Developmentalists who ascribe to the normative-stage model believe that people continue to follow a sequence of age-related changes throughout adulthood. These changes may vary from culture to culture, but typically include stages such as early adulthood, middle adulthood, and late adulthood. While the changes that occur during these stages may be less dramatic than those during childhood and adolescence, they are still considered important markers of development.
