Paralympic Games (PG), involving people with disabilities (PWD), are a manifestation of excellence in sport. They show that athletics performed by PWD counts as genuine sport. They also support a wider meaning of the term ‘health,’ understood not just like a utopian state of perfection, but like the ability to realize oneself in the projects and activities of one’s own choosing. Notwithstanding these virtues, PG—in their current form—may paradoxycally reinforce social prejudice against PWD. This is due to the fact that PG and Olympic Games (OG) are now two distinct events. In this article, I argue that PG should be integrated in the OG, just like women’s and ‘minor’ sports, because the separation of PG and OG indicates a morally arbitrary separation between people with and without disabilities. I also propose to remove the word ‘Para-lympic’ because it stigmatizes the sport performed by PWD as an appendix of ‘normal’ sport. Athletes with disabilities deserve special attention because they have special needs; but they also deserve an arena where their excellence is offered to the public, and this arena should not be different from that of normal-bodied athletes. 相似文献

Rips’ (1989) results with the transformational paradigm have often been cited as supporting accounts of categorisation not based on similarity, such as involving necessary or sufficient features (or a belief in such features), which guarantee a categorisation outcome once their presence has been established. We discuss a similarity account of the transformational paradigm based on similarity chains, which predicts that when the transformation is more gradual the identity of the transformed object is less likely to change. Conversely, we suggest that an essentialist approach to categorisation predicts that essences are more likely to change in gradual transformations, across generations, as is the case with evolutionary change of species. In two experiments we examined the scope of the similarity versus the essentialist account in the transformational paradigm. With space aliens, the similarity account was superior to the essentialist one, but the converse was true with earth creatures. We suggest that an essentialist mode of categorisation is more likely than a similarity one for stimuli that are in better correspondence with our naïve understanding of the world. 相似文献

Ericsson and Kintsch (1995) proposed that, in situations of expertise, individuals can overcome working memory limitations by using long-term working memory. It allows a greater capacity than working memory thanks to long-term memory encoding and retrieving. To test this characteristic, an adaptation of Daneman and Carpenter's (1980) reading span was used. To operationalise expertise, the personalisation method (Guida & Tardieu, 2005) was employed. In Experiment 1, a personalised group, which read reading span sentences that mentioned familiar locations, was compared to a nonpersonalised group, which read sentences with unfamiliar locations. In Experiment 2, a personalised group, which read reading span sentences with neutral locations, was encouraged to mentally personalise these locations by thinking about known locations. This group was compared to a nonpersonalised group, which was encouraged to think about unknown locations. The personalised groups were expected to store and retrieve information in long-term memory via long-term working memory more easily than the nonpersonalised groups, which had to count massively on working memory. The results showed that personalisation enhanced reading span and confirmed one implication of the long-term working memory theory: high- and low-reading-span differences could also be due to long-term memory retrieval. Finally, these results are interpreted in terms of interaction between working memory size and long-term memory knowledge, showing that participants with a lower reading span benefited more from high domain knowledge than participants with a higher reading span. 相似文献

The estimation of model parameters in structural equation models with polytomous variables can be handled by several computationally efficient procedures. However, sensitivity or influence analysis of the model is not well studied. We demonstrate that the existing influence analysis methods for contingency tables or for normal theory structural equation models cannot be applied directly to structural equation models with polytomous variables; and we develop appropriate procedures based on the local influence approach of Cook (1986). The proposed procedures are computationally efficient, the necessary bits of the proposed diagnostic measures are readily available following an usual fit of the model. We consider the influence of an individual cell frequency with respect to three cases: when all parameters in an unstructured model are of interest, when the unstructured polychoric correlations are of interest, and when the structural parameters are of interest. We also consider the sensitivity of the parameters estimates. Two examples based on real data are presented for illustration.The work described in this paper was partially supported by a Chinese University of Hong Kong Postdoctoral Fellows Scheme and a grant from the Research Grants Council of the Hong Kong Special Administrative Region, China (RGC Ref. No. CUHK4186/98P). We are indebted to P.M. Bentler and M.D. Newcomb for providing the data set, Michael Leung for his assistance, and the Editor and the referees for some very valuable comments. 相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。 相似文献

Past research shows that authoritarian individuals hold strong opinions about a variety of political and social issues, such as race relations and military conflict. What has not been established, though, is the amount of general political knowledge that authoritarians possess. In this study, three groups of college students were administered Altemeyer's Right-Wing Authoritarianism (RWA) scale; most of them also received items assessing general political knowledge and specific knowledge about the 2000 presidential election, as well as items assessing interest in politics. Relative to students with low RWA scores, those with high scores possessed less political knowledge; moreover, they expressed less interest in learning about politics. In general, authoritarianism was unrelated to how individuals got their political information or how credible they found their sources. The implication that authoritarians hold strong attitudinal beliefs with weak political knowledge is discussed. 相似文献

Michael Lamport Commons 《Journal of Adult Development》2002,9(3):155-157
The current issue of The Journal of Adult Development addresses one of the threads of adult development, namely stage and stage change. There are four major forms of adult developmental study that can be identified: positive adult development, directionless change, stasis, and decline. The first of the four forms, positive adult developmental processes, is divided into at least six areas of study: hierarchical complexity (orders, stages), knowledge, experience, expertise, wisdom, and spirituality. The topic of this special issue, stage and stage change, is therefore part of the study of positive adult developmental processes. Finally, the manner in which these topics are studied both in this special issue and elsewhere can be characterized in terms of three broad classifications (Commons & Bresette, 2000, Commons & Miller, 1998) for the acquisition of knowledge and the verification of truth in general. These classifications include analytic, experiential, and empirical means to reach truth. 相似文献

中学生知识获得过程是从情景记忆向语义记忆转化的过程 总被引:2,自引:0,他引:2
本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态:记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。 相似文献

古希腊哲学最早将美德与知识相联系,“真”的达到就是“善”的实现,人的合目的性是建立在其合规律性的基础上的,伦理学从此有了独立存在的根据。近代知识论提出“知识就是力量”,将获得知识与获得幸福视为同一,知识(理性)是建立伦理的绝对普遍的坚实基础,人的尊严和主体性成为伦理追求的最大价值。20世纪以来,由于科学知识的异化,“知识与人的幸福和命运问题”凸现在当代伦理学面前。为知识找寻一条“应然”的光明之路,不仅是伦理学的理论使命,也是人类自身的神圣使命。 相似文献
