A cognitive psychologist investigated whether short-term spatial working memory is affected differently by a 15-minute bout of high-intensity cycling compared to a 15-minute guided mindfulness meditation session. The researcher used an independent groups design.
In Condition A, participants completed 15 minutes of high-intensity cycling and then immediately took a computerized 15-point spatial grid recall test.
In Condition B, participants completed 15 minutes of guided mindfulness meditation and then immediately took the same computerized 15-point spatial grid recall test.
Explain two reasons why it was more appropriate to use an independent groups design than a repeated measures design in this study.
