reduction in statistical power for detecting less robust effects, the current patient sample was reasonably large compared to sample sizes of many other studies. Also, the current study included a particularly well-matched sample of healthy controls. Although patients responded more slowly than healthy controls, their performance accuracy during these less-demanding target detection tasks was more than adequate and on par with those of healthy adults. The well-preserved, highly-comparable CSD component structure in patients also bolstered the assumption that task disengagement was not a concern.
