IntroductionAdolescence is a transition that has no fixed time limit. However, the changes occurring at this time are so significant that it is useful to talk about adolescence as a separate period in the human life cycle. This period extends from biological changes to changes in behavior and social status, making it difficult to precisely specify its boundaries (Damon, 2008). Adolescence begins with puberty, that is, a series of physiological changes that lead to the full development of the sexual organs and the ability to reproduce and have sexual relations. The time interval that passes begins between 11 and 12 years and extends to 18 and 20 years. However, you cannot associate a 13 with an 18 year old. Let's talk about the beginning of adolescence between 11 and 14 years old, which coincides with puberty, and after a second period of youth, or end of adolescence, between 15 and 20 years old. Its extension into adulthood depends on social, cultural, environmental and personal adaptation.Thesis StatementThe aim of this article is to explore the impact of environmental influence on the adolescent development processDiscussionSocial; Science has changed the way young people think, and they have different views on different things. The process of adolescent development ritually influenced children. As children develop, physical changes will be apparent to the casual observer. What is less obvious are the many important physiological and neurological changes that will facilitate other areas of development. During infancy and toddlerhood, children develop an incredible number of synapses, or branches that extend between neurons. Shortly after this fantastic growth cycle, many of these synapses disappear. Those that are used most frequently remain.

CHILD AND ADOLESCENT DEVELOPMENT: AN INTEGRATED APPROACH shows how the major perspectives on human development should be integrated? Rather than presenting contrasting and sometimes contradictory ways of considering development? To meaningfully understand infants, children and adolescents and their development.Maholmes, V., Lomonaco, GC, (2010), “Applied Research in Child and Adolescent Development: a Practical Guide”, Taylor & Francis. The book is an indispensable guide to doing applied research on human development. He provides excellent personal examples of how basic researchers have developed into applied fields and excellent advice on how to conduct the best applied research..
