Age difference in dating teenagers
A thorough understanding of adolescence in society depends on information from various perspectives, including psychology, biology, history, sociology, education, and anthropology.
During their peak height velocity (the time of most rapid growth), adolescents grow at a growth rate nearly identical to that of a toddler—about 4 inches (10.3 cm) a year for males and 3.5 inches (9 cm) for females.Some boys may develop gynecomastia due to an imbalance of sex hormones, tissue responsiveness or obesity.As with most human biological processes, this specific order may vary among some individuals.Consequently, girls that reach sexual maturation early are more likely than their peers to develop eating disorders (such as anorexia nervosa).Nearly half of all American high school girls' diets are to lose weight.Puberty is a period of several years in which rapid physical growth and psychological changes occur, culminating in sexual maturity.
The average age of onset of puberty is at 11 for girls and 12 for boys.
The testes primarily release testosterone, and the ovaries predominantly dispense estrogen.
The production of these hormones increases gradually until sexual maturation is met.
The accelerated growth in different body parts happens at different times, but for all adolescents it has a fairly regular sequence.
The first places to grow are the extremities—the head, hands and feet—followed by the arms and legs, then the torso and shoulders.
In studying adolescent development, adolescence can be defined biologically, as the physical transition marked by the onset of puberty and the termination of physical growth; cognitively, as changes in the ability to think abstractly and multi-dimensionally; or socially, as a period of preparation for adult roles.
