Comparison of different methods for eliciting informative reports in terms of their discrimination performance for schizophrenia. Dream and Negative image reports are more discriminating than long-term memories. a Schizophrenia diagnostic classification using 5 connectedness attributes (E, LCC, LSC, LCCz, and LSCz) using 6 time-limited memory reports. Only dream and negative image reports classified schizophrenia group vs. Bipolar and Control group with AUC > 0.75 and accuracy > 75%. b Connectedness attributes from dream and negative image reports compared between groups. c LSC normalized by word rate from dream and negative image reports compared between groups d The z-scores of the original graph connectedness relative to the random graph distributions (LCCz and LSCz) from dream and negative image reports compared between groups. Bar plots indicate of median values and error bars indicate standard error of the mean (s.e.m); Kruskal–Wallis tests: p value for dream/negative image reports indicated in each title; Wilcoxon–Ranksum tests (Bonferroni corrected for 8 comparisons (4 comparison for each 2 memory reports—SxB, SxC, Sx(B + C), and BxC)): # means p < 0.0063—Schizophrenia vs. Bipolar and Control groups, asterisk means p < 0.0063—Schizophrenia vs. Bipolar or Control groups
