5. Current DSM-5 diagnosis of a psychiatric disorder (other than nicotine/caffeine use disorders) as determined by history and clinical exam including substance use disorder, alcoholism and alcohol dependence. Past history of a mental disorder as defined by DSM-IV or DSM-5 will be excluded only if it was severe enough as to require hospitalization (any length), or chronic medication management (more than 4 weeks), or that could impact brain function at the time of the study. Subjects receiving psychotherapy may be included in the study.
6. Those with a binge drinking history every month continuously for the last 10 years will also be excluded. Binge drinkers are those who being female consume 4 or more drinks and males consume 5 or more drinks in one occasion at least once a month.
7. Serious neurological disorder such as MS, Parkinson s Disease, ALS, sensory loss or peripheral neuropathy.
8. Currently taking any psychoactive drugs such as Celexa (TM), Prozac (TM), Wellbutrin (TM), Zoloft (TM), and/or stimulants other than caffeine such as Adderall (TM), Dexedrine (TM) and Ritalin (TM). Subjects taking PRN medications (e.g., sleep medications) may be included in the study.
9. Clinically significant laboratory or examination results.
10. Study investigators and staff, as well as their superiors, subordinates and immediate family members (adult children, spouses, parents, siblings).
11. \*Non-English speakers (must also be able to read and comprehend English).
* The intent of the research has no prospect of direct benefit to the subject. Therefore, we are excluding non-English speakers in this research study since our fMRI paradigms (particularly the Delay Discounting task) require that the subject be able to speak, read and comprehend English.
Subjects will not be excluded from enrollment onto this study if their urine test or breath alcohol level (BAL) is positive for drugs/alcohol on initial screening. However, if they test positive on scheduled study procedure days involving MRI, the procedures will be postponed and rescheduled. We will allow for up to 3 rescheduled study days that were the result of positive urine drug or BAL screens. If the drug/BAL tests is/are positive on the third rescheduled visit, the participant will be withdrawn from the study.
