文本阅读中时间信息加工特点及二阶段模型的建构

时间信息的加工一直是当代阅读心理研究的热点。以往研究对时间信息表征的性质、维度特征、提取机制等问题存在诸多争论, 主要表现为强印象假设与场景理论的冲突。我们认为, 文本阅读中时间信息的加工包括两个阶段：加工时间词以及低水平的更新情景模型阶段和通达与整合先前信息阶段, 强印象假设和场景理论争论的实质在于前者解释的是加工的第一个阶段, 而后者解释的是加工的第二个阶段, 因此, 总是难以调和。本项目首先在更高的理论层面上将二者加以整合, 然后采用经典的认知心理学研究方法与现代的眼动研究技术相结合的方法, 通过对文本阅读中时间信息表征性质、加工的维度特征、提取过程的激活与抑制特征等问题的探讨, 为本项目提出的时间信息加工的二阶段模型提供行为实验与眼动实验证据, 从而解决该领域中强印象假设与场景理论的长期争论。本项目的理论构想与研究技术对文本阅读其他问题的探讨具有重要的方法论意义。     

Neural substrates of cognitive skill learning in Parkinson's disease

While cognitive skill learning is normally acquired implicitly through frontostriatal circuitry in healthy individuals, neuroimaging studies suggest that patients with Parkinson's disease (PD) do so by activating alternate, intact brain areas associated with explicit memory processing. To further test this hypothesis, 10 patients with PD and 12 healthy controls were tested on a modified, learning version of the Tower of London task while undergoing positron emission tomography at four different time points over the course of learning. Despite having less accurate problem solving abilities than controls, PD patients were able to acquire the skill learning task. However, as compared to controls, they maintained higher levels of cerebral blood flow activity in the dorsolateral prefrontal cortex and hippocampus and showed an increase in activity in the frontopolar cortex and posterior cingulate over the course of learning. These findings reflect a shift to the explicit memory system in PD patients, enabling them to learn this cognitive skill, which is normally acquired by control subjects using implicit learning strategies and frontostriatal circuitry.     

Quantification over Sets of Possible Worlds in Branching-Time Semantics

Temporal logic is one of the many areas in which a possible world semantics is adopted. Prior's Ockhamist and Peircean semantics for branching-time, though, depart from the genuine Kripke semantics in that they involve a quantification over histories, which is a second-order quantification over sets of possible worlds. In the paper, variants of the original Prior's semantics will be considered and it will be shown that all of them can be viewed as first-order counterparts of the original semantics.     

Beyond Fear Emotional Memory Mechanisms in the Human Brain

ABSTRACT— Neurobiological accounts of emotional memory have been derived largely from animal models investigating the encoding and retention of memories for events that signal threat. This literature has implicated the amygdala, a structure in the brain's temporal lobe, in the learning and consolidation of fear memories. Its role in fear conditioning has been confirmed, but the human amygdala also interacts with cortical regions to mediate other aspects of emotional memory. These include the encoding and consolidation of pleasant and unpleasant arousing events into long-term memory, the narrowing of focus on central emotional information, the retrieval of prior emotional events and contexts, and the subjective experience of recollection and emotional intensity during retrieval. Along with other mechanisms that do not involve the amygdala, these functions ensure that significant life events leave a lasting impression in memory.     

论儒家大同思想对毛泽东设计中国社会模式的影响

儒家大同思想在中国二千年的政治文化中影响深远。毛泽东深受中国传统文化影响。其中儒家大同思想的影响尤其巨大。这种影响渗透在其政治思维中,成为他日后设计中国社会模式的重要文化基因。毛泽东设计的具有儒家大同思想和空想社会主义色彩的社会模式,在中国的实践中由于严重脱离实际和生产力发展水平,耗费了大量的社会资本,使中国的现代化进程遭遇重大挫折。     

Women’s occupational career patterns over 27 years: Relations to family of origin, life careers, and wellness

This study aimed at identifying and describing occupational career patterns (OCPs) from age 16 to 43 by applying optimal matching techniques to sequence data obtained from a sample of Swedish women. Women’s occupational trajectories were found to be diverse. Upward mobility (3 patterns) and stable careers (4 patterns) were prevalent, but there were also women characterized by downward mobility, fluctuation and being outside the labor market (1 pattern each). Women’s OCPs were related to family of origin, but more strongly to their overall life career (i.e., multiple role constellations over the life course). The study indicates that occupational mobility patterns do matter in terms of job perceptions, work attitudes, and quality of life. The results generally confirm the popular belief of the advantage of upward mobility, followed by stable occupational careers, whereas women with downward or fluctuating careers fared worst.     

场景知觉及其研究范式

场景知觉关注的是人如何知觉和加工复杂的真实环境信息。场景包括物体和背景两个重要的组成部分,根据复杂性与真实性程度,场景刺激材料可以分为三种不同的类型。已有研究主要从自上而下和自下而上两种方式来解释场景知觉中信息的提取和加工,也有研究试图从二者交互的角度来进行解释。此外,基于不同的实验目的和技术,研究者分别采用了眼动、背景提示、物体觉察、变化觉察和点线索追随几种不同的研究范式来探讨场景信息的知觉问题。场景知觉研究在场景的定义、不同范式间的整合、研究内部效度和不同加工阶段的加工方式四个方面还需要进一步深入和探讨     

BEAUTY IN THE LIVING WORLD

Almost all admit that there is beauty in the natural world. Many suspect that such beauty is more than an adornment of nature. Few in our contemporary world suggest that this beauty is an empirical principle of the natural world itself and instead relegate beauty to the eye and mind of the beholder. Guided by theological and scientific insight, the authors propose that such exclusion is no longer tenable, at least in the data of modern biology and in our view of the natural world in general. More important, we believe an empirical aesthetics exists that can help guide experimental design and development of computational models in biology. Moreover, because theology and science can both contribute toward and equally profit from such an aesthetics, we propose that this empirical aesthetics provides the foundation for a living synergy between theology and science.     

An empirical and computational investigation of perceiving and remembering event temporal relations

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.     

时序信息和空间信息在工作记忆中的分离存储

采用相对新近性判断范式（judgments of relative recency）,通过三个实验探讨了工作记忆中时序信息和空间信息的存储方式及其关系。实验一比较了有无空间线索两种条件下时序信息的记忆绩效,结果发现,有无空间线索并不影响对时序信．E-的记忆。实验二和实验三通过控制刺激呈现的视野范围和减少呈现位置的不确定性来利化空间线索,结果表明,时序信息的记忆绩效也不受空间线索的影响。由此推论,工作记忆中的时序信息和空间信息是分离编码存储的,加入空间线索并不能提高时序信息的记忆绩效。
