Answer:
Periods of Development
Think about the life span and make a list of what you would consider the periods of development. How many stages are on your list? Perhaps you have three: childhood, adulthood, and old age. Or maybe four: infancy, childhood, adolescence, and adulthood. Developmentalists break the life span into nine stages as follows:
Prenatal Development
Infancy and Toddlerhood
Early Childhood
Middle Childhood
Adolescence
Early Adulthood
Middle Adulthood
Late Adulthood
Death and Dying
