The use of binaural beats—auditory illusions created by presenting slightly different frequencies to each ear—has been promoted as a tool for enhancing cognitive performance and memory. While some claim these beats can boost focus and recall, do they actually improve short-term working memory under controlled laboratory conditions? Psychologists want to use the laboratory experimental method to investigate whether participants achieve a higher working memory capacity when listening to beta-frequency binaural beats (20 Hz) compared to listening to standard white noise.
Explain how you would conduct a study using the laboratory experimental method to investigate if there is a difference in working memory performance (measured via digital sequence recall) when listening to beta-frequency binaural beats compared to standard white noise. Justify your decisions as part of your explanation.

You should use your own experience of practical activities to inform your response.
