Question

Longitudinal studies can suffer from biased sampling or cohort effects, which can distort age-related changes. Biased sampling can occur if the sample is not representative of the larger population or if individuals drop out of the study over time, leading to a non-random sample. Cohort effects can occur if differences between generations, such as cultural or historical events, affect developmental outcomes independent of age.
