Primary Investigator
Brief description of study
Why is this study being done?
The purpose of this study is to understand how movement and sensory characteristics (e.g., posture, walking, hand and arm based reaching) present in psychotic disorders over time.
Who can take part?
We are looking for healthy individuals, ages 18-55, who have never been diagnosed with psychosis.
Detailed description of study
What will happen during the study?
If you are eligible and choose to participate, you will be randomly assigned, like the flip of a coin, to 1 of 2 study groups:
- Group 1 includes just one set of study assessments; for most participants, Group 1 can be completed in a single study visit.
- Group 2 includes more than one part, completed across different study visits; if assigned to Group 2, you will return to the lab 5 times over 6 months.
- For either group, you will do some tests on the computer, as well as some paper and pencil tests, and some active movement tests where you will make hand or walking movements.
- You will be asked to answer questions about your emotions, thoughts, and experiences, and if you have a psychiatric diagnosis, asked additional questions about symptoms.
- Additionally, you will receive a brain scan.
- If in Group 2, these parts of the study will be repeated at different study visits over 6 months.
- Study visits occur in person at our lab in Bloomington, Indiana, Department of Psychological and Brain Sciences at Indiana University Bloomington. Address, 1101 E 10th St. Rm. A208A
- Each study visit is expected to last between 2 to 5 hours.
Incentive/compensation
- You will receive $15/hour for participating in the clinical assessments, self-report questionnaires, and motor/cognitive tasks.
- You will also receive an additional $30/hr for time participating in neuro-imaging.
