It's adolescence it meansĀ the period following the onset of puberty during which a young person develops from a child into an adult.
Human growth and development is characterized by several distinct and unique stages beginning with conception and ending at death. Like all stages of human development, adolescence is an important stage. In this lesson, we will focus on the biological, cognitive, and socio-emotional aspects of adolescence, which make it unique and distinguishable from the other stages of human development. For most humans, adolescence begins around age 10 to 12 and concludes somewhere between 18 to 21 years of age. It is important to remember that age alone does not signify the beginning and end of adolescence, but rather achieving key developmental milestones indicates when a particular stage of development has begun or concluded.
