基于自然语料的门诊会话分析

门诊会话是医患双方了解病情、分析病因、确定诊疗手段的最直接的对话方式.本文基于门诊会话的自然语料,对照以往的相关研究,分析了门诊会话中医生会话策略使用的特点以及医师、患者和语境互动的会话序列特征,旨在深化对医患互动过程的认知,进一步揭示现代中国医院语境中医患交流的社会文化符号特点.     

老年住院患者孤独及其与抑郁、焦虑情绪的相关研究

采用UCLA孤独量表和18项简明症状问卷（BSI-18）对487名老年住院患者的孤独、焦虑、抑郁情绪进行调查分析。结果显示,（1）老年住院患者存在不同程度的孤独感、抑郁和焦虑情绪,男性患者的躯体症状、抑郁情绪和焦虑情绪重于女性患者。高学历患者躯体症状、抑郁情绪和焦虑情绪轻于低学历患者,有配偶患者孤独感低于无配偶的老年患者。（2）老年住院患者的孤独感与躯体症状、抑郁、焦虑呈正相关,且焦虑和抑郁能显著预测老年住院患者的孤独感。     

形上与本体的相逢——中国形而上学建构的历史与问题

现代中国哲学形而上学建构经历了于中国哲学中寻找形而上学,认识到中国形而上学具有独特的形态和特别的文化意义,融会中西思想综合创新,反对中国形而上学观念等环节.现代中国哲学的"本体论"包含了两个有待进一步澄清的问题,一是中国思想中本有的道论是不是一种本体论?二是中国古代的本体论与西方哲学的本体论是什么关系?只有将中国本有的...     

Consistent and Variable Practice Conditions: Effects on Relative and Absolute Timing

The authors conducted the present experiments to resolve the discrepancy between studies in which relative-timing learning has been found to be enhanced by consistent practice conditions and contextual interference experiments in which relative-timing learning has been found to be enhanced more by random practice than by blocked practice. There were 40 participants in Experiment 1 and 48 in Experiment 2. The results of Experiment 1 extended previous findings: The learning of the relative-timing pattern was systematically enhanced by the degree to which the practice conditions promoted movement consistency (constant > blocked > serial > random). Experiment 2 provided evidence that the discrepancy between the relative-timing effects in the 2 groups of studies was a product of the way in which relative-timing goals and feedback were presented. When the feedback was presented as segment times, random practice resulted in generally more stable relative-timing patterns during acquisition than blocked practice did. Thus, in both experiments, the learning of the relative-timing pattern was enhanced by more stable relative-timing conditions during acquisition. Absolute-timing learning, as indexed by the transfer tests, was enhanced by serial or random practice as compared with constant or blocked practice, and was relatively unaffected by feedback conditions directed at the relative-timing pattern. In terms of motor programming theory, those findings are taken as additional evidence for the disassociation of memories supporting generalized motor program (GMP) performance, as indexed by relative timing, and parameter performance, as indexed by absolute timing.     

Auditory Model Enhances Relative-Timing Learning

In recent experiments (Q. Lai, C. H. Shea, & M. Little, 2000; C. H. Shea, G. Wulf, J. Park, & B. Gaunt, 2001), auditory models were found to be effective in enhancing relative-timing performance and learning in constant practice conditions. In the present experiment, the authors examined (a) whether an auditory model also enhances relative-timing learning in blocked and random practice conditions and (b) whether experience with the auditory model enhances participants' ability to produce the response by using different effector sequences. Participants (N = 48) were randomly assigned to 1 of 4 acquisition conditions in which an auditory model was or was not present and the practice schedule was blocked or random. In the acquisition phase, all participants alternately pressed 2 keys on a keyboard in an attempt to match 5 goal intervals. In the auditory model conditions, a sequence of tones was played before each acquisition trial. The tones represented the correct timing sequence for that trial. One retention and 3 effector-transfer tests without feedback were administered about 24 hr after the completion of acquisition. The results indicated that the auditory model enhanced relative-timing performance and learning independently of practice schedule. In addition, the auditory model enhanced relative timing on the effector-transfer tests, but absolute-timing performance and learning were not affected by the auditory model. Thus, relative timing was found to be effector independent but absolute timing was not.     

负性情绪抑制对社会决策行为的影响

利用心理生理实验法, 通过将情绪抑制操作引入最后通牒博弈实验范式, 探讨负性情绪抑制的主观情绪体验、生理反应及其对社会决策行为的影响。以40名大学生为被试, 采用MP150型16导生理记录仪记录皮肤电反应和心率。实验为2 (组别：情绪抑制组、自然观看组) × 2 (性别：男、女) × 2 (博弈对手：人、计算机) × 4 (分配方案：￥5：￥5、￥7：￥3、￥8：￥2、￥9：￥1)的混合设计, 其中组别和性别为被试间因素, 博弈对手和分配方案为被试内因素。结果发现：(1)对负性情绪进行抑制没有减少被试相应的主观体验, 情绪抑制使皮肤电反应性增强; (2)负性情绪抑制的主观体验和生理反应不存在性别差异; (3)在面对不公平的分配方案时, 情绪抑制组被试比自然观看组更倾向于拒绝接受。结果表明在最后通牒博弈中,情绪抑制影响回应者的行为反应,使他们更倾向于做出不理智的决策。     

中国当代医疗语言学研究综述

中国当代医疗语言学研究可分为两大方面,一是理论构建,二是具体研究。对于前者,学者初步建立了理论框架,但未能充分融合沟通学和语言学的理论,较少客观分析患者的语言特点和贡献,未能深入讨论相关的语用、社会、心理、认知等因素。从研究路径来说,具体研究又可分为语言学方法、医学视角和人文视角三个方面,各自有不同的特点和优势。中国当代医疗语言学研究在医疗语言互动的语旨、语场、语式以及理论基础等方面还存在较多值得开拓的空白和课题。

Laboratory Replication of Scientific Discovery Processes

Fourteen subjects were tape-recorded while they undertook to find a law to summarize numerical data they were given. The source of the data was not identified, nor were the variables labeled semantically. Unknown to the subjects, the data were measurements of the distances of the planets from the sun and the periods of their revolutions about it—equivalent to the data used by Johannes Kepler to discover his third law of planetary motion. Four of the 14 subjects discovered the same law as Kepler did (the period varies as the 3/2 power of the distance), and a fifth came very close to the answer. The subiects' protocols provide a detailed picture of the problem-solving searches they engaged in, which were mainly, but not exclusively, in the space of possible functions for fitting the data, and provide explanations as to why some succeeded and the others failed. The search heuristics used by the subjects are similar to those embodied in the BACON program, computer simulation of certain scientific discovery processes. The experiment demonstrates the feasibility of examining some of the processes of scientific discovery by recreating, in the laboratory, discovery situations of substantial historical relevance. It demonstrates also, that under conditions rather similar to those of the original discoverer, a law can be rediscovered by persons of ordinary intelligence (i.e., the intelligence needed for academic success in a good university). The data for the successful subjects reveal no “creative” processes in this kind of a discovery situation different from those that are regularly observed in all kinds of problem-solving settings.
