Brief Summary
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.

Day 7 (EEG + Modafinil Appointment)
Electroencaphalography (EEG) - Resting alpha synchrony
The EEG will measure resting state alpha synchrony in the brain. The primary outcome will be differences in EEG activity before and after modafinil administration.
Day 7 (EEG + Modafinil Appointment)
Electroencaphalography (EEG) - Oscillatory frontal gamma synchrony
The EEG will measure oscillatory frontal gamma synchrony in the brain. The primary outcome will be differences in EEG activity before and after modafinil administration
Day 7 (EEG + Modafinil Appointment)
Electroencaphalography (EEG) - Task-related reward positivity/P900
The EEG will measure task-related reward positivity/P900 activity in the brain. The primary outcome will be differences in EEG activity before and after modafinil administration
Day 7 (EEG + Modafinil Appointment)
Electroencaphalography (EEG) - N1 amplitude
The EEG will measure N1 amplitude in the brain. The primary outcome will be differences in EEG activity before and after modafinil administration
Day 7 (EEG + Modafinil Appointment)
Dot Pattern Expectancy variation (TOPX) Task - Accuracy
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. Performance is assessed based on accuracy of responses. The primary outcome will be differences in task accuracy before and after modafinil administration.
Day 7 (EEG + Modafinil Appointment)
Dot Pattern Expectancy variation (TOPX) Task - Response Time
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.
Day 7 (EEG + Modafinil Appointment)
Translational Bandit Task (TBT) - Accuracy
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.

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 delay between the presentation of stimuli and the selection of the response. The primary outcome will be differences in task performance before and after modafinil administration.
Day 7 (EEG + Modafinil Appointment)
Translational Bandit Task (TBT) - Reward Seeking Behavior
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.
