Participants rated Intuition, Suddenness, Pleasure, and Certainty accompanying their solutions to items of a popular fluid intelligence test -- Raven's Advanced Progressive Matrices (RAPM) -- that varied from easy (around 80% correct) to difficult (around 20% correct). The same ratings were collected from four insight problems interleaved with…

An area of particular importance when examining index scores on the Wechsler Intelligence Scale for Children--Fifth Edition (WISC-V) is the utilization and interpretation of critical values and base rates associated with differences between an individual's subtest scaled score and the individual's mean scaled score for an index. For the WISC-V,…

Purpose: The goal of this study was to examine potential mediators of the relationship between developmental language disorder (DLD) status and executive function performance. Method: Participants included preschoolers, of whom 80 met the diagnostic criteria for DLD and 103 were categorized as having typical language abilities. Participants'…

The Flynn effect, which advocated that there was a rise in the global IQ score, was widely accepted by the relevant scientific community. However, there are recent research findings that this effect has been reversed. In this study, both Flynn and anti-Flynn effects were investigated. The purpose of this study is to analyze students' general,…

The testlet design is very popular in educational and psychological assessments. This article proposes a new cognitive diagnosis model, the multiple-choice cognitive diagnostic testlet (MC-CDT) model for tests using testlets consisting of MC items. The MC-CDT model uses the original examinees' responses to MC items instead of dichotomously scored…

This paper estimates the acute effect of community-level homicides on early childhood language development and explores the moderating role of maternal efficacy and satisfaction in Chile. It uses data from the 2017 wave of the Early Childhood Longitudinal Survey of Chilean Children (N = 1194, M[subscript age]: 52.8 months, 52% girls). Children in…

Our study investigated the differences in speech performance and neurophysiological response in groups of school-age children with unilateral hearing loss (UHL) who were otherwise typically developing (TD). We recruited a total of 16 primary school-age children for our study (UHL = 9/TD = 7), who were screened by doctors at Shin Kong Wu-Ho-Su…

The field of giftedness legitimates itself on the basis of correlations of gifted-identification measures with future success that do not mean what they often are taken to mean. When one views the inadequacies of these correlations, the field turns out to be much like the emperor who had no clothes. This essay reviews some of the assumptions upon…

A prior randomized trial found a school social intervention yielded significantly better outcomes (social and autism features) immediately following intervention compared to typical school programming (services-as-usual [SAU]) for children on the autism spectrum. In that study, children in the SAU condition subsequently completed a summer social…

The advancement of technology in education has transformed traditional classrooms into virtual learning environments yet concerns persist about how these technologies may inadvertently perpetuate racial stereotypes. Our study employed a 2 × 2 factorial design, with the first factor being the race of participants (Black, White) and the second…

This article presents the outcomes of a pedagogical experiment conducted to assess the efficacy of incorporating experimental logical tasks and exercises within the curriculum of the discipline "Medical Informatics" as a means to foster the development of logical thinking among future medical professionals. The study emerged from the…

The Wechsler Intelligence Scales for Children (WISC) are the most widely used instrument in assessing cognitive ability, especially with children with autism spectrum disorder (ASD). Previous literature on the WISC has demonstrated a divergent pattern of performance on the WISC for children ASD compared to their typically developing peers;…

This investigation provides internal consistency reliabilities for the Wechsler Memory Scale--Fourth Edition (WMS-IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from 0.00 to 0.93 for Adults and 0.25 to 0.94 for Older Adults. Three of 91 Adult…

Challenging behaviour is a problematic issue for students with intellectual disability, including those in special education settings. While there is a need to address challenging behaviour in these schools, most Vietnamese classroom teachers struggle to deal with those behaviours due to their lack of effective strategies. In response, this first…

Background: Life expectancy is on rise and the intriguing question is: When does cognitive decline occur among adults with intellectual disability, compared to adults with typical development? This cross-sectional study examined cognitive performance of crystallised/fluid intelligence, working and long-term memory of adults with intellectual…
