认知闭合需要研究评述

认知闭合需要是个体稳定的认知特征,描述了个体在面对模糊情境时是否愿意系统处理信息的动机。已有研究表明,认知闭合需要对个体的信息处理过程和决策结果有显著的预测能力。总体上说,高认知闭合需要的个体更容易利用启发式进行思考,因此此类个体更容易受到过度归因、首因效应等的影响。虽然大多数的研究表明认知闭合需要是个体稳定的认知特质,但也有研究者发现环境因素如噪音等可以在一定程度上、在短时期内改变个体的认知闭合需要的水平。因此,在相关研究中,认知闭合需要既可以通过量表测量,也可以通过在实验中改变环境噪音和时间压力等方法来操纵。已有的关于认知闭合需要的研究也有不足之处。首先,如何引导高认知闭合者克服匆忙做出决策的动机并采用分析式的方式处理信息和进行决策,目前的相关研究还很少;其次,已有的关于认知闭合的研究大都为实验室研究,因此这些研究的外部效度较低;第三,认知闭合需要在冲突研究领域的应用被忽略了。未来有必要针对这些不足之处进行相应研究     

记叙文中时间信息的事件边界效应

运用视知觉研究中经典的事件切割程序,探讨记叙文中时间信息的事件边界效应.结果发现记叙文中的时间信息会被读者外显地知觉为事件边界,并且,跨度长的时间信息比跨度短的时间信息更易于被知觉为事件边界.这和视知觉研究中的发现是一致的.研究在一定程度上支持了记叙文理解过程中情境模型建构的过程依赖类似于事件知觉中所发现的切割过程的观点,为知觉研究和认知研究领域提供了可供沟通的实证支持.     

自省主体对Moore-型信息的处理与融合

The main task is to discuss the issue in belief dynamics in which philosophical beliefs and rational introspective agents incorporate Moorean type new information. First, a brief survey is conducted on Moore’s Paradox, and one of its solutions is introduced with the help of Update Semantics. Then, we present a Dynamic Doxastic Logic (DDL) which revises the belief of introspective agents put forward by Lindström &; Rabinowicz. Next, we attempt to incorporate Moorean type new information within the DEL (DDL) framework, as advised by van Benthem, Segerberg et al. Though we maintain the principle of “the primacy of new information” from the literature on traditional belief revision theory, several unsuccessful ways are also presented. We then conclude that some special kind of success (weak success) can still be found in those revision processes although absolute success does not hold. At last, the relevant problem of “learnability” is re-considered through weak success.     

重复启动对时序知觉的影响

在时序判断任务中,重复启动导致被试把启动的靶刺激知觉为先出现的。知觉加工增强观和决策反应偏向观都试图解释其机制,但仍存在争议。本研究采用图形材料,通过三个实验系统考察了重复启动对时序知觉的影响。实验结果显示,启动和指导语都具有显著效应。这说明,重复启动对时序知觉的影响涉及知觉加工和决策水平两个方面。实验还首次发现,在启动的靶刺激先出现时发生了重复启动效应的反转。最后,研究提出了双加工表征匹配调节假说,用以综合解释目前的研究结果     

文本阅读中协调性整合的发生机制

采用移动窗口技术和自我报告法探讨了文本阅读中协调性整合发生的具体机制。被试为华南师范大学本科生114名。实验1通过分析不同条件下目标句的阅读时间探讨当前信息跟先前信息只有语义相关上的局部不一致但没有事件相关时能否发生协调性整合。实验2通过分析不同条件下探测词的反应时间探讨文本阅读过程中单纯语义相关没有事件相关时,目标句阅读是否会自动激活跟其有关的背景信息。实验3通过分析不同条件下目标句的阅读时间和被试的自我报告指标探讨协调性整合是否是一种自动化的过程,即探讨被试在文本阅读过程中能否意识到这种信息整合方式。总的实验结果表明,文本阅读中当前信息跟先前信息有语义相关时可以引发信息激活,但只有当前信息跟先前信息有事件相关时才会发生信息整合;另外,协调性整合是一种自动化的过程,读者在文本阅读过程中不能意识到这种信息整合方式的发生     

跨通道的优先登录现象

优先登录现象是指注意所投向的客体或通道能够更快地进入我们的意识之中,是注意的一个重要时间特性。本文首先介绍了三种主要的研究方法（时序判断范式、同步判断范式和线运动错觉范式）,并比较了三者之间的差异。然后,回顾了跨通道优先登录现象的研究历史,根据围绕优先登录现象的历史争论,归纳出各种影响优先登录效应的因素（包括眼动、刺激的相对强度、刺激的相对空间位置和反应偏向）。最后,对未来跨通道优先登录的研究进行了展望。     

The Use of Verb Information in Parsing: Different Statistical Analyses Lead to Contradictory Conclusions

The research investigated how comprehenders use verb information during syntactic parsing. Two reading experiments investigated the relationship between verb-specific variables and reading time. These experiments were close replications of prior work; however, two statistical techniques were used, rather than one. These were item-by-item correlations and participant-by-participant regression. In Experiment 1, reading time was measured using a self-paced moving window. In Experiment 2, eye movements were recorded during reading. The results of both experiments showed that the results of two types of statistical analyses support contradictory conclusions. The analyses involving participant-by-participant regression analyses provided no evidence for the early use of verb information in parsing and support syntax-first approaches to parsing. In contrast, the results of item-by-item correlation were consistent with the prior research, supporting the view that verb information can guide initial parsing decisions. Implications for theories of parsing are discussed. This research was financially supported by Grants HD-07327 and HD-18708 awarded to the University of Massachusetts at Amherst and supported by a grant awarded to the author by the National Science Foundation (BCS 0446998).     

Cognitive consequences of novelty and familiarity: How mere exposure influences level of construal

Two experiments examine whether frequency of exposure influences level of construal. Using subliminal presentation, participants were exposed to neutral, unknown letters 0, 5, 15, or 40 times, and a typical mere exposure effect was found on evaluation. However, we hypothesized and showed in Experiment 1 that novelty enhances Gestalt-like, global perception, whereas familiarity bolsters detail-oriented, local perception. Furthermore, in Experiment 2, we demonstrated that participants generated more abstract solutions for items presented less frequently. These results support a Construal level theory [Liberman, N., Trope, Y., & Stephan, E. (2007). Psychological distance. In E. T. Higgins & A. W. Kruglanski, Social psychology, handbook of basic principles. New York: Guilford Press.] contention that distance from direct experience is associated with high construal level and global processing. It seems that in order to prepare for novel events, people automatically engage in higher levels of construal. New information needs to be integrated into existing knowledge structures in order to be understood, and abstract categories and global processing may support the process of understanding.     

Logical information and epistemic space

Gaining information can be modelled as a narrowing of epistemic space. Intuitively, becoming informed that such-and-such is the case rules out certain scenarios or would-be possibilities. Chalmers’s account of epistemic space treats it as a space of a priori possibility and so has trouble in dealing with the information which we intuitively feel can be gained from logical inference. I propose a more inclusive notion of epistemic space, based on Priest’s notion of open worlds yet which contains only those epistemic scenarios which are not obviously impossible. Whether something is obvious is not always a determinate matter and so the resulting picture is of an epistemic space with fuzzy boundaries.     

The medium can influence the message: Print-based versus digital reading influences how people process different types of written information

While electronic reading devices are extremely popular, research is equivocal regarding their benefits for outcomes such as reader comprehension. Integrating literatures on reading medium comparisons and matching effects in persuasion, this research tested whether comprehension is maximized when the content of the material (e.g., whether it is traditional vs. modern) matches the medium (e.g., reading from a traditional book vs. digital e-reader). In Study 1, participants read a traditional- or modern-themed short story from either a book or an e-reader. Story comprehension was greater when participants read from the printed medium compared to the e-reader, an effect that was marginally moderated by story content, consistent with a matching effect. In Study 2, participants read a persuasive message that emphasized either a traditional versus modern solution to improving health in either a magazine format or on an iPad. Message comprehension was marginally greater among participants who read their message in a printed format. Participants’ interest in weight loss showed evidence of a matching effect – participants were more interested in losing weight when a modern solution to obesity article was presented on an iPad compared to a printed format. The results are applied to the study of reading and attitude change.
