Give examples of normative history-graded influences for four generations of a young college student's family. Possible historical events:

1. Great grandparents who endured the "great depression."

2. Grandparents who served during the Vietnam war.

3. Parents who served during Desert Storm.

4. Young adult who now serves in Afghanistan.

Explanation:

Normative age-graded influences are those influences within the life course that are correlated with chronological age. For example, marriage and retirement are two normative age-graded influences. These influences are the result of either biological or environmental determinants or an interaction of the two.
