Description of the Test:

The Vienna Test System is a computerised collection of tests and assessments that can be used alone or combined as batteries of tests. The system contains 74 instruments covering work, health and education and categorised as Intelligence, General Ability, Special Ability, Personality Structure, Attitude and Interests and Clinical tests. Many of the tests are multi-lingual with the majority being in German and English. Those tests that are produced in the English Language and have not been reviewed elsewhere are reviewed here as individual tests. Vigilance (VIGIL) is one of 8 General Ability Tests within the fully computerised Vienna Test System. Vigil is a test of sustained attention under continuous stress in the from of sustained vigilance in a situation with few stimuli. Test can be used with adults and children from six years of age. During the test, a flashing dot travels along a circular path in small jumps. Occasionally, the dot takes a double jump to which the test-taker reacts via the computer keyboard or the VTS input device. Responding without the input device is possible but not ideal. There are three test forms (S1, S2 and S4) which differ in terms of test length, rate of critical stimuli and display. Test form S1 displays the circular path that the dot is following, making it easier to perceive a double jump. This form also employs a high rate of critical stimuli. Test forms S2 and S4 do not show the circular path and have a lower rate of critical stimuli, with test form S 4 being twice the duration of S2. The scoring is based on number correct/incorrect and reaction time in seconds. Increases in correct answers and in mean reaction time are also measured.
