Summary

The purpose of this study is to drive an optimal response to neuroplasticity-based cognitive remediation in schizophrenia in order to maximize treatment response. The investigators will investigate factors that have generally been ignored in prior computer-based cognitive remediation programs-those related to social cognition-- and will delineate their relationship to motivation, functional outcome, and the neural substrates of reward anticipation and emotion processing. Current research indicates that, unless the investigators fully understand and harness these factors, the investigators will not achieve meaningful treatment gains for individuals with schizophrenia.

Conditions

Interventions

OTHER

Targeted Cognitive Training

At present, the TCT exercises consist of three modules: an Auditory Processing Module (40-50 hours of training); a Visual Processing Module (30 hours); a Cognitive Control Module prototype (20 hours). \[Based on the results of our current RCT, Posit Science has revised aspects of the training modules in order to further optimize its effectiveness for treatment of schizophrenia. In this study, we will use updated versions of the training software: an Auditory Module (30 hours), and a Visual Module (30 hours). Features from the Cognitive Control module prototype have been expanded and incorporated into these new modules.

OTHER

Social Cognitive Training

We developed a systematic approach to basic training in facial emotion identification and discrimination and simple social perception and theory of mind tasks using components drawn from three commercially available software packages: the MicroExpressions Training Tool and The Subtle Expressions Training Tool (METT and SETT), plus the MindReading program. Training begins with simple emotion identification tasks, and slowly progressed to more difficult tasks that required subjects to discriminate between two subtle emotion expressions, and to correctly interpret the emotional significance of brief social scenes. A total of 10 hours of training occurred over 8 weeks.
