Beskrivning
Inclusion Criteria:
- Between the ages of 18-60.
- Meets DSM-5 criteria for schizophrenia, schizoaffective disorder, or schizophreniform disorder.
- Currently attends the Rutgers UBHC Partial Hospital Program and plans to continue attending for at least the next 16 weeks.
- If the participant is treated with antipsychotic medication, he/she is on stable treatment with this medication (i.e. no change in medication type, or substantial change in dose, for at least 4 weeks prior to participating in the study and no anticipated change for the next 16 weeks).
- Has capacity to provide informed consent.
- Is fluent in English.
- Has a minimum binocular visual acuity of 20/100, as assessed at baseline using a standard eye chart, with the participant's typical vision correction (e.g., with glasses if the participant typically wears glasses).
Exclusion Criteria:
- Has met DSM-5 criteria for a substance-use disorder within the last 12 months (with the exception of tobacco use disorder, which will be permitted).
- Has a verbal IQ score of < 70 per the Wechsler Test of Adult Reading (WTAR).
- Current or recent history of a medical condition that significantly affects the structure or function of the brain or eye (e.g., ocular or retinal disease, thyroid disease, untreated hypertension, uncontrolled diabetes).
- Current or past neurological or neurodevelopmental disorder such as seizure disorder, cerebral palsy, intellectual disability, or pervasive developmental disorder.
- Has a "lazy eye" or history of severe eye injury.
- Has received electroconvulsive therapy within the last 8 weeks.
- Has a history of head injury with loss of consciousness lasting more than 10 minutes or with neurobehavioral consequences of the injury (e.g., need for follow-up treatment, cognitive or behavioral changes following the injury, etc.).
- Any current use (last month) of non-prescribed amphetamines, opiates, cocaine, sedative-hypnotics, and/or cannabis.

Experimentell: visual training condition
Participants in the visual training condition will participate in the visual training (VT) group, during which they will complete computerized visual training that targets low- and mid-level visual processes.
Each group will include a maximum of 3 participants and will meet 3 times a week over a period of 12-14 weeks.
|
The computerized visual training (VT) program that is being evaluated was developed by Aaron Seitz, who is a co-investigator on this project; it includes 1) ULTIMEYES, which targets broad-based visual functions, including low-level processes (e.g., visual acuity, contrast sensitivity), and 2) visual perceptual organization exercises, which target mid-level visual processes.
Both elements of the program also involve higher-level visual functions, such as visual search and visual attention.

|
Inget ingripande: control condition
Participants assigned to the control condition will receive standard Partial Hospital care without visual training.
