Noise,Economy, and the Emergence of Information Structure in a Laboratory Language

The acceptability of sentences in natural language is constrained not only grammaticality, but also by the relationship between what is being conveyed and such factors as context and the beliefs of interlocutors. In many languages the critical element in a sentence (its focus) must be given grammatical prominence. There are different accounts of the nature of focus marking. Some researchers treat it as the grammatical realization of a potentially arbitrary feature of universal grammar and do not provide an explicit account of its origins; others have argued, however, that focus marking is a (grammaticalized) functional solution to the problem of efficiently transmitting information via a noisy channel. By adding redundancy to highlight critical elements in particular, focus protects key parts of the message from noise. If this information‐theoretic account is true, then we should expect focus‐like behavior to emerge even in non‐linguistic communication systems given sufficient noise and pressures for efficiency. We tested this in an experiment in which participants played a simple communication game in which they had to click cells on a grid to communicate one of two line figures drawn across the grid. We manipulated the noise, available time, and required effort, and measured patterns of redundancy. Because the lines in many cases overlapped, meaning that only some parts of each line could be used to distinguish it from the other, we were able to compare the extent to which effort was expended on adding redundancy to critical (non‐overlapping) and non‐critical (overlapping) parts of the message. The results supported the information‐theoretic account of focus and shed light on the emergence of information structure in language.     

On Fodor's First Law of the Nonexistence of Cognitive Science

In his enormously influential The Modularity of Mind, Jerry Fodor (1983) proposed that the mind was divided into input modules and central processes. Much subsequent research focused on the modules and whether processes like speech perception or spatial vision are truly modular. Much less attention has been given to Fodor's writing on the central processes, what would today be called higher‐level cognition. In “Fodor's First Law of the Nonexistence of Cognitive Science,” he argued that central processes are “bad candidates for scientific study” and would resist attempts at empirical analysis. This essay evaluates his argument for this remarkable claim, concluding that although central processes may well be “messier” than input modules, this does not mean that they cannot be studied and understood. The article briefly reviews the scientific progress made in understanding central processes in the 35 years since the book was published, showing that Fodor's prediction is clearly falsified by massive advances in topics like decision making and analogy. The essay concludes that Fodor's Law was not based on a clear argument for why the complexities of central systems could not be studied but was likely based on intuitions and preferences that were common in psychology at the time.     

基于公益性的公立医院理事会型治理模式的构建

新医改方案明确强调公立医院回归公益性,并提出建立和完善医院法人治理结构。公立医院法人治理改革必须确保和强化其公益性特点,并在此基础上尝试构建我国公立医院理事会型治理模式的基本框架,以期得出有助于推进我国公立医院法人治理结构改革的结论及建议。分析了公立医院内部治理的核心,即建立权力、责任与利益相互制衡的机制;以及独立理事制度、有效的市场竞争机制、信息披露机制和社会监督体系等公益性的外部保障。构建公立医院理事会型治理模式必须完善医院内外部治理结构与机制,同时要有相应的政策法规配套。     

美国高等临床药学教育体系宏观结构变迁研究（1965年～2015年）

研究了1965年~2015年美国高等临床药学教育体系的层次结构、形式结构和分布结构等宏观结构的变迁情况。从临床药学实践、药师动态短缺、产业结构基础、办学经费来源、人口地理分布等方面,对半个世纪以来美国临床药学教育体系宏观结构变迁情况进行归因分析。在总结并肯定美国高等临床药学教育体系极高的市场敏感性和较强的结构优化灵活性的同时,探讨了美国高等临床药学教育体系宏观结构变迁过程中需要注意的问题。     

中医隐性知识结构维度模型的验证性研究

隐性知识大量存在于中医医者知识体系中。深入探讨中医医者隐性知识的结构维度,有利于中医的传承及个体隐性知识的转移。通过文献分析和专家访谈,发现中医隐性知识可以分为学习策略维度、临床技能维度、人际互动维度、情绪情感维度、价值取向维度和中医药文化维度。结合各维度之间的相互关系,构建了中医隐性知识的结构模型。为了提升该维度结构模型的科学性,对国家级名老中医、国医大师、中医院管理者进行了深度访谈和问卷调查,进行了验证性研究。     

时间间隔与未来事件效价：解释水平的中介作用

通过考察解释水平, 诠释时间间隔和未来事件效价的双向关系。结果发现：时间间隔会影响人们对未来事件效价的感知, 高解释水平事件在长时间间隔后发生的感知效价更好, 而低解释水平事件在短时间间隔后发生的感知效价更好(研究1); 同时, 未来事件效价也会反向影响人们对时间间隔的感知, 相对于未来发生的正效价事件, 负效价事件的感知时间间隔更短(研究2)。无论是时间间隔对未来事件感知效价的影响, 还是未来事件效价对感知时间间隔的影响, 解释水平均在其中起到中介作用。     

中国人人格特质结构对合作的影响机制

采用调整后的公共财物范式,将合作分为内部准备阶段（合作意识）和外部表现阶段（合作行为）,以中国人人格问卷（QZPS）为工具,研究人格特质结构对合作不同阶段的影响机制。结果表明,（1）在合作的不同阶段,产生影响作用的人格特质因素不同。中国人人格特质中的善良和情绪性直接影响合作意识,行事风格与人际关系因素直接影响合作行为,外向性通过调节合作意识与合作行为的关系影响合作行为。（2）在考虑合作意识与人格特质交互作用的模型能够更好的解释和预测合作行为。文中讨论了在研究合作过程时从个体内部因素、特质以及外部情境等多角     

Dispositional and comparative optimism interact to predict avoidance of a looming health threat

Research indicates that when confronted with a health threat, individuals high in both dispositional and comparative optimism employ a more avoidant style of coping than individuals high in dispositional but low in comparative optimism. We examined the hypothesis that threat distance moderates this interactive optimism association. In two studies, participants were randomly assigned to a looming or distant threat condition. Study 1 revealed that in the looming threat condition, participants high in both forms of optimism were more likely to minimise the threat and less inclined to seek additional health information relative to participants high in dispositional but low in comparative optimism. In Study 2, the same interaction pattern emerged on a measure of psychological abstraction suggesting these variables combine to alter broad information processing strategies. Implications for considering multiple forms of optimism when delivering health status information are discussed.     

Psychometric properties and factor structure of the Fear Questionnaire phobia subscale items in two normative samples

Normative data for the Fear Questionnaire (Marks & Mathews, 1979), a popular self-report instrument measuring phobic concerns, were collected from both a community and a collegiate sample. The covariation and internal consistency of the blood-injury phobia (BI), social phobia (SO), and agoraphobia (AG) subscales were assessed in each sample, and the factor structure of the items from these three subscales was examined. Results indicated that, in general, community subjects reported more phobic concerns than did collegiate subjects, and females reported greater phobic concerns than did males. Results from confirmatory factor analyses suggest that the three factors of BI, SO, and AG did not emerge from either data set. Follow-up exploratory factor analyses did identify the general factors of blood-injury phobia and agoraphobia. Normative data from the present study are compared to those obtained previously, and directions for future research are provided.
