Body dissatisfaction and body comparison with media images in males and females

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.     

中学师生内隐智力观的发展研究

采用半结构式访谈调查与问卷调查相结合的方法,对中学师生的内隐智力观进行了研究。结果发现：在对聪明男女中学生重要特征的评定中,中学教师对于智力的理解多集中于与认知有关的因素,并且评价所涉及到的方面随被评价对象年龄增长而调整;中学生对于智力的理解多集中于与人际交往有关的因素,并且随着年龄增长表现出更加看重内在特征的趋势;中学教师与中学生的内隐智力观存在一致性,主要表现为他们对聪明特征的评定因被评价对象的年龄和性别不同而变化,也存在一定的差异,具体为教师和学生强调的方面有所不同。     

大学生的理想-现实自我差异及其与抑郁的关系

采用自编的“大学生理想-现实自我差异问卷”和流调中心用抑郁量表,考查了447名1-4年级大学生的理想-现实自我概念差异状况及其与抑郁的关系。结果表明：大学生被试的理想自我概念与现实自我概念存在一定程度的差异;大学生被试的理想-现实自我概念差异在学业、情绪和总分上存在显著的年级差异;家庭经济状况差的大学生被试的理想—现实自我概念差异显著大于家庭经济状况好的被试;大学生的理想-现实自我概念差异与抑郁具有显著的正相关,情绪、人际、家庭自我差异等对抑郁的影响作用较大。     

我国民众对SARS信息的风险认知及心理行为

采用分层抽样的调查方法,对全国17个城市的4231名市民进行了SARS疫情中风险认知特征和心理行为的研究。结果发现：（1）负性信息,包括患病信息和与自身关系密切的信息,更易引起民众的高风险认知; 正性信息,包括治愈信息和政府防范措施的信息,能降低个体风险认知水平。（2）我国民众5月中旬风险认知因素空间位置分析结果表明, SARS病因处于不熟悉和难以控制一端,“愈后对身体的影响和有无传染性”处于不熟悉一端,这是引起民众风险意识的主要因素。（3）结构方程分析结果表明,SARS疫情信息是通过风险认知对个体的应对行为、心理健康产生影响的, 并初步验证了风险评估、心理紧张度、应对行为和心理健康等指标对于危机事件中民众心理行为的预测作用     

理想情感及其影响的跨文化差异

理想情感是人们期望获得的情感状态。情感评估理论认为文化对理想情感的塑造有着重要影响,主要的影响途径有文化体验、文化价值观和社会文化变化。理想情感对个体会产生具有文化特异性的影响,主要会影响个体的偏好及选择行为、混合情绪体验、身心健康和社会认知决策。理想情感研究未来发展可以着眼于4个方向:使用纵向视角研究理想情感,进一步探索理想情感的前因变量,打造适合中国文化的心理健康标准和通过认识理想情感来消除文化隔阂。     

Bridging the Gap: How Supervisors’ Perceptions of Guanxi HRM Practices Influence Subordinates’ Work Engagement

This study aims to provide new insights into the relationship between supervisors' perceptions of guanxi human resource management (HRM) practices and their subordinates' work engagement. We used a three time‐lagged sample from 45 work groups and 205 employees in a state‐owned organisation (Study 1) and cross‐sectional data from 101 work groups and 413 employees in 101 different organisations (Study 2) to test our hypotheses. The results revealed that supervisors' perceptions of guanxi HRM practices were positively related to subordinates' perceptions of guanxi HRM practices, which, in turn, negatively affected subordinates' work engagement. This indirect effect was stronger when group power distance was low or when individual power distance orientation was low.     

压力对大学生抑郁的影响机制:领悟社会支持与应对方式的中介作用

基于心理应激理论、素质-压力三模式以及社会支持主效果模型考察领悟社会支持、积极应对方式和消极应对方式在压力与抑郁关系中的链式中介效应,使用压力量表、领悟社会支持量表、应对方式量表和抑郁量表对抽取的641名大学生进行调查。研究显示:(1)领悟社会支持中介了压力对大学生抑郁的影响;(2)积极应对方式、消极应对方式中介了领悟社会支持对大学生抑郁的影响。因此,领悟社会支持以及应对方式在压力与大学生抑郁之间起链式中介作用。     

启动任务中语言经验对藏-汉双语者主导语的影响

采用语义启动任务及藏语与汉语语义相关词和无关词对,探究语言经验能否改变熟练藏-汉双语者的母语主导优势和双语语义表征方式。结果表明,1)无论启动词为藏语还是汉语,藏-汉双语者对汉语L2目标词的加工速度和正确率均显著好于藏语L1,存在语义启动效应; 而在藏语目标词条件下则未发现显著的语义启动效应; 2)藏语到汉语的语义启动效应大于汉语到藏语的启动效应。结果表明,藏-汉双语者的汉语经验对藏语词的表征有影响,但汉语还不能完全替代母语藏语为主导语,结果在一定程度上支持Kroll的RHM模型和Green的ICM模型。     

Dorsomedial prefrontal cortex 5-HT6 receptors regulate anxiety-like behavior

The dorsomedial prefrontal cortex (dmPFC) plays a very important role in decision-related and anxiety-related information processing. It has enriched 5-HT6 receptors; however, the precise role of dmPFC 5-HT6 receptors in anxiety remains to be fully investigated. In this study, we injected dmPFC with the 5-HT6 receptor agonist EMD 386088 and antagonist SB 271046 using stereotactic technology. 5-HT6 receptor activation in mice increased time spent in the center area on the open-field test, increased exploration of the open arms on the elevated plus maze test, and increased ratio on the social interaction test. 5-HT6 receptor inactivation induced the opposite effects. In brain slices, EMD 386088 decreased both spontaneous inhibitory postsynaptic currents (sIPSC) and spontaneous excitatory postsynaptic currents (sEPSC), while SB 271046 only increased sEPSC. These effects of EMD 386088 and SB 271046 could be reversed by the GABA_A receptor antagonist bicuculline (BMI) and positive allosteric modulator clonazepam (CLZ), respectively. Our results suggest that neurotransmission in the dmPFC by 5-HT6 receptor activation and inhibition may play an important role in anxiety-like behavior, and may provide new insight into the pathological mechanism and potential target of anxiety disorders.     

Effect of achievement motivation on cognitive control adaptations

Previous research addressing motivational effects on cognitive control adaptations primarily manipulated external rewards. In the present study, we examined whether achievement motivation, reflecting intrinsic motivation, modulates cognitive control adaptations. In each of two experiments, students were divided into a high achievement motivation group (HAM; Experiment 1: N?=?36; Experiment 2: N?=?39) and a low achievement motivation group (LAM; Experiment 1: N?=?30; Experiment 2: N?=?39) on the basis of the Achievement Motivation Scale. Cognitive control adaptations were assessed by sequential congruency effects (SCEs) in Flanker tasks. Using a standard Flanker task in Experiment 1 and examining response times, the HAM but not LAM participants showed evidence of cognitive control adaptations. Because SCEs in a standard Flanker task may reflect lower-level, bottom-up processes rather than cognitive control adaptations, we used an adapted version of the Flanker task in Experiment 2 that controlled for the potential influence of such processes. Experiment 2 again revealed evidence of SCEs in the HAM but not LAM participants. These results suggest that cognitive control adaptions may be modulated by achievement motivation. Such potential modulation could be taken into account when evaluating results of previous and future fundamental and applied studies on cognitive control adaptations.
