In comparison to young adults, middle-aged and old people show lower scores in intelligence tests and slower response times in elementary cognitive tasks. Whether these well-documented findings can both be attributed to a general cognitive slow-down across the life-span has become subject to debate in the last years. The drift diffusion model can…

Raven's Standard Progressive Matrices (Raven 1941) is a widely used 60-item long measure of general mental ability. It was recently suggested that, for situations where taking this test is too time consuming, a shorter version, comprised of only the last series of the Standard Progressive Matrices (Myszkowski and Storme 2018) could be used, while…

We analyze a 12-item version of Raven's Standard Progressive Matrices test, traditionally scored with the sum score. We discuss some important differences between assessment in practice and psychometric modelling. We demonstrate some advanced diagnostic tools in the freely available R package, dexter. We find that the first item in the test…

Given significant changes to legislation, practice, research, and instrumentation, the purpose of this study was to examine the course on cognitive assessment in school psychology programs and to describe the (a) structure, (b) instructional strategies, (c) content, and (d) interpretative strategies taught to school psychology graduate students.…

The current study aims to examine the way in which teachers' and children's perceptions about their relationships influence children's emergent literacy skills. Participants were 913 children and 114 kindergarten teachers within 72 preschool centers from Greece. The measures used were the Student-Teacher Relationship Scale (STRS), the Child…

Goals: This study examined: (a) crystallized/fluid intelligence trajectories of adolescents and adults with Down syndrome; and (b) the contribution of endogenous (health, activities of daily living--ADL) and exogenous (cognitively stimulating leisure activities) factors on adults' intelligence with age. Method: Four cohorts (N = 80) with Down…

Purpose: Prior studies report conflicting descriptions of the relationships between phonological awareness (PA), vocabulary, and speech perception in preschoolers with speech disorders. This study sought to determine the nature of these relationships in a sample of school-aged children with residual speech sound errors affecting /[voiced alveolar…

African Americans experience more than double the prevalence of low birth weight (LBW)/premature birth compared to their Caucasian counterparts, reflecting a public health crisis and a significant social justice concern. However, there is a paucity of LBW outcome studies in African American samples. There are even fewer that investigate…

Research supports the efficacy of intensive literacy instruction for children with moderate intellectual disabilities and Down syndrome (DS). However, much of the literature features measures closely aligned with evaluated interventions. Despite their increasing role in instruction, curriculum-based measures (CBM) are rarely featured in reading…

The current study aimed to identify the level of emotional intelligence of outstanding students at the College of Education, Al Ain University (AAU), the United Arab Emirates, and their counterparts at Princess Nourah University (PNU), in the Kingdom of Saudi Arabia. A sample of 77 students was selected from both universities, of whom 41 students…

Purpose: The purpose of the study was to evaluate implicit learning in children with developmental language disorder (DLD) by employing a visual artificial grammar learning task. Method: Thirteen children with DLD and 24 children with typical language development between the ages of 8 and 12 years completed a visual artificial grammar learning…

The acquisition of vocabulary and narrative comprehension are key abilities for children's literacy development and to potentiate cognitive and academic skills from early ages. The aim with this study was to analyse the effects of a 6-week integrated active-lessons programme based on playful games, vocabulary, and narrative comprehension.…

The main goal of this study is to examine the differences between school-aged children with different chronotypes who are only children or have a sibling in the household, regarding their sleeping habits and performance in intelligence tasks. The main measures used were Chronotype Questionnaire for Children and Raven's Coloured Progressive…

We explore the cognitive skill gap between the adult population in Spain and in the rest of European Union countries using the Program for the International Assessment of Adult Competencies. We find that differences in schooling account for about a third of the average difference in cognitive test scores, whereas differences in socioeconomic…

Relatively few studies have directly examined children's memory of object-based spatial structure of room-sized environments. The current study investigated how children remember the spatial structure of a room, and the role of pictorial working memory (WM) and different testing perspectives in this process. In Experiment 1, 80 children aged 5 to…
