相关结果(工作满意感、留职意向、组织承诺)具有显著的负向影响, 而工作对家庭的冲突则没有显著影响; 工作对家庭的冲突对生活满意感具有显著的负向影响。本文的发现表明交叉影响模型可以作为解释中国管理人员工作－家庭冲突影响机制的理论, 而直接影响模型不能推广到中国样本中。     

文化心理学视野中的思维方式

对东西方思维方式的研究是近十年以来文化心理学领域的一个热点问题。该文以心理学关于思维方式的研究为主线,分析了随着心理学研究的深入,学者们关于思维方式研究的思路转变。重点探讨了文化心理学关于东西方思维对比的研究以及对中国人思维方式的理论和实证分析。这些分析对理解中国人思维方式的影响以及促进东西方文化交流有着重要的理论和现实意义。文章指出了关于思维方式研究的未来方向。     

一类命题逻辑的一般弱框架择类语义

命题逻辑的一般弱框架择类语义是相干邻域语义的变形,其特点是：采用择类运算来刻画逻辑常项;语义运算与逻辑联结词之间有清晰的对应关系,可以从整体上处理一类逻辑,具有普适性。本文将这种语义用于一类B、C、K、W命题逻辑,包括相干逻辑R及其线性片段、直觉主义逻辑及其BCK片段等,并借助典范框架和典范赋值,证明了这些逻辑系统的可靠性和完全性。     

Enriched environment treatment restores impaired hippocampal synaptic plasticity and cognitive deficits induced by prenatal chronic stress

Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown. Experimental animals were Wistar rats. Prenatal stress was evoked by 10 foot shocks (0.8 mA for 1s, 2-3 min apart) in 30 min per day at gestational day 13-19. After weaning at postnatal day 22, experimental offspring were given the enriched environment treatment through all experiments until tested (older than 52 days age). Electrophysiological and Morris water maze testing was performed at 8 weeks of age. The results showed that prenatal stress impaired long-term potentiation (LTP) but facilitated long-term depression (LTD) in the hippocampal CA1 region in the slices. Furthermore, prenatal stress exacerbated the effects of acute stress on hippocampal LTP and LTD, and also impaired spatial learning and memory in the Morris water maze. However, all these deficits induced by prenatal stress were recovered by enriched environment treatment. This work observes a phenomenon that may contribute to the understanding of clinically important interactions among cognitive deficit, prenatal stress and enriched environment treatment. Enriched environment treatment on early postnatal periods may be one potentially important target for therapeutic interventions in preventing the prenatal stress-induced cognitive disorders.

Relativism and Faultless Disagreement

The argument from faultless disagreement employed by the relativist purports to show that contextualism falls short of explaining cases of faultless disagreement. The demonstration is intended to give credence to the relativist semantics of epistemic modality expressions. In this paper we present some cases showing that even though cases of faultless disagreement do reveal some intrinsic features of epistemic modality claims, they do not support the relativist semantics. The sophistication of faultless disagreement goes beyond what the relativist semantics can cope with. We also advance an epistemologically oriented proposal to account for faultless disagreement.
