Dr. Patel conducted an investigation to determine whether having Obsessive-Compulsive Disorder (OCD) compared to Attention Deficit Hyperactivity Disorder (ADHD) influenced an individual's working memory capacity. Working memory capacity was measured using a computerised Dual N-Back task, which produced a performance score ranging from 0 (very poor working memory) to 100 (exceptional working memory).
