Explain why issues such as commonalities, stability, and change are considered significant in the study of adult development?

Adult development focuses on the behaviors and issues that people deal with during their life span—from adolescence through the end of life (for this course, you will focus more on the retirement age—before sixty-five years). Changes through an individual’s life span are a prominent focus in understanding adult development. Change can be classified as normative and nonnormative age-graded influences.
