知觉模糊度影响学习的延迟效应

基于迁移适当加工理论,采用连续识别任务范式,通过操纵字词和图片的模糊度来考察知觉模糊非流畅的延迟效应。结果发现：（1）模糊不流畅的材料学习判断值更低;（2） 知觉模糊程度对即时的再认成绩没有影响,但在延迟再认测试中流畅性较低的模糊材料成绩更好。该结果表明实验操纵方式所引发的编码过程和记忆测试所需的检索过程性质上相匹配,而且延迟测试时,知觉非流畅可以促进学习,说明该效应存在边界。     

Health Effects of Religion,Spirituality, and Supernatural Beliefs in Mainland China: A Systematic Review

Effects of religion, spirituality and supernatural beliefs (RSS) upon health in mainland China remain poorly understood, despite strong RSS beliefs influencing Chinese society. We conducted a Chinese–English bilingual systematic review to summarize the state of RSS-health research in mainland China. Study quality was assessed using the Critical Appraisal Skills Program tool. We screened 1858 studies, 162 of which were included in the review. From 2000–2004 to 2015–2019, the number of RSS-health studies in China increased from five to 73. However, only 7% of studies were rated as higher quality. Cross-sectional and case–control studies represented the vast majority of study designs (94%) and religious affiliation was the only RSS measure for 58% of studies. Higher, moderate, and lower quality studies indicated that RSS has both beneficial and adverse health implications. RSS-health research in China has accelerated rapidly in the last 20 years, but fundamental gaps in knowledge remain. Longitudinal study designs and nuanced RSS measures are needed to advance understanding of RSS health effects in China.

     

Followers' unclear demands during the COVID-19 pandemic can undermine leaders' well-being: A moderated mediation model from an entrapment perspective

Although effective leaders are important for reducing employee stress during the COVID-19, limited studies have examined how follower behaviors can influence leader stress and well-being during the COVID-19. This study draws on defeat-entrapment theory to examine how followers' unclear demands during the COVID-19 consequently impact leaders' psychological states and well-being. We conducted a three-wave time-lagged investigation with a sample of 281 leaders in the United Kingdom and found that followers' unclear demands could generate feelings of entrapment in leaders, leading to decreased levels of well-being outcomes in leaders. Importantly, we found that leaders who have higher levels of leadership responsibility during the COVID-19 are likely to feel trapped by followers' unclear demands. They are also likely to face higher levels of feelings of entrapment and impaired well-being compared with leaders who have lower levels of leadership responsibility. We discuss the implications for theories and practices, as well as directions for future research.     

催产素影响恐惧习得和消退的认知神经机制

恐惧是一种基本的情绪, 在人类的生存和适应中发挥着重要作用。先前的研究表明, 杏仁核、背侧前扣带回、脑岛等脑区是条件化恐惧习得的认知神经基础, 杏仁核、海马和腹内侧前额叶等脑区在恐惧消退过程中发挥重要作用。研究发现, 催产素与恐惧习得和恐惧消退过程密切相关。恐惧习得过程中, 催产素影响杏仁核、背侧前扣带回的活动, 影响杏仁核与背侧前扣带回和脑干间的功能连接, 促进或抑制恐惧习得过程; 恐惧消退过程中, 催产素影响了杏仁核和腹内侧前额叶的活动, 并且影响杏仁核与内侧前额叶和海马间的功能连接, 促进或抑制恐惧消退过程。未来研究应从性别差异、神经网络模型、身心发育和病理研究等角度展开, 力图深入理解催产素影响恐惧情绪加工的认知神经机制。     

Density evolution during the growth of disc-shaped aluminium nanoparticles on a liquid surface

Aluminium (Al) nanoparticles (NPs) have been successfully fabricated on a liquid surface by thermal evaporation at room temperature. The Al NPs exhibit a disc-shaped morphology with mean diameter and height in the ranges 20–35 and 1.3–3.7?nm, respectively. As the nominal film thickness increases from 0.02 to 0.18?nm, the mean diameter and height are nearly independent of the thickness, implying that the density of the NPs increases during their growth. An explanation for this phenomenon is presented.     

The Tao of a peaceful mind: the representation of emotional health and healing in traditional Chinese literature

This paper explores the representation of emotional health and healing in traditional Chinese literature, and the holistic relationship between traditional Chinese mental medicine and literature as well as philosophy. The philosophical, moral and aesthetic significance assigned to emotional health and healing not only inspired but also mandated the representation of these subjects in Chinese literature. For many Chinese readers, emotional health is more than a medical concern but is integral to their moral and spiritual wholesomeness, the attainment of which necessarily involves the edifying role of literature. The literary representation of emotional health and healing gave rise to a subculture of emotional health and a medical dilettantism in Chinese society. The mutual inclusivity of the professional and the amateurish is peculiar to traditional Chinese mental medicine. While facilitating popular appreciation of emotional health and helping to validate the legitimacy and efficacy of emotional healing, such a phenomenon also caused a certain degree of charlatanization that undercut the rationality and validity of mental medicine. An investigation into the relationship between traditional Chinese literature and mental medicine provides an interdisciplinary perspective from which to examine the latter's history, theory, and practice, thus shedding a cross-cultural light on modern psychology and psychiatry.     

Post-migration Growth Scale for Chinese International Students: Development and Validation

There has been a significant paradigm shift in recent acculturation research from a psychopathological perspective to a resilience framework. However, one indicator of positive adaptation outcomes in acculturation—measurement of personal growth in migration—is lacking. The purpose of this study was to develop and validate a Post-migration Growth Scale (PMGS) for Chinese international students. A 14-item scale was developed through in-depth interviews, item analysis and factor analysis. The scale was initially validated in a sample of 400 mainland Chinese students studying in Hong Kong. Exploratory factor analysis suggested two factors (interpersonal growth and intrapersonal growth), which were cross-validated in an independent sample of Chinese international students in Australia from mainland China (n = 154) by confirmatory factor analysis. The PMGS showed satisfactory internal consistency reliability and concurrent validity. The PMGS can thus be a reliable and valid instrument to measure Chinese international students’ personal growth from overseas study experiences. Limitations were discussed and implications were suggested.     

中国人社会心态的经验结构及量表编制

对当今中国社会心态的研究,因缺乏标准化的测量工具而难以深入。为此,该研究在参考已有研究基础上,确定了生活满意感、社会压力感、政府信任感、社会公平感、社会安全感和社会问题感六个方面的测量指标,选取较大样本经过预测和正式施测,并采用验证性因素分析对量表结构进行验证。结果表明量表具有良好的信度,且结构与数据拟合较好,可以作为对中国人社会心态进行量化研究的测量工具。
