学习判断是元认知判断的一种重要形式,是个体对随后的记忆成绩的预测。当个体在多次学习-测验任务中学习词对时,学习判断出现了练习伴随低估效应。研究者对此进行了大量的实验并提出了多种理论,如线索应用模型,提取流畅性假说和基点-校正假说。但是,Koriat等人通过分析发现练习伴随低估效应可能不是单一因素作用的结果,而是多种效应共同影响作用的表现,并由此提出了记忆去偏差假说。文章指出了目前研究中还存在的问题以及未来研究的方向 相似文献

再认条件下元监测判断的影响因素 总被引:1,自引:0,他引:1
探讨了再认条件下元监测判断的影响因素。以中文双字词对作为实验材料 ,安排在不同预先呈现时间、有无进行有意识记 ,以及不同识记遍数等条件下进行元监测判断。用计算机随机呈现项目 ,再认之前先让被试做元监测判断 ,判断是否是记过的项目的把握程度 ,再对有意识记过的项目做迫选再认 ,作为标准测验 ,以验证元监测判断的准确性。结果是预先呈现时间长、有意识记过的和识记遍数多的项目 ,对其再认的反应时较短 ,相应的元监测判断等级也较高 ;对只看而未有意记过的项目的判断是呈现时间长的判断等级反而低于呈现时间短的。此结果表明 ,再认条件下 ,元监测判断的等级的高低与识记项目的激活程度有关 相似文献

类似性结构组合的实验研究 总被引:1,自引:1,他引:0
在国外研究使用点击映射(one—shot mapping)的基础上,本研究在一个实验中从新的角度使用了点击映射的方法探讨了关于类似性的一种观点:类似性判断与差异性判断不是一种对立的镜像关系;研究结果表明。类似性判断与差异性判断都是结构组合。 相似文献

本研究采用5(学习次数)×2(材料难度)被试内设计,考察材料难度和学习次数对即刻和延迟学习判断绝对准确性的影响。45名大学生被试参加实验,共收集有效数据37个。结果表明:(1) 即刻条件下,高、低难度词对都出现了练习伴随低估效应;(2) 延迟条件下,高、低难度词对均未出现练习伴随低估效应。对低难度词对的学习判断准确预测了回忆成绩,高难度词对则出现了练习伴随高估效应;(3) 随着学习次数的增加,不同难度词对在即刻条件下的练习伴随低估效应趋于消失,延迟条件下高难度词对的练习伴随高估效应趋于消失。 相似文献

Although prior studies have found that people generally underweight advice from others, such discounting of advice is not universal. Two studies examined the impact of task difficulty on the use of advice. In both studies, the strategy participants used to weigh advice varied with task difficulty even when it should not have. In particular, the results show that people tend to overweight advice on difficult tasks and underweight advice on easy tasks. This pattern held regardless of whether advice was automatically provided or whether people had to seek it out. The paper discusses implications for the circumstances under which people will be open to influence by advisors. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

In an era when lies and misrepresentations about historical events easily become firmly rooted, Michael Sells's discussion illustrates the importance of careful historical research as a moral enterprise. In addition to the skills of the historian, however, there is also room in this enterprise for those of the ethicist. In particular, I warn against confusing the truth or falsity of claims about one narrow historical period with larger questions about the moral meaning and significance of those claims. Illustrating this, I argue one cannot assess the legitimacy of competing nationhood claims solely on the basis of the deeds of specific actors. Nor should the actions of a single individual like the Grand Mufti of Jerusalem be converted into a totalizing claim about the rights of the Palestinian people. 相似文献

In optimal design research, designs are optimized with respect to some statistical criterion under a certain model for the data. The ideas from optimal design research have spread into various fields of research, and recently have been adopted in test theory and applied to item response theory (IRT) models. In this paper a generalized variance criterion is used for sequential sampling in the two-parameter IRT model. Some general principles are offered to enable a researcher to select the best sampling design for the efficient estimation of item parameters. 相似文献

It is commonly supposed that acting and judging ought to rest on a community-wide, binding definition of what is right and respectable, that is, a substantial consensus. Such consensus is thought possible only when we engage shared values and criteria, when we use knowledge and abilities appropriated through education. On this view, education deals with the reproduction of consensus and, hence, with the passing on of traditions and norms. On my view, we need to question the framework in which the debate over social erosion takes place. I take a cue from remarks of Hannah Arendt and question the presupposition that acting and judging in a right way requires both common values and the appropriation of what we call knowledge of criteria and principles. I do not suggest that knowledge has nothing to do with acting and judging. Rather, I wish to draw attention to (Arendt's concept of) thinking as a condition for acting and judging. Here, thinking has nothing to do with knowledge or with appropriation. Rather, it has to do with living-together with somebody. Educa-tion for thinking is, then, a public thinking which leads out of the serf and into communal responsibility. On this treatment, the educator is to be a faithful guardian of this calling out into responsibility. 相似文献

Abstract. The paper reviews criteria which have been used to distinguish science from nonscience and from pseudo–science, and it examines the extent to which they can usefully be applied to "creation science." These criteria do not force a clear decision, especially as creation science resembles important eighteenth–century forms of orthodox science. Nevertheless, the proponents of creation science may be accused of pious fraud in failing to concede in their political battles that their "science" is tentative and tendentious and will continue to be so while it remains archaic and poorly integrated into the rest of science. 相似文献
