Adolescence is the period of development and mental advancement that occurs between the onset of puberty and the achievement of physical development and emotional. Although young women undergo more dramatic physical changes during adolescence than young men, they tend to reach puberty earlier and take less time to develop. Immaturity in girls begins around the age of eleven and continues until about sixteen. In young men, the same period begins around the age of thirteen and continues until about eighteen. After about fourteen years, men are normal, heavier and taller than women. The film Thirteen, directed by Catherine Hardwicke, presents a correct and important perspective on the experience of post-millennial teenagers and also shows many problems that teenagers face in today's society, such as pressure peers, adolescent sexuality and drug use. adolescence does not feel safe and is not sure of itself. They want to fit in and belong. If they don't, they consider themselves abnormal. Children seek to become independent from their parents and immerse themselves in their own social environment beginning in adolescence. According to psychologist Erik Erikson, “Peer groups meet the adolescent's need for validity and acceptance and provide space and opportunities for exploration and experimentation. » The same goes for protagonist Tracy, as in order for her to be accepted by Evies, she stole a handbag from an old lady and then went on a shopping spree. Tracy explored and experimented with many things with her new peer group, but from there it all went downhill as Tracy experienced and reacted to a variety of pressures and situations that are not uncommon.... .. middle of paper...... For a teenage girl, her other, more dangerous behavior could be a sign for less delicate teens to stay as far away as possible under the circumstances. It's the turning point that cements the girls' friendship and sets Tracy on an intense downward path, toward drugs, alcohol and sexual exploration, shoplifting and a general transformation from innocent schoolgirl as a corrupt girl. Tracy did things like get her tongue and belly button pierced because that's what her new friend Evie had. If her friend took a drug, she tried it too. Thirteen describes social learning theory extremely well. She sees her friend's tips on how to attract men and steal, and she imitates what she thinks will help her fit in. This theory is all about imitating and following what you see being done. Thirteen is a great example of social learning theory.
