Background: The aim was to explore the executive function profile of a group of Mexican people with Down syndrome (DS) aged 12-30 years during the COVID-19 pandemic. Aim: To analyse the relationships between mental, chronological age and eight domains of executive function. Method: Participants were 42 people with DS with a chronological age (CA)…

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'…

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 =…

Individuals diagnosed with autism spectrum disorder (ASD) are more likely to have suicidal thoughts and behaviors. However, little research delineates the temporal and mechanistic associations between potential risk factors and suicidality in autistic individuals. We assessed 129 autistic and 121 age-matched and sex-assigned-at-birth-matched…

Autistic individuals are at significantly higher risk of suicide than non-autistic individuals, with transition-aged youth at potentially the highest risk. While lower executive function (EF) skills have been significantly associated with suicide risk in other clinical samples, the link between EF and suicidality has not yet been examined for…

Dysexecutive syndrome has been consistently reported in children and adolescents with autism spectrum disorders (ASD). Particularly, impairments have been documented in working memory, inhibition, and mental flexibility. However, the relationship between executive impairments and intellectual functioning is far from clear in this population. This…

Item recognition and temporal order memory follow different developmental trajectories during middle childhood, with item recognition performance stabilizing and temporal order memory performance continuing to improve. We investigated the potential unique role of individual executive functions on item recognition and temporal order memory during…

This study examined the factor structure of executive control throughout elementary school, as well as associations between executive control abilities in preschool and elementary school. Data were drawn from a longitudinal study of executive control development in a community sample of children (N = 294; 53% female, 47% male) oversampled for low…

This study examined auditive and visual working memory and metacognitive knowledge in 92 gifted children (aged between eight and twelve), utilising a pre-test-training-post-test design, known as the cognitive training design. This approach was used to examine the working memory and metacognitive knowledge of gifted children concerning the…

The objective of this research was to develop robust predictive models of the gains in working memory (WM) and fluid intelligence (Gf) following executive attention training in children, using genetic markers, gender, and age variables. We explore the influence of genetic variables on individual differences in susceptibility to intervention.…

Intellectual performance is highly heritable and robustly predicts lifelong health and success but the earliest manifestations of genetic effects on this asset are not well understood. This study examined whether early executive function (EF) or verbal performance mediate genetic influences on subsequent intellectual performance, in 561 U.S.-based…

Objective: We investigated the right Superior Frontal Gyrus (right-SFG) and Anterior Cingulate Cortex (ACC) in children with ADHD and their clinical relevance with Executive Function (EF) and ADHD symptom severity. Methods: About 26 children with ADHD and 24 typically developing children (TDC; 7--16 years) underwent Magnetic Resonance Imaging…

Recent studies indicate that premature children are at risk for difficulties with cognitive development and have increased incidence of ADHD as well as other behavioral disorders. Although the exact mechanism accounting for these children's neuropsychological abnormalities is unknown, there is evidence to suggest that the cognitive and behavioral…

Anxiety in Children can develop into pervasive disorders in adulthood if not treated. Research shows dysfunctional Executive Function (EF) and anxiety are both shown to have a negative impact on math achievement in children and adolescents (Trezise & Reeve, 2018; Kalaycioglu, 2015; Owens, Stevenson, Hadwin & Norgate, 2012). Chung, Weyandt,…

One of the best-established findings in intelligence research is the pattern of positive correlations among various intelligence tests. Although this so-called positive manifold became the conceptual foundation of many theoretical accounts of intelligence, the very nature of it has remained unclear. Only recently, "Process Overlap…
