Read the following research scenario:

Listening to auditory stimuli such as binaural beats or ambient soundtracks has become a popular method for students seeking to enhance concentration during independent study. However, the academic benefits of these auditory backdrops remain heavily contested. Does the specific frequency of the sound waves, or the distinction between purely instrumental lo-fi music and binaural beats, play a critical role in focus? Perhaps students studying quantitative disciplines (like mathematics) respond differently compared to those studying qualitative disciplines (like literature). There are many unresolved questions regarding how auditory stimulation correlates with cognitive productivity. To investigate this further, researchers want to use a self-report questionnaire to explore the relationship between the use of auditory study aids and self-reported levels of concentration.
