指动脉背侧支皮瓣在手指末节皮肤缺损治疗中的临床应用

分析指背动脉背侧支与其血管网联合供血滋养皮瓣在指末端皮肤缺损的修复中的应用效果。取中节手指固有动脉的背侧支为蒂血管,逆行切取指背皮瓣31例共35指,移植修补位于远端指间关节或其远端的皮肤缺损。若同时伴有骨、关节、肌腱等的损伤,则予以同期修复。本研究中最大切取皮瓣1.5cm×3.5cm,平均随访6±0.5个月(3至9个月),皮瓣成活率100%,皮瓣两点辨别觉9±0.2mm,95%的患者具有良好的指间关节活动能力。因此,指动脉背侧支皮瓣手术操作简单,术后成功率高且患者恢复效果好。     

个体情绪智力与任务绩效：社会网络的视角

基于社会网络视角, 分别以社会资本的关系性维度为中介变量, 以社会资本的结构性维度为跨层调节变量, 探讨了个体情绪智力对任务绩效的影响。通过收集模拟网络实验背景中46个项目团队210位个体的调查数据, 运用多元统计分析方法对提出的假设模型进行了实证检验。研究发现：在控制个性的前提下, 关系性社会资本在个体情绪智力影响任务绩效过程中起到中介作用, 结构性社会资本(咨询网络密度)跨层正向调节影响个体情绪智力与任务绩效的关系。结果表明, 不同层次的社会资本及其维度在情绪智力影响绩效过程中扮演着不同角色, 运用社会资本概念框架有助于解释情绪智力的作用机制。     

基于系统动力学的群体情绪传播模型

选取某高校20个教学班级共计614人为被试,采用心理学实证与系统动力学（system of dynamic）与社会网络（social network）建模相结合的研究方法,对群体情绪传播的动力学规律进行了建模,并将模型仿真结果与心理实验结果进行了比对。结果表明,所建立的模型能够较好地刻画出群体情绪传播的动力学规律,具有较高的生态效度。该模型的建立对群体性事件的定量预警与监控提供了基础理论依据。     

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.     

想象未来的认知加工成分及其脑网络

合理预期和想象未来事件或场景, 有利于个体做出适应性反应, 促进生存与发展。近年来, 研究者对想象未来的认知加工成分和神经机制进行了深入探讨, 提出了想象未来的相关概念和理论。我们首先概述了想象未来实验常用的思维采样范式和词语-线索范式, 接着介绍了想象未来的自我参照加工、心理场景构建等认知加工成分。此外, 特别介绍了想象未来的默认网络模型以及与之相关的其他大尺度脑网络, 并进一步提出了想象未来的脑网络研究框架。未来的研究可从想象未来的动态脑网络、复杂脑网络以及与疾病的关系等角度入手, 深入探究想象未来的神经机制。     

孤独症儿童共同注意的神经基础及早期干预

共同注意是指两个人共同对某一事物加以注意, 分享对该事物的兴趣, 它是儿童社会认知发展的奠基性能力。首先, 孤独症儿童共同注意发展主要体现在注视转换、主动展示、分享等能力发展滞后及缺陷; 孤独症儿童共同注意的神经基础：应答性共同注意主要涉及后部皮层注意网络(如颞上沟后部、顶内沟等), 自发性共同注意涉及前部皮层注意网络(如前扣带皮层、背内侧额叶等); 最后, 以回合式教法和关键反应训练为基本方法, 论述了共同注意干预的新近模式和效果评估。未来研究应在孤独症儿童的共同注意发展的年龄特征及机制、共同注意的脑区可塑性及脑网络的发展以及开发更有效的干预方法等方面展开大量研究。     

道德直觉决策及其机制探析

道德直觉决策研究是从直觉思维角度探讨决策者在道德境遇下的决策。道德直觉决策是道德情境下的直觉反应, 其理论基础包括躯体标记假说、社会直觉模型、双加工理论、事件特征情感复合体系以及双系统理论; 道德直觉决策机制至少包括：无意识加工、情绪加工和直觉加工三个基本的心理加工过程, 与之对应的神经系统则至少存在三个可能的脑神经回路：无意识加工的道德脑区、情绪加工的道德脑区和直觉加工的道德脑区。研究主要从客观和主观两方面分析了道德直觉决策的一般性影响因素--文化、道德境遇、经验、情绪和道德直觉; 揭示了道德直觉决策的加工机制。未来研究应在加强理论建构的基础上, 通过更缜密细致的实验设计去探究决策过程中各因素的交互作用, 并明确道德脑区之间的联结。     

Methodological naturalism and epistemic internalism

Epistemic naturalism holds that the results or methodologies from the cognitive sciences are relevant to epistemology, and some have maintained that scientific methods are more compatible with externalist theories of justification than with internalist theories. But practically all discussions about naturalized epistemology are framed exclusively in terms of cognitive psychology, which is only one of the cognitive sciences. The question addressed in this essay is whether a commitment to naturalism really does favor externalism over internalism, and we offer reasons for thinking that naturalism in epistemology is compatible with both internalist and externalist conceptions of justification. We also argue that there are some distinctively internalist aims that are currently being studied scientifically and these notions, and others, should be studied by scientific methods. This essay is dedicated to Deborah Mayo, who has long advocated using error statistical techniques to analyze and resolve epistemological puzzles in the philosophy of science. This essay follows the same spirit by advocating that computational concepts and techniques be applied within the heart of traditional, analytic epistemology.     

多备择决策的联结网络模型

关于选择偏好可变性的心理机制,新联结主义框架下的联结网络模型强调决策是动态的随机的过程.其中,多备择决策场理论强调由心理场距离决定水平抑制强度的线性关系,渗漏竞争累积模型强调主观价值评价过程中非线性的规避损失偏向.     

Monotonicity and Reasoning with Exceptions

A proposal by Ferguson [2003, Argumentation 17, 335–346] for a fully monotonic argument form allowing for the expression of defeasible generalizations is critically examined and rejected as a general solution. It is argued that (i) his proposal reaches less than the default-logician’s solution allows, e.g., the monotonously derived conclusion is one-sided and itself not defeasible. (ii) when applied to a suitable example, his proposal derives the wrong conclusion. Unsuccessful remedies are discussed.
