The National Institute of Mental Health's Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) program was a collaboration between members of academia, industry, and the government, with the goal of furthering the development of drugs for the treatment of the cognitive deficits of schizophrenia. The program led to the creation of the MATRICS Consensus Cognitive Battery (MCCB), which measures functioning across various cognitive domains, such as attention, working memory (verbal and nonverbal), learning (verbal and visual), reasoning and problem solving, and social cognition. Its measurements are based on timed paper and pencil, computerized, and orally administered tests, as well as spatial tests using geometric cubes.
