In a longitudinal design, a group of participants is followed for a long time. This allows researchers to study changes over time within the same group of people, which can provide valuable insights into development and behavior. A single individual can also be studied in great detail, but this is not characteristic of a longitudinal design. Participants of different age groups can be observed at the same time in a cross-sectional design, but this is not longitudinal. Observing participants without interfering describes a naturalistic observation, which is not necessarily longitudinal.
