Recent neuroscientific studies suggest that listening to specific frequencies of binaural beats can enhance cognitive performance. A cognitive psychologist is investigating whether listening to a 15-minute sequence of 40 Hz beta-frequency binaural beats improves spatial working memory compared to listening to standard white noise. Participants are required to wear electroencephalogram (EEG) headgear to monitor brain activity while navigating a complex virtual reality maze.
