Sustained performance and regulation of effort in clinical and non‐clinical hyperactive children

Abstract

Deficits in sustained performance among ADHD children appear to be evident when long interstimulus intervals are used, and these deficits are related to poor regulation of effort. Further, the observed differences between ADHD children and normal controls do not appear to be a result of comorbid conduct problems. The non-clinical hyperactive children were more similar to the control group than to the ADHD group.
