The present study compares the fit of two- and three-parameter logistic (2PL and 3PL) models of item response theory in the performance of preschool children on the Raven's Colored Progressive Matrices. The test of Raven is widely used for evaluating nonverbal intelligence of factor g. Studies comparing models with real data are scarce on the…

Children across the United States are increasingly learning academic content through two-way dual-language education (http://www.cal.org/twi/). This education model provides instruction through two languages in classrooms comprised of approximately equal numbers of native and non-native English speakers. For both language groups, this educational…

Abstract Attention-deficit/hyperactivity disorder (ADHD) and autism are neurodevelopmental disorders that emerge in childhood. There is increasing recognition that ADHD and autism frequently co-occur. Yet, questions remain among clinicians regarding the best ways to evaluate and treat co-occurring autism and ADHD. This review outlines issues…

Purpose: This research aimed to identify reliable tasks discriminating French-speaking adolescents with developmental language disorder (DLD) from their peers with typical language (TL) and to assess which linguistic domains represent areas of particular weakness in DLD. Unlike English, morphosyntax has not been identified as a special area of…

Intellectual impairments in preschoolers have been widely studied. A regularity that emerges is that children's intellectual impairments have an important impact on later adjustments in life. However, few studies have looked at the intellectual profiles of young psychiatric outpatients. This study aimed to describe the intelligence profile of…

This study aims to investigate the connection between the degree of visual impairment and educational task performance and management in the e-learning environment with an emphasis on writing and visual recognition disorders. The study was conducted in 2019 in Beijing city, Anhui province, Jiangsu province, Guizhou province, Zhejiang province…

A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

Procedures for identifying the gifted often make use of tests of general intelligence, among other assessments. Robert J. Sternberg recently suggested that identification of the gifted should further involve assessment of what he refers to as adaptive intelligence--the ability to adapt to real-world environments. Such a conception of intelligence…

Advanced Item Response Theory (IRT) practices serve well in understanding the nature of latent variables which have been subject to research in various disciplines. In the current study, 7-12 aged 2536 children's responses to 20- item Visual Sequential Processing Memory (VSPM) sub-test of Anadolu-Sak Intelligence Scale (ASIS) were analyzed with…

Distractors might display discriminatory power with respect to the construct of interest (e.g., intelligence), which was shown in recent applications of nested logit models to the short-form of Raven's progressive matrices and other reasoning tests. In this vein, a simulation study was carried out to examine two effect size measures (i.e., a…

The purpose of this study was to use multidimensional scaling (MDS) to investigate relations among scores from the standardization sample of the Wechsler Intelligence Scale for Children--Fifth edition (WISC-V; Wechsler, 2014). Nonmetric two-dimensional MDS maps were selected for interpretation. The most cognitively complex subtests and indexes…

Recent research has documented the academic disadvantage of low social class students, whose performance is impaired by competitive educational practices. Across 2 experiments, we examined whether the pursuit of performance-approach goals (aiming to outperform others) favors the emergence of this achievement gap. We first manipulated low versus…

The present research extends recent work on the prediction of preschool language skills by exploring prediction from decontextualized vocabulary comprehension. Vocabulary comprehension was a stronger predictor than parent-reported production, yielding a quadrupling of variance accounted for relative to prior studies. Parallel studies (Studies 1…

This study compared students with specific learning disorders (SLDs) and attention-deficit/hyperactivity disorder (ADHD) based on the Formal Elements Art Therapy Scale (FEATS). Thirty students with SLDs, 30 students with ADHD, and 30 students without SLDs/ADHD in Babol (Iran) completed the Person Picking an Apple from a Tree (PPAT) assessment.…

Background and Aims: Parent-child interaction therapy (PCIT) is an evidence-based behavioral parent training program designed for preschool-age children that emphasizes supporting parent-child interaction patterns to improve child behavior and enhance the quality of parent-child relationships. PCIT has been deemed efficacious in treating children…
