The Relationship between Psychological Characteristics and Auditory Event-Related Potentials in Persons with Aggressive Behavior

<p>In the research aimed to investigate the psychophysiological mechanisms of propensity to aggressive behavior, the auditory event related potentials have been studied (P50 component and its inhibition, P300 component) in persons prone to criminal aggression. A correlation analysis of the event-related potentials and experimental psychological assessment was carried out. It was found that in persons prone to aggressive behavior, the sensory gating at the early stages of information selection is impaired, the effectiveness of inhibition processes is reduced, these deviations are associated with aggressive scores only in schizophrenia. In specific personality disorders, aggressive scores negatively correlate with the latency of P300. In mentally health and in mixed personality disorders, there was no relationship between event related potentials and aggressive scores, however, in mentally healthy individuals, there is a negative correlation of self–control with P300 amplitude, in persons with mixed personality disorders - a negative correlation of self-control with P300 latency, a negative correlation of P50 inhibition with anxiety.</p>
