Raven's Progressive Matrices are multiple choice intelligence tests that assess abstract reasoning. Developed in 1936 by John Raven, the tests present patterns in matrices and ask test takers to identify the missing item to complete the pattern. There are three versions for different ability levels: Standard, Coloured, and Advanced. The tests measure two main components of general intelligence: eductive ability to think clearly and make sense of complexity, and reproductive ability to store and reproduce information. Studies have found individuals with autism spectrum disorders can score higher on Raven's tests compared to other tests.
