Likert-type self-report scales are frequently used in large-scale educational assessment of social-emotional skills. Self-report scales rely on the assumption that their items elicit information only about the trait they are supposed to measure. However, different response biases may threaten this assumption. Specifically, in children, the response style of acquiescence is an important source of systematic error. Balanced scales, including an equal number of positively and negatively keyed items, have been proposed as a solution to control for acquiescence, but the reasons why this design feature worked from the perspective of modern psychometric models have been underexplored. Three methods for controlling for acquiescence are compared: classical method by partialling out the mean; an item response theory method to measure differential person functioning (DPF); and multidimensional item response theory (MIRT) with random intercept. Comparative analyses are conducted on simulated ratings and on self-ratings provided by 40,649 students (aged 11–18) on a fully balanced 30-item scale assessing conscientious self-management. Acquiescence bias was explained as DPF and it was demonstrated that: the acquiescence index is highly related to DPF; balanced scales produce scores controlled for DPF; and MIRT factor scores are highly related to scores controlled for DPF and the random intercept is highly related to DPF. 相似文献

Nesting of fast rhythmical brain activity (gamma) into slower brain waves (theta) has frequently been suggested as a core mechanism of multi‐item working memory (WM) retention. It provides a better understanding of WM capacity limitations, and, as we discuss in this review article, it can lead to applications for modulating memory capacity. However, could cross‐frequency coupling of brain oscillations also constructively contribute to a better understanding of the neuronal signatures of working memory compatible with theoretical approaches that assume flexible capacity limits? Could a theta‐gamma code also be considered as a neural mechanism of flexible sharing of cognitive resources between memory representations in multi‐item WM? Here, we propose potential variants of theta‐gamma coupling that could explain WM retention beyond a fixed memory capacity limit of a few visual items. Moreover, we suggest how to empirically test these predictions in the future. 相似文献

Decision‐making researchers purport that a novel cognitive ability construct, cognitive reflection, explains variance in intuitive thinking processes that traditional mental ability constructs do not. However, researchers have questioned the validity of the primary measure because of poor construct conceptualization and lack of validity studies. Prior studies have not adequately aligned the analytical techniques with the theoretical basis of the construct, dual‐processing theory of reasoning. The present study assessed the validity of inferences drawn from the cognitive reflection test (CRT) scores. We analyzed response processes with an item response tree model, a method that aligns with the dual‐processing theory in order to interpret CRT scores. Findings indicate that the intuitive and reflective factors that the test purportedly measures were indistinguishable. Exploratory, post hoc analyses demonstrate that CRT scores are most likely capturing mental abilities. We suggest that future researchers recognize and distinguish between individual differences in cognitive abilities and cognitive processes. 相似文献

汉语主动句、被动句的命题表征项目顺序特点 总被引:2,自引:1,他引:1
以中国大学生为被试,采用句子—图画验证任务(sentence-picture verification task )探讨了中国学生理解汉语主动句、被动句所形成的命题表征中项目顺序特点。结果表明,无论是语义水平较高的不可逆句,还是语义水平较低的可逆句,中国学生理解汉语主动句、被动句所建构的命题表征中项目顺序均为“施事→受事”。本研究结果初步表明,中国学生理解汉语主动句和被动句时,能根据它们不同的表层结构(汉语主动句的语言表达顺序为“施事→受事”、汉语被动句的语言表达顺序为“受事→施事”)建构相同的深层结构(语义内容的命题表征项目顺序“施事→受事”),可能是一个按照“施事→受事”固定方向进行的系列认知心理加工的过程 相似文献

A unifying framework for generalized multilevel structural equation modeling is introduced. The models in the framework, called generalized linear latent and mixed models (GLLAMM), combine features of generalized linear mixed models (GLMM) and structural equation models (SEM) and consist of a response model and a structural model for the latent variables. The response model generalizes GLMMs to incorporate factor structures in addition to random intercepts and coefficients. As in GLMMs, the data can have an arbitrary number of levels and can be highly unbalanced with different numbers of lower-level units in the higher-level units and missing data. A wide range of response processes can be modeled including ordered and unordered categorical responses, counts, and responses of mixed types. The structural model is similar to the structural part of a SEM except that it may include latent and observed variables varying at different levels. For example, unit-level latent variables (factors or random coefficients) can be regressed on cluster-level latent variables. Special cases of this framework are explored and data from the British Social Attitudes Survey are used for illustration. Maximum likelihood estimation and empirical Bayes latent score prediction within the GLLAMM framework can be performed using adaptive quadrature in gllamm, a freely available program running in Stata.gllamm can be downloaded from http://www.gllamm.org. The paper was written while Sophia Rabe-Hesketh was employed at and Anders Skrondal was visiting the Department of Biostatistics and Computing, Institute of Psychiatry, King's College London. 相似文献

Item response theory (IRT) and categorical data factor analysis (CDFA) are complementary methods for the analysis of the psychometric properties of psychiatric measures that purport to measure latent constructs. These methods have been applied to relatively few child and adolescent measures. We provide the first combined IRT and CDFA analysis of a clinical measure (the Short Mood and Feelings Questionnaire—SMFQ) in a community sample of 7-through 11-year-old children. Both latent variable models supported the internal construct validity of a single underlying continuum of severity of depressive symptoms. SMFQ items discriminated well at the more severe end of the depressive latent trait. Item performance was not affected by age, although age correlated significantly with latent SMFQ scores suggesting that symptom severity increased within the age period of 7–11. These results extend existing psychometric studies of the SMFQ and confirm its scaling properties as a potential dimensional measure of symptom severity of childhood depression in community samples. 相似文献

While negative local item dependence (LID) has been discussed in numerous articles, its occurrence and effects often go unrecognized. This is due in part to confusion over what unidimensional latent trait is being utilized in evaluating the LID of multidimensional testing data. This article addresses this confusion by using an appropriately chosen latent variable to condition on. It then provides a proof that negative LID must occur when unidimensional ability estimates (such as number right score) are obtained from data which follow a very general class of multidimensional item response theory models. The importance of specifying what unidimensional latent trait is used, and its effect on the sign of the LIDs are shown to have implications in regard to a variety of foundational theoretical arguments, to the simulation of LID data sets, and to the use of testlet scoring for removing LID.This paper is based in part on a chapter in the first author's doctoral dissertation, written at the University of Illinois at Urbana-Champaign under the supervision of William Stout. Part of this research has been presented at the annual meeting of the National Council on Measurement in Education, San Diego, California, April 14–16, 1998.The research of the first author was partially supported by a Harold Gulliksen Psychometric fellowship through Educational Testing Service and by a Research and Productive Scholarship award from the University of South Carolina. 相似文献

An IRT model with a parameter-driven process for change is proposed. Quantitative differences between persons are taken into
account by a continuous latent variable, as in common IRT models. In addition, qualitative interindividual differences and
autodependencies are accounted for by assuming within-subject variability with respect to the parameters of the IRT model.
In particular, the parameters of the IRT model are governed by an unobserved or “hidden'” homogeneous Markov process. The
model includes the mixture linear logistic test model (Mislevy & Verhelst, 1990), the mixture Rasch model (Rost, 1990), and
the Saltus model (Wilson, 1989) as specific instances. The model is applied to a longitudinal experiment on discontinuity
in conservation acquisition (van der Maas, 1993).
