A researcher tested 40 adults. Each adult had to rate their mood after listening to a tape of people being sick, and then again after a tape of people laughing. Half of the participants were asked to visualize the people that they could hear on the tape, whereas the other half just listened. What experimental design has been used?

This is a mixed design because it involves both within-subjects (each participant rates their mood after listening to both tapes) and between-subjects elements (participants are divided into two groups based on whether they visualize the people or just listen).
