Question

Quizplus · Accepted Answer

Cross-sectional designs involve comparing different groups of people at one point in time. A cohort effect occurs when differences between these groups are due to the groups having lived through different historical contexts or experiences, rather than the developmental factor being studied. This can confound the results, making it difficult to determine if observed differences are due to the developmental process or to the different experiences of each cohort.
