This is an iOS version of audioverbal and visual span tests. This application is intended for neuropsychologists, neurologists and psychologists who need an automated verbal or visual span test for assessment of patients or research. There are also some older variants (mainly for historical reasons) such as the Knox imitation cube test, Kessels standardized variants, and Buschkes 1963 missing scan test. There is also a manual Corsi span test (forward and backwards).
