Description

The introduction explains that life-span development is the scientific study of human growth, change, and stability from conception through the entire course of life. It emphasizes that development is a lifelong process involving physical, cognitive, emotional, social, and behavioral changes that occur from infancy to old age.

The author introduces the idea that every person’s development is shaped by the interaction of biological factors, environmental influences, culture, relationships, and individual experiences. Human development is not limited to childhood; important changes and adaptations continue throughout adulthood and later life.
