Flexible Brain Study


Research suggests that people differ in their brain activity when they engage in a thinking task. You are being asked to participate in this research study because we hope to learn more about how the brain works when we think.

If you agree to participate in this research study, you will be asked to participate in up to eight visits, which will take between 2-3 weeks to complete.


  • Your participation will involve up to eight visits on campus, seven of which will take place in the MRI scanner.
  • We will conduct a variety of cognitive and emotional questionnaires and tasks during the first and last visit.


  • Must be within the following age ranges: 18-35 years old or 55-100 years old
  • Must be right handed and generally healthy
