Researcher James Marcia developed the current method for testing an individual's progress along these stages. Early maturing boys are usually taller and stronger than their friends.

Changes in the levels of the neurotransmitters dopamine and serotonin in the limbic system make adolescents more emotional and more responsive to rewards and stress.
During puberty, bones become harder and more brittle. In addressing this question, it is important to distinguish whether adolescents are more likely to engage in risky behaviors prevalencewhether they make risk-related decisions similarly or differently than adults cognitive processing perspectiveor whether they use the same processes but value different things and thus arrive at different conclusions.
The less turbulent aspects of adolescence, such as peer relations and cultural influence, were left largely ignored until the s. Between the ages of 10 and 25, the brain undergoes changes that have important implications for behavior see Cognitive development below.
For example, in the United States of America, bone density increases significantly more among black than white adolescents, which might account for decreased likelihood of black women developing osteoporosis and having fewer bone fractures there. Changes in the brain The human brain is not fully developed by the time a person reaches puberty.

There are not notable differences by racial or ethnic group: Children younger than age nine often cannot comprehend sarcasm at all. The second stage, identity confusion, tends to occur a few years later. It often involves monitoring one's own cognitive activity during the thinking process.
Development in the limbic system plays an important role in determining rewards and punishments and processing emotional experience and social information. The weight gained during adolescence constitutes nearly half of one's adult body weight.Nearly two-thirds of American adults (65%) use social networking sites, up from 7% when Pew Research Center began tracking social media usage in Adolescence (from Latin adolescere, meaning 'to grow up') is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood (age of majority).
Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier and end later.Download
