有关条件推理认知机制的概率理论

条件推理主要有两种研究范式：演绎形式(MP、DA、AC、MT)和变通形式(四卡问题)。已往研究主要探讨了内容因素、情境因素以及元认知因素等对条件推理的影响,形成了若干理论模型和观点。近来、Oaksford等人研究了概率因素对条件推理的影响．提出了条件概率模型。本文对这种新的研究取向作了详细的介绍和评价,并对未来研究进行了展望。     

Dynamic Creative Interaction Networks and Team Creativity Evolution: A Longitudinal Study

To assess the dynamical effects of creative interaction networks on team creativity evolution, this paper elaborates a theoretical framework that links the key elements of creative interaction networks, including node, edge and network structure, to creativity in teams. The process of team creativity evolution is divided into four phases, including formation, growth, maturity and decline/restart. The importance of domain‐relevant knowledge, creativity‐relevant skill, interaction frequency, interaction length, network density and closeness centrality are emphasized in specific phases of team creativity evolution in a complex creative context. To test our assumptions, a longitudinal study of creative teams in a “Challenge Cup” Creative Business Plan Competition for university students is performed and the full networks of 17 creative entrepreneur teams are mapped. Both static comparison and dynamic analysis are conducted to analyze the relationship between creative interaction networks and team creativity evolution. For specific phases of team creativity evolution, we find confirmation of our predictions. The implications of dynamic creative interaction networks for all the phases of creative teams from formation to decline/restart are discussed.     

汉语声调水平映射规则的内隐学习及其长度迁移效应

内隐学习领域关注的重要问题是被试能够习得何种结构及其相应的学习机制。远距离规则的研究为澄清这一问题提供了新的视角。现有研究已证实被试能够内隐地习得并迁移固定长度的远距离规则。按照内隐学习抽象性的观点,如果被试习得的是远距离的抽象规则本身,那么迁移也同时会发生在不同长度的材料上。因此,研究以独特的汉语声调水平映射规则为材料,通过对表面特征与底层规则之间的分离操作,探讨声调水平映射规则的内隐习得和长度迁移,结果表明被试不仅能够习得这一规则,还能够将该规则灵活迁移到不同长度的材料上,进一步为内隐学习的抽象性特点和无限性的学习机制提供强有力的新证据。     

宗教研究的认知科学新取向

宗教认知科学是新近出现的从认知和进化的角度研究宗教的分支学科。主要有认知副产物和社会适应两种理论。认知副产物理论认为宗教信仰是人类认知倾向的副产物;社会适应理论认为宗教信仰促进群体的团结合作,是一个精巧的社会适应机制,有助于群体的自然选择。两种理论引发了系列的实验研究,由于宗教认知科学仍处于理论研究向实证研究的过渡阶段,未来需统一概念,加强实验范式的建立,更多地借助认知科学的方法和工具开展实证研究。     

论维特根斯坦的“哲学语法”概念

<正>近些年来,国内外哲学界在维特根斯坦思想研究中,逐渐关注到维特根斯坦的"哲学语法",特别是试图从当代哲学的视角解读他的语法概念的思想内容。(Forster;陈嘉映;韩林合,第11章)我在阅读过程中发现,维特根斯坦对"语法"概念的使用完全不像我们想象的那样严格,而如何理解其"哲学语法"概念,实际上意味着如何理解维特根斯坦哲学。     

后现代心理治疗及其伦理问题思考

文章通过论述后现代对现代认识论和思维模式的质疑与超越,分析了后现代语境下心理治疗与现代心理治疗的差异,并关注在后现代这一新的思维模式下,心理治疗领域可能产生的伦理问题。作者指出,后现代心理治疗的不确定性、价值干预和文化介入,使心理治疗的伦理挑战被进一步复杂化,对治疗师也提出了更高要求。     

Associative learning improves visual working memory performance

The ability to remember visual stimuli over a short delay period is limited by the small capacity of visual working memory (VWM). Here the authors investigate the role of learning in enhancing VWM. Participants saw 2 spatial arrays separated by a 1-s interval. The 2 arrays were identical except for 1 location. Participants had to detect the difference. Unknown to the participants, some spatial arrays would repeat once every dozen trials or so for up to 32 repetitions. Spatial VWM performance increased significantly when the same location changed across display repetitions, but not at all when different locations changed from one display repetition to another. The authors suggest that a major role of learning in VWM is to mediate which information gets retained, rather than to directly increase VWM capacity.     

对保乳手术及预防性乳腺切除术的思考

鉴于对乳腺癌是全身性疾病的认识,为提高术后生存质量,目前乳腺癌治疗中保乳手术日益受到重视.而为了阻断高危险性的乳腺向乳腺癌发展,预防性乳房切除术也正在被患者接受.保留乳腺与预防性切除乳腺的医学实践反映了目前人们对乳腺癌的深层认识,值得深入思考.     

德性论与伦理学

伦理学中有价值论、规范论或义务论,但没有专门研究德性问题的德性论.德性问题是一个重要的人生问题,也是一个重要的社会问题,尤其是当代社会的严重问题,而且只有伦理学才能从理论和实践的结合上给予系统的回答.因此,应该建立德性论专门研究德性问题.德性论研究什么是德性以及如何形成德性的问题,其主要任务是确立伦理学的德性原则.德性论与价值论、规范论一起分别从人的品质、目的、行为方面解释和回答人生问题,它们是相对独立、相互补充的,共同给人生提供伦理学原则并研究回答人生的伦理学问题.德性伦理学属于德性论的研究,但德性伦理学是西方伦理学的一个流派,而不是伦理学的一个相对独立的分支.     

Investigating the role of response in spatial context learning

Recent research has shown that simple motor actions, such as pointing or grasping, can modulate the way we perceive and attend to our visual environment. Here we examine the role of action in spatial context learning. Previous studies using keyboard responses have revealed that people are faster locating a target on repeated visual search displays ("contextual cueing"). However, this learning appears to depend on the task and response requirements. In Experiment 1, participants searched for a T-target among L-distractors and responded either by pressing a key or by touching the screen. Comparable contextual cueing was found in both response modes. Moreover, learning transferred between keyboard and touch screen responses. Experiment 2 showed that learning occurred even for repeated displays that required no response, and this learning was as strong as learning for displays that required a response. Learning on no-response trials cannot be accounted for by oculomotor responses, as learning was observed when eye movements were discouraged (Experiment 3). We suggest that spatial context learning is abstracted from motor actions.
