What is the primary focus of developmental psychology?

Developmental psychology is primarily concerned with the changes in behavior and psychological processes that occur throughout the lifespan. This field investigates how individuals grow and develop, examining physical, cognitive, emotional, and social changes from infancy through old age. By studying these changes, developmental psychologists seek to understand how people develop different skills, beliefs, and behaviors at various stages of life.

While the influence of culture on behavior, environmental effects on mental processes, and strategies to improve mental health are all important areas within psychology, they do not capture the core focus of developmental psychology, which is specifically about the evolution of individuals as they age and mature. Understanding how these changes manifest over time is crucial for providing insights into human development and lifespan psychology.
