Brief Summary

In this study it is aimed to investigate the difference between the brain response to different urban environments in Singapore before and after the COVID-19 pandemic. The datasets acquired from 34 healthy individuals as part of ongoing study "Effects of Landscape on the Brain" (IRB Ref #: S-18-352) will be used. These datasets consist of neurophysiological data recordings and behavioral self-reported measures and were collected before 20 of January 2020. The same experimental protocol would be followed, given that the data collection in the lab-setting would start after 7 th May 2020/whenever research activities are allowed to resume, and the outdoor sessions after the "circuit-breaker" period in Singapore is over.

Conditions

Stress; Anxiety

Keywords

landscape; exposure; EEG; fNIRS; stress; urban; self-isolation; covid-19; pandemic; public space; brain

Outcome Measures

Primary Outcomes (3)

• EEG power in alpha band

  predictor of positive affect and positive mental health outcomes, measured with EEG

  5 minutes

• EEG power in beta band

  more beta in the right temporal lobes associated with stimuli-driven attention, measured with EEG

  5 minutes

• fNIRS haemodynamics

  decreased oxy-hemoglobin in the frontal part of the brain indicates more relaxation

  5 minutes

Secondary Outcomes (2)

• Profile of mood states

  30 minutes

• landscape preference measured with self-assessment manikin scale

  30 minutes

Study Arms (1)

public sp exposures

EXPERIMENTAL

All participants undergo the procedure of visiting all landscape exposures in a random order.

Other: Public space exposure

Interventions

Public space exposure OTHER

landscapes with nature and/or classified as contemplative (through a CLM psychometric measure) are expected to elicit different brainwave oscillations as compared to noncontemplative ones.
