2 Factor analysis of personality development defects of college students

2. 1 physiological factors The type of advanced nervous system determines the type of temperament, and people with various temperament types will have their specific tendencies in personality. For example, people with depression are more likely to form personality defects such as depression, inferiority, loneliness, stubbornness and paranoia; People with choleric temperament are more likely to form personality defects such as impulsiveness, mania and aggression [9].

College students are in the late stage of puberty. Due to the lack of scientific and systematic health education, the physiological changes brought by adolescence often cause them to be restless, which will lead to personality development defects such as fear, depression, anxiety and impulsiveness. Some college students will also self-reprimand, self-hate, self-despise and feel depressed or scared all day because they don't understand some normal physiological development laws of people.

2.2 Psychological factors From the psychological point of view of college students, some defects in their understanding, ability, will, emotion, personality and temperament will all lead to the formation of personality development defects. For example, when college students are worried about their future or lack of ideal pursuit, or have insufficient understanding of the harmfulness of personality development defects, they will be prompted to form some personality development defects; When college students lack self-care ability, interpersonal skills, poor academic performance, or can't face up to and accept themselves because of personal appearance, physical defects, family poverty and other reasons, they will also form some personality development defects. Once college students form a wrong outlook on life and the world, or they are pessimistic or hate the world, they will give up their personal moral cultivation and are more likely to form personality development defects. 2.3 Social factors The social environment in which college students live is an important factor leading to their personality development defects. From the perspective of family environment, parents' disharmony, lack of parental care, high expectations of parents, unscientific education methods of parents, and parents' own bad personality tendencies are all social factors that promote children to form personality development defects; From the school environment, teachers' high expectations, students' heavy learning burden, class spirit, unhealthy school spirit, disharmony in interpersonal relationship and teachers' personality defects are all important factors that promote college students to form personality defects. Judging from the social environment, all kinds of unreasonable competition, corruption and the bad influence of various media in society will promote students to form personality development defects.
