In this study, investigators will examine the behavioral effects and neurophysiological mechanisms of the pro-social neuropeptide oxytocin in patients with recent-onset schizophrenia and other psychotic disorders. Such research is a necessary first step towards identifying whether intranasal oxytocin administration can serve as an adjunct treatment for social impairments in schizophrenia and other psychotic disorders.
Aim 1: To quantify the effects of exogenous oxytocin on social cognition and behavior in patients with recent-onset schizophrenia.
Hypothesis A: Patients and healthy comparison subjects will show enhanced social cognition (e.g., improved interpretation of paralinguistic and emotional cues, such as those involved in emotional or sarcastic communication) after administration of oxytocin versus placebo.
Hypothesis B: Patients and healthy comparison subjects will show increased attention to others' eyes and patients will exhibit increased facial affect expressivity after administration of oxytocin versus placebo.

- Change in Social Cognition Task Performance [ Time Frame: Through study completion, 2-3 weeks ]Participants will undergo computer tasks that measure social cognition. Tasks will involve verbal responses, pressing buttons at specific times, listening, and viewing audio-visual stimuli. Investigators will be measuring the difference in accuracy and verbal content of the responses on the oxytocin day compared to the placebo day.
- Physiological Measurements [ Time Frame: Through study completion, 2-3 weeks ]Sensors will be attached to measure heart rate, respiration, and skin conductance during computer tasks.
- Questionnaire [ Time Frame: At baseline visit, up to 4 hours ]Participants will be asked questions about their current positive and negative symptoms, medical and psychiatric history. Self-report responses will be saved in writing or audio recording.
