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 investigators will examine how different classes of stressors (physical, social, or lifetime stress) shape the behavioral and neural representations of self-control costs.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Healthy dieters will undergo a single-visit neuroimaging study where they will first complete demographic and self-report measures followed by a self-control decision task in an fMRI scanner. Prior to scanning, participants will be assigned to a physiological stress group and complete the corresponding stress task. For the physiological stress group, this task is the Cold-Pressor Task (CPT), a physiological stress task in which participants continuously submerge their hand and forearm in ice-water (0-4°C) for 3 minutes. After the scan, participants will wait for 1 hour in an adjacent study room where they will play out one trial of the decision-making task completed in the scanner.
Behavioral: Cold-Pressor Task (CPT) · Device: Functional Magnetic Resonance Imaging (fMRI)
Healthy dieters will undergo a single-visit neuroimaging study where they will first complete demographic and self-report measures followed by a self-control decision task in an fMRI scanner. Prior to scanning, participants will be assigned to the social stress group and complete the corresponding stress task. For the social stress group, this task is the Trier Social Stress Test (TSST), a psychosocial stressor that requires participants perform a short speech and solve math problems in front of 2 evaluative judges. After the scan, participants will wait for 1 hour in an adjacent study room where they will play out one trial of the decision-making task completed in the scanner.
Behavioral: Trier Social Stress Test (TSST) · Device: Functional Magnetic Resonance Imaging (fMRI)
Healthy dieters will undergo a single-visit neuroimaging study where they will first complete demographic and self-report measures followed by a self-control decision task in an fMRI scanner. Prior to scanning, participants will be assigned to the physiological non-stress group and complete the corresponding stress task. For the physiological non-stress group, participants will continuously submerge their hand and forearm in warm water for 3 minutes. After the scan, participants will wait for 1 hour in an adjacent study room where they will play out one trial of the decision-making task completed in the scanner.
Behavioral: Modified Non-Stress CPT · Device: Functional Magnetic Resonance Imaging (fMRI)
Healthy dieters will undergo a single-visit neuroimaging study where they will first complete demographic and self-report measures followed by a self-control decision task in an fMRI scanner. Prior to scanning, participants will be assigned to the social stress group and complete the corresponding stress task. For the social non-stress group, participants will be asked to prepare for a speech that they will practice alone to themselves and complete math problems alone on a piece of scrap paper. After the scan, participants will wait for 1 hour in an adjacent study room where they will play out one trial of the decision-making task completed in the scanner.

The modified non-stress CPT involves participants continuously submerging their hand and forearm in warm water for 3 minutes.
For the modified non-stress TSST, participants are asked to prepare for a speech that they will practice alone to themselves and complete math problems alone on a piece of scrap paper.
Participants will complete the self-control task in the fMRI scanner.
Average Self-Control Cost
The self-control cost is the amount that a participant would be willing to pay to avoid temptation. This will be tested in a self-control task in which participants are shown an images of snack food and report how much they would be willing to avoid the different food items.
Time frame: Day 1
Change in fMRI BOLD Signal During Self-Control Decisions
Functional MRI (fMRI) data will be analyzed to measure changes in blood-oxygen-level-dependent (BOLD) signal in the Dorsal Anterior Cingulate Cortex (dACC), Frontopolar Cortex (FPC) and Orbitofrontal Cortex (OFC) regions of interest as participants make self-control cost decisions during the self-control activity.
Time frame: Day 1 (Up to 1.5 Hours)
