Hormonal changes in puberty: growth hormone and thryoxine increase around age 8-9, estrogens more in girls, adrenal estrogens, androgens more in boys, testosterone. Sexual maturation: primary sexual characteristics (maturation of the reproductive organs) Boys: spermarche: secondary sexual characteristics (other parts of the body that signal sexual maturity) There is an overlay b/w biology and society how hormonal growth is seen. Go through different experiences; one that we experience at 12 years old will be different than when we"re 17. Individual differences in timing of puberty: heredity, nutrition, exercise. Body fat, leptin in girls: geographical location, ses, family experiences, secular trend, when puberty happens it is not a universal experience: depends on who you are, where you are, family history. Berk"s perspective boys can gain more support if they talked to people more (about the changes they"re undergoing) Emotional responses to puberty: more negative life events, stronger responses.
