Self‐explaining is an effective metacognitive strategy that can help learners develop deeper understanding of the material they study. This experiment explored if the format of material (i.e., text or diagrams) influences the self‐explanation effect. Twenty subjects were presented with information about the human circulatory system and prompted to self‐explain; 10 received this information in text and 10 in diagrams. Results showed that students given diagrams performed significantly better on post‐tests than students given text. Diagrams students also generated significantly more self‐explanations that text students. Furthermore, the benefits of self‐explaining were much greater in the diagrams condition. To discover why diagrams can promote the self‐explanation effect, results are interpreted with reference to the multiple differences in the semantic, cognitive and affective properties of the texts and diagrams studied. 相似文献

Fallacies are things people commit, and when they commit them they do something wrong. What kind of activities are people engaged in when they commit fallacies, and in what way are they doing something wrong? Many different things are called fallacies. The diversity of the use of the concept of a fallacy suggests that we are dealing with a family of cases not related by a common essence. However, we suggest a simple account of the nature of fallacies which encompasses them all, viz., the term “fallacy” is our most general term for criticizing any general procedure used for the fixation of beliefs that has an unacceptably high tendency to generate false or unfounded beliefs, relative to that method of fixing beliefs. Very different sorts of things called fallacies are examined in the light of this account, e.g., denying the antecedent, circular arguments, so-called informal fallacies, and propositions said to be fallacies. We do not provide a theory of fallacies. Still, on our account pretty much all of those things that have been called fallacies are fallacies, and they have been called fallacies for pretty much the same reasons. 相似文献

This paper is concerned with the processing of informal arguments, that is, arguments involving probable truth. A model of informal argument processing is presented that is based upon Hample's (1977) expansion of Toulmin's (1958) model of argument structure. The model postulates that a claim activates an attitude, the two components forming a complex that in turn activates reasons. Furthermore, the model holds occurrence of the reason, or possibly the claim and the reason, activates values. Three experiments are described that provide support for the model.This research was supported by the Mellon Foundation and by the Office of Educational Research and Improvement of the Department of Education via an award for the Center for the Study of Learning to the Learning Research and Development Center.

Culture wars: American moral divisions across the adult lifespan 总被引:1,自引:0,他引:1
Lene Arnett Jensen 《Journal of Adult Development》1997,4(2):107-121
Sociologists have argued that the public moral debate in contemporary America is characterized by a “culture war,” pitting
“orthodox” and “progressivist” groups against one another (Hunter, 1991). This study addressed whether the culture war is
evident in the moral thinking of ordinary Americans, and whether age-related patterns exist. Sixty fundamentalist Baptists
(orthodox) and 60 mainline Baptists (progressivist) evaluated and reasoned about moral issues such as divorce and abortion.
Each group was divided evenly into three age groups copsisting of young, midlife, and older adults. Moral reasoning was analyzed
in terms of Shweder's (1990) ethics of autonomy, community, and divinity. Within all three age groups, progressivists used
the ethic of, autonomy more than orthodox participants. Orthodox participants used the ethic of divinity more than progressivists.
Orthodox and progressivist groups did not differ much in their use of the ethic, of community. Very few age group differences
were found within the orthodox and progressivist groups. It is concluded that morality is conceived of in markedly different
wasy by orthodox and progressivist groups, and that these conceptions are consistent across age groups. 相似文献

An incidental extension of the central domain of argumentation theory with non-classical ways of constructing arguments seems to automatically raise a question that is otherwise rarely posed, namely whether or not it is useful to consider the sex of the arguer. This question is usually posed with regard to argumentation by women in particular. Do women rely more, or differently than men do on non-canonical modes of reasoning stemming from the realm of the emotional, physical and intuitive, instead of the logical? One may simply refer this question to folk-linguistics. One may also take the question seriously, given the findings on women's linguistic behaviour, and for various other reasons that will be explained below.Section 1 sums up the most frequently quoted differences in language use between women and men. This is followed by a non-exhaustive, interdisciplinary review of studies on male/female differences in verbal and written argumentation.Section 2 discusses the role of language and texts in generating and maintaining ideas on gender. These gender messages not only influence the actual argumentation behaviour of women and men, but also the way such behaviour is valued.Section 3 subsequently shows that our ideas on rationality are gendered, and therefore also our ideas on the proper central domain of argumentation theory.Section 4 briefly reflects on why this kind of wrong question about the reasoning of women should sometimes be addressed seriously anyway. 相似文献

设计三种情境考察被试的推理情况,并试图揭示儿童是怎样进行传递性关系推理的。结果显示:(1)3—6岁儿童具有进行传递性关系推理能力;(2)造成我国3—6岁儿童作传递性关系推理失败的原因有二:一是错误理解比较句式,二是没有记住前提;(3)3—6岁儿童进行传递性关系推理的内部过程不同:小年龄段被试多采用“局部加工模式”,大龄段被试多采用“整体空间加工模式”。 相似文献

图形型归纳推理的神经机制:一项fMRI研究 总被引:1,自引:0,他引:1
利用fMRI脑成像技术探讨图形型归纳推理的神经机制。设计了一种由图形形状和条纹方向描述的简单几何图形组成的归纳推理任务,这种图形型任务与以往研究中常用的语句型归纳推理任务是同质的。根据两个图形共享特征数量的不同设计了两种实验任务:共享两个特征(2T)和共享一个特征(1T),以休息基线(Rest)作为控制任务。2T和1T任务均为归纳推理任务,但2T任务包含知觉特征整合成分,而1T任务不包括。结果发现:与控制任务相比,归纳推理任务在前额区(BA6、9、11、46、47)、尾状核、壳核和丘脑等脑区有显著激活,反映了"前额皮层-纹状体-丘脑"通路在图形型归纳推理中的重要作用;图形型归纳推理中的知觉信息整合与右侧额下回(BA47)、双侧尾状核头部、壳核等脑区有关。 相似文献

四卡问题的内容促进效应的实验研究 总被引:17,自引:4,他引:17
本研究设计了2种抽象材料和4种具体材料的四卡问题,对436名大学生进行测试,以考察被试解决四卡问题时所采用的思维方式并检验命题内容对推理的影响。结果表明,四卡问题十分困难,具体内容的四卡问题并不能产生促进效应,大学生的推理表现出“匹配偏向”的特点。 相似文献

记录14名正常成人完成四种空间推理及一种基线任务(记忆任务)时的事件相关电位,对空间推理的脑电活动情况进行考察。研究结果表明,在200ms-900ms窗口,推理任务比基线任务诱发更大的正成分。对不同推理任务的比较表明,具体与抽象材料的单模型推理诱发相似的波形;单模型与有效的双模型任务诱发的ERP成分明显不同,在300ms-600ms窗口,后者比前者诱发更大的正波;在200-600ms时间窗口,存在有效结论与无有效结论的双模型问题也诱发明显不同的ERP波形。研究的结果表明,推理与记忆涉及不同的加工要求,推理需要整合前提的信息,而记忆只需要储存前提信息。在解决双模型推理问题时,从200ms开始,被试就对刺激材料进行初步的加工与判断,随后对双模型问题采用有注解的单模型加工策略。另外,不同材料的空间推理任务之间的波形较为一致,表明视觉表象并未明显影响空间推理过程。 相似文献
