Data analyses
Four individuals did not complete the full protocol due to researcher error, participant withdrawal from the study, or computer error, and therefore were not included in data analyses. Two more individuals were excluded from all hormonal analyses due to having baseline or delta hormonal concentrations over three standard deviations away from the mean. One participant was excluded from all hormonal analyses due to saliva samples being heavily contaminated with blood. After excluding these seven individuals, data were analyzed for a total of 149 individuals, of whom 76 (46 women, 30 men) underwent the TSST stress manipulation and 73 (47 women, 26 men) were in the control condition. Of all participants, 81 indicated their relationship status as single, and 68 indicated their relationship status as in a relationship at the time of the study. Of all TSST participants, 40 were single and 36 were in a relationship; of all control participants; 41 were single and 32 were in a relationship.All statistical analyses were carried out with jamovi software (Version 2.2.5.0) [
