Comparison of behavioral variables and electrophysiological features between SCZ and HC. Top left panel: Perceived intensities to different sensory stimuli. While the perceived intensities to nociceptive stimuli were significantly smaller for SCZ compared to HC, the perceived intensities to non‐nociceptive somatosensory and auditory stimuli showed no significant differences between the two groups. Top right, middle, and bottom panels: Event‐related EEG responses to different sensory stimuli in the time domain. Latencies and amplitudes of all LEP waves (i.e., N1, N2, and P2) were significantly different between SCZ and HC. In contrast, no significant differences between SCZ and HC were found in N2 latency, P2 latency, and P2 amplitude of SEPs and AEPs. Notably, for both SEPs and AEPs, N2 amplitudes were significantly smaller in SCZ than HC (*p < .05; **p < .01; ***p < .001; ns: not significant)
