Objective: ADHD has been associated with persistent problems of working memory. This study investigated the efficacy of an intensive and adaptive computerized working memory treatment (CWMT) at behavioral and neural levels. Method: College students ( n = 89; 40 females) with ADHD were randomized into a standard-length CWMT (45 min/session, 25 sessi...

Article
Full-text available
Individuals with Attention-Deficit Hyperactivity Disorder (ADHD) are often characterized by deficits in working memory (WM), which manifest in academic, professional, and mental health difficulties. To better understand the underlying mechanisms of these presumed WM deficits, we compared adults with ADHD to their peers on behavioral and neural indi...
Article
Background Attention-deficit/hyperactivity disorder (ADHD) is proposed to be a neuropsychologically heterogeneous disorder that encompasses two distinct sub-groups, one with executive function (EF) deficits and one with delay aversion (DA). However, such claims have often been based on studies that have operationalized neuropsychological deficits u...
Article
Attention Deficit / Hyperactivity Disorder (ADHD) and Chronic Tic Disorder (CTD) are two common and frequently co-existing disorders, probably following an additive model. But this is not yet clear for the basic sensory function of colour processing sensitive to dopaminergic functioning in the retina and higher cognitive functions like attention an...
Article
Background: A body of literature has emerged that links inattentive symptoms of attention deficit hyperactivity disorder (ADHD) to poor academic achievement. Major variation across studies renders conclusions about this relationship complex. Purpose: This review will provide a qualitative synthesis of these studies that (1) use community samples an...

Article
Full-text available
Although universal screening for mental health difficulties is increasingly recognized as a way to identify children who are at risk and provide early intervention, little research exists to inform decisions about screening, such as the choice of informants and the type of information collected. The present study examined the incremental validity o...

The brain uses 20% of the body’s energy. The processes delivering that energy to neurons can fail in numerous ways. The neuroenergetics theory draws out the implications of failure in the supply chain between blood capillaries and neurons. The theory is implemented as a diffusion model that yields response-latency distributions, error rates, and ot...

Selective mutism (SM) is a childhood disorder characterized by failure to speak in social situations, despite there being an expectation to speak and the capacity to do so. There has been a focus on elucidating the differences between SM and anxiety disorder (ANX) in the recent literature. Although children with SM exhibit more symptoms at school t...
