    Grand average ERPs to relevant nontargets for load1 (gray curve) and load3 (black curve) stimuli at Cz. Only the control children demonstrated significant main effects of Load pointing to a search-related negativity (SRN). In the ADHD group, the factor Load elicited high effect sizes in both the relevant and irrelevant category, but did not reach significance.
