Document Summary
Descriptive research design providing information about age differences but not attempting to rule out social or historical factors. Age an objectively determined measure of how many years a person has lived up to the present moment. Cohort term used to describe the year (or period) of a person"s birth. Time of measurement tells us the year or period in which a person is tested. Cohort effects refers to the social, historical, and cultural influences that affect people during a particular period of time: they are normative history-graded influences present at or around the time of a person"s birth. As in bronfenbrenner"s ecological model, time-of-measurement effects may be far removed from the individual, but still impact people indirectly by affecting the conditions that actively impinge on their lives. Longitudinal design people are followed repeatedly from one test occasion to another: researchers aim to determine whether participants have changed over time as a result of the aging process.
