Question

Quizplus · Accepted Answer

Both time-sequential and cohort-sequential designs allow for examining age effects. However, a researcher finding significant age effects in both designs suggests that the aging effects found are not due to historical, social, or cultural factors that differ across time or cohorts. Instead, it suggests that the aging effects found are likely due to personal or developmental factors that change across the lifespan, indicating true personal aging. Therefore, the best choice is C (personal).
