The investigators hypothesize visual and auditory trainings will be effective as compared to the control games. They also expect that auditory training to be more efficient compared to the visual training because it targets sensory functions that are mostly impaired in schizophrenia, due to auditory hallucinations patients experience. The investigators also hypothesize that both trainings will improve clinical symptoms and quality of life. On a more exploratory analysis, the investigators expect to identify new biological markers of cognitive neuroplasticity, which they expect will differentiate visual and auditory paths.
