Yes, ages 10 to 19 is adolescence, but they are different stages of adolescence. Just because a 10 year old and a 19 year old are both adolescents, do you really think that they are one and the same?
Early Adolescence (10-13 Years Old)
This is usually when puberty begins, although it can start earlier in some cases. During this period,
CHILDREN often have growth spurts and typically begin to experience sexual interest. Most girls begin to develop breasts during this period, and both girls and boys begin to grow body hair on their legs, armpits, and genitals. It is also during this time that most girls get their first menstrual cycle. In terms of behavior,
KIDS in this stage typically struggle with abstract thought (concepts) and may have a worldview that lacks complexity. This is also when they begin to develop their deeper sense of morality, or the difference between right and wrong, but still tend to think of things in fairly black-and-white terms.
Late Adolescence (18-21 Years Old)
By the time they reach late adolescence and early
ADULTHOOD most physical changes are complete. By this age, most people have reached their adult height and completed puberty. Instead, most of the changes that take place at this stage are cognitive (involving thinking and reasoning) and behavioral. The brain actually does not finish developing until a person is in their mid-20s. However, by the time most people are 18 through 21 years of age, they have rational thinking skills and the ability to overcome impulse with logic.
There are three major stages of adolescent development, including early adolescence. Each stage comes with different behavioral, psychological, and physical developments.
