Neural Mechanisms of Cost and Benefit Integration During Decision-Making, Aim 2: Acute & Lifetime Stress

The CPT involves participants submerging their dominant forearm in ice-water (0-4°C) for 3 minutes.

The control CPT involves participants submerging their dominant forearm in warm water (\~30°C) for 3 minutes.

Participants in the neuroimaging cohort will complete up to two fMRI experimental sessions on different days, with at least a day between sessions, each lasting approximately 2 hours. Imaging data will be collected with a Prisma 3T head- only scanner equipped with a head coil from Nova Medical.
