According to the current psychological view, the behavior of children and adolescents, in addition to the influence of congenital factors, is a reflection of the bio-psycho-social stimuli received by the individual, and the influence of these stimuli leads to their corresponding behavior patterns, among which there are violent behaviors or tendencies; there is also the fact that children and adolescents, because of the limitations of social cognition and curiosity, cannot understand that behaviors that make them happy or can avoid unpleasant behaviors can be harmful to others The causes of violence in adolescents are There are five main causes of violent tendencies in children and adolescents: 1. Children copy and imitate the way their families deal with problems and acquire “violence” from their parents. 2, the family atmosphere of indifference, repression and other relationship disharmony, children and parents can not communicate effectively. The child’s inner anxiety and repression have nowhere to be released, so these children behave well at home, but outside the home to violence or alternative ways to vent the distorted psychology. 3, by the negative impact of exaggerated violent images and depictions on television, the Internet, etc., because the child is limited by psychological development, can not be well cognitive, easy to imitate learning. 4, the child’s physical traits and other special reasons (such as some mental disorders, character disorders) caused by aggressive behavior. 5, the child’s peer violence will also bring adverse effects for them. In the world of children, it is more about the principle of happiness, so the education of children and adolescents should start from the very birth. The most important way how to go about detecting violent tendencies in children and adolescents is to get in close contact with the child, observe carefully, participate in the child’s feeding, games, education and the child’s social interactions in order to detect abnormal behaviors in time so that they can be corrected. As a parent, what can you do? First, be psychologically prepared to care for your child from the bottom of your heart, recognize the difficulties and complexities of child rearing, the need to learn many knowledge and skills, and adapt to the change in role. Second, never think that your child is still young and has no memory, but in fact the education of your child begins at birth. Some studies have found that children have memories from birth, and what they are allowed to see or come into contact with will be stored in their memories and affect them for the rest of their lives. Therefore, parents need to maintain a good image at all times, pay attention to their words and actions, strengthen their own cultivation, deal peacefully and rationally with the problems between husband and wife, as well as with the interaction between them and their children, and treat some of their children’s behavior rationally. Third, try to guide the child and direct the child’s curious actions to be recognized and accepted by society. If a child is found to have psychological problems, parents must not assume that the child will naturally get better when he or she grows up, and need to seek help from professional institutions in a timely manner.
