Cognitive Strategies in Early Psychosis 2

The goal of this clinical trial is to learn more about decision making in psychosis spectrum disorders, like schizophrenia. Participants will be people who have had symptoms of a psychosis spectrum disorder start within the last five years. The investigators will study how two study agents change decision making in people with psychosis, by asking participants to complete some brain games on the computer before and after taking the study agents. The investigators 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 with psychosis play the brain games? * Does a single dose of d-serine change how people with psychosis play the brain games? * Does a single dose of modafinil change brain activity? * Does a single dose of d-serine 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. * Complete functional Magnetic Resonance Imaging (fMRI) scans. fMRI uses magnets to take pictures of the brain. There will be six scanning appointments in the study, with two scans each. Appointments will be about a month apart. * Take a single dose of a study agent during each scanning appointment. The study agent will be taken after the first fMRI. There are three study agents in total: modafinil, d-serine, and a placebo. Each participant will take each study agent twice during the study. * Play brain games on a computer that measure decision making, thinking, and problem solving skills

Improving Cognition Through Telehealth Aerobic Exercise and Cognitive Training After a First Schizophrenia Episode

The participants in the study will receive psychiatric treatment at the UCLA Aftercare Research Program. All participants in this 12-month RCT will receive cognitive training. Half of the patients will also be randomly assigned to the aerobic exercise and strength training condition, and the other half will be randomly assigned to the Healthy Living Group condition. The primary outcome measures are improvement in cognition and level of engagement in the in-group and at-home exercise sessions. Increases in the level of the patient's serum brain-derived neurotropic factor (specifically Mature BDNF) which causes greater brain neuroplasticity and is indicator of engagement in aerobic exercise, will be measured early in the treatment phase in order to confirm engagement of this target. In order to demonstrate the feasibility and portability of this intervention outside of academic research programs, the interventions will be provided via videoconferencing. The proposed study will incorporate additional methods to maximize participation in the exercise condition, including the use of the Moderated Online Social Therapy (MOST) platform to enhance motivation for treatment based on Self-Determination Theory principles, and a "bridging" group to help the participants generalize gains to everyday functioning. In addition, the exercise group participants will receive personally tailored text reminders to exercise.
