Psychophysiology, Volume 63, Issue 9, September 2026.ABSTRACT Attention‐deficit/hyperactivity disorder (ADHD) and obsessive‐compulsive disorder (OCD) are common psychiatric disorders that may be differentiated by neurocognitive measures and electrocortical indices of performance monitoring. Increased reaction time variability (RTV) is a consistent finding in studies of ADHD. The error‐related negativity (
