Abstract

We investigated the physiological and behavioral characteristics of children aged 9—10 years during a neurophysiological experiment aimed at performing tasks based on the Sternberg paradigm. A statistical analysis of the stability of wave rhythms as well as a correlation analysis between them and the average reaction time was carried out, based on which a biomarker of the efficiency of the working memory task was found.
