Testing the Cursor Trajectory and Emotion of Potential Adult Attention-Deficit/Hyperactivity Disorder in the Attention Network Test

By Stanley W Sun


Attention-deficit/hyperactivity disorder (ADHD) is a common and underdiagnosed mental disorder that affects more than 1 in 10 (11%) of U.S children, and about 60% of children with ADHD become adults with ADHD (Visser et al., 2014; Barkley, Fischer, 2010). The diagnostic methods used today are designed for adolescents; as a result, primary care physicians encounter significant difficulties when diagnosing ADHD in adults. In the proposed project, I aim to clarify main characteristics of adult ADHD by analyzing their symptoms with respect to a group of higher order cognitive abilities known as executive function by scrutinizing the relationship among impulsivity, emotion, and motions. It is known that ADHD patients have a noticeable deficiency in the ability to inhibit emotions, also known as emotional impulsivity. Research indicates that people’s emotional states are reflected in their body motions. In this regard, I hypothesize that executive control is manifested in body motions (e.g., directed hand movement) in adult ADHD patients. To test this hypothesis, I will measure the movements of the computer cursor in the go/no-go task, and compare the cursor movement patterns of those who are vulnerable to ADHD and those who are not. If found successful, it would help primary care physicians better diagnose ADHD for adults
