In a nutshell: Developmental psychology studies how people change and grow throughout life.
## Growing Up, Psych Style
Developmental psychology looks at how we change from infancy to old age. It explores physical, cognitive, and social changes.
### Stages of Development
- **Infancy and Childhood:** Learning to walk, talk, and interact.
- **Adolescence:** Figuring out identity and independence.
- **Adulthood:** Managing relationships, careers, and aging.
### Key Theories
- **Piaget’s Stages of Cognitive Development:** Children think differently at each age.
- **Erikson’s Stages of Psychosocial Development:** Each stage has its own challenges, like trust or identity.
## Why It Matters
Understanding development helps teachers, parents, and even employers support people at different life stages.
Examples
- A child learns to share toys as part of social development.
- A teenager questions who they are, searching for their identity.
