Note: Using procedures detailed by Uitenbroek (1997), we maintained an experiment-wise significance level of p<.05 using a partial Bonferroni correction in which we accounted for the average correlation among cognitive variables. The average Pearson r among these variables was 0.28 for controls and 0.38 for patients with first episode psychosis. The partial Bonferroni-corrected p value that defined significance was <0.0076 for controls and <0.0099 for patients with SZ+
