Final answer:
Stage theories emphasize discontinuous changes while the life-events approach focuses on continuous growth.
Step-by-step explanation:
Developmental psychology is a branch of psychology that studies the psychological growth and development of individuals across the lifespan. It examines the physical, cognitive, emotional, social, and moral changes that occur as people progress from infancy through childhood, adolescence, adulthood, and into old age. Developmental psychologists seek to understand the underlying processes and factors that contribute to these changes.
Stage theories of development emphasize discontinuous changes, whereas the life-events approach focuses on continuous growth.
