Correction

In the March 2011 article “Overactive Error-Related Brain Activity as a Candidate Endophenotype for Obsessive-Compulsive Disorder: Evidence From Unaffected First-Degree Relatives” by Anja Riesel, Dipl.-Psych., et al. (Am J Psychiatry 2011; 168:Original article: 317-324. doi:10.1176/appi.ajp.2010.10030416), the scaling of the y axes in part A of Figure 2 should have been inverted. In event-related potential research, negative is usually printed upwards so for Figure 2A, −5 should have been depicted upwards. In the online version, the scaling of the y axes has been corrected.
