2.1. Participants

Forty‐five participants enrolled in an institutional review board‐approved protocol at the National Institute of Mental Health in Bethesda, MD. Participants provided written informed consent. All participants were >18 years old (Age: M = 31.95 years, SD = 9.39; 58% female). Participants were excluded for any current psychiatric conditions, as determined by the Structured Clinical Interview for DSM‐IV Disorders (Spitzer, Williams, Gibbon, & First, 1992). Further exclusionary criteria included IQ < 70 on the Wechsler Abbreviated Scale of Intelligence (WASI; Wechsler, 1999), alcohol or substance abuse within the last 3 months, significant medical illness, head trauma, neurological disorder, current psychotropic medication use, or contraindications to MRI.

Of the 45 individuals who enrolled in the study, 40 participants (Age: M = 31.76, SD = 9.43; 58% female; IQ: M = 114.70, SD = 11.16; 38% White, 33% Black or African American, 13% Asian, 16% other) provided useable behavioral and imaging data for at least two sessions for at least one of the two task paradigms. Participant data with excessive head motion or poor task performance were excluded (Section 2.5.3). Participants with only one useable scan after scan quality assessment were excluded. The final number of participants included in all analyses for the visual search task was N[Session 1–3] = 40, 35, 33 and for the emotion labeling task: N[Session 1–3] = 29, 33, 30 (Figure S1).
