Influence of the concordance of temperament questionnaires data on the properties of the event-related potentials
Despite the fact that widely used temperament questionnaires (for example, Eyesenck's EPI, Strelau's Pavlovian temperament survey) are based on different theoretical approaches, their dimensions are usually interrelated in a strict way, i.e. their scales correlate with each other in a regular manner (Rusalov 1990, Strelau 2009). But this is not always the case, and for some subjects dataobtained by different questionnaires give discordant results (Ramendik, 2010, 2008). The nature of this irregularity is unclear, and the aim of the present study was to investigate the electroencephalographic correlates of such discordance.
