1. The cognitive function is mature, and the thinking shows more logical and rational colors.

Cognition refers to an individual's views, thoughts or opinions on the surrounding things, which are manifested in a series of processes such as perception, memory, thinking and imagination, including psychological contents such as explanation, evaluation and expectation of stimuli. Mature cognitive function can enable individuals to correctly understand themselves, properly evaluate others, objectively examine the surrounding environment and actively adapt to social life.

2. Self-awareness is mature and willpower is enhanced.

Personal self-awareness gradually matures in the university stage, mainly in the following aspects. First, the sense of independence is enhanced. College students' physical development is basically mature, the degree of socialization is greatly improved, and they have strong adult consciousness and independent consciousness psychologically. They want to get rid of their dependence on adults, show their views and abilities to the people around them, and don't like too much interference from others. Second, self-cognition and evaluation are more comprehensive and accurate.

3. Colorful emotions and strong communication needs.

The university stage in its prime is often the period with the richest emotional experience in life. College students' mood fluctuates greatly, and there are obvious emotional transformations, such as enthusiasm, depression, pessimism, calmness and anxiety. They are happy for the success of study, life and love, sad and distressed for the failure of exams and setbacks in life, desperate for truth and friendship, and indignant for ugliness and darkness. In them, self-esteem and inferiority can coexist, atresia and openness can coexist, and strong roughness and gentleness can coexist.
