Grand averaged P3b amplitude to targets at P7. Topography depicts mean P3b amplitudes across the P3b time window (320–400 ms) in control subjects. (A) SZ had reduced peak amplitudes compared to HC (FDR corrected p < .01). (B) There were no observed group differences in peak P3b amplitudes between BP, BPRel and HC at P7 alone.(C) P3b amplitudes were positively associated with average dˊ across all five groups (r(2 2 5) = 0.37, FDR corrected p < .01). (D) P3b amplitudes were positively associated with the number of SimDiff errors in BP (r(25) = 0.619, FDR corrected p < .01). * indicates p < .05 | ** indicates p < .01.
