The three principles for judging mental normality and abnormality are the internal coordination of psychological activities, the unity of subjective world and objective world, and the relative stability of personality.
Three principles for judging mental normality and abnormality;
1. Internal coordination principle of psychological activities. The harmony of knowledge, emotion, will and action is the overall expression of human spiritual activities. A person's psychological process is consistent in the consistency of inner experience and environment. If he laughs when he laughs, he cries when he cries. His son was beaming at the wedding, and his deceased relatives cried at the funeral. This is the harmony between emotion and environment. Sick is abnormal and sick, that is, you should cry and not laugh.
2. The principle of the unity of the subjective world and the objective world. Any normal psychological activity and behavior, regardless of its form and content, should be consistent with the objective environment, that is, identification. As long as people's psychology or behavior loses their recognition of the outside world, it is difficult to be understood.
3. The principle of relative stability of personality. Everyone will form their own unique personality and psychological characteristics in the long-term life. This personality trait is relatively stable after it is formed, and it is generally not easy to change without major external changes.
Causes of psychological abnormality:
Heredity. Psychological disorders are generally caused by heredity. If both parents are introverted, then the possibility of children inheriting their parents' psychological barriers is above 80%, so family genetic history is the most obvious reason for psychological barriers.
2. Living environment. Many people live in a depressed environment, or some children have strict family education, and even parents will use violence, so if they grow up in this living environment, it is likely to lead to psychological obstacles.
3. Mental stress. It may be a person's personality, personality defects, mainly because the patient is introverted, sensitive, suspicious or strong, perfectionist, picky or extreme, and easy to walk into a dead end. If you have personality problems, you are prone to various mental and psychological diseases.
