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…

The present study examined the factor structure of the Differential Ability Scales--Second Edition (DAS-II) core subtests from the standardization sample via confirmatory factor analysis (CFA) using methods (bifactor modeling and variance partitioning) and procedures (robust model estimation due to nonnormal subtest score distributions)…

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate…

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…

Tests of measurement invariance are essential to determining whether individual scores or group averages are comparable across populations. While international comparisons of mean IQ scores are common, tests of measurement invariance for intelligence test batteries (necessary for comparisons to be empirically supported) are rare. In this study,…

Children's speech is influenced by the speech they hear, in particular by the parental speech addressed directly to them. The aim of this study was to analyse toddlers' speech with their parents and to investigate the influence of specific characteristics of child-directed speech on child speech in real time during mother-child and father-child…

This study examines the narrative production of 12 trilingual children aged 8;7-11;10 in three languages: heritage Romanian as a first language, mainstream English as a second, and school French as a third. Narrative macrostructure was analyzed via the Narrative Structure Scheme, while microstructure was assessed via story length, lexical…

The current study examined whether social competence and autistic traits are related to anxiety and depression in autistic and non-autistic children. Parents of 340 children aged 6 to 12 years old, including 186 autistic and 154 non-autistic children completed the Autism Spectrum Quotient (AQ) to assess their child's autistic traits, the…

Objective: This study investigated the effect of Cognitive Rehabilitation Training (CRT) on executive functions, problem solving, and attention in students with a specific learning disorder (SLD). Method: Forty-two SLD students from the third to sixth grade (8-12 years old) were randomly assigned to 16 sessions of CRT (n = 21) or to a control (n =…

Brian Simon (1915-2002), a Marxist historian and educationist in Britain, was a leading pioneer in the comprehensive education movement. Although Simon's great contribution to this movement has been recognised by historians, the development of Simon's ideas and his actions in this movement have hardly been examined in great depth by previous…

This study investigated the utility of four WAIS-IV Digit Span (DS) indices (traditional Reliable Digit Span [RDS], RDS-Working Memory [RDS-WM], RDS-Revised [RDS-R], and DS Age-Corrected Scaled Score [ACSS]) as embedded performance validity tests (PVTs) among a sample of 342 consecutive adults referred for neuropsychological evaluation of ADHD.…

This study investigated the systematic rise in cognitive ability scores over generations, known as the "Flynn Effect," across middle childhood and early adolescence (7-15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously…

Learning agility is a relatively novel concept and has the potential to be considered an important characteristic of an effective teacher. Thus, a scale to measure it might be beneficial especially for selecting and recruiting teachers. Based on this notion, the purpose of this study was to develop a scale to measure the learning agility of…

Background/Context: In Brazil, the 1920s and 1930s were characterized by initiatives intended to reform public school systems at the state level. As in the case of both educators whose work we analyze in this article, Brazilian educators traveled abroad searching for experiences that could help them think about the modernization of education in…
