Stages of Human Development

People are born in this world and die. In the course of life, a person changes or, in other words, develops.

Let us consider the main stages of individual mental development of man.

The development of the human body begins from the moment of fertilization, when the father and mother cells merge. As part of the development of a new human body occurs in the womb of the mother, the prenatal and postnatal periods are singled out.

In the intrauterine (prenatal) period, two phases can be identified: embryonic (up to 3 months) and fetal (from 3 to 9 months). Certainly, it can be argued that mental development occurs during this period. Basically, it depends on the lifestyle, nutrition, as well as the physical and mental state of the mother, taking into account all factors affecting him.

Stages of postnatal development of the human psyche

1. In the first seconds of birth and the first breath of a child, a relatively independent life begins for him. There is an adaptation of the body to the environment. The child's knowledge of the world is layered on the genetic basis and implemented genetic program, thanks to which complex transformations take place in the body and psyche. Psychology (both age and general) is known for a variety of completely rational approaches to the systematization of the stages and phases of human development up to the adult period of life.
2. Up to 20-25 years of age, the mental development of the personality is directly related to physical growth. Further development does not stop, just physical changes in the body are slower and not as noticeable as before.
3. The period from 20-25 to 55-60 can be considered mature (in turn, this stage can also be divided into phases).
4. After 60 years, the human body begins to develop involuntarily (that is, gradually grow old). Such biophysical changes, of course, are decisive for changes in the psyche.

conclusions

In general, you can see the following. In the process of human development, the nature of his needs is changing, both vital and socio-cultural. The infant is dominated by simple vital needs associated with basic biological functions (nutrition, breathing, sleep, etc.). More complex physiological needs associated with the assimilation of various nutrients, with movement in space, growth and development, as well as arbitrary and independent performance of regulated physiological functions are formed gradually. Already in the first year of life, the child begins to form cognitive needs and need for communication. Further changes in social and communicative development span a long period, including the mature life of the individual.

The highest forms of personal development are creative manifestations and achievements, the accumulation and comprehension of new knowledge, the creation and understanding of the involvement in cultural values , the pursuit of certain spiritual and moral orientations.
