The "Stages of Development" refer to the various phases individuals go through as they grow and mature. These stages can be categorized into physical, cognitive, and emotional development. Each stage is characterized by specific milestones, such as infancy, childhood, adolescence, and adulthood, which reflect changes in abilities and behaviors. Understanding these stages helps in recognizing how people learn and adapt over time. For example, during infancy, a child develops basic motor skills, while in adolescence, they experience significant emotional and social changes. These stages are essential for educators, parents, and psychologists to support healthy development.
