How do people grow physically, intellectually, socially, and morally?.
People go through stages of life from birth to death that shape their body, their personalities, thoughts, interactions with people, and also develop a personal code of ethics. Through every stage, there is an outcome, as described from many famous developmental psychologists. The outcome can either be negative or positive, in most cases. .
People grow physically starting from birth. During Infancy, most of the brain cells a person will ever have are present at birth. However. the neural connections that enable walking, talking, and memory are only beginning to form through the span of childhood. This neural immaturity may explain why we have no memories of events before 3 years of age, also because our hippocampus isn't fully developed. While lasting memories may not be formed before then, infants are capable of learning simple responses. After puberty, a process of pruning shuts down neural connections and strengthens others to form a more complex process thinking. During adolescence, puberty begins. Puberty is a two year period of rapid development that begins in girls at about age 11 and in boys at about age 13. During the growth spurt, sexual maturation occurs, as the primary sex characteristics (reproductive organs) and secondary sex characteristics (non reproductive traits) develop dramatically. During adulthood to late adulthood, muscular strength, reaction time, sensory keenness, and cardiac output all peak by the mid twenties and begin to decline thereafter. For woman, menopause is the foremost biological change related to aging. Men experience a gradual decline in sperm count, testosterone level, and speed of erection and ejaculation as they get older. Decline in the functioning of the body's disease fighting immune system makes the elderly more susceptible to life-threatening aliments such as cancer and pneumonia.
