ERP Parameters of the Formation of the Skill of Distinguishing Short Time Intervals

Abstract

A method including registration of an electroencephalogram (EEG) has been developed and tested to study the processes of acquisition/improvement of a skill. The method is based on the Signal Detection Theory. The experimental task was to distinguish of short time intervals. The psychophysiological data of 10 study participants (learning group) from the total sample (N = 28) were analyzed. Typical components of event-related potentials (ERPs) during the presentation of the estimated signal were identified. Time-amplitude characteristics of the components were analyzed. The results obtained are discussed from a system-evolutionary approach.
