Moral development is necessary for the successful socialization of the individual. The mirror neuron system plays an important role in forming prosocial moral behavior in children, its activity being apparent as changes in the pattern of EEG sensorimotor rhythms. The aim of the present work was to identify the features of EEG reactivity on observation of neutral and pro- and anti-social actions in young children with different levels of moral judgment. The study involved 51 children aged 17–42 months. The extents of moral judgment were assessed using a game technique with presentation of neutral, prosocial, and antisocial situations. On first presentation of the actions of a neutral character, not accompanied by any morally loaded context, the amplitudes of the μ and β rhythms were found to be significantly lower in the group of children with a low level of moral judgement than in children with higher values for this indicator. Observation of a positive social action in children with a high level of moral judgment produced desynchronization of the sensorimotor β rhythm, while synchronization was seen in children with a low level of moral judgment. These differences reached the level of statistical significance in leads Fz and C4. Observation of an antisocial action did not cause significant changes in sensorimotor EEG rhythms in children of the two groups. It is suggested that sensorimotor EEG rhythm reactivity in children is largely related to the level of formation of moral judgment and the ability to identify with the character performing socially significant actions.
