Some tests to assess intelligence and general cognitive abilities are so-called non-verbal tests. That is, they ask participants to solve graphical problems. To do so, no specific language has to be known. It is often claimed that these tests are  appropriate for people from different cultural and educational backgrounds. Therefore these non-verbal tests have also been called culture-fair. The tests below are a selection of current non-verbal tests.
