The Relationship between Concordance of Some Personality Dimensions and Visual Evoked Potentials

This research is aimed to investigate the possible difference in ERPs between subjects with high and low concordance of nine personality dimensions: extraversion, neuroticism, psychoticism, strength of excitation, strength of inhibition, mobility, impulsiveness, adventurousness and empathy. Applying standard visual oddball paradigm in two blocks, early and late EP-components are measured: N1, P2, N2, P3 and SW in a sample of N = 54 psychology students (all females, averaged age of 20 years). Results showed significant difference in measured ERPs, except in slow wave. The low concordance group showed significantly lower EP-amplitudes and longer EP-latencies of N1, P2, N2 and P3. Also, significant correlation was determined between year of study and personality concordance, where students of higher years of study showed higher levels of concordance. The findings were discussed in the frame of an important relationship between evoked potentials and concordance of personality dimensions, in this case as a part of ongoing maturation processes.
