本研究采用DRM范式,探讨了生命性对真实和虚假记忆的影响。实验1使用类别呈现词语强化类别加工,实验2伪随机呈现词语弱化类别加工并进行即时及延时探测。结果发现:(1)当强化类别加工时,生命性和类别对击中率有相类似的促进效应;(2)当弱化类别加工并进行即时探测时,生命性对击中率的促进作用最强;(3)类别效应促进真实记忆和虚假记忆,但生命性效应仅促进了真实记忆,而不影响虚假记忆的产生;(4)在即时与延时探测中均发现类别效应和生命性效应。本研究证明了:(1)生命性效应的作用机制不同于类别效应;(2)生命性效应对真实和虚假记忆的作用机制不同;(3)类别效应和生命性效应的存在时效长达24小时,但是生命性效应的衰退速度较快。 相似文献

For ordinal measurement the concept of an individual propensity distribution is developed. For any given individual the mean of this distribution is his true score, for which estimation procedures are discussed. Two measures of individual dispersion are considered and their distributions derived in the null case. These measures are shown to be counterparts at the individual level of Kendall's tau and Spearman's rho. Estimation of the two dispersion measures from sample data is investigated, and the relation of these estimates to the variance of the individual propensity distribution is derived. 相似文献

To date, virtually all techniques appropriate for ordinal data are based on the uniform probability distribution over the permutations. In this paper we introduce and examine an alternative probability model for the distribution of ordinal data. Preliminary to deriving the expectations of Spearman's rho and Kendall's tau under this model, we show how to compute certain conditional expectations of rho and tau under the uniform distribution. The alternative probability model is then applied to ordinal test theory, and the calculation of true scores and test reliability are discussed. 相似文献

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance. 相似文献

错误记忆指的是人们会回忆或再认那些没有出现过的事件。目前,针对错误记忆的研究多集中于视力正常的人群。国外近年来有针对视障人群错误记忆的研究认为,在听觉学习情境中视障成人有更好的真实记忆和更低的错误记忆。目前对于盲生的错误记忆特征尚缺乏研究。而盲文摸读作为视障人群重要的学习方式,其对视障人群的真实记忆和错误记忆的影响尚未有研究者关注。本研究以初中盲生和视力正常学生作为研究对象,采用DRM范式,发现被试采用阅读学习(盲生摸读盲文,视力正常学生阅读屏幕文字)和听觉学习两种学习方式下,都发现被试身上存在稳定的错误记忆;盲生的错误记忆显著低于视力正常学生。在摸读学习方式下,盲生真实记忆好于听觉学习方式。 相似文献

As pointed out by Sijtsma (in press), coefficient alpha is inappropriate as a single summary of the internal consistency of a composite score. Better estimators
of internal consistency are available. In addition to those mentioned by Sijtsma, an old dimension-free coefficient and structural
equation model based coefficients are proposed to improve the routine reporting of psychometric internal consistency. The
various ways to measure internal consistency are also shown to be appropriate to binary and polytomous items.

用信息函数法对标准参照测验作质量分析 总被引:1,自引:0,他引:1
根据项目反应理论的信息函数法,以自主开发的“现代教育和心理测量通用分析系统”为工具,对两个大规模实施的标准参照测验进行了测验质量分析。结果说明,信息函数分析法比经典真分数理论分析法,可以获得更丰富、深刻、有针对性的资料,能对项目筛选修订、测验编制开发给出有力的指导,值得大力引进、推广。 相似文献
