Examples of life stages

The human being develops from its conception as follows:

  1. Prenatal stage

This is the time that includes the moment of conception. In this period it is prior to birth, but the recognition of sounds and touch begins. At the scientific level , it is estimated that during this time the human brain begins to associate the appropriate response stimuli.

It is considered the first stage of life , since it goes from the moment of fertilization and ends nine months (usually) later, at the time of delivery. During this time, this stage goes through three phases:

  • Zygote phase: Also called germ phase , since this is the moment in which the ovum is fertilized by the sperm. In this period it is called a zygote.
  • Embryonic phase: From this moment on, it is not called a zygote, but an embryo. It is a period susceptible to strong odors, infections and radiation. It is here when the embryo begins to specialize to form what will be the tissues of the fetus and ends at week ten of pregnancy.
  • Fetal phase: At this point the structures that had been formed in the embryonic phase, develop in the fetal phase and grow until obtaining the human form , to continue developing until the moment of delivery.
  1. Childhood stage

It is the first stage that lives outside the mother’s body. At this time, the baby begins to use indiscriminate emotional responses (crying), it is a time of discovery, exploration and language learning, in which later he begins to control. This stage ends at four years of age.

  1. Early childhood stage

It is a stage that begins at four and ends at six years of age. It is called the preschool stage , since during that time, the child prepares to start learning at school. They are taught the fundamental values ​​and principles of society.

  1. Middle childhood stage

It begins at six years of age and ends at eleven. During this time an attempt is made to explain to the child that there are harmful influences in society, from which they must be protected.

The learning of values taught during early childhood also develops and there is progress in the ability to learn operations and phrases of complex structures.

  1. Adolescence stage

It is said that it is the stage that suffers the most, due to the different hormonal changes that occur, since it is the entrance to puberty, which comes with sexual maturation , the appearance of body hair, deepening of the voice in males and the beginning of female menstruation.

This period begins at twelve and ends at seventeen. It is where the ability to think and the search for his own identity is consolidated, in which he discovers the world that surrounds him, appreciates the values ​​to take on the way to adulthood and his sentimental life.

It begins at approximately 18 and ends at 35 years of age. It is at this time where friendships are consolidated, the degree of independence begins, so as not to depend on parents and at this time is overcoming the turbulence presented in adolescence .

At this stage, social and work life are the priority of the individual, since they are more aware and determined of who they are.

  1. Stage of maturity

It begins at 36 and ends at 50 years of age. During this time, there will be a labor consolidation , where the interest comes from the specialization of the area in which it has been working, to obtain greater income and life benefits.

  1. Stage of mature adulthood
