Luck and Risk

This paper advances new theses about the relationship between luck and risk, using recent work by Duncan Pritchard (2014, 2015, 2016) as its foil. Once Pritchard’s views are introduced in section 1 , the rest of the paper completes two different tasks, one critical and one constructive. By focussing on some epistemological cases that Pritchard’s model would fail to identify, section 2 shows that it relies on a difference that is in fact inessential: the one between the occurrence and the non‐occurrence of an event. Section 3 sketches and defends an alternative account of the luck/risk distinction, based on the consideration of situations (instead of events) from different temporal perspectives: luck assessments track a situation’s past, considering it the actual outcome of some previous event, whereas risk assessments look at the situation’s future, regarding it as the initial condition of some unsettled event.     

时序知觉影响因素与思考

时序知觉是在几十毫秒到几百毫秒内, 对事件的同时性、非同时性和顺序性的知觉。对时序知觉的影响因素的探索可分为自下而上和自上而下两种研究取向。自下而上的研究探讨刺激的物理特征、被试的生物学特征, 以及实验方法对时序知觉的影响。而自上而下的研究探讨因果信念、情绪、文化对时序知觉的影响。今后的研究还应结合行为实验与神经科学技术, 深入探讨时序知觉的两种加工方式是分离的还是同时进行的, 以及揭示控制时序加工的脑区。     

视听整合加工及其神经机制

通常人们接收到来自不同感觉通道的信息时, 首先在大脑中各个分离的区域单独进行加工处理, 而后在多感官区进行整合。前人关于言语感知中视听整合加工的神经成像研究认为, 视觉和听觉信息能够相互影响; 两者进行整合的关键区域是人脑左后侧的颞上沟, 其整合效应受时间和空间因素的限制。未来的研究应致力于建立更加合理的实验范式和数据分析方法来探讨整合加工的脑区机制, 把多感官整合研究进一步延伸到更加复杂的领域。     

心理时间的分割与整合

在心理时间的研究中存在两种观点。一种观点认为,心理时间是以整合的方式呈现,心理时间的整合是对各种实验结果所得出的时间经验的概括与综合。另一种观点将心理时间进行分割,时序信息加工通过知觉重组和外部计数操作反映出来,这些活动受一个目标间隔内发生的事件结构的层次性所支配,分割心理时间的观点强调时距估计中期望的作用,但它不能解释非时序信息加工路径的影响。     

时序知觉的启动效应

时序知觉中的启动效应是指被启动的刺激被知觉为先于未启动刺激出现。文章综述了时序知觉启动效应的有关理论解释和影响因素,并对现有研究存在的问题及未来研究的方向进行了讨论。

Passion, Pain, and Purpose: One Man’s Response to the Passion of the Lord

The purpose of this article is to review and comment on the book The Passion of the Lord: African American Reflections. Edited by James A. Noel and Matthew V. Johnson, and published by Facets (an imprint of Fortress Press: Minneapolis), the book explores the unique perspective of African American thought in relation to the story of the Passion of Christ, and the cultural aesthetics which allow Christ’s suffering on the cross to become a powerful agent of spiritual strength, hope, love, and faith. This article records one African American man’s deep personal engagement of, and resonance to, the material as he validates, affirms the important insights of the seven theologians presented. Through personal observation and experience, poetry and relevant cultural idioms, the author honors work which, ultimately, contributes to a vitally important self-understanding of who African Americans are now, where they are now, and how they have come to be the people they are now in America.

On the consistency problem for the calculus

In this paper, we further investigate the consistency problem for the qualitative temporal calculus introduced by Pujari et al. [A.K. Pujari, G.V. Kumari, A. Sattar, INDU: An interval and duration network, in: Australian Joint Conference on Artificial Intelligence, 1999, pp. 291–303]. We prove the intractability of the consistency problem for the subset of pre-convex relations, and the tractability of strongly pre-convex relations. Furthermore, we also define another interesting set of relations for which the consistency problem can be decided by the -closure method, a method similar to the usual path-consistency method. Finally, we prove that the -closure method is also complete for the set of atomic relations of implying that the intervals have the same duration.
