记忆提取促进学习:实验证据与机制解释

人类学习的主流观点认为学习主要发生在编码阶段,记忆提取本身并不产生和促进学习。但最近多项研究对此提出了质疑,他们发现,在学习过程中,记忆提取更能促进学习内容的长时保持。本文首先对记忆提取促进学习的实验证据做简要梳理;之后重点介绍关于记忆提取促进学习的多种解释机制,主要包括:侧重于从理论机制层面解释的记忆失用新理论,强调内在精细机制的精细提取假设,以及解释保持间隔(长、短)与学习方式(重复学习、学习-测试)交互作用的基于分布的二分模型;文章最后分析了当前研究记忆提取作用实验存在的一些问题,提出了今后的研究方向,强调应从多角度揭示记忆提取练习促进学习的机制。     

Neuroticism,conscientiousness and fruit consumption: Exploring mediator and moderator effects in the theory of planned behaviour

Integrating the theory of planned behaviour (TPB) with the five-factor model (FFM) of personality may provide insight into the cognitive and motivational mechanisms linking personality with health behaviour, but this issue has received very little attention regarding fruit consumption. Mediator effects of TPB concepts in the personality–fruit consumption link, as well as moderator effects of personality in the intention–fruit consumption link, were therefore investigated in the present study. Data on fruit consumption, TPB concepts and FFM dimensions were gathered among 405 respondents in face-to-face interviews using questionnaires. Structural equation modelling was used to investigate the mediator and moderator effects. The direct effect of conscientiousness on fruit consumption was mediated by attitude and perceived behavioural control, while no direct effect of neuroticism on fruit consumption was found. Neuroticism moderated the intention–fruit consumption relationship with the weakest relationship for those scoring high on neuroticism. Conscientiousness did not moderate the intention–fruit consumption relationship. TPB variables are mediators in the conscientiousness–fruit consumption link. Whether fruit consumption is intentional may be dependent upon the personality dimension neuroticism. Personality dimensions may be a useful addition to the TPB and should be considered in health behaviour change interventions.     

复兴国家:国家理论的新形态

民族国家的架构尽管日益式微,但它在组织全球化经济、全球化政治和正在形成的全球公民社会中仍然占有首要地位。民族国家不是在消亡,而是正在被重新想象、重新设计、重新调整方向以回应一系列挑战。相应地,对国家的研究在现时代仍然具有重要意义,在全球化背景下,全球资本、全球公民社会、全球治理与民族国家的关系研究构成了国家理论的新形态。     

"歷数"和"尚贤"与禅让说的兴起

尧舜禅让,古代以为信史。20世纪20年代,有学者提出异议,以为它只是一个传说,这传说是禅让思想的一部分,出自墨家的创造。揆诸史籍,可知,墨家的确传诵过尧举舜而立为天子的故事,对禅让说的传播有推波助澜的作用,但那只是出于宣传尚贤尚同主义的需要,为选官治官而设,并非严格意义上的禅让说。而在儒家,孔子早就盛赞尧舜;尧舜禅让以及与之直接相关的歷数观念在今本《论语》中又有明确反映,这个观念在从周公到孔子的儒家渊源中有着丰富的资源;儒家数观的实质是天命有德,儒家的天命有德思想可为禅让说提供直接的理论基础和前提,儒家的尊贤、墨家的尚贤,后世与“禅让”直接相关的新五德终始说,都可纳入其中。春秋战国时期禅让说的兴起,儒家有直接的关系。     

Children's Understanding of Behavioral Consequences of Epistemic States: A Comparison of Knowledge,Ignorance, and False Belief

The author addressed the issue of the simultaneity of false belief and knowledge understanding by investigating children's ability to predict the behavioral consequences of knowledge, ignorance, and false belief. The second aim of the study was to explore the role of counterfactuals in knowledge understanding. Ninety-nine (99) children, age 3–7 years old, completed the unexpected transfer task and a newly designed task in which a protagonist experienced 1 of the following 4 situations: knowing a fact, not knowing a fact, knowing a procedure, and not knowing a procedure. The results showed that factual ignorance was as difficult as false belief for the children, whereas the other conditions were all easier than false belief, suggesting that the well-known lag between ignorance and false belief may be partly methodologically based. The results provide support for a common underlying conceptual system for both knowing and believing, and evidence of the role of counterfactual reasoning in the development of epistemic state understanding. Methodological variations of the new task are proposed for future research.     

Resilience and quality of life among empty nesters in China: the mediating role of the source of support

Abstract

This study aims to explore the correlations among resilience, social support, and quality of life (QOL) in empty nesters to comprehend whether various sources of social support indirectly affected the correlation between resilience and QOL. We used hierarchical multiple regression analysis and structural equation modeling method in this study. Resilience and support from both family members and friends significantly correlated with the QOL. Besides, both types of support played vital roles in the mediating effects on the correlation between resilience and QOL among empty nesters residing in China. Hence, the hypothesis proposed was confirmed partially. Furthermore, this study offers a comprehensive understanding of overall mental and physical health among empty nesters.     

目标包含结构的文本阅读中目标信息的激活

探讨读者在阅读目标包含结构的文本时,目标信息的恢复激活的条件。运用移动窗口技术,采用3（已经实现、尚未实现与控制条件）×3（强目标愈合信号、弱目标愈合信号与无目标愈合信号）的实验设计。结果是子目标实现与否有主效应,目标愈合信号有主效应,目标实现条件和目标愈合信号有交互作用。结论是在目标包含结构的文本阅读中,目标信息表现出恢复激活的方式,目标愈合信号是目标信息恢复的必要条件,弱的目标愈合信号就可以激活长时记忆中已实现的目标信息,而较强的目标愈合信号才能激活长时记忆中尚未实现的目标信息     

社会心理学视角下权力理论的发展与比较

权力作为人类社会的基本特征之一, 一直受到社会心理学家的关注, 实证研究成果丰硕, 理论构建也日益完善。首先, 权力从结构变量发展为心理变量, 有外显、内隐之分, 控制感是其核心要素。其次, 社会心理学领域最具代表性的3个权力理论为“接近-抑制理论”、“情境聚焦理论”和“社会距离理论”, 它们的理论基础各异, 关注的现象却存在交集。最后, 未来的权力研究可以从以下3个方向改进：(1)关注文化、动机、自我卷入等因素; (2)区别社会权力和个人权力; (3)融合各领域观点; (4)丰富研究方法, 以促进理论的发展。     

Couple adjustment to a stressful life event: a dyadic investigation of the roles of positive reframing and perceived benefits

Background and Objectives: This study examines positive reframing (a form of meaning making), perceived benefits (a form of meanings made) and adjustment in couples who experienced a stressful life event in the past year. This study tested whether couple members’ scores were nonindependent and whether one’s own perceived benefits was predicted by their own positive reframing (actor effect) as well as their partner’s positive reframing (partner effect). Further, this study tested actor and partner effects for the link between perceived benefits and adjustment and whether positive reframing (the initial variable) works through perceived benefits (the mediator) to affect adjustment (the outcome) at the dyadic level.

Design: A standard dyadic design was used.

Methods: Eighty couples completed measures of positive reframing, perceived benefits, and adjustment (depression, anxiety, positive affect, life satisfaction, and relationship satisfaction).

Results: Partners’ scores on study variables were related, and although only actor effects were found for the path between positive reframing and perceived benefits, both actor and partner effects were found for the path between perceived benefits and adjustment. Mediation was found for actor–actor and actor-partner indirect effects.

Conclusions: Results indicate that a greater focus on interpersonal factors is needed to further meaning-making theory and inform practice.     

Contrast Effects and Approval Voting: An Illustration of a Systematic Violation of the Independence of Irrelevant Alternatives Condition

In approval voting, voters indicate all alternatives acceptable to them, instead of indicating their most preferred alternative. This study sought to examine the hypothesis that, under certain conditions, approval voting systematically violates a rationality condition of social choice: the independence of irrelevant alternatives condition. Given a well-known psychological phenomenon, the contrast effect, it was hypothesized that sets of acceptable alternatives might be changed as a result of changes in unacceptable alternatives. This hypothesis was tested in a sample of undergraduates who were presented with fictional profiles of juvenile delinquents and then were asked whether they should be granted parole. The outcomes of approval voting changed merely as the result of a change in an alternative least preferred by all voters.     

The Analysis of Intervention Change in Children and Families: Methodological and Conceptual Issues Embedded in Intervention Studies

This article provides an overview of methodological and conceptual issues underlying the assessment of change during psychotherapy with children and families. Three central considerations are discussed: (1) What changes do we measure? (2) When do we measure change? (3) How do we measure change? The difficulties with the traditional methods of assessing change are highlighted, and suggestions for a new paradigm that calls for expansion of the nomological network relevant to the analysis of change, as well as the inclusion of more assessment points and more reliable and valid measures of the change process, are presented. Illustrations of key points are provided from the Adolescent Transitions Program, a theoretically based intervention program targeting high-risk youth.     

"仁"——医德的元德

医德是医学道德的简称,具言之,它是指医务人员在医疗卫生服务的职业活动中应该具备的仁爱、救死扶伤等的品德,是道德德目在医务人员身上的内化,也是对医务人员必须具备的最起码的要求.我们评价一个医生,首先是直面他的医德,医德是医生形象的体现,没有医德的医生即使技艺再高超,也算不上一个完整意义上的医生,"无德不成医".事实上一个医德低下的医生,他的技艺也不会高超的.     

Mediation analysis of decisional balance,sun avoidance and sunscreen use in the precontemplation and preparation stages for sun protection

Objective: Mediation analyses of sun protection were conducted testing structural equation models using longitudinal data with three waves. An effect was said to be mediated if the standardised path between processes of change, decisional balance and sun protection outcomes was significant.

Design: Longitudinal models of sun protection using data from individuals in the precontemplation (N = 964) and preparation (N = 463) stages who participated of an expert system intervention.

Main outcome measures: Nine processes of change for sun protection, decisional balance constructs of sun protection (pros and cons), sun avoidance behaviour and sunscreen use.

Results: With the exception of two processes in the preparation stage, processes of change predicted the pros (r = .126–.614), and the pros predicted the outcomes (r = .181–.272). Three models with the cons as mediator in the preparation stage, and none in the precontemplation stage, showed a mediated relationship between processes and outcomes.

Conclusion: In general, mediation analyses found both the process of change-to-pros and pros-to-behaviour paths significant for both precontemplation and preparation stages, and for both sun avoidance and sunscreen use outcomes. Findings provide support for the importance of assessing the role of underlying risk cognitions in improving sun protection adherence.     

"[人]在[大场所]"材料范式下观察不到信息整合的原因初探

本研究采用扇效应技术来探求推翻G．A．Radvansky针对其1993年研究结果所作解释的证据。共分为两个分实验。实验1重复Radvansky1993年研究中的实验三,以取得中文材料的基线值,为实验2做准备;实验2通过在材料中使用同样具有可“移动性”的物体的概念(例如快餐车)来探讨“可移动性”是否是“[人]在[大场所]”材料范式下观察不到信息整合的根本原因。结果表明“人的可移动性”不是“[人]在[大场所]”．材料范式下观察不到信息整合的原因。     

Sense of community improves community participation in Chinese residential communities: The mediating role of sense of community responsibility and prosocial tendencies

Community participation is essential for community development and enhancing quality of life. Several studies have focused on the relationship between sense of community (SOC) and community participation in organizational settings. Guided by the community experiences framework, this study aims to examine how a SOC improves community participation in Chinese residential communities. Moreover, the study aims to assess the mediating role of SOC responsibility (SOC-R) and prosocial tendencies in that relationship. A sample of 433 residents completed questionnaires regarding their SOC, sense of community responsibility, prosocial tendencies, and community participation. Using a linear regression model, we found that a SOC can positively predict the level of community participation. Mediation effect analysis revealed that a SOC-R mediated the relationship between SOC and community participation. In addition, prosocial tendencies mediated the association between the SOC and community participation. Using multiple mediation analysis, we found that SOC-R and prosocial tendencies mediated the link between a SOC and community participation in a sequential manner. The findings of this study complement existing research by uncovering the mechanism underlying the relationship between a SOC and community participation.     

疫病与外交：清末民初华洋互动视域下的瘟疫防治

瘟疫贯穿人类历史发展始终。近代以降,由于列强势力深入中国各地,围绕瘟疫防治而产生的华洋互动日趋频繁。一方面,外侨主导的防疫事业引发了中国社会各阶层收回防疫主权的外交诉求;另一方面,列强以防疫之名行侵略之实的行为使得华洋之间围绕国权展开了艰难博弈。在此过程之中,近代中国政府通过完善其行政能力,更有力地介入到防疫领域的管理中,推动了防疫事业的制度化发展,并以外交的方式维护公共卫生领域的国权,从而在应对公共卫生事件中逐步走向成熟。

     

From the Universe of Knowledge to the Universe of Concepts: The Structural Revolution in Classification for Information Retrieval

During the twentieth century, bibliographic classification theory underwent a structural revolution. The first modern bibliographic classifications were top-down systems that started at the universe of knowledge and subdivided that universe downward to minute subclasses. After the invention of faceted classification by S.R. Ranganathan, the ideal was to build bottom-up classifications that started with the universe of concepts and built upward to larger and larger faceted classes. This ideal has not been achieved, and the two kinds of classification systems are not mutually exclusive. This paper examines the process by which this structural revolution was accomplished by looking at the spread of facet theory after 1924 when Ranganathan attended the School of Librarianship, London, through selected classification textbooks that were published after that date. To this end, the paper examines the role of W.C.B. Sayers as a teacher and author of three editions of The Manual of Classification for Librarians and Bibliographers. Sayers influenced both Ranganathan and the various members of the Classification Research Group (CRG) who were his students. Further, the paper contrasts the methods of evaluating classification systems that arose between Sayers’s Canons of Classification in 1915–1916 and J. Mills’s A Modern Outline of Library Classification in 1960 in order to demonstrate the speed with which one kind of classificatory structure was overtaken by another.

论健康伦理学及其基本理论架构——“九大理论”视野中的健康伦理

当代医学道德发展的走向理应是健康道德,后医学伦理学时代理应是健康伦理学。建设健康伦理学需要搭成一个基本理论架构。其组成至少应该有“九大理论”,即生命神圣论、生命质量论、生命价值论,医学人本论、医学功利论、医学公正论,医者美德论、医者义务(患者权利)论、医患和谐论。其间,按顺序由每三论构成一个“统一论”,将第一个“统一论”作为立论前提,将第二个“统一论”作为直接依据,将第三个“统一论”作为应用指南,如此,才能由三个“统一论”共同地更好地阐释全部健康伦理学问题。     

春秋战国哲学流派研究的反思

经过几十年的积淀,春秋战国哲学流派研究取得了丰硕的成果,但是也存在着需要认真反思的地方。春秋战国哲学流派历史价值认识不充分,哲学阵线的机械划分,哲学范畴、概念的教条比附,文献资料理解的歧义,简牍帛书的利用不足,指导理论的简单化、研究方法的单一化等,分别从不同的侧面制约着春秋战国哲学流派研究的深入发展,也影响着对中国古代哲学的精确理解。     

Giotto in Padua: A New Geography of the Human Soul

In the Arena Chapel in Padua, Giotto painted seven allegorical representations of virtues and seven allegorical representations of vices. This article probes the sources for the list of virtues and the list of vices. The ensemble of virtues can be located in St. Thomas Aquinas; the ensemble of the vices, however, is original. The result is a new account of vices that displaces the odler account of the “seven deadly sins.”
