Summary
This trial will examine how people with/without psychotic illness process information about their environment and if cognitive training can help.
Who is the study for?
This trial is for individuals aged 15-40 with a recent diagnosis of psychosis or related conditions, who speak English and have an IQ above 70. They must be clinically stable, not pregnant, non-dependent on substances, and without major medical or neurological issues.
What is being tested?
The study is testing two types of computerized cognitive training designed to improve information processing in young adults with psychotic illnesses compared to those without psychiatric diagnoses.
What are the potential side effects?
Since the intervention involves cognitive training exercises, side effects are minimal but may include eye strain, headache or fatigue from computer use.

Experimental Treatment
Group I: Visual Cognitive Control TrainingExperimental Treatment1 Intervention
Training will involve maintaining accurate representations of cognitive context (the "rule") in working memory during response selection. On each training trial, participants must observe stimuli, and hold the correct response context "on-line" in order to select the correct response from among the stimuli. Training is adaptive using a staircase function, such that two consecutive correct responses increases either the speed of stimuli presentation or the working memory load via an increased number of stimuli that are presented; one incorrect response reduces the cognitive load. Each session will consist of 45 exercises requiring \~45 minutes.
Group II: Perceptual Discrimination TrainingExperimental Treatment1 Intervention
Training will involve Gabor patch and other visual stimuli discrimination exercises that focus on improving signal-to-noise resolution and attentional control with minimal working memory/cognitive control effects. On each training trial, participants are required to distinguish a target stimulus among a set of distractor stimuli. The similarity between target and distractors increases in level of difficulty based on an adaptive perceptual processing staircase function. Consecutive correct responses lead to increased modulation of the distractors to be more similar to the target, while 1 incorrect response drops the user to an easier level. Difficulty is adapted to maintain an 80% correct response rate. Each session will consist of 4 exercises requiring \~45 minutes. with 40 trials for each exercise.
