Amara decided to investigate how acoustic similarity affects the short-term recall of letters. She conducted a laboratory experiment where she presented participants with a sequence of 10 letters that were acoustically similar (e.g., B, C, D, G, P, T) and a sequence of 10 letters that were acoustically dissimilar (e.g., F, K, Y, W, R, X). Describe an appropriate participant design that Amara could use for this experiment.
