Eksperimentel: Stress Condition
The stress condition involved the Trier Social Stress Test (TSST), a standardized laboratory stressor designed to elicit psychological stress and cortisol responses.
Following the TSST, participants were brought to a separate room, instructed to rest and given the option to eat at their leisure.
Books and magazines were included in the room for the participant to utilize.
|
The TSST was 20 minutes long and consisted of a five-minute instructional period where participants listened to a pre-recorded tape; a five-minute speech preparation period; a five-minute challenging serial subtraction task; and a five-minute videotaped public speaking task in front of a panel of three evaluative, non-affirming judges dressed in white coats.

Placebo komparator: Rest Condition
Participants completed a control condition on a separate day.
This condition followed the same sequence of events as the stress condition with the exception that the 20-minute TSST was replaced with a 20-minute low-affect educational film screening.

Salivary cortisol area under the curve
Tidsramme: 2 hours
|
During the control and stress conditions, saliva samples were taken at times 10, 25, 58, 88 and 118 minutes after arrival to analyze cortisol responses to the TSST.
Area under the curve was calculated from the initial cortisol sample collected to the final cortisol sample collected: [AUC=(x2+x1)/(t2-t1) + (x3+x2)/(t3-t2) + (xk+xj)/(tk-tj)].

Salivary alpha amylase area under the curve
Tidsramme: 2 hours

During the control and stress conditions, saliva samples were taken at times 10, 25, 58, 88 and 118 minutes after arrival to analyze alpha amylase responses to the TSST.
Area under the curve was calculated from the initial alpha-amylase sample collected to the final alpha amylase sample collected [AUC=(x2+x1)/(t2-t1) + (x3+x2)/(t3-t2) + (xk+xj)/(tk-tj)].
