Document Summary
Chapter 15 adolescence: g. stanley hall believed that this tension between biological maturity and social dependence creates a period of storm and stress. Adolescence the transition period from childhood to adulthood, extending from puberty to independence. Physical development: adolescence begins with puberty, the time when we mature sexually. Puberty the period of sexual maturation, during which a person becomes capable of reproducing. Primary sex characteristics the body structures that make sexual reproduction possible (ovaries, testes, and external genitalia) Such variations on timing may have psychological consequences. Boys who are stronger and more athletic in their early teen years tend to be more popular, self-assured: an adolescent"s brain is also a work in progress. Then during adolescence comes a selective pruning of unused neurons and connections: frontal lobes also continue to develop. The growth of myelin, the fatty tissue that forms around axons and speeds neurotransmission, enables better communication with other brain regions.
