What is the term used for the period of development from ages 12 to 18?

The term used for the period of development from ages 12 to 18 is adolescence. During adolescence, individuals undergo significant physical, emotional, and social changes as they transition from childhood to adulthood. This developmental stage is characterized by a growth spurt, the onset of puberty, and the exploration of identity and independence. Adolescents often experience heightened emotional fluctuations and peer influence plays a crucial role in their social development. This period is also marked by important cognitive developments, including the ability to think more abstractly and critically.

Childhood refers to the earlier stages of development, from birth up until around the age of 11, where the focus is primarily on basic physical and cognitive skills. Adulthood follows adolescence and typically begins in the late teens or early twenties, encompassing a time when individuals are expected to assume more responsibilities and make independent life choices. Infancy refers to the first year of life, a time predominantly focused on basic needs, attachment, and sensory development.
