Which term describes adolescence marked by the development of secondary sexual characteristics and growth spurts?

• A. Conservation
• B. Identity vs. role confusion stage
• C. Concrete operational stage
• D. Puberty

Answer: (D)

Puberty is the period of adolescence when the body undergoes rapid physical and hormonal changes that lead to sexual maturation. It includes the development of secondary sexual characteristics—such as breast development and other sexual maturation signs in girls, facial and body hair and voice changes in boys—and noticeable growth spurts in height and weight. These changes are driven by hormonal signals that trigger the maturation process, marking the transition from childhood to sexual maturity.

Conservation is a Piagetian idea about understanding that quantity remains the same despite changes in shape, which isn’t about adolescence. The identity versus role confusion stage is Erikson’s psychosocial task focusing on forming a sense of self during adolescence, not the physical changes themselves. The concrete operational stage is Piaget’s stage for late childhood, emphasizing logical thinking about concrete objects, not puberty.
