The document discusses physical, emotional, and cognitive development during adolescence. Puberty is triggered by hormones like growth hormone, testosterone, and estrogen. This causes physical changes like growth spurts and development of secondary sex characteristics. Adolescents' brains experience changes as the prefrontal cortex matures and the limbic system remains influential, impacting impulse control and decision making. Emotionally, teens develop their identity, gender roles, ethnicity, and form relationships by joining peer groups or cliques which can influence their identity development. Their moral reasoning also becomes more sophisticated as they progress through Kohlberg's stages of moral development.
