Mean startle blink magnitude and skin conductance changes when viewing specific pleasant, neutral, and unpleasant picture contents, across healthy comparison subjects, prodromal patients, first-episode schizophrenia patients, and chronic schizophrenia patients. Picture contents are ordered by rated arousal within pleasant (right to left: low to high arousal) and unpleasant (left to right: low to high arousal) categories.

¹For skin conductance data, healthy comparison subjects (n= 70), first-episode patients (n=30), chronic patients (n=29).
