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. Cognitrone (COG) is one of 8 General Ability Tests within the fully computerised Vienna Test System. It is a general performance test for the assessment of attention and concentration based on Reulecke's (1991)theory of concentration. There are forms of the test which can be administered to adults and to children from four years of age. The tests involve the presentation of abstract figures on which the test taker makes a judgment concerning their congruence. Items are presented on screen and the test takers respond using either a computer keyboard or the VTS work panel. Each test begins with an animated instruction phase and an error sensitive practice phase. There are ten test forms (S1-S9 and S11) which differ in terms of item difficulty, number of items, working time limit and number of figures in the display field. Seven of the test forms have an unlimited working time (S1-S3, S7-S9, S11) and three test forms have a fixed working time of 1.8 seconds per item (S4-S6). Test forms S1/S4, S2/S5 and S3/S6 differ in terms of the complexity of the patterns. Test form S7 includes only one figure in the display field for the target to be compared to. Test forms S8 and S9 contain simple figures and have an overall time limit of seven minutes. Scoring is computer managed and based on two main metrics, number of correct responses for the timed versions and mean time to respond for the untimed versions. These are both normed using percentiles and T-scores. Some secondary measures are also reported e.g. correct hits versus correct rejections. A computer-generated report of the scores is presented which can be downloaded as a word file.
