Lateralization types in children and neurophysiological foundation of individual ability to learn

Right-handed 2-7-years-old children after the determination of leading hand in various kinds 01 bimanual activity were divided into 2 groups: with higher level of right-handedness (I) and with lower level of it (II). Correlation analysis of EEG shows that children of two groups have two types of function lateralization-strict lateralization expressed in left-hemispheric asymmetry in all cases of verbalization of tactile perception of an object (I group), and changing lateralization when the sign of asymmetry changes according to emotional importance of percepted object (II group). The children of II group have higher level of speech thinking, are more active emotionally, have higher ability to learn. The right-handedness increases in preschoolers and decreases in schoolchildren.
