Neural Mechanisms of Cognitive Inhibition in Youth with and without a Trauma History

Principal Investigator

Kristen Mackiewicz Seghete

Study Purpose

The goal of this project is to examine how brain activity changes in adolescents. Researchers are examining stress, life experiences, and brain and behavior changes in youth age 13-17. We will use a series of scanner activities, questionnaires, and behavioral tasks that utilize brain regions that are developing during this age range. We will also examine how various clinical and psychosocial variables impact brain activation.

Medical Condition(s)

No medical conditions are being studied.

Eligibility Criteria

Eligible participants will be between the ages of 13 and17 years old, right handed, with no braces or permanent retainers.

Age Range

13 - 65

Healthy Volunteers Needed


Duration of Participation

The participant and a legal guardian will complete initial phone interviews to determine initial eligibility. If the youth is eligible, the youth and at least one legal guardian will come in for more detailed interview sessions lasting 60-90 minutes. Eligible participants will be invited for a puzzles and games session (3 hours) and a scanning session (approximately 2 hours). Sessions may be completed in two or three visits at participant’s convenience. Study participation will be 6-7 hours in total. Participant may elect to be enrolled in follow up interviews one at 6 months and 1 year after the initial study visit. Follow up interviews (10-30 minutes) will be conducted in person at OHSU with participants enrolled through CARES and over the phone with participants enrolled through the community.
