Self-awareness is the awareness of one's physical and mental activities, that is, the understanding of oneself, which specifically includes understanding one's physical condition (such as height, weight, posture, etc.). ), psychological characteristics (such as interest, ability, temperament, personality, etc. ) and their relationship with others (such as their relationship with the people around them, their position and role in the group, etc. ).

The development of college students' self-awareness has gone through several stages: infancy, infancy, childhood, adolescence, rebellion, youth and middle age.

The structure of college students' self-consciousness is divided into three levels. It consists of three subsystems: self-cognition, self-experience and self-regulation (or self-control). Self-knowledge of extended materials is a person's understanding and evaluation of himself, including his own psychological tendency, personality psychological characteristics and psychological process. It is precisely because people have self-awareness that they can control and adjust their thoughts and behaviors and form a complete personality.

College students' self-awareness plays a very important role in individual development. Self-awareness is the product of individual's long-term socialization. This is not only because it is produced in social practice, but also because its main content is a reflection of individual social attributes. The understanding of self-essence is not the understanding of individual physiological characteristics, but the understanding of individual social characteristics and social roles, which is an important symbol of self-consciousness maturity.
