Study Details

Study Description

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.

Condition or Disease	Intervention/Treatment	Phase
Cognitive Fatigue Mental Fatigue Behavioral Performance Heart Rate Variability Working Memory	Other: Masking Sound Other: No masking sound	N/A

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.
