Brief Summary
This study aims to examine whether listening to natural sounds in a noisy (traffic) environment compared to traffic noise only impacts behavioural, cognitive, affective, and physiological markers associated with attention restoration. Attention restoration will be examined as an aspect of cognitive fatigue.
