A longitudinal study follows the same individuals over time, allowing for the assessment of stability or change in a particular variable. In this case, the intelligence test results of a single cohort over their adult years would require a longitudinal study to assess stability. A cohort study involves studying groups of individuals who share a common characteristic, while a correlational study examines the relationship between two variables. A cross-sectional study looks at a snapshot of a population at a single point in time, making it difficult to assess changes over time.
