This is a turning age when puberty occurs. It is also called critical, because the child can become uncontrollable.
The German philosopher and psychologist E. Spranger considered this age a period of growing into culture. He divided the course of adolescence into three categories.
The first type is violent, harsh and rebellious. There is a kind of rebirth, and a completely different adult with different qualities grows out of a teenager.
The second type proceeds smoothly. The child gradually joins adult life, acquiring the features of an adult without cardinal personal changes.
The third type is represented by teenagers who are actively engaged in self-education. They independently cope with the difficulties of transition into adulthood, showing an iron will.
At a transitional age, a teenager becomes aware of himself as a person.
Puberty leaves its mark on this process. Children become overly sensitive and vulnerable, excitable and even aggressive. They can hate themselves and the whole world around them, reach out to the mysterious and incomprehensible. All forbidden things have a special attraction for them.
This unstable period ends soon and the child lights up with optimism. Melancholy can be replaced by an increased craving for knowledge and efficiency. Teenagers make global plans and undertake to solve impossible tasks. Child psychology is being displaced naturally.
