Event-related potential amplitudes arranged by measure and effect. Early posterior negativity (EPN) amplitudes are to the left, late positive potential (LPP) to the right, valence effects at the top, and block effects at the bottom. Healthy control is in purple, schizophrenia (SZ) in black, schizoaffective disorder (SAD) in dark gray, bipolar I disorder with psychotic features (BDP) in light gray, and bipolar I disorder without psychotic features (BDNP) in teal. Line plots are shown with 1 SE.
