Behavioral and fMRI studies of cognition in healthy individuals and patients with anxiety
Study Description The current study is a neuroimaging study involving fMRI. Specifically, we seek to examine the neural mechanisms underlying switching attention between internal thought, such as imagination, and external stimuli.
For OCD patients, participation consists of 2-3 sessions totaling 5-7 hours, and participants are reimbursed at $25 an hour. The first session involves a clinical assessment and paperwork to confirm the patient's eligibility (~3 hours total), and the second session involves completing computer tasks while in the scanner (~2.5 hours total). Payment is given to participants in cash upon completion of their participation.
