Answer :
Final answer:
The research conducted at Stanford University in the 1970s is classified as longitudinal research, which involves observing the same subjects over a significant period. This method allows researchers to track changes and understand development over time. Other research types, like cross-sectional, differ as they assess various groups at a single point in time.
Explanation:
Definition of Research Types
In the early 1970s, researchers at Stanford University conducted a study observing a group of preschoolers over an extended period, following them into adulthood. This type of research is classified as longitudinal research.
What is Longitudinal Research?
Longitudinal research involves repeated observations of the same variables over a long period of time. This method allows researchers to track changes and developments over time, providing insights into how individuals evolve and how various factors impact their lives.
Comparison with Other Types of Research
- Cross-sectional research studies different groups at one point in time rather than the same group over many years.
- Continuous and discontinuous are terms more descriptive of data collecting processes rather than specific types of studies like longitudinal or cross-sectional.
Overall, the study at Stanford exemplifies the longitudinal approach, giving researchers valuable data on early childhood development and its long-term effects.
