NEUROPHYSIOLOGICAL MARKERS OF PRECISION OF INFORMATION PROCESSING
We investigated the neurophysiological features of the process in the easier and more difficult task in the oddboll paradigm. The subjects were previously divided into more or less accurate ones using the Kogan test. The purpose of the study was to study the neurophysiological differences of event-related potentials (ERP) between the accurate and inaccurate subjects. The main condition for identifying of neurophysiological markers of information processing accuracy was the use of different sensory modalities and non-coincidental mental operations for leveling of secondary factors of the cortical regulation. In the Kogan test there was a visual search of the picture whish was the most similar to the sample. In the oddboll auditory paradigm test there was suggested to press the button (discrimination) at the appearance of the rarer significant tone. The task was carried out with the simultaneous registration of the EEG. A statistical analysis of the ERP average amplitudes was performed within 500 ms after the significant tone presentation. The comparison the ERP in accurate and inaccurate subjects in the difficult task allows to observe the amplitude differences for later stages of information processing. The author discusses a possible role of the behavior control, internal speech, awareness and mindfulness in providing of more accurate information processing.
