1. Normative age-graded influences generally happen to people in a culture at around the same time. For example, in the United States, the age at which one experiences first marriage, first menstruation, and menopause are examples of normative age-graded influences. These might also include social events like the age at first marriage or graduating from college. Normative history-graded influences happen to people living at a certain time. For example, epidemics, droughts, economic collapses, and wars would fall into this category. Nonnormative influences are those that are important to one person but don't happen to most people. For example, being nominated for President, winning the lottery, contracting a rare disease, or being in a plane crash would fall under this category. Events in each category, whether they are positive or negative, all impact development.
