国内医疗保障研究的知识图谱分析——基于CNKI数据库（2005年～2016年）

系统展现国内医疗保障领域的研究热点、重要学者、科研合作关系、期刊情况,对医疗保障研究形成直观的印象。利用可视化软件CiteSpace和文献计量学方法从关键词、作者、研究机构、期刊等方面进行知识图谱分析。分析结果表明,已有的医疗保障领域研究集中在新农合、医改、商业医疗保险参与社会保险、弱势群体和农民工医疗保障五类研究主题;出现了商业医疗保险、城乡统筹、大病保险等新的研究领域;学者之间的研究比较独立,少有稳定的研究团队,缺乏交流和资源共享。     

The interrelatedness between infants’ communicative gestures and lexicon size: A longitudinal study

Research has shown a close relationship between gestures and language development. In this study, we investigate the cross-lagged relationships between different types of gestures and two lexicon dimensions: number of words produced and comprehended. Information about gestures and lexical development was collected from 48 typically developing infants when these were aged 0;9, 1;0 and 1;3. The European Portuguese version of the MacArthur–Bates Communicative Development Inventory: Words and Gestures (PT CDI:WG) was used. The results indicated that the total number of actions and gestures and the number of early gestures produced at 0;9 and at 1;0 year predicted the number of words comprehended three months later. Actions and gestures’ predictive power of the number of words produced was limited to the 0;9–1;0 year interval. The opposite relationship was not found: word comprehension and production did not predict action and gestures three months later. These results highlight the importance of non-verbal communicative behavior in language development.     

大学生知识价值观的实证研究

该研究从理论上界定了知识价值观及其基本成分(即知识价值目标、知识价值评价和知识价值手段)。运用设计的《大学生知识价值观调查表》,对2043名大学生进行了调查。结果显示,大学生在知识价值目标、知识价值评价和知识价值手段三方面都呈现出年级、性别和专业的差异。     

表征变化及其影响因素的微观发生研究

Karmiloff-Smith的表征重述理论认为表征重述是人类获取知识的重要途径,并且表征变化的过程包括程序、元程序和概念化三个阶段。采用微观发生法（包括前测、练习和迁移3个阶段,共8个期间）,以数字分解组合任务为研究材料,探讨了120名小学一、二年级儿童问题解决中的表征变化及所受年龄和练习模式等因素的影响。结果表明,前测中存在发展性差异,即二年级儿童达到概念化阶段的人数显著多于一年级儿童,但前测处于程序阶段的儿童接受5次解题练习过程中以及在近迁移题目上都没有表现出年级差异,而在远迁移题目上二年级儿童的完成情况好于一年级儿童。练习模式对表征变化的影响主要体现在三个方面：（1）从变化的路线看,与简单模式相比,复杂模式更能促进儿童的表征发生变化,而且这时儿童表征变化的路线更丰富,表征变化发生循环的人数比例也更高。（2）从变化的速度看,复杂模式下儿童在插入难题的两次练习期间表征变化比较迅速,其余期间变化较小;简单模式下儿童在第二次和第三次练习期间表征变化比较迅速,随后变化比较平稳。（3）从变化的广度看,练习中所获表征能力（在最后三次练习中达到元程序或概念化阶段）的推广,无论是在近迁移题还是远迁移题上两种练习模式之下的被试没有明显差异;但两组被试在近迁移题上的表现均好于远迁移题     

The impact of L1 structural frequency and cognate status on the timing of L2 production

The present study investigates the impact of first language (L1) structural frequency and L1 lexical accessibility, manipulated via cognate status, on second language (L2) speech production. L1 German–L2 English speakers and L1 English speakers completed a production task containing pre- and post-modified possessive noun phrase (NP) constructions (e.g. The actress’s sofa vs. The sofa of the actress) in which the head nouns were English-German cognates (e.g. sofa) or noncognates. While English prefers pre-modified NPs, German has a strong frequency bias for post-modified NPs. L2 English speakers exhibited higher production accuracy than L1 English speakers on post-modified NP sentences. However, facilitative L1 effects in production latencies were restricted to post-modified NP sentences containing cognates and only developed cumulatively after repeated exposure to post-modified NP sentences. We discuss how cognate status and L1 structural frequency differentially influence the accuracy and timing of choosing between different structural alternatives during L2 production.     

成人在错误信念任务上的表现

考察成人在错误信念(FB)任务上是否存在"知识偏差"效应。实验1重复Birch等的实验程序并未得到与之一致的结果,成人在FB任务上的表现不理想,且无"知识偏差"效应存在。实验2排除琴盒位置及颜色的突出性影响后,结果与实验1相似。成人在FB任务上的不佳表现与成人具有心理理论的事实相悖,说明把通过FB任务作为衡量心理理论的唯一评定标准有待商榷。     

Constituent Length Affects Prosody and Processing for a Dative NP Ambiguity in Korean

Two sentence processing experiments on a dative NP ambiguity in Korean demonstrate effects of phrase length on overt and implicit prosody. Both experiments controlled non-prosodic length factors by using long versus short proper names that occurred before the syntactically critical material. Experiment 1 found that long phrases induce different prosodic phrasing than short phrases in a read-aloud task and change the preferred interpretation of globally ambiguous sentences. It also showed that speakers who have been told of the ambiguity can provide significantly different prosody for the two interpretations, for both lengths. Experiment 2 verified that prosodic patterns found in first-pass pronunciations predict self-paced reading patterns for silent reading. The results extend the coverage of the Implicit Prosody Hypothesis [Fodor, J Psycholinguist Res 27:285–319, 1998; Prosodic disambiguation in silent reading. In M. Hirotani (Ed.), NELS 32 (pp. 113–132). Amherst, MA: GLSA Publications, 2002] to another construction and to Korean. They further indicate that strong syntactic biases can have rapid effects on the formulation of implicit prosody.     

How great apes perform on a modified trap-tube task

To date, neither primates nor birds have shown clear evidence of causal knowledge when attempting to solve the trap tube task. One factor that may have contributed to mask the knowledge that subjects may have about the task is that subjects were only allowed to push the reward away from them, which is a particularly difficult action for primates in certain problem solving situations. We presented five orangutans (Pongo pygmaeus), two chimpanzees (Pan troglodytes), two bonobos (Pan paniscus), and one gorilla (Gorilla gorilla) with a modified trap tube that allowed subjects to push or rake the reward with the tool. In two additional follow-up tests, we inverted the tube 180° rendering the trap nonfunctional and also presented subjects with the original task in which they were required to push the reward out of the tube. Results showed that all but one of the subjects preferred to rake the reward. Two orangutans and one chimpanzee (all of whom preferred to rake the reward), consistently avoided the trap only when it was functional but failed the original task. These findings suggest that some great apes may have some causal knowledge about the trap-tube task. Their success, however, depended on whether they were allowed to choose certain tool-using actions. Electronic Supplementary Material Supplementary material is available for this article at     

Principled and statistical connections in common sense conception

Nominal concepts represent things as tokens of types. We report six experiments that investigate the nature of the relations we represent between the type of thing something is (e.g. DOG) and its other properties. The experiments provide evidence that we represent principled connections between the type of thing something is (e.g. DOG) and some of its properties (k-properties; e.g. having four legs for dogs), but not other properties (t-properties; e.g. being brown for dogs). Principled connections are different from logical, statistical, and causal connections. Principled connections, (i) license the expectation that tokens of the type will generally possess the k-property, (ii) license explanation of the presence of k-properties in tokens of a type by reference to the type of thing it is, and (iii) license normative expectations concerning the presence of the k-property in tokens of the type. The experiments provide evidence for all three of these aspects of principled connections. The experiments also demonstrate that principled connections must be distinguished from merely strong statistical connections. We suggest that principled connections are one of the fundamental types of relations (in addition to logical, statistical, and causal relations) in terms of which our conceptual knowledge is structured. We argue that principled connections reveal a formal mode of understanding and explanation. This mode of understanding complements other modes of understanding that have been studied within the theory-based approach to conceptual representation. Finally, we suggest that kind representations are distinguished from representations of mere types by the representation of principled connections to k-properties.
