Following up a marginally significant interaction Cognitive Demand * ADHD on target-N2 amplitude ( F 1,68 = 3.323; p = .073; η 2 p = .047) showed that children with ADHD (ADHD-only and ADHD+autism) had reduced target- N2 during high-demand trials ( M = −2.987 μV; SE = 0.344 μV), compared to children without ADHD (NT and autism-only: M = −4.043 μV; SE = 0.387 μV; p = .048).
