The main problem with a cross-sectional method of analysis in investigating aging is that it confuses cohort effects with age changes. This occurs because the method involves comparing different age groups at one point in time, which makes it difficult to determine whether differences in behavior or cognitive performance are due to age or other factors like social, cultural, and historical differences among people of different ages (i.e., cohort effects).
