Longitudinal research is when the same person or group of people are followed for a period of time. This design is good for questions that ask how an individual changes over time. An example would be to take a group of three-year-olds and measure them yearly to determine when a sense of wrong occurs in their moral development. One advantage of longitudinal studies is that they provide lots of interesting information and truly capture age-related changes; their drawbacks include their expense, the time and effort required to conduct them, and the loss of subjects over time due to various reasons. A cross-sectional design involves looking at groups across different ages at the same time. For instance, you could gather a group of three-year-olds, four-year-olds, five-year-olds, and six-year-olds and see who has developed a sense of wrong in their moral standards. This method tends to be more economical, and you lose fewer subjects; however, it is no longer possible to study change within a specific individual.
