循证医学的兴起被认为是医学界重要的现代化运动,其哲学基础却一直倍受质疑。回顾了循证医学概念的发展和基本假设,整理了从认识论视角质疑循证医学的若干观点,着重介绍循证医学倡导者对循证医学认识论的基本看法,包括证据和知识的关系,观察到的、可观察的和不可观察的事实间的关系,正确地进行观察,指出循证医学不是全新的医学证据产生与运用理论,而是对多种科学推理规则的综合运用。循证医学是应客观需要而产生,因争议而不断自我完善,实现其迅速发展。  相似文献

HAROLD模型(Hemispheric Asymmetry Reduction in Older Adults)是指与年轻人相比,老年人在完成某些认知任务时大脑激活呈现出非对称性减弱的现象。该模型自提出以来就引发了很多质疑和研究,近几年来又有一系列的研究分别从不同角度提供了支持该模型的证据,它们包括记忆研究领域、抑制研究领域、语言认知研究领域、感觉动作研究领域和脑神经研究领域。同时也存在明显不支持该模型的研究证据,主要体现为对补偿说的批驳。通过对支持该模型和不支持该模型两方面脑成像研究成果的文献分析,发现HAROLD模型可能是一个任务特异性模型;除补偿说之外,还有其他可能的观点能够解释功能性脑成像的年龄差异;对脑激活定义的进一步明确化有助于澄清相关的争论  相似文献

以7~15岁儿童青少年为研究对象,考察加工速度和执行功能对流体智力的影响。研究结果表明,随着年龄的增长,感觉运动加工速度、知觉加工速度对流体智力从具有直接影响到只通过执行功能中的记忆更新成分产生间接影响,但这种影响存在年龄间的差异。在童年中期(7~9岁),知觉加工速度对流体智力不仅具有直接的预测作用,还通过记忆更新对其产生间接的影响。童年晚期(10~12岁),感觉运动加工速度和知觉加工速度不再对流体智力具有直接预测作用,都是通过记忆更新和抑制/转换合成成分间接对流体智力起作用。青春期(13~15岁),知觉加工速度对流体智力只通过记忆更新产生间接影响。  相似文献

Repeated administration of cognitive tests improves test performance, making it difficult for researchers to gauge the true extent of age-related cognitive decline. The authors examined this issue using data from the Rush Religious Orders Study and linear mixed-effects models. At annual intervals for up to 8 years, more than 800 older Catholic clergy members completed the same set of 19 cognitive tests from which previously established composite measures of cognitive domains were derived. Retest effects on some measures were substantial and continued to accumulate even after 8 annual test readministrations, but effects on other measures were minimal. Across cognitive measures, retest effects were not related to age, sex, or education. Individual differences in retest effects were substantial but not consistent across cognitive measures. The results suggest that retest-based improvement in cognitive test performance can be substantial and persistent.  相似文献

The authors compared the associations among perceived maternal socialization goals (self-development, filial piety, and collectivism), perceived maternal parenting styles (authoritative, authoritarian, and training), and the social-emotional adjustment (self-esteem, academic self-efficacy, and depression) between Chinese and European American young adults. The mediation processes in which socialization goals relate to young adults' adjustment outcomes through parenting styles were examined. Results showed that European American participants perceived higher maternal self-development socialization goals, whereas Chinese participants perceived higher maternal collectivism socialization goals as well as more authoritarian parenting. Cross-cultural similarities were found in the associations between perceived maternal authoritative parenting and socioemotional adjustment (e.g., higher self-esteem and higher academic self-efficacy) across the two cultural groups. However, perceived maternal authoritarian and training parenting styles were found only to be related to Chinese participants' adjustment (e.g., higher academic self-efficacy and lower depression). The mediation analyses showed that authoritative parenting significantly mediated the positive associations between the self-development and collectivism goal and socioemotional adjustment for both cultural groups. Additionally, training parenting significantly mediated the positive association between the filial piety goal and young adults' academic self-efficacy for the Chinese group only. Findings of this study highlight the importance of examining parental socialization goals in cross-cultural parenting research.  相似文献

This paper takes a conceptual look at cosmopolitanism and the related issue of what it means to be human in order to arrive at an alternative conceptual framework which is free from empiricist assumptions. With reference to a discussion on Homer’s Iliad, the author develops a ‘humanist’ model of discerning humanity. This model is then compared and contrasted with Martha Nussbaum’s version of cosmopolitanism. The notion of ‘aspect-seeing’ discussed by Wittgenstein in the second part of the Philosophical Investigations is also examined in order to shed light on what it involves to discern humanity. Finally, racism is discussed from the philosophical perspective elaborated in order to highlight its distinctive conceptual features. It is hoped that this paper can refocus our attention on important issues concerning the basis of what it means to see human beings as human beings.  相似文献

This study examined the relations between cultural values (i.e., individualism and collectivism) and aggression among 460 (234 girls) Chinese adolescents. Conflict level and social status insecurity were examined as potential explaining mechanisms for these relations. The results showed that adolescents' endorsement of collectivism was negatively related to their use of overt and relational aggression as reported by teachers and peers, whereas positive associations were found between the endorsement of individualism and adolescent aggression. Adolescents' conflict level and social status insecurity accounted for a significant part of these associations. Findings of this study demonstrate the importance of examining intracultural variations of cultural values in relation to adolescent aggression as well as the process variables in explaining the relations.

首词和尾词频率对高熟悉度成语识别的影响   总被引:1,自引:1,他引:0  
采用词汇判定法,考察首词频率和尾词频率对高熟悉度四字成语识别的影响。实验结果表明:(1)对高熟悉度成语的识别规律与多层聚类表征模型的观点比较吻合;(2)构成成语的成份词对成语表征有竞争和干扰作用,高频率成份词相对于低频率成份词,对成语表征的竞争和干扰作用较大。  相似文献
