Human development focuses on the physical, cognitive, social, intellectual, perceptual, personality and emotional growth and changes that occur across the lifespan. There are several key developmental stages from pre-natal to old age, each with distinguishing characteristics. These stages include pre-natal development where all body features are developed, infancy which is the foundation age, early childhood where language and reasoning are acquired, and adolescence where sexual maturation and rapid physical development occurs.
