急性心肌梗死中医治疗的两点策略——附临床资料回顾性分析

急性心肌梗死(AMI)是临床常见的急重症,现代医学已在循证医学基础上建立了诊疗指南,为临床诊治决策提供依据.相比而言.以辨证论治为特色的中医药缺乏循证依据.对AMI诊治过程中如何发挥中医药治疗的价值,认为不能停留在传统的概念上,应选择正确治疗策略,提高疗效.     

LOGICAL PLURALISM AND SEMANTIC INFORMATION

Up to now theories of semantic information have implicitly relied on logical monism, or the view that there is one true logic. The latter position has been explicitly challenged by logical pluralists. Adopting an unbiased attitude in the philosophy of information, we take a suggestion from Beall and Restall at heart and exploit logical pluralism to recognise another kind of pluralism. The latter is called informational pluralism, a thesis whose implications for a theory of semantic information we explore.

Interaction between locale and taxon strategies in human spatial learning

Three computer-based experiments which tested human participants in a non-immersive virtual watermaze task sought to determine factors which dictate whether the presence of a visual platform disrupts locale learning and taxon learning. In Experiment 1, the visible platform disrupted locale but not taxon learning based on viewpoint-independent and viewpoint-dependent information, respectively. In Experiment 2, taxon learning based on non-geometric cues providing viewpoint-dependent information was disrupted by the visible platform when the cues required relational information to disambiguate them from other cues. Experiment 3 placed participants in an isosceles triangular pool. The presence of the visible platform did not disrupt the encoding of relational information provided by shape of the pool. These results support the notion that geometric cues are encoded in a separate module which is impenetrable to non-geometric cues not creating the shape of the environment.     

8—12岁超常与常态儿童的检测时比较

研究者采用两种视觉检测时任务,比较了8至12岁超常和常态儿童的检测时发展变化特点。结果发现：随着年龄的增长,超常组和常态组儿童的检测时都呈现出逐步减小的趋势,并且对于不同任务的检测时,两组儿童的发展速度不同,但均未表现出性别差异;在不同的年龄段和检测时任务中,超常组儿童的检测时均显著地快于常态组儿童。通过对两组儿童的检测时发展速率的比较还发现,儿童的检测时发展基本上不受学校知识或经验的影响。另外,两组儿童的检测时和智力测验分数之间都有中等程度的负相关。     

文本阅读中情境模型空间维度的非线索更新

采用实时窗口阅读技术,探讨文本阅读中不同研究范式下空间信息更新的特点。结果表明,阅读中情境模型空间信息的非线索实时更新是存在的,但要实现这种更新则需要一定的条件。相对于自动呈现材料,在更为自由的手动阅读条件下,先前阅读的空间信息,尤其是外显的位置信息（如“广场”）能够进行非线索的实时更新（实验一、实验二）;此外,实验三的结果表明,不同的探测位置对空间信息的通达也产生了影响。在更为敏感的探测位置上,内隐的空间实体信息（如,“雕像”）也表现出了非线索的更新。     

因果力比较范式下对效力PC理论的检验

在用图形方式集中呈现信息的条件下,用因果力大小比较的实验范式检验效力PC理论。233名大学生被试对不同化学药物影响动物基因变异的能力做大小比较判断。结果发现,对单一因果关系因果力大小的比较判断具有以下3个特点：（1）不对称性：在预防原因条件下的因果力判断一般符合效力PC理论,而在产生原因条件下的因果力判断一般不符合效力PC理论;（2）在同时变化协变值DP和结果基率P(E|~C)的产生原因条件下,多数被试使用DP规则。这与概率对比模型的预测相一致,而不支持效力PC理论;（3）在固定协变值DP而只变化结果基率P(E|~C)的产生原因条件下,多数被试使用变异比RP规则。这是目前所有的因果推理理论都不能解释的现象。     

心理战信息损伤的概念与研究

信息是心理战进攻的主要武器,以造成心理杀伤为最终目标。为了更好地研究心理战防御,需要首先对信息损伤的特点进行研究。本文通过“非典”流行期间信息损伤的调查,界定了信息损伤的概念,总结了信息损伤的特点,分析了信息损伤的影响因素,提出了未来信息损伤的研究方向     

应用项目反应理论对《中国士兵人格问卷》的项目分析

采用项目反应理论（IRT）对《中国士兵人格问卷》进行项目分析。计算机呈现中国士兵人格问卷（CSPQ）对100,523名适龄男性青年进行测验,随机抽取2676名任一维度标准分均低于70的定为合格组;将任一维度大于70分并经专业人员访谈不合格的274名定为不合格组;从精神病院抽取男性年龄相当的221名缓解期精神分裂症患者定为精神病组,并完成CSPQ测验。运用基于IRT的双参数Logistic模型进行分析;结果发现,区分度参数超过区间(0.30,4.00)的条目删除前后,被试的能力值与标准分均存在显著相关;精神病组的测验分数经IRT分析,图形曲线与不合格组有高度吻合。研究结果说明,在测验精度基本相同的条件下,应用IRT可以减少施测条目,提高测验效率,可在一定程度上更精确地区分被试的特质水平     

The “identified victim” effect: an identified group,or just a single individual?

People's greater willingness to help identified victims, relative to non‐identified ones, was examined by varying the singularity of the victim (single vs. a group of eight individuals), and the availability of individually identifying information (the main difference being the inclusion of a picture in the “identified” versions). Results support the proposal that the “identified victim” effect is largely restricted to situations with a single victim: the identified single victim elicited considerably more contributions than the non‐identified single victim, while the identification of the individual group members had essentially no effect on willingness to contribute. Participants also report experiencing distress when the victim is single and identified more than in any other condition. Hence, the emotional reaction to the victims appears to be a major source of the effect. Copyright © 2005 John Wiley & Sons, Ltd.     

移情对亲社会行为决策的两种功能

移情对亲社会行为决策具有动机功能和信息功能。霍夫曼认为,移情忧伤不仅能够作为亲社会道德动机促进亲社会行为的产生,而且能够激活观察者的道德原则,进而引发亲社会行为。巴特森强调移情不仅能够增强解除他人困境的动机,而且带有重视他人福利和想使他人困境得到解除的程度的信息。移情的动机功能依赖于诱发移情的情境,而信息功能具有稳定的倾向性,比动机功能更持久,两种功能共同作用使移情在亲社会行为决策中具有更强的适应性。移情功能理论对道德教育具有启示作用。
