Manifestations of Temperament and Perception in Auditory Evoked Potentials
The aim of this paper is to study manifestations of temperament in auditory evoked potentials (EP) during the odd-ball paradigm. Three questionnaires were used; Pavlovian Temperament Survey (PTS), Structure of Temperament Questionnaire (STQ), Eysenck Personality Inventory (EPI). All subjects were divided into two groups with high (I) and low (II) concordance between the questionnaires’ data. Amplitudes of N2 wave and of N2-P3 complex were found to be statistically different in the two groups. In group I, a number of significant relations between questionnaires' dimensions and EPs parameters were shown; in group II such relations were much less numerous. The data obtained show that temperament is determined by brain processes of perception and attention, and also hint at the existence of individuals with fundamentally different patterns of psychophysiological manifestations of temperament.
