有调节的中介模型检验方法：竞争还是替补?

在心理和其他社科研究领域, 经常遇到中介和调节变量。模型的变量多于3个时, 可能同时包含中介和调节变量, 一种常见的模型是有调节的中介模型。本文检视文献上各种检验有调节的中介模型的方法, 理清方法之间是竞争关系(分清优劣)还是替补关系(分清先后), 在此基础上总结出检验有调节的中介模型的步骤, 并用一个实例进行演示。文中也讨论了有调节的中介模型与有中介的调节模型的联系与区别。     

熟悉性与回想分离的新证据

人们常常发现自己对某一情景有些熟悉, 但又想不起以前有关的经历。对这种熟悉感的理论解释, 一种观点认为熟悉感来自一种较弱的记忆形式, 与有回忆情况下的再认属于同一加工过程(single-process models, SPM)。另一种观点则认为, 熟悉感来自一种基于熟悉性的再认, 与基于回想的再认相互独立(dual-process theories, DPT)。在实验室, 评估熟悉性与回想是否相互独立的基本方法是寻找两者分离的证据。本文尝试梳理无线索回忆再认(recognition without cued recall, RWCR)范式的研究, 结果显示：熟悉性对某种特殊的概念加工和整体特征的知觉加工要比回想更加敏感, 并没有支持SPM关于回想和熟悉性各自对意义加工和局部特征的知觉加工更加敏感的推断。而且RWCR研究还观测到熟悉性与回想在行为和神经成像方面的实验性分离, 支持了DPT关于熟悉性与回想相互独立的推断。最后, 本文从熟悉性的深层机制和中英文材料对RWCR的不同影响出发, 对未来研究提出展望。     

两步火柴棍算术问题解决中的顿悟认知成分分析*

选取68名大学生,随机分为口语报告组和非口语报告组,解决数值型、混合型、分解型、符号型和连等型等五种类型在内的8个两步火柴棍算术问题,以探讨不同难度的两步火柴棍算术问题解决过程中的顿悟认知成分。研究结果:(1)在两步火柴棍算术问题解决过程中,口语报告不存在口语遮蔽效应;(2)两步火柴棍算术问题的难度水平不完全取决于不正确表征;(3)五种题型中都存在失败、僵局和重构三种顿悟认知成分,且都存在自下而上和自上而下两种重构类型。本研究验证了难度水平不同的两步火柴棍算术问题解决过程是一个从分析到顿悟的连续体,即难度较大的连等型和符号型包含的顿悟认知成分较多,更接近顿悟性问题一端,分解型居中,难度较小的混合型、数值型包含的顿悟认知成分较少,更接近分析性问题一端;且自下而上的重构更多存在于顿悟性问题一端。     

What Can Artificial Intelligence Learn from Wittgenstein＇s On Certainty？.

Meta-philosophically speaking, the philosophy of artificial intelligence （AI） is intended not only to explore the theoretical possibility of building ＂thinking machines,＂ but also to reveal philosophical implications of specific AI approaches. Wittgenstein＇s comments on the analytic/empirical dichotomy may offer inspirations for AI in the second sense. According to his ＂river metaphor＂ in On Certainty, the analytic/empirical boundary should be delimited in a way sensitive to specific contexts of practical reasoning. His proposal seems to suggest that any cognitive modeling project needs to render the system context-sensitive by avoiding representing large amounts of truisms in its cognitive processes, otherwise neither representational compactness nor computational efficiency can be achieved. In this article, different AI approaches （like the Common Sense Law of Inertia approach, the Bayesian approach and the connectionist approach） will be critically evaluated under the afore-mentioned Wittgensteinian criteria, followed by the author＇s own constructive suggestion on what AI needs to try to do in the near future.     

Chenyang Li,The Confucian Philosophy of Harmony

The core argument of Chenyang Li＇s new book is that harmony-understood in particular through the categories of ＂deep harmony＂ and ＂creative tension＂-is the central idea of classical Confucianism.     

A Philosophical Analysis of the Concept of Crisis

In our times, philosophy has been suffering from a spiritual crisis that takes the forms of the crisis of culture, the crisis of meaning, and the crisis of way of life. As the soul of culture, philosophy should contribute valuable responses to the problems of our times. Thus understood, this paper intends to analyze the concept of crisis in a phenomenological approach. The concept of crisis is concerned with the philosophical themes of time and death, and the crises of our times are primarily the crises of life-meaning and the life-world. Drawing sources from Husserl and other phenomenologists, as well as experiences from Chinese culture, I argue that a philosophy of crisis should find its point of departure from the crisis of philosophy.     

Edmund Husserl＇s Political Praxis and Theoretical Reflections during World War I

Husserl the philosopher personally experienced World War I breaking out 100 years ago. Like most German and Austrian commoners, at the initial stage of the war, Husserl was extremely passionate for it. After undergoing the cruelty of war and losing many relatives and friends, he was once enmeshed in extreme confusion and disappointment, albeit he still made every effort to offer spiritual and ethical support to the soldiers at the front. Along with the proceeding of the war, he soon changed his views with respect to this war and confessed that more and deeper reflections were needed to address issues about problems of nationality, super-national ethics and about problems of wars relevant to them. He made philosophical theoretical reflections with regard to this war after it ended, and presented, eventually, requirements for himself： to be satisfied with taking the possibility of the practical activities of philosophy as the topic of philosophical theoretical study and to give up, in drastic fashion, the intention in such philosophical practices as providing political proposals and exerting political influences, ＂living purely as a scientific philosopher.＂     

问题解决中顿悟的原型位置效应的fMRI研究

科学发明创造中, 人们往往对一个问题百思不得其解, 但在看到某一启发性事物(原型)时, 突然产生顿悟, 继而发现解决问题的新思路。本研究以科学发明创造问题为实验材料, 采取“先呈现问题、后呈现原型”和“先呈现原型、后呈现问题”两种范式, 探讨问题解决中顿悟的原型位置效应, 并采用fMRI技术记录大脑的BOLD信号变化。结果发现：行为结果上, “问题在先”条件下正确率显著高于“原型在先”条件; 大脑激活结果上, 问题先导条件下的原型启发的大脑机制主要表现为左侧颞中回(left middle temporal gyrus)和左侧额中回(left middle frontal gyrus)的显著激活, “原型在先”条件下, 主要激活左侧扣带回(left cingulate gyrus)、左侧中央前回(left middle frontal gyrus)。     

变革型领导对员工绩效和满意度的影响：心理资本的中介作用及程序公平的调节作用

通过对国内一家企业共785位员工及其直接主管的问卷调查, 考察了下属心理资本在变革型领导与下属工作绩效及满意度之间关系的中介作用以及程序公平对该关系的调节作用。研究结果显示：1)下属的心理资本与其工作绩效和满意度正向相关; 2)下属的心理资本部分中介了变革型领导对下属工作绩效及满意度的正向关系; 3) 下属的程序公平调节了变革型领导对下属心理资本的影响。具体而言, 下属的程序公平感越高, 变革型领导与下属心理资本的正向关系越强, 反之越弱; 4) 进一步地, 程序公平调节了下属心理资本对变革型领导－工作绩效和满意度的中介作用, 即：程序公平感越高, 变革型领导通过心理资本对下属的工作绩效和满意度所产生的作用就越强, 反之越弱。最后讨论了该研究的理论意义和应用价值。     

安全动机在安全绩效模型中的作用：自我决定理论的视角

在日常工作中, 安全动机是员工保持安全行为的重要决定因素。安全动机对安全绩效的影响虽然已引起研究者的关注, 但相关的实证研究缺少清晰的理论界定和有效的测量工具。本项目拟在安全绩效模型的基础上, 借鉴自我决定理论对动机的分类, 将安全动机的类型进行扩展, 并在多层次模型中探讨安全动机在变革型领导、个体特征和安全绩效之间的中介作用, 以及在中国管理背景下可能存在的边界条件。研究将结合访谈、问卷和情境实验等方法对上述变量间关系进行相关和因果关系的探讨。本项目将自我决定理论与安全绩效模型相结合, 可以为安全研究的动机理论发展做出贡献; 研究结果亦可为安全管理实践提供评价工具和有效指导。
