The original version of this article unfortunately contained a mistake. The authors discovered an error in the processing of the ERP data included in originally published manuscript. All of the data has been reprocessed using average referencing. The primary findings in our original paper highlighted diagnostic group differences in ERPs from the 400–600 ms range but no group differences from 600–1000 ms. We now report significant differences from 600–1000 ms and also a trend for significant group differences from 400–600 ms. One correlation between ERP responses to neutral pictures during the 400–600 ms window and BAS drives scores is no longer statistically significant, however this does not alter the conclusions made in the paper. A list of corrected results are provided below, as well as a revised Table 1 and Fig. 2. Please see the online supplement for a completely edited results section of the manuscript. The original article has been corrected.
