Stress & Self-Control Costs

Self-control failures are a universal challenge for healthy and clinical populations. Recent work suggests these failures may arise from excessive cognitive costs associated with exercising self-control, yet the mechanisms underlying these costs are unknown. To address this, the investigators will use a validated decision-making task that measures how much individuals will pay (from a study endowment) to restrict access to tempting rewards that may lead to self-control failures. The investigators will examine these costs to identify their cognitive, neural and affective mechanisms. First, the investigators will identify the cognitive and computational mechanism that gives rise to self-control costs. Second, the investigators will characterize the neural correlates of self-control costs and identify neural mediators and connectivity patterns stemming from these costs. Finally, the investi
