title: Brain stem auditory evoked potentials and personality.
abstract: The investigations involved 20 schizophrenic male patients and 50 healthy male controls. Only those who had good brain stem auditory evoked potentials (BAEP) replicability and clearly visible components were accepted. BAEP were recorded ipsilaterally and contralaterally to the click rarefaction stimuli. Two averagings of 2048 repetitions were superimposed. All the subjects whose BAEP were accepted completed the Eysenck Personality Questionnaire (EPQ). A positive correlation between the P dimension of personality and I-II interpeak conduction time was found in both groups. The correlation of the P score with BAEP latencies increased rapidly from I to II ipsilateral and III contralateral components and then gradually decreased with successive components.
