Brief Summary
The purpose of this study is to examine state representation in individuals aged 18-30 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.

Outcome Measures
Primary Outcomes (2)
Change in Performance of Dot Pattern Expectancy (DPX) Task Variant
The DPX task variant 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.
Baseline, Immediately after the intervention, 5 month follow up
Change in Performance of Bandit Task Variant
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.
Baseline, Immediately after the intervention, 5 month follow up

Study Arms (2)
Visual Perception Training
EXPERIMENTALContains targeted visual perception exercises from BrainHQ's suite of cognitive exercises. This training paradigm is designed to improve state estimation processes at the perceptual input level.
Visual Cognitive Control Training
EXPERIMENTALContains targeted visual cognitive control exercises from BrainHQ's suite of exercises. This training paradigm is designed to enhance state representation stability of visual information.
Interventions
The Cognitive Training is a program consisting of the follow set of exercises developed by Posit Science Corporation (BrainHQ) which is to be evaluated for Visual Perception Training: Visual Sweeps; Mind's Eye; Hawk Eye; and Divided Attention. Participants use a standard web browser on a broadband connected computer and go to the study web site. Participants perform multiple trials over the course of a session, with auditory/visual feedback and rewards to indicate if the trial was performed correctly or incorrectly. After each assigned session, the difficulty of the next session is updated to ensure that each participant is appropriately challenged.

Eligibility Criteria
You may qualify if:
- All Participants:
- Between the ages of 18-30 at the time of screening
- Fluent in spoken and written English, in that the participant learned to speak English before the age of 12 or is able to demonstrate fluency in conversation with study staff
- Has an outpatient status and no hospitalization for psychiatric reasons for at least 1 month prior to participant
- Has access to a computer with internet connection
- Has a United States address as permanent residence
- Estimated IQ at or above 70, as estimated by the cognitive assessments
- Early Psychosis Participants:
- Diagnosis of one of the following conditions (confirmed via interview): schizophrenia; schizoaffective disorder; schizophreniform disorder; Psychosis not otherwise specified (NOS); major depressive disorder with psychotic features; bipolar disorder with psychotic features
- Willing to share contact with a clinical provider
You may not qualify if:
- All participants:
- History of severe substance use in the past 3 months (determined by interview)
- Unable to demonstrate capacity to consent to research, in the judgment of the study team
- Diagnosed with a neurological disorder that would impede participation in the study or would put the participant at additional risk by participating, in the opinion of the PI/CO-Is
- Previous clinically significant head injury or prolonged unconsciousness
- Significant cognitive training experience in the past 6 months
- Meets criteria for clinical risk of suicidal behavior.
- Non-Psychosis participants:
- Meets DSM-5 criteria for a psychotic, bipolar, or autism spectrum disorder
- Has a family history (1st degree relative) of psychosis, bipolar, or autism spectrum disorders
