Therefore, it is important to enhance proper monitoring which entails accountability, mentorship, and guidance. At this stage, most people fail to depict the development process in adolescence thus, when conflicts emerge misunderstanding and miscommunication occurs. To ensure that all people navigate the transitions well, it is vital for adults to understand what is happening to the teen socially, physically, and cognitively. In facts, if all people are equipped with knowledge of what occurs in adolescence stage then, there will be few issues to deal with and conflicts to solve. In reality, this stage involves a lot of transformation in terms of body features, brain, and mind among others. Girls develop differently from boys but, in all changes there are similarities in the way the changes appear. In this context, the purpose of this paper is to discuss development during adolescence, and in doing this, I will highlight various developments that occur. In doing this, the essay will be divided in different sections that outline various developments that occur in this stage, and how these changes affect teens. After reading this essay, one should be able to recognize the development in adolescences and various issues that adolescents encounter during this stage. 1. Physical development Studies outline that, adolescent years involve a lot of physical changes that include development of muscles, bones, and organs (Thomburg, 2007). During this stage, there are a lot of physical developments, which occur at a high rate as compared with infancy. Physical developments include rapid gains in weight and height, development of sex characteristics, and brain development. Rapid gains in weight and height occur during one year growth spurt where boys and girls gain an average height of 3.5 Inches and 4.1 inches respectively. This change occurs differently whereby girls tend to develop two years earlier than boys. In facts, weight gain is attributed by the increase of muscles in boys, while body fats are responsible for weight gain in girls. During puberty, change in hormones plays a vital role in enhancing development of secondary sex characteristics. These include menstrual period for girls, growth of hair in private areas, penis growth for boys, an increase in production of oil, underarm hair growth, voice changes and growth of facial hair for boys, and the increase of sweat gland activity. Recent studies indicate that, adolescents’ brain is not fully developed until in the late adolescence (Kroger, 2007). Specifically, it is said that, the connections of neurons affecting physical, mental, and emotional abilities are incomplete. Therefore, this explains why some teens are incoherent in controlling their impulses, judgment, and emotions. How these changes affect adolescents The above changes affect teens in various ways. First, teens tend to sleep longer to allow their bodies to conduct energy required for such a rapid growth. On average, require about nine and half hours of sleep at night. Secondly, teens may be more awkward because body parts do not grow at the same rate. This can lead to depression as adolescents try to cope with changes that occur in their bodies. Thirdly, teenage girls may become exceedingly sensitive with their body image, and this may arise because of rapid weight gain linked with puberty. In this case, most teenage girls become so worried about their weight that, they develop eating disorders such as dieting to lose weight.
