Increased reaction time variability in attention‐deficit hyperactivity disorder as a response‐related phenomenon: evidence from single‐trial event‐related potentials

Abstract

These data suggest that the increased ISV found in ADHD could be associated with response-end, rather than stimulus-end processes, in contrast to prevailing conceptions about the endophenotype. This mental chronometric approach may also be useful for exploring whether the existing lack of specificity of ISV to particular psychiatric conditions can be improved upon.
