The authoritarian style, as the name implies, refers to the ability of an adult to impose his will on the child in a threatening, judgmental and rigid way. This style can be adopted by parents or people who work with children, imposing an absolutist behavior. When planning to adopt this type of style, the individual must keep in mind that the child will behave in a fearful and shy manner, not revealing his true potential in any activity for fear of receiving reprisals, which will be adopted whenever the child does something unpleasant. . It is also important to keep in mind that the authoritarian style does not impose a relationship of friendship and respect between child and adult and can trigger situations of fear and anguish in the child.
