Stages of Adolescence

Adolescence, these years from puberty to adulthood, may be roughly divided into three stages: early adolescence, generally ages eleven to fourteen; middle adolescence, ages fifteen to seventeen; and late adolescence, ages eighteen to twenty-one.

Physical Development

Puberty is defined as the biological changes of adolescence. By mid-adolescence, if not sooner, most youngsters’ physiological growth is complete; they are at or close to their adult height and weight, and are now physically capable of having babies.

Intellectual Development

By late adolescence, many youngsters have come to appreciate subtleties of situations and ideas, and to project into the future. Their capacity to solve complex problems and to sense what others are thinking has sharpened considerably. But because they are still relatively inexperienced in life, even older teens apply these newfound skills erratically and therefore may act without thinking.

Emotional Development

they distance themselves from Mom and Dad. The march toward autonomy can take myriad forms: less overt affection, more time spent with friends, contentious behavior, pushing the limits—the list goes on and on. Yet adolescents frequently feel conflicted about leaving the safety and security of home.

Social Development

Not all teenagers enter and exit adolescence at the same age or display these same behaviors. What’s more, throughout much of adolescence, a youngster can be farther along in some areas of development than in others. For example, a fifteen-year-old girl may physically resemble a young adult but she may still act very much like a child since it isn’t until late adolescence that intellectual, emotional and social development begin to catch up with physical development. But beyond learning to anticipate the shifting currents of adolescent emotion, mothers and fathers may be struggling with some conflicting emotions of their own. The pride you feel as you watch your youngster become independent can be countered by a sense of displacement. As much as you may accept intellectually that withdrawing from one’s parents is an integral part of growing up, it hurts when the child who used to beg to join you on errands now rarely consents to being seen in public with you, and then only if the destination is a minimum of one area code away.
