This is an example of a __________ study.

Answer 1

The Harvard's Study of Adult Development discussed in Robert Waldinger's Ted Talk is an example of longitudinal research. This method follows the same individuals over a long period and is valuable for studying changes over the lifespan.

Step-by-step explanation:

Robert Waldinger's Ted Talk about the findings from the Harvard's Study of Adult Development is an example of a longitudinal research study. This type of research design involves following a group of research participants for an extended period of time. The study has provided valuable insights into physical and psychological changes over the lifespan by continuously collecting data from the same individuals.

In contrast to cross-sectional research, which compares different segments of the population at the same time, longitudinal research tracks the same group over time, thus providing a more accurate depiction of changes without the confounding variables of cohort effects. It's an advantageous method for understanding the progression of various factors throughout an individual's life.
