Top‐down volitional command of eye movements may serve as a candidate endophenotype of ADHD, an important function underlying goal‐directed action in everyday life. In this twin study, we examined the relation between performance on a response inhibition eye‐tracking paradigm and parent‐rated ADHD traits in a population‐based twin sample. We hypothesized that altered eye movement control is associated with the severity of ADHD traits and that this association is attributable to genetic factors.
