Development And Change Of Humans Throughout Life

Development is a multidirectional and complicated process. There are various disciplines lying underneath the investigations about this process: Biopsychology, cognitive psychology, developmental psychology, social psychology, and clinical psychology are some of them. The roots of behavior and health goes back to the baby’s mother’s womb. Epigenetic mechanisms move into the process. Genetic mechanisms, environmental conditions, and interaction of the two play a key role during this development and change. Early life experiences, the adversity, stress, traumatic events that have been lived, family and school and other social environments, family, and friend relationships, eating and sleeping habits affect a person’s development and change. When something happens, the effect of it can be seen so many years later. So, this means; if an illness has started in a body, in fact the trace of it has been started years before. However, one can change these effects by changing the lifestyle. When a sperm enters the vagina, sperm cells go on to the fallopian tubes and meet the egg and get fertilized. The development starts here in the womb. Psychologists group the developmental periods as, beginning from the birth till 2 years, 2 to 5 years old, 5 to 12 years old, 12 to 18 years old, adulthood, middle age, and old age. The biological, cognitive, social, and emotional changes differ according to these periods and according to the sex as well. All these developments and changes affect each other. Epigenetic changes that occurred because of the environmental conditions do not change the DNA sequence however they cause the genes to be active or passive. They influence gene expression and cause chemical changes. This knowledge gives hope that, if a proper life has been lived, problematic genes may not be activated. There is always the probability to change towards healing or towards a skillful life. The last stage of the development is inevitably death. It is closely related to a person's and the society’s culture and religious beliefs; so, the acceptance of death and approaches to death differ from culture to culture.
