1.Resistance and Dependence Since junior high school students have developed a strong sense of adulthood and thus a strong sense of independence, they are reluctant to obey everything and do not want to listen to the opinions of parents, teachers and other adults, and are often in an emotional state of resistance to adults in their lives, from dressing and hats to their views on people and things. However, junior high school students are not completely free from the dependence on their parents in their hearts. The dependence on parents in childhood is more on emotion and life, while the dependence on parents in junior high school is on the hope of getting spiritual understanding, support and protection from parents. 2. Closedness and Openness Junior high school students who enter adolescence gradually close their hearts, their psychological life is richer, but they have less things to show outside. But at the same time, they feel very lonely and isolated, and hope that someone will care and understand them. They constantly search for friends, and once they find them, they will push their hearts and minds without reservation. 3.Brave and cowardly In some cases, junior high school students seem to be able to show a strong brave spirit, but this time the brave with reckless and impulsive elements, with the characteristics of the newborn calf is not afraid of the tiger, do things rarely bound by the rules and regulations. But on the other hand, they are often shy in public, not frank and calm. 4. Pride and low self-esteem Since junior high school students are not yet able to evaluate and recognize their own intellectual potential and character traits exactly, it is difficult for them to make a comprehensive and appropriate evaluation of themselves, but to draw light conclusions about themselves by virtue of their momentary feelings. This leads to their improper grasp of their own self-confidence level. A few or even a chance success can make them think they are a very good talent and complacent, and a few chance losses can make them think they are incompetent and extremely inferior. These two emotions often appear alternately in the same junior high school students. 5, denial of childhood and attachment to childhood As the body develops and matures, the consciousness of adults becomes more and more obvious, believing that all their behavior should be different from that of children, trying to deny their own childhood from every aspect. However, while denying their childhood, they still have some longing for it in their hearts. All in all, junior high school students have a sense of adulthood and childishness together.
