Summary

Eligible participants will come in for three separate visits in which they will be interviewed, perform a variety of tasks, and undergo a non-invasive MRI scan. The investigators anticipate that (1) participants with anxiety and depression will likely perform differently than the healthy controls on cognitive tasks, (2) participants with anxiety and depression will likely show differences in brain functionality compared to the healthy controls, and (3) depression and anxiety likely share some underlying mechanisms.

Detailed description

In order to determine eligibility, a brief phone screen lasting approximately 15 minutes will be conducted. If participants are eligible, they will be asked to come in for three separate visits. During the first visit, participants will complete questionnaires as well as a structured interview with one of the study's staff members at Palo Alto University in Los Altos. During the second visit, participants would come to Palo Alto University in Los Altos and complete questionnaires as well as a testing session involving various tasks. During the third visit, participants would undergo a non-invasive brain scan in which participants would complete a task as well as various questionnaires at Stanford University in Stanford. The investigators have flexible hours and can work around participants' schedules! To inquire more about participation, participants can either email the investigators at [e-mail] or call the investigators at [phone] ext. 3642
