A longitudinal study involves following the same group of individuals over a period of time and assessing changes or stability in a particular variable. In this case, the researchers gave the same group of individuals the SAT test repeatedly over a 6-year period to assess the stability of the scores, making it a longitudinal study. A cohort study involves following a group of individuals with a particular characteristic or exposure and comparing them to another group without that characteristic or exposure, which is not the case in this study. A correlational study involves examining the relationship between two variables, whereas in this study the focus is on stability of a single variable. A cross-sectional study involves comparing different groups of individuals at a single point in time, which is not what is happening in this study.
