General Description of 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 59 multilingual instruments covering work,health and education and categorised as Intellingence, General Ability, Special Ability, Personality Structure, Attitudes and Interestsand Clinical tests. Those tests that are produced in the English Language and have not been reviewed elsewhere in these reviews will be reviewed here as individual tests. The MTA is a measure of mechanical-technical understanding and is one of the Vienna Test System tests that is administered, scored and interpreted using a computer. It can be used alone or as part of a battery of tests chosen according to need, from the entire set of Vienna tests. This test has been designed to measure 3 of the 4 abilities that contribute to mechanical comprehension as defined by Pauli and Arnold (1972). These are 1) the ability to understand and describe technical drawings or instruments and to describe their usefulness, 2) the ability to recognise the functional importance of the individual parts and to explain their co-action, and 3) the ability to correctly understand and describe technical laws (e.g. the effect of the lever), with which everyone is acquainted in daily life. The author was also influenced by Kraak (1961), who stated that spatial perceptive ability, (factor K in Vernon’s hierarchical model of intelligence), was a pre-requisite for technical reasoning. There is one primary scale derived from 16 tasks (items). Each item consists of an image with 2 or more parts that move simultaneously in the same or different direction (up or down, left or right), and 4 plans of wheels, axles, threads and bars, which may or may not allow the sequence of movements as in the given moving image. The task in the first subset is either to identify which plan is incorrect, or to say that all are correct. In the second subset the task is to identify which plan is correct or to say that all are incorrect. The scores derived from the two subtests, and the time taken to complete the test is used to indicate whether the subject has fully understood the instructions. There is a practice test before each subtest. Each item with the subtests is timed (2 minutes maximum). On completion, the results are calculated instantly by the computer, using the standardisation sample norms, but there is the facility to use gender, educational or age related norms. Interpretation guidelines are limited to the general comments in the manual, and are not specific to a particular subject’s score.
