Document Summary

Discuss changing conceptions of adolescence over the twentieth century, and identify the three phases of adolescence recognized in modern industrialized nations. Adolescence is the transition between childhood and adulthood. Early theorists viewed adolescence as either a biologically determined period of storm and stress or entirely influenced by the social and cultural environment. Contemporary research shows that adolescence is a joint product of biological, psychological, and social factors. In cultures that require many years of education for successful participation in work life, adolescence is greatly extended. Describe physical changes associated with puberty, including hormonal changes, changes in body size, body proportions, and muscle-fat makeup, and sexual maturation. Hormonal changes under way in middle childhood initiate puberty, on average, two years earlier for girls than for boys. The first outward sign is the growth spurt. As the body enlarges, girls" hips and boys" shoulders broaden. Girls add more fat, boys more muscle.
