With the purpose of increasing the knowledge of the psychometric properties of the 70-item Danish Word Association Test, data from three samples of non-patients and psychiatric patients (N = 326) were used to provide two measures of affectivity of the stimulus words, response heterogeneity and reaction time prolongation. It was possible to fit an item response theory one-parameter measurement (Rasch) model to the number of reaction time prolongations (> or =3 seconds) for 54 of the stimulus words. Correlation between Rasch-model item parameters and response heterogeneity was high (r = 0.86), while no correlation was found between either of these measures and frequency of the stimulus words in the Danish language. Both measures of stimulus affectivity supported a theoretically based classification of stimulus words as emotional or neutral. Response heterogeneity measures and Rasch measurement item and person parameters for reaction time prolongations are provided. 相似文献

A Bayesian procedure to estimate the three-parameter normal ogive model and a generalization of the procedure to a model with
multidimensional ability parameters are presented. The procedure is a generalization of a procedure by Albert (1992) for estimating
the two-parameter normal ogive model. The procedure supports analyzing data from multiple populations and incomplete designs.
It is shown that restrictions can be imposed on the factor matrix for testing specific hypotheses about the ability structure.
The technique is illustrated using simulated and real data.

The identifiability of item response models with nonparametrically specified item characteristic curves is considered. Strict
identifiability is achieved, with a fixed latent trait distribution, when only a single set of item characteristic curves
can possibly generate the manifest distribution of the item responses. When item characteristic curves belong to a very general
class, this property cannot be achieved. However, for assessments with many items, it is shown that all models for the manifest
distribution have item characteristic curves that are very near one another and pointwise differences between them converge
to zero at all values of the latent trait as the number of items increases. An upper bound for the rate at which this convergence
takes place is given. The main result provides theoretical support to the practice of nonparametric item response modeling,
by showing that models for long assessments have the property of asymptotic identifiability.

The linear logistic test model (LLTM) specifies the item parameters as a weighted sum of basic parameters. The LLTM is a special case of a more general nonlinear logistic test model (NLTM) where the weights are partially unknown. This paper is about the identifiability of the NLTM. Sufficient and necessary conditions for global identifiability are presented for a NLTM where the weights are linear functions, while conditions for local identifiability are shown to require a model with less restrictions. It is also discussed how these conditions are checked using an algorithm due to Bekker, Merckens, and Wansbeek (1994). Several illustrations are given.This article was written while the first author was a post doctoral fellow at the university of Twente.

嗓音源判断过程中的范畴效应和通道效应 总被引:1,自引:1,他引:0
该项研究通过设计4种实验条件,旨在探讨不同嗓音词的再认和嗓音判断过程各自的特点及其相互联系。4种实验条件是由2种诵读方式和2种测试方式组合而成,2种诵读方式为同范畴同嗓音和同范畴异嗓音,2种测试方式为视觉呈现和听觉呈现。52名大学生被试随机分成4个独立的组,分别接受一种实验处理。实验结果显示:(1)同范畴同嗓音条件与同范畴异嗓音条件相比,前者项目词的嗓音源判断效果好。提示增加相同记忆源项目间语义联系将有利于记忆源的检测判断。(2)项目再认与项目嗓音判断结果不完全一致,只有在诵读方式为同范畴同嗓音测试方式为听觉呈现情境下,两者有较高的正相关。(3)在同范畴同嗓音诵读条件下,再认反映出学习和测试通道源一致性优势效应,嗓音判断没有反映出通道源一致性优势效应。 相似文献

Composite links and exploded likelihoods are powerful yet simple tools for specifying a wide range of latent variable models.
Applications considered include survival or duration models, models for rankings, small area estimation with census information,
models for ordinal responses, item response models with guessing, randomized response models, unfolding models, latent class
models with random effects, multilevel latent class models, models with log-normal latent variables, and zero-inflated Poisson
models with random effects. Some of the ideas are illustrated by estimating an unfolding model for attitudes to female work
participation.

Using Lumsden’s Thurstonian fluctuation model as a starting point, this paper attempts to develop a unidimensional item response
theory model intended for binary personality items. Under some additional assumptions, a new model is obtained in which the
item characteristic curves are defined by a cumulative Pearson-Type-VII distribution, and the person response curves are two-parameter
normal ogives. Procedures for fitting the new model are proposed. Furthermore, the relations between individual fluctuation
and scalability are discussed, and a scalability index based on the new model is proposed. All the developments in this paper
are illustrated using two empirical examples. 相似文献

个人—组织匹配的研究现状与展望 总被引:10,自引:0,他引:10
个人—组织匹配主要探讨个人和组织之间的相容性以及实现这种相容性的前提和结果。个人与组织可能以附助或补偿的方式形成匹配。尽管在操作指标的选择上,研究者们没有达成共识,但他们的研究结论都同样体现了个人—组织匹配在员工的组织进入、工作态度、离职意向、工作压力、亲社会行为、工作绩效和组织文化培训等方面的管理价值。展望该领域的进一步研究,自我报告的研究方法以及高水平匹配的益处是令人质疑的,匹配的评估指标也亟待明确。 相似文献

HSK主观考试评分的Rasch实验分析 总被引:1,自引:0,他引:1
主观评分中存在的不一致性导致主观评分的信度降低。多面Rasch模型基于项目反应理论,可以应用于评分员效应的识别和消除,从而提高主观评分的信度。该文介绍多面Rasch模型的理论和应用框架,设计了基于该模型的HSK主观考试评分质量控制应用框架,利用HSK作文评分数据进行了实验验证。 相似文献
