Document Summary
Ageism, discrimination against any person, young or old, based on chronological age. Age effects, the consequences of being a given chronological age. Cohort effects, the consequences of having been born in a given yr and having grown up during a particular time period w/ its own unique pressures, problems, challenges and opportunities. Cross-sectional studies, the investigator compares diff age groups @ the same moment in time on the variable of interest. > these studies don t examine the same ppl over time; consequently, they allow us to make statements only about age effects in a particular study/experiment, not about age changes over time. Longitudinal studies, the research selects one cohort. > since each cohort is unique, conclusions drawn f/ longitudinal studies are restricted to the cohort chosen. > selective mortality, a problem w/ longitudinal studies when participants drop out as the studies proceed = nonrepresentative group of ppl who are usually healthier than the general pop n.
