Affectionate Writing
Participants assigned to the experimental group will spend 20 minutes writing an affectionate letter to a loved one. Levels of cortisol will be measured using saliva samples from each participant during the writing session. Levels of oxytocin, a hormone known to transmit signals within the brain and often associated with bonding and building trusting relationships, will be measured from blood samples taken during the writing session as well.
Meaningless Writing
Participants assigned to the control group will spend 20 minutes writing about meaningless topics. Participants will undergo the same testing during the writing session as the experimental group.
