Effect of development of cognitive functions on psychophysiological indices of the orienting reaction in a child

Some parameters of the base-line electrical activity of the brain of a 4-year-old child and their changes under conditions of intensive intellectual training concerning the ability for visual modelling have been studied. It is shown that progressive development of the cognitive function results in trasfer of the cerebral mechanisms of the orienting reaction to a new and more progressive level of structural-functional organization, and in more intensive orienting-researching activity on the part of the child.
