The present study explores the relationships among executive functions (EFs) (working memory, inhibition, and cognitive flexibility), number of friends, friendship stability and friendship quality in neurotypical (NT) children and peers with attention deficit/hyperactivity disorder (ADHD) or dyslexia. The participants were 192 children…

Objective: ADHD is a neurodevelopmental disorder that impacts pragmatic communication abilities in children, including their understanding of verbal irony. This study aims to investigate whether adults with ADHD experience similar challenges in interpreting ironic statements, and to examine the role of executive attention abilities in accounting…

Objective: Stimulant medications are the main treatment for Attention Deficit Hyperactivity Disorder (ADHD), but overall treatment efficacy in adults has less than a 60% response rate. This study aimed to identify neural and cognitive markers predictive of longitudinal improvement in response to stimulant treatment in drug-naïve adults with ADHD.…

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is characterized by inattention, hyperactivity, and impulsivity; however, other executive function dysregulation is common, including inhibition and working memory. This study aims to identify CT differences based on executive function performance in individuals with and without ADHD.…

Executive function is deficient in individuals with ADHD. Playing a musical instrument has been shown to improve executive functions. This study examined if participants with ADHD perceived a connection between playing an instrument in a music ensemble and improved executive functioning, as well as improved ADHD presentations. The research design…

Introduction: As a result of similar behavioral manifestations across populations, the conspicuous diagnostic confusion of high intellectual ability (HIA) and Attention Deficit Hyperactivity Disorder (ADHD) is often reported. Approaching Executive Functions as underlying processes can assist in distinguishing the two conditions. The principal aim…

Physical activity (PA) benefits children's cognition, in particular executive functions (EF). Children with Attention Deficit Hyperactivity Disorder (ADHD), Reading Difficulties (RD) and co-occurring ADHD/RD have low levels of PA and difficulties with EF. This study evaluated a PA programme to determine recruitment, attrition, feasibility (e.g.…

Cognitive flexibility (CF) is an executive function component related to the ability to flexibly shift amongst multiple incompatible perspectives or descriptions of an object task. However, whether CF enhances the narrative discourse comprehension of students with attention-deficit hyperactivity disorder (ADHD) during surface semantic meaning…

Nonverbal Learning Disability (NLD) has been the focus of four decades of neuropsychological research. However, it has yet to be included as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (i.e., currently in its fifth edition, DSM-5, American Psychiatric Association, 2013). Many of the characteristics associated…

Few qualitative studies have focused on the experiences of students with attention-deficit/hyperactivity disorder (ADHD) pursuing postsecondary education, and in particular, how their academic difficulties manifest themselves. This study provides a better understanding of how ADHD affects students in their studies. In-depth interviews were…

The diagnostic utility of the Woodcock-Johnson III Tests of Cognitive Abilities and Clinical Clusters was assessed in a sample of 52 children (26 Attention Deficit/Hyperactivity Disordered (ADHD) and 26 matched controls). Multivariate analysis of variance followed by post-hoc testing and d-ratios yielded some statistically significant and…

Children with ADHD are often described as experiencing deficits in executive function. Two key areas of concern are inhibition, the ability to refrain from a dominant response when needed, and updating, the ability to revise or update incoming information. The purpose of this manuscript is to combine disparate lines of research to help establish a…

This study was designed to investigate the frequency with which students identified as having a Specific Learning Disability (SLD) and a Specific Learning Disability (SLD) combined with Attention Deficit Hyperactivity Disorder (ADHD) are further assessed for deficits of executive function and working memory. Data were collected and analyzed from…

Objective: The aim of the study is to design and evaluate the Strategy Awareness and Use Questionnaire to estimate students' awareness and use of strategies that optimize control of attention and/or compensate for stress on an executive system due to environmental and/or neurobiological influences. Participants: One hundred and forty-eight…

The primary objective of this study was to examine the effects of the Cogmed training program on working memory among youths 7 to 13 years old, with attention deficit/hyperactivity disorder (ADHD) type and comorbidity controlled for. A secondary objective was to examine the generalization of effects to ADHD symptoms, nonverbal reasoning,…
