The research examines the structure of interrelations of brain event-related potentials to behavioral measures and temperament dimensions during an attentional task. Three temperament questionnaires were used: Eysenck Personality Inventory, Strelau Temperament Inventory and Rusalov Structure of Temperament Questionnaire. Event-related potentials were recorded under the active auditory oddball paradigm. The stimuli (85 dB, 1050 and 1000 Hz sinusoidal tones as targets and non-targets correspondingly) were easily discriminated by all participants. A complex framework of interrelations between temperament and personality dimensions, behavioral measures and event-related potentials was found. Particularly, P3 amplitude was negatively related to the number of response omissions. Emotionality was positively correlated to P2 and N1-P2 complex amplitude. Extraversion together with Mobility of Nervous Processes was negatively related to the amplitude of N1-P2 complex, and together with Social Ergonicity it was negatively related to N2 latency. The results demonstrate that Extraversion tends to be associated with both intensity and temporal aspects of temperament and hint at the importance of using multidimensional approach in temperament studies.
