A cross-sectional design is most suitable for Professor Sandis's concerns because it is less costly and time-consuming compared to a longitudinal design. It involves observing different subjects of different ages or stages at one point in time, allowing for the study of cognitive abilities across different groups without the need for a long-term commitment.
