简要总结
This study aims to examine whether listening to natural sounds in a noisy outdoor environment compared to no natural sounds influences behavioural, cognitive, affective, and physiological markers.
详细描述
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 outdoor environment will have greater restorative effects on attention (i.e., physiological, affective, cognitive, and behavioural) as compared to the control group (exposed to environmental 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. Environmental factors (i.e., outdoor humidity, temperature, and noise) will also be accounted for.
