Quizplus · Accepted Answer

This research method involves comparing groups of people of different ages at one point in time, which is exactly what the experimenter is doing by comparing the cognitive skills of 3-year-olds and 7-year-olds. The other options are not applicable: 
- Longitudinal involves following and testing the same group of people over a period of time, which is not the case here.
- Sequential involves combining cross-sectional and longitudinal methods by comparing groups of different ages and following them over time, which is not the case here.
- Clinical involves working with individuals who have specific psychological disorders or issues, which is not mentioned in the scenario.
