Adolescents
Brain development in adolescents
Adolescence is the period of psychological and social transition from childhood to adulthood. This period of life is characterized by psychological changes when it comes to self-consciousness, identity and mood. Brain imaging studies conducted recently show that the human brain continues to develop throughout their adolescent years. Although there are some differences between the male and female teenagers when it comes to the course of the neural development, significant brain restructuring takes place in terms of the course of their neural development in both sexes.
The regions of the brain where development is protracted include prefrontal cortex and the temporal parietal cortex. The frontal cortex area is responsible for cognitive abilities like making plans, remembering details, inhibiting inappropriate behaviors and so on. It also plays an important role in understanding others and self-awareness. Since this pre-frontal cortex of the adolescent brains mature, older adolescents aged 18-19 are in a position of making conscious decisions and even control their impulses. This pre-frontal cortex does not reach full maturity until one is 25 years of age (Lorain, 2009). The development of these regions is what most likely contributes to the behaviors that are typically associated with an individual who is in their teenage years for instance susceptibility to peer pressure, increased risk taking and reduced self-control. The corpus callosum also changes during adolescent and this is the area that influences the learning of language as well as thinking. Lastly changes in the cerebellum also occur during ones...
However, unlike the pre-frontal cortex and corpus callosum it changes well into the adolescent years. This part of the brain is what helps in balance and coordination also it also helps an adolescent to process mental tasks and guide them through their social lives which are quite complex at this stage ( Burnett, Sebastian, & and Blakemore, 2009).
Some of the typical adolescent behaviors that are reinforced by brain development are preference of interaction with ones peers, preference of active to passive learning and the engagement in strong and intensive interests that are often short lived (Lorain, 2009).
2. Identity formation
Identity formation is the process through which one develops their own distinct personality. The formation of ones identity does not begin nor end in adolescence however; it takes a great importance during this period. There are various reasons why the adolescent period is termed as key when it comes to formation of identity these include; self-concept that includes both actual self and possible self. In early adolescence cognitive developments lead to greater awareness of one self, others and their judgments and thoughts, being able to think about abstract, future possibilities and being able to consider multiple personalities. This leads to adolescents experiencing a shift from simple, global and concrete descriptions that are typical of young children. At the childhood stages, people define themselves with their physical traits while as adolescents they define themselves on the basis of their thoughts, opinions and values.
The second reason is gender, culture, ethnicity and…

Adolescence Describe two ways that brain development typically contributes to changes in thinking and behavior as individuals progress through adolescence (448-451). Provide two specific examples of how most adolescents think and reason (pp. 485-493). Because of the "Dramatic transformations" that occur during adolescence in the prefrontal cortex and the limbic brain regions, feelings of "fear and anger" emerge in the adolescent (p. 448). These fears and angry responses are due to the
Adolescent Substance Use Screening Instruments: 10-Year Critical Review of the Research Literature Over ten million teenagers in the United States admit in a national survey that they drink alcohol, although it is illegal under the age of 21 in all states. In some studies, nearly one-quarter of school-age children both smoked cigarettes and drank alcohol. Over four thousand adolescents every day try marijuana for the first time. The dangers of use,
This includes factors such as peer pressure, family life and the norms and values of society that often are determining factors in the development of the individual., The above discussion leads to a number of central conclusions. The first is that there are many interrelated variables that can lead to certain negative patterns of behavior. What is of particular concern is that negative factors such as alcohol and other forms
All too often, these adolescents end up taking their own lives when their depression gets too painful for them and they have not received the help that they need. Even the medications that are designed to help them get through the depression can sometimes make things worse, as various medications for depression and anxiety carry a risk of suicide when people are just starting or just getting off of
This graph shows that some adolescents start to smoke as early as 11 years, but "in general the ages 13 through 18" are the years when most adolescents start. The facts according to "The Teenager's Guide to the Real World" are that "No one starts smoking after age 20." So if a person can make it to the age of 20 without lighting up that first cigarette, he or she
Unfortunately, for those individuals who did not use direct coping strategies but instead used the kind of coping that distances one's thoughts, emotions, and physical presence from the stressor (e.g., denial and wishful thinking) or disengages completely (e.g., escape and emotional numbing) to cope with discrimination stress tended to have lower self-esteem. Consequences/Effects of Low Self-Esteem A number of studies have shown that low self-esteem is predictive of negative outcomes. Parker
