hereditary factor
A person's whole (including both physical and mental aspects) is closely related to heredity, especially a person's body shape, temperament, characteristics of nervous structure, ability and some components of personality are obviously affected by genetic factors. Biological research tells us that heredity and variation are important characteristics of organisms. On the one hand, creatures are constantly changing under the influence of the external environment, showing characteristics different from their parents; On the other hand, organisms can maintain certain stability and continuity during their reproduction. It is now known that the substance that keeps the organism stable and continuous is the chromosome in the germ cell. Studies have shown that some mental diseases are related to heredity, such as schizophrenia, manic depression, personality disorder, certain types of mental retardation and paranoid mental disorder, and often have obvious genetic tendency.
Early education and family environment
Family is the cell of society, not only the economic unit of society, but also the concentration point of various moral concepts in society. Lin Gelun, an American educational psychologist, said: "Children's initial education is provided by their parents rather than schools, and these activities begin in infancy." Therefore, early education and family environment are also one of the important factors affecting mental health.
The research on individual's early development shows that those babies who grow up in monotonous and harsh environment are hindered in their psychological development and will inhibit their potential development. The relationship between children and parents and parents' attitude towards children are also important factors affecting individual mental health. This early mother-infant relationship, as well as the relationship between children and parents later, has great influence on individual interpersonal relationship and social adaptation in the future. If children can establish and maintain a good relationship with their parents at an early stage, it will play a positive role in promoting their social adaptation and interpersonal relationships in the future. On the contrary, if the child can't establish this intimate relationship with his parents in the early stage, or he is separated from his parents in the early stage, it will have a negative impact on his future growth.
The influence of family environment on individuals is mainly manifested in: (1) the influence of natural family structure on individuals. Research shows that an incomplete family has a very harmful effect on children's mental health. Children who lack maternal love will have no sense of psychological stability and have emotional and personality disorders. Such children tend to be withdrawn and indifferent.
