The human life cycle is divided into seven distinct stages, from infancy to old age. According to the Bodynamic System, a child's development progresses through a series of overlapping age phases from the second trimester in the womb to the age of 12. Adolescence is also considered a significant period of personal development, and later in life, the personality is remodeled through a series of phases of adult development, which interact with the character structures established during childhood and adolescence. The Structure of Need identifies three positions that can result in distortions of self and relationships: collapsed or early position (Despair), rigid or late one (Distrustful), and healthy or balanced position (Self-Satisfying). A baby's survival depends on meeting his basic needs.
If these needs are not met, he will fall into deep despair. On the other hand, if his needs are met by a good enough mother, he will likely experience the feeling of being satisfied with himself. This is the beginning of self-regulation. In adults, interruptions at this stage can manifest as a desperate or suspicious attitude about being able to meet their needs and not being aware of what their needs are or how to feel satisfaction.
As the child grows, his curiosity and life force lead him to explore the world through an explosion of psychomotor skills. This is also the time to acquire and master high-level skills. Interruptions at this stage can lead to fear of competing or excelling in a group, or the need to be the star of any group despite the consequences for oneself or the group. The child finds his place in their culture by learning to be a member of the group and the community.
Physically, a healthy person has a straight back, an upright posture and flexible and fluid movements. He likes to use and develop his physical and mental abilities and will practice repeatedly to improve his skills. The first stage of child development is the newborn stage. During this period, the child adapts to the new environment, begins to experience stimuli and adapts to the demands of the environment. When he manages to maintain himself in life, he begins to grow rapidly and move to a childhood stage.
Here, the main problem for the newborn is getting the right diet that should allow his successful development of organs for their normal execution of functions. The first signs of autonomy are seen during the toddler stage, when every day he becomes more independent in his environment and begins to show challenging behavior. He then transitions to preschool age where his intelligence is developing rapidly and autonomy is growing. During this period, he extends his circle of people with whom he contacts. Now he can leave home from time to time and go to another environment, such as kindergarten.
But as society develops, higher expectations are set for each member. The individual must acquire greater knowledge, life experience, professional skills, emotional maturity before they can meet all requirements that society expects from them. After babies begin to crawl, stand and walk, their increased physical mobility leads to greater cognitive development. Near the end of the sensorimotor stage (18-24 months), babies reach another important milestone - early language development. Developmental psychology has seven stages including childhood, childhood, lover, welding, justice, old age, and finally dementia and death. During toddler years children continue to sleep a lot, eat well, and have loving relationships with parents and caregivers.
Interruptions at this stage can lead to acting from a selfless position and having difficulties in planning. Piaget's theory of 1936 broke new ground because it discovered that children's brains work in very different ways than adults. If it develops properly, the child should switch to mixed foods during the first year of life, slowly stopping lactation. Child development theories focus on explaining how children change and grow throughout childhood. In adults, interruptions at this stage can lead to a division between amorous and sexual feelings, and a romantic or seductive way of being in a relationship. Although Piaget believed in intellectual growth for life, he insisted that the formal operational stage is the final stage of cognitive development. During this stage cells begin to form a body system; neural tube is formed; head; eyes; nose; etc.
