通过文献检索、走访调研并结合笔者时美国教学医院门诊病历管理的实地考察,本文对中美两国教学医院人员对门诊病历管理的认识理念、门诊病历管理的方式、病历的规范设计以及门诊病历的质量控制等方面进行了对比研究.显示我国教学医院在门诊病历管理方面与发达国家存在着差距.从提高临床医疗和医学教学质量、有利于患者疾病的诊治和培养当代优秀医务工作者,促进医学科学技术发展出发,教学医院管理者和临床指导医生应高度重视和规范门诊病历管理. 相似文献

品牌不安全感是指消费者对某品牌存在潜在或现实威胁的主观感知和担忧。以往文献中, 与品牌不安全感有关的研究主要隐含在两个领域:一是以产品伤害危机为中心的品牌心智变化研究; 二是以企业伦理责任为中心的品牌心智变化研究。但这两个领域都尚未揭示消费者品牌不安全感的实质、心理表征、危害机制和预警功能等。品牌不安全感是消费者回避或拒绝某品牌的心理根源之一。因此基于产品伤害事件频发的事实和品牌心智理论, 有必要对品牌不安全感作系统研究, 具体探索品牌不安全感的本质内涵、导致品牌不安全感的威胁源、品牌不安全感的心理表征、危害机制、预防和化解策略、以及品牌心理安全管理理论等问题。 相似文献

成人后期日常能力自评与操作水平的横断比较 总被引:1,自引:0,他引:1
采用自我评估与纸笔操作相结合的方法 ,对 2 3 3名 55至 74岁的成人后期被试完成七项日常活动的能力进行横断比较。结果表明 :自评能力与操作能力既存在一定的一致性 ,也存在相当大的差异性 ,各活动项目上的自评水平比操作水平要高 ;操作水平表现出随年龄增长而下降的趋势 ,从 70岁开始下降最为明显 ,而自评水平未呈现出这种变化特点 ;不同活动领域上的操作水平存在不同的发展轨迹 ;在少数活动领域具有显著的性别差异 相似文献

Long-term potentiation (LTP) shares many properties with memory and is currently the most popular laboratory model of memory. Although it has not been proven that memory is based on an LTP-like mechanism, there is evidence that learning a motor skill can induce LTP-like effects. This evidence was obtained in a slice-preparation experiment, which precluded within-animal comparisons before and after training. In the present experiments, Long-Evans rats were unilaterally trained to acquire a forelimb reaching and grasping skill. Evoked potentials were found to be larger in motor cortex layer II/III in the trained, compared to the untrained, hemisphere in slice, acute, and chronic preparations. Consistent with previous research, the trained hemisphere was less amenable to subsequent LTP induction. Furthermore, the application of either LTP- or LTD-inducing stimulation during the training phase of the reaching task disrupted the acquisition of the skill, providing further evidence that memory may be based on an LTP mechanism. 相似文献

Is it culture or is it language? Examination of language effects in cross-cultural research on categorization 总被引:2,自引:0,他引:2
Differences in reasoning styles between Chinese and European Americans held even when controlling for the language of testing. Bilingual Chinese organized objects in a more relational and less categorical way than European Americans, whether tested in English or in Chinese. Thus, culture affects categorization independent of the testing language. Nevertheless, language affected some Chinese bilinguals' categorization. The responses of Chinese from the Mainland and Taiwan were more relational when tested in Chinese than when tested in English. Responses of Chinese from Hong Kong and Singapore were equally relational when tested in Chinese and in English. Age and context of learning English are discussed to explain the differential language effects among different Chinese groups. Theoretical and methodological implications are discussed. 相似文献

East Asian cognition has been held to be relatively holistic; that is, attention is paid to the field as a whole. Western cognition, in contrast, has been held to be object focused and control oriented. In this study East Asians (mostly Chinese) and Americans were compared on detection of covariation and field dependence. The results showed the following: (a) Chinese participants reported stronger association between events, were more responsive to differences in covariation, and were more confident about their covariation judgments; (b) these cultural differences disappeared when participants believed they had some control over the covariation judgment task; (c) American participants made fewer mistakes on the Rod-and-Frame Test, indicating that they were less field dependent; (d) American performance and confidence, but not that of Asians, increased when participants were given manual control of the test. Possible origins of the perceptual differences are discussed. 相似文献

Positive risk-taking is a crucial element of individual creativity and social development. However, little is known regarding the relation between individual neural differences and positive risk-taking. In addition, critical thinking (CT) and gender have been proven to be two important individual-specific factors associated with risk-taking behaviour, and different levels of CT and gender may have diverse effects on the relationship between brain structure and positive risk-taking. The present study examined the relationship between positive risk-taking and regional grey matter volume (rGMV) in 292 healthy participants. The results showed that positive risk-taking was significantly positively associated with the rGMV of the posterior cingulate cortex (PCC). In addition, this study investigated individual differences in critical thinking and found that it moderated the relationship between rGMV and positive risk-taking. Individuals with lower CT had a stronger association between rGMV and positive risk-taking. Further analysis showed that for males, a greater rGMV was significantly linked to higher positive risk-taking tendency. These findings suggest that PCC evaluates risk and serves as a behavioural adaptation hub for positive risk-taking. This study thereby contributes to the literature on individual differences in brain structure and risk-taking by elucidating the moderating effects of CT and gender in healthy adults. 相似文献

语义的自动加工和选择性注意对Stroop效应的影响 总被引:3,自引:1,他引:2
本实验用正常人和聋哑人作被试进行比较,试图探讨语义的自动加工和选择性注意对Stroop效应的影响。将“红”“绿”“黄”“蓝”四个汉字中的每一个都用这四种颜色中的三种写成,然后按着事先排列好的顺序,分组呈现,并且在两种条件下分别要求被试延迟不同的时间进行反应,一种是刺激呈现前就告诉被试对“字”或“色”反应;另一种是刺激呈现后间隔不同的时间再向被试提出对“字”或“色”反应。实验结果发现,聋哑人和正常人在色—字干扰任务作业上没有明显的差异,说明语义的自动加工是一个普遍现象;而选择性注意能在很大的程度上改善被试的作业成绩,但颜色命名仍比字词反应困难;Stroop效应在延迟反应条件下发生变化,这种变化说明Stroop效应与记忆过程有联系。 相似文献

从汉字识别看视觉信息检测的整体优先性 总被引:4,自引:0,他引:4
本实验以汉字组成的复合汉字为材料研究了不同视角下辨别整体结构和辨别局部特性的反应时差异。实验发现,在正常情况下对整体的辨别反应时要显著低于对局部进行辨别的反应时,并且对象的不同大小对这种差异没有显著影响。这一结果表明整体和局部的“相对大小”不是造成反应时差异的主要原因,提示视觉信息检测是一个从大范围的整体到局部的过程,即存在整体优先性。实验还发现在作为局部的汉字和构成整体的复合字相同时,无论注意对象是局部还是整体,反应时均较不同时为小,这一结果表明整体和局部的作用是双向的。 相似文献
