The spatial organization of the EEG and individual psychological characteristics

: The influence of cognitive styles (analytic versus synthetic style, rigid versus flexible cognitive control, impulsivity versus reflexivity, field-dependence versus independence) on the information brain processes was estimated by means of analysis of spatial organization of cortical electrical activity (48 derivations) in 40 right-handed subjects (aged from 18 to 40) during their realization of verbal and non-verbal tasks using successive and simultaneous processing modes. Modulation of the "cognitive axis" (activity of the left anterior and right posterior cortical areas) was revealed connected with the factor of task subjective difficulty, especially in case of simultaneous processing mode. The combination of the synthetic cognitive style and flexibility of the cognitive control may be thought of as being the most favourable for the activation of the "cognitive axis" and utilization of the left- and right-hemispheric information processing, especially in non-standard situations.
