Dr. O’Neill's Attention & Neuropsychological Development (ATTEND!) Lab studies Attention-Deficit/Hyperactivity Disorder (ADHD), a neurodevelopmental disorder that for many emerges early in childhood.  Although some children who show high levels of inattention and/or hyperactivity during preschool do not go on to develop ADHD, many do go on to receive an ADHD diagnosis at school age; for the majority of these children, ADHD persists through adolescence and adulthood with varying degrees of severity.  Given the high prevalence of the disorder, its chronicity, and associated functional impairment, better understanding of the factors that affect the course of the disorder is needed, as is the development of evidence-based interventions.


Dr. Sarah O'Neill is an Associate Professor of Psychology.  One line of her research focuses on the predictors of symptom severity and adaptive functioning among children and emerging adults with ADHD.  She is particularly interested in how neuropsychological factors interact with environmental factors to affect trajectories of ADHD over time.  The second arm of her work focuses on development and testing of non-pharmacological 

interventions for ADHD
