Electroencephalography (EEG) Frontal Asymmetry
大体时间：assessed at baseline (60 min prior to aroma exposure and stress), at the onset of aromatherapy exposure, stress battery (30 min after aroma exposure and during stress), post-stress (60 min after completing stress battery)

EEG frontal asymmetry (FA) is used to assess emotional state.
EEG FA processing was completed by averaging local reference EEG filtered offline from 0.1 to 70 Hz (with 60 Hz notch filter).
5-min data periods during each time were segmented into 2 seconds epochs, and the semi-automatic artifact rejection was applied.
The remaining artifact-free epochs were subjected to Fast Fourier Transform (FFT) .
The power spectra for individual epochs were averaged, and the measures of EEG spectral density were obtained for alpha band (8 -12.99 Hz).
Square root values of power were used, and frontal hemispheric asymmetry was calculated as ((L-R)/(L+R))*100, where L and R are square root values at the homologous left and right hemisphere sites (using local average reference values at F3 and F4).
With this calculation, FA negative values reflect lower alpha power (higher activation) in the left hemisphere linked to a more positive mood.
This is a unit-free measure.

Cognitive Performance: Percent Change From Baseline in Digit Span Backward Task Score
大体时间：Baseline (60 min prior to aroma exposure and stress), post-stress (60 min after completing stress battery)
|
Percent change from baseline in cognitive performance score on the Digit Span Backward (DSB) task.
DSB scores range from 0 to 16, with greater scores indicative of better cognitive function.
Positive change from baseline indicates better functioning.
