IntroductionAdolescence is a transition that has no fixed time limits. However, the changes occurring at this time are so significant that it is useful to talk about adolescence as a distinct period of the human life cycle. This period ranges from biological changes to changes in behavior and social status, thus making it difficult to specify its exact limits (Damon, 2008). Adolescence begins with puberty, that is, with a series of physiological changes that lead to the full development of the sexual organs and reproductive and sexual capacity. The time interval that passes begins from 11 to 12 years and extends from 18 to 20. However, we cannot associate a 13 with an 18 year. We are talking about early adolescence between the ages of 11 and 14, which coincides with puberty, and after a second period of youth, or late adolescence between the ages of 15-20. Its extension to adulthood depends on social, cultural, environmental and personal adaptation. Thesis Statement The purpose of this article is to explore the impact of environmental influence on the developmental process of adolescent Social Discussion; sciences have changed the way of thinking of young people, who have different points of view on different things. The process of adolescent development ritually influenced children. As children develop, physical changes will be obvious to the casual observer. What is less obvious are the many important physiological and neurological changes that occur that will facilitate other areas of development. During infancy and early childhood, children develop an incredible number of synapses, or branches that extend between neurons. Shortly after this amazing growth cycle, many of these synapses disappear. These remain the most frequently used ones. Does this pro...... half of the article ...... technically present the three general perspectives that guide today's researchers and practitioners of developmental psychology, David Bjorklund and Carlos Hern? CHILD AND ADOLESCENT DEVELOPMENT: AN INTEGRATED APPROACH shows how major perspectives on human development should be integrated? Rather than presented as contrasting and sometimes contradictory ways of looking at development? To meaningfully understand infants, children and adolescents and how they develop. Maholmes, V., Lomonaco, G.C., (2010), “Applied research in child and adolescent development: a practical guide”, Taylor & Francis. This book is a much needed guide to doing applied research in human development. He provides excellent personal examples of how basic researchers have expanded into applied areas and great advice on how to conduct the best applied research.
