|Condition or disease||Intervention/treatment||Phase|
|Schizophrenia||Behavioral: Visual Training||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||40 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Half of the participants will be randomized to receive the computerized visual training, which will be delivered in small groups over a period of 12-14 weeks, and the other half will be assigned to the control condition, which consists of standard Partial Hospital care without visual training.|
|Masking:||Single (Outcomes Assessor)|
|Masking Description:||All participants will be assessed on outcomes of interest by trained clinical interviewers who are blind to the treatment condition in which participants are assigned.|

Experimental: 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.
Behavioral: Visual Training
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.
No Intervention: control condition
Participants assigned to the control condition will receive standard Partial Hospital care without visual training.
- contrast sensitivity [ Time Frame: approximately 14 weeks (baseline and post-treatment) ]A measure of low-contrast stimulus detection; contrast sensitivity thresholds at varying spatial frequencies will be examined.
- contour integration [ Time Frame: approximately 14 weeks (baseline and post-treatment) ]A measure of visual perceptual organization; total number correct, adjusted for guessing, will be examined.
