In table 3 the emotional intelligence (EI) parameters of mothers and fathers are shown. It is found out that general EI of fathers is slightly higher than mothers one. It is known that women’s emotional reactivity is higher than this parameter of men (Nikolaeva and Merenkova, 2012). But exactly EI is the tool of emotion’s management. Then we have analyzed the heart rate variability of children during two situations: background, when child was sitting quietly and during answering the experimenter’s questions (experimental load). The independent variable “IHP” influences just one dependent variables of background part of the experiment- index vegetative balance (Tabl.4). This parameter shows the balance between of the sympathetic and parasympathetic parts of autonomic nervous system.
