V. D. L. Adult psychomotor test series for the measurement of manual ability

Abstract

Reviews V. D. L. Adult psychomotor test series for the measurement of manual ability , and V. D. L. Psychomotor test series for children for the measurement of manual ability (1948), by M. J. A. Van Der Lugt. This series of ten relatively simple tests requires only a small amount of test equipment and simple instructions for administration and scoring. The reliabilities for each test are said to be over .90. Five basic components of speed, pressure, accuracy, motor memory and coordination are each represented by two tests, as follows: 1. Speed-prehension; 2. Speed-asynkinesia; 3. Pressure-reproduction; 4. Pressure-control; 5. Accuracy-steadiness; 6. Accuracy-precision; 7. Motor memory-direction; 8. Motor memory-spatial; 9. Coordination-static; and 10. Coordination-dynamic. Although several coefficients of validity are cited, the numbers of cases are described only as small and therefore cannot be evaluated as to their representativeness. The anticipated value of the battery for the appraisal of educational, clinical or developmental status of the individuals should be experimentally verified before we are justified in assuming this type of validity for the tests.
