Auditory overshadowing occurs when the presence of an auditory stimulus interferes with visual processing. The current study tested whether this occurs due to a privileged attentional status of auditory input or due to the dynamic characteristics of auditory input. To address these questions, preschoolers completed one of four discrimination tasks. In the sound, motion, and item baseline condit...

In this note we describe several of the IRT modeling features implemented in Mplus, namely the the item characteristic curves, the item information curves, the total information curve, item difficulty parameter and item discrimination parameter. Different estimators and parameterizations are considered. We also provide details on the Mplus implementation of the Partial Credit Model (PCM), the 3...

INTRODUCTION Little is known about the relationship between discrimination and distress among multiple racial groups because previous studies have focused primarily on either blacks or Asian Americans. The objective of this study was to assess the association between self-reported experiences of racial discrimination and symptoms of psychological distress among 5 racial/ethnic groups in Califor...

This study was an attemptto provide detailed information of the strengths and weaknesses of test takers‟ real ability through cognitive diagnostic assessment, and to detect differential item functioning in each test item. The rationale for using CDA was that it estimates an item‟s discrimination power, whereas clas- sical test theory or item response theory depicts between rather within item mu...

PURPOSE The reliability of test is determined by each items' characteristics. Item analysis is achieved by classical test theory and item response theory. The purpose of the study was to compare the discrimination indices with item response theory using the Rasch model. METHODS Thirty-one 4th-year medical school students participated in the clinical course written examination, which included ...

a bstract background: one of the reported obstacles to the achievement of universal access to human immunodeficiency virus (hiv) prevention, treatment, care, and support programs includes stigma and discrimination from health workers, particularly nurses. since nursing students would become future practising nurses and are most likely exposed to caring for people living with hiv/aids (pl wha) d...

Most researchers investigate the corrected item-total correlation of items when analyzing item discrimination in multi-dimensional structures under Classical Test Theory, which might lead to underestimating discrimination, thereby removing from test. Researchers with factors that belongs; however, getting a general overview entire test is impossible. Based on this problem, study aims recommend ...

OBJECTIVE To evaluate the level of HIV/AIDS knowledge among men who have sex with men in Brazil using the latent trait model estimated by Item Response Theory. METHODS Multicenter, cross-sectional study, carried out in ten Brazilian cities between 2008 and 2009. Adult men who have sex with men were recruited (n = 3,746) through Respondent Driven Sampling. HIV/AIDS knowledge was ascertained th...

The aim of this study was to develop a scale instrument for measuring academic intellectual capital in the Turkish higher education context depending on student perceptions. sample consisted students institutions 2020-2021 year. Data were gathered two stages. Exploratory Factor Analysis (EFA) conducted first stage and Confirmatory (CFA) second stage. EFA 538 studying 96 while CFA 492 112 instit...

OBJECTIVE Although both Black and White individuals report racial discrimination, self-report measures of exposure to racial discrimination that can be used across races/ethnicities are rare. The primary aim of our study was to determine if the Schedule of Racist Events (SRE), which was designed for use in Black samples, should also be used in White samples, and if so, what modifications to the...
