Conditions
Brief summary
This study aims to examine whether listening to natural sounds in a noisy virtual reality environment compared to no natural sounds influences physiological markers.
Detailed description
The investigators hypothesize that listening to natural sounds has restorative effects on attention by supporting greater use of involuntary attention. This generates the prediction that exposure to natural sounds in the context of a noisy environment will have greater restorative effects on attention (i.e., physiological) as compared to the control group (exposed to noise only). Individual differences (i.e., age, gender, caffeine and food intake, body mass index, skin temperature, noise sensitivity, sleep quality, baseline physiology and behavioural performance) will be examined and accounted for.
Interventions
