Developmental factors play an important role in learning as individuals progress through different stages of maturity from infancy to adulthood. At each stage, new capacities and abilities emerge as differentiation, integration, and generalization occur physically, intellectually, emotionally, socially and spiritually. Early learning and development lay the foundation for later stages, so it is important that children receive nurturing environments and educational opportunities to fully realize their potentials. Educators can help facilitate healthy development by understanding developmental stages and providing guidance, training, and remedies tailored to individuals' maturation levels.
