From the author: Violetta Vasilievna Mikhailovskaya. Child-parent relationships and aggressive behavior of preschoolers. The development of a child’s aggressive behavior is influenced by various family factors: the degree of family cohesion, closeness between parents and child, the nature of the relationship between brothers and sisters, as well as conflict or inadequate family parenting style. Children who have strong family discord, whose parents are distant and cold, are comparatively more prone to aggressive behavior. “Problem”, “difficult”, “disobedient”, “impossible” children, as well as children with “complexes”, “downtrodden”, “unhappy” - are always the result of destructive styles of family education. In recent decades, psychology has made a number of discoveries. According to L.B. Schneider, one of them is about the importance of the style of communication between an adult and a child. As the world practice of psychological assistance to children and their parents shows, even very difficult problems with children are completely solvable if it is possible to create a favorable climate of communication in the family. Russian psychologists L.S. Vygotsky; S.L. Rubinstein, P.Ya. Galperin, L.I. Bozhovich, V.S. Mukhina and others call social experience, which is acquired by the child throughout childhood, as the dominant aspect in personality development. In the process of assimilation of this experience, not only children acquire certain knowledge and skills, but their abilities develop and their personality is formed. It is with close adults that the child meets in the first stages of his life and it is from them and through them that he gets acquainted with the world around him, and later comprehends the complex system of human relationships (Dubrovina I.V.). Therefore, factors of family upbringing are currently identified as the central underlying cause of aggressiveness by almost all researchers of this problem. Family parenting style plays a significant role in shaping a child's personality. Both authoritarian and influential parents are very demanding of their children, and they expect their children to behave properly and obey established rules. However, authoritarian parents also expect their children to accept their judgment, values, and goals without question. On the contrary, influential parents are more open in communicating with their children. Therefore, despite the fact that authoritarian and influential parents significantly control the behavior of their children, influential parents have less psychological impact on the child, unlike authoritarian parents. Research work on the topic “Child-parent relationships and aggressive behavior of preschoolers” included: observation of aggressive behavior of preschoolers, determining the characteristics of child-parent relationships through the eyes of a child, determining the characteristics of parental education. The study was conducted on the basis of the nursery school No. 2 in Minsk. The study sample consisted of 30 children, of which 15 were girls and 15 were boys. To conduct the study, the following methods were chosen as diagnostic tools: 1) observation of aggressive behavior of preschool children. “Program for monitoring aggressive behavior” (F. Petermann, U. Petermann) 2) projective method “Kinetic Family Drawing” (R. Burns, S. Kaufman) 3) questionnaire “Parent-Child Relationship” (I.I. Markovskaya) 4) methods of mathematical statistics: Pearson’s linear correlation coefficient, Student’s t-test (STATISTICS 6.0 program). In the course of the empirical study: 1. It was found that excessively strict parental control leads to emotional distress for the child in the family. The parent's strictness also causes an increased level of anxiety in the child. The manifestation of cooperation is negatively associated with the child's aggressiveness. Anxiety, on the contrary, has a higher level in children with increased aggressiveness. The study showed that parental anxiety.
