Quizplus · Accepted Answer

Ronan has tested students from different age groups at the same time, which is a characteristic of a cross-sectional research design. Longitudinal research follows the same individuals over time, while sequential design combines elements of both longitudinal and cross-sectional designs. Time analysis is not a commonly used research method in developmental psychology.
