2.3. Procedures
All procedures occurred during a single visit to an observational laboratory over 35 min (After the mental activation phase, the stressor phase began. Participants were randomized to either a social-evaluative stressor or a cognitive stressor. Both stressors lasted approximately 15-min, and physiological data were collected every 3 min. At the end of the stressor, participants completed another self-report survey to indicate post-stressor affect.Participants randomized to the social-evaluative stressor were administered the Trier Social Stress Test (TSST) [Participants randomized to the cognitive stressor completed a mental arithmetic task and a solvable anagram task. During the 12-min mental arithmetic task, participants engaged in a series of subtractions (e.g., subtract seven from 6828) and were prompted to speed up their responses at the start of minutes three, seven, and eleven [
