Enhanced conflict-driven cognitive control by emotional arousal,not by valence

Emotion is widely agreed to have two dimensions, valence and arousal. Few studies have explored the effect of emotion on conflict adaptation by considering both of these, which could have dissociate influence. The present study aimed to fill the gap as to whether emotional valence and arousal would exert dissociable influence on conflict adaptation. In the experiments, we included positive, neutral, and negative conditions, with comparable arousal between positive and negative conditions. Both positive and negative conditions have higher arousal than neutral ones. In Experiment 1, by using a two-colour-word Flanker task, we found that conflict adaptation was enhanced in both positive and negative contexts compared to a neutral context. Furthermore, this effect still existed when controlling stimulus–response repetitions in Experiment 2, which used a four-colour-word Flanker task. The findings suggest emotional arousal enhances conflict adaptation, regardless of emotional valence. Thus, future studies should consider emotional arousal when studying the effect of emotion on conflict adaptation. Moreover, the unique role of the emotional context in conflict-driven cognitive control is emphasised.     

威廉·詹姆斯与具身认知心理学

威廉·詹姆斯是美国心理学的创始人,被世人称为"美国心理学之父"。他创造了一整套的心理学理论,包括在具身认知兴起的过程中,他也发挥了重要的、不可替代的作用。而具身认知主要指在人们的认知过程中身体发挥着重要的关键作用,亦即认知是人们通过身体的具体体验及其活动方式而产生的。文章主要通过具身认知的兴起来了解在詹姆斯的一整套心理学理论中所包含的具身认知思想以及探究詹姆斯在其中发挥的重大作用。     

Parental Psychological Control and Peer Victimization among Chinese Adolescents: The Effect of Peer Pressure as a Mediator

Peer victimization is a serious problem among children and adolescents. Family and peers are two of the most proximal and influential microsystems for children. The present study examined the influence of parental psychological control and peer pressure on peer victimization. According to social learning theory and attachment theory, parent–child interactions may serve as a model of peer interactions. Therefore, we proposed the hypothesis that peer pressure functioned as a mediator in the association between parental psychological control and peer victimization. We tested this hypothesis in a sample of Chinese adolescents and examined whether this mediation model varied by gender. Participants were 2382 seventh grade students (1166 girls and 1216 boys) in Beijing, China. The results showed that both parental psychological control and peer pressure were positively associated with peer victimization in Chinese adolescents. Additionally, peer pressure partially mediated the effect of psychological control on peer victimization. Furthermore, multi-group comparisons showed that gender differences existed in the mediation model. The direct effect of psychological control on peer victimization was a little larger in boys, whereas the indirect effect was larger in girls. The findings suggest that parental psychological control contributes to peer victimization in non-Western culture as well. These findings also improve our understanding of the underlying mechanisms involved in peer victimization by interrelating family and peer factors.     

The prevalence and predictors of metabolically healthy obesity in obese rural population of China: a cross-sectional study

Till now, no evidence illustrates the prevalence and predictors of metabolically healthy obesity (MHO) in rural areas of China. The objective of this study was, firstly, to examine the prevalence of MHO in rural areas of China, and identify contributing determinants of MHO, Secondly, to comprehensively investigate to the different characteristics between MHO and metabolically unhealthy obesity (MUO). We conducted a population-based cross-sectional study of 2037 participants with obesity in rural Liaoning Province during 2012–2013. Obesity was defined as BMI ≥28 kg/m² and metabolically healthy was defined as not having the metabolic syndrome. The prevalence of MHO was 23.1%, and significantly decreased with advancing age in female group. However there was no significant tendency with advancing age in male group. Independent determinant factors for MHO were age <55 years (odds ratio [OR] 1.659; p = .001), non-current smoking (OR 1.397; p = .038), pre-menopause (OR 1.648; p = .030) and non-hyperuricemia (OR 2.317; p < .001), whereas race, gender, diet score, current drinking, marriage, sleep duration, hyperhomocysteinemia, levels of physical activity, annual income and educational status were not significant contributors. In conclusion, we found that age <55 years, non-current smoking, pre-menopause and non-hyperuricemia were identified as independent determinant factors for MHO in this population.     

社交网站使用对青少年孤独感的影响:链式中介效应分析

为探讨社交网站使用、线上积极反馈、友谊质量和青少年孤独感的关系,采用社交网站使用强度问卷、线上积极反馈问卷、友谊质量量表和孤独感量表对538名中学生进行调查,结果发现:(1)社交网站使用与线上积极反馈和友谊质量都呈显著正相关,而与孤独感显著负相关,线上积极反馈与友谊质量显著正相关,而且两者都与孤独感显著负相关;(2)社交网站使用对孤独感没有直接的预测作用,但能通过两条路径的间接作用影响青少年孤独感:通过线上积极反馈的中介作用;通过线上积极反馈和友谊质量的链式中介作用。研究结果揭示了社交网站使用对青少年孤独感的影响及其作用机制,能为网络时代的青少年降低孤独感提供有益启示。     

6-9岁儿童工作记忆的发展研究

以Baddeley工作记忆模型为基础考察儿童语音环路、视觉空间模板、中央执行的发展及其与复杂广度的关系。225名6-9岁被试完成9个任务,分别测量听力广度及工作记忆三个子系统的功能。发现工作记忆各个子成分的功能在6-9岁期间发展速度不同;中央执行与语音环路和视觉空间模板的联系随年龄增长加强;结构方程模型分析发现中央执行和语音环路功能对儿童听力广度都有显著的直接影响,表明言语复杂广度任务既涉及中央执行功能也涉及语音环路的存贮功能。     

个体证券投资者自我效能感对赌徒谬误的影响

赌徒谬误指当某一独立随机事件发生后,人们倾向认为这一结果再次出现的概率降低。如果一连串的随机事件呈现出一定的趋势,人们倾向于认为随机事件将呈现系统性反转。证券市场中的赌徒谬误指在股票上涨（下跌）序列中做出股价将要下跌（上涨）的判断。本研究探讨股票市场特征（趋势长度及方向）及投资者的人格特征（自我效能感）对赌徒谬误的影响。以83名股票投资者为对象,采用多层线性模型进行分析,结果发现：趋势长度主效应显著,短线情境下赌徒谬误频次更高;趋势方向主效应显著,下跌情境下赌徒谬误频次更高;二者交互作用显著,在短线下跌情境下,赌徒谬误频次更高;投资者的自我效能感对股票趋势长度具有调节作用,高自我效能的投资者在短线情境下更容易出现赌徒谬误。     

高中生不同类型的沉思对抑郁症状发展的中介作用

乔荼波陀与佛教

本论文主要将印度吠檀多派哲学家乔荼波陀的哲学思想与佛教的思想进行比较研究。持“无我论”观点的佛教认为世间一切事物皆无自性实体可言;万物都为因缘和合聚散而生灭。持“有我论”观点的吠檀多派则认为存在着一个精神绝对体（梵我）,它是事物生灭的本源;现象世界随生随灭,而它恒常不灭。本论文认为,乔茶波陀作为印度正统派哲学家,在他的著作《圣教论》中却处处表现出对佛教思想的偏爱,接受了佛教大量的影响,运用唯识宗和空宗的理论来为自己的吠檀多哲学作论证。
