Quizplus · Accepted Answer

This is an experimental study because the researchers are manipulating the independent variable (forcing the rats to go left or right) and observing the dependent variable (differences in times). Observational studies simply observe and record behaviors without manipulating any variables. Longitudinal studies follow participants over time to observe changes or development, which is not the case in this maze experiment.
