简要总结
The goal of this clinical is to learn more about decision making in psychosis spectrum disorders, like schizophrenia. The investigators will ask people who do not have psychosis to take a single dose of modafinil and then complete some brain games on the computer that measure decision making. They hope to improve our understanding of psychosis to help people in the future. The main research questions are:
Does a single dose of modafinil change how people play the brain games? Does a single dose of modafinil change brain activity?
Participants will:
Complete an interview and self-report questionnaires. Complete safety screening activities, like a blood draw, a urine drug test, and an alcohol breathalyzer test.
Take a single dose of modafinil. Complete brain games while wearing an electroencephalography (EEG) cap, before and after taking the single dose of modafinil. EEG measures electrical activity in the brain.
详细描述
Participants will be asked to complete two appointments in this study. These appointments will ideally be about 1 week apart, but can be up to 1 month apart if needed.
The first appointment is the Intake and Clinical appointment. This visit will take between 30 minutes to 2.5 hours, depending on how many study tasks are needed. Participants in this study may have participated in a sister study, called "State Representation in Early Psychosis 2 (STEP 2)." If so, they will not need to complete many of the intake questionnaires, and it is expected to take about 30 minutes for them to complete this appointment. If they did not participate in STEP 2, participants will need to complete the full intake battery.
During the interview, the investigators will ask questions about a participant's medical and psychiatric history, and current and past mental health symptoms. The investigators will collect demographics, as well as information on the person's social life and quality of life. After the interview, they will complete brain games on their computer.
The second appointment is the EEG + Medication appointment. Participants will come in person to the MHealth Fairview Riverside Campus. The visit will take place in the University of Minnesota Department of Psychiatry. This visit will take about 4-4.5 hours.
First, the investigators will complete safety screening measures. This will include:

Dot Pattern Expectancy variation (TOPX) Task - Response Time
时间窗: Day 7 (EEG + Modafinil Appointment)
The TOPX task consists of a series of pattern sequences. One pattern is designated the "A" cue, and another the "X" cue, which requires one response (AX, 60-70% of trials, e.g. respond with the left button), while other sequences require a different response (AY or BX, 12-15% of trials each, or BY, 6-10% of trials, e.g. respond with the right button). Given the strong expectation that X's evokes a valid response, BX trials place demands on the fidelity (stability, memory) of the "B" cue state representation to overcome this tendency. Response time performance is assessed based on the delay in the presentation of the stimuli and the selection of the response. The primary outcome will be differences in response times before and after modafinil administration.
Translational Bandit Task (TBT) - Accuracy
时间窗: Day 7 (EEG + Modafinil Appointment)
This is a task variant that uses choice options (neutral images) that are rewarded probabilistically. The rewarded stimulus with the highest reward is changed over time. State learning associated with staying or switching stimuli too quickly (lose-switching) can be evaluated. Performance is assessed based on selection of the option that will yield the highest reward. The primary outcome will be differences in task performance before and after modafinil administration.

Given the strong expectation that X's evokes a valid response, BX trials place demands on the fidelity (stability, memory) of the "B" cue state representation to overcome this tendency. Performance is assessed based on accuracy of responses. The primary outcome will be differences in task accuracy before and after modafinil administration.
Translational Bandit Task (TBT) - Reward Seeking Behavior
时间窗: Day 7 (EEG + Modafinil Appointment)
This is a task variant that uses choice options (neutral images) that are rewarded probabilistically. The rewarded stimulus with the highest reward is changed over time. State learning associated with staying or switching stimuli too quickly (lose-switching) can be evaluated. Performance is assessed based on the behavior of reward seeking-whether participants "explore" to find new reward scenarios, or if they stay to "exploit" a known reward scenario. The primary outcome will be differences in reward seeking behavior before and after modafinil administration.
