Opatus CPTA is based on well-founded science and principles. A Continuous Performance Test, CPT, is presented on the mobile unit. Various symbols are flashed on to the screen and the task is to respond (by tapping the screen) to certain symbols (targets), and to not respond to other symbols (non-targets), as quick and accurate as possible. Although a simple task, its limited amusement factor makes it difficult for some to keep up the attention causing erratic responses to be more frequent.
