This project examined the unique predictive validity of parent ratings of toddler-age aggression, oppositionality, inattention, and hyperactivity-impulsivity to academic achievement at school-age in a sample of 566 high-risk children and families. The study also investigated potential indirect effects of the Family Check-Up on school-age academic…

Objective: We sought to examine preliminary results of brain alterations in anterior cingulate cortex (ACC) in treatment-naive adults with ADHD. The ACC is a central brain node for the integration of cognitive control and allocation of attention, affect and drive. Thus its anatomical alteration may give rise to impulsivity, hyperactivity and…

Objective: This study examines the difference between college students with and without Attention Deficit/ Hyperactivity Disorder (ADHD) in regard to their work performance. Method: A series of ANOVAs analyzed group differences in symptoms experienced at work. The independent variable was group (i.e., ADHD, Controls). The dependent variables…

This study examined effects of integrating mindfulness practices into the 5th grade curriculum to improve attention-to-task, including inattention and executive functioning, hyperactivity/impulsivity, and social relations. As academic requirements become more rigorous, students have been expected to demonstrate increased skills in…

This study investigated the effects of response rate and attention focusing on performance of ADHD, clinical-control (CRNA) and non-clinical control children in response inhibition tasks. All children completed the "Go-NoGo" task, a computer-based task of attention and impulsivity. Focused attention on this task was manipulated using a priming…

Theoretical accounts of attention-deficit/hyperactivity disorder (ADHD) posit a prominent role for problems in response inhibition (Nigg 2006). A key avenue for impulsivity in children with ADHD is inappropriate language expression. In this study, we sought to determine whether poor inhibitory control affects language production in adolescents and…

Trained classroom observers used the Direct Observation Form (DOF; McConaughy & Achenbach, 2009) to rate observations of 163 6- to 11-year-old children in their school classrooms. Participants were assigned to four groups based on a parent diagnostic interview and parent and teacher rating scales: Attention Deficit Hyperactivity Disorder…

This study investigated the movement preparation (reaction time) and movement execution (movement time) of children with and without ADHD by manipulating the uncertainty of occurrence. Participants performed a seated lower extremity choice response time protocol, which contained either 10% catch trials or 30% catch trials along with 27 empirical…

The goal of the current study was to test whether deficits in processing speed (PS) may be a shared cognitive risk factor in reading disability (RD) and Attention Deficit/Hyperactivity Disorder (ADHD), which are known to be comorbid. Literature on ADHD and RD suggests that deficits on tasks with a speeded component are seen in both of these…
