A cognitive psychologist investigated whether a new auditory training app improves working memory capacity in a sample of 20 elderly participants. Using a repeated measures design, the researcher tested all participants' memory recall both before and after they completed a two-week training program. In both tests, participants were asked to recall the exact same sequence of 15 multi-digit numbers.
Explain how two different sets of equivalent digit sequences could be used in this study and why this would be an improvement.
