What Is a Psychomotor Test?

The psychomotor ability test is less effective than the mechanical and clerical ability tests. It is better for predicting the performance in the training plan than for predicting the achievement of work, and it is more effective for predicting the success of repetitive work. But it is relatively poor at predicting the success of some complex tasks that require higher cognitive and perceptual abilities. Generally speaking, the validity of the comprehensive exercise test is higher than that of the simple exercise test.

Validity ratio of psychomotor ability test

Psychomotor ability tests are further divided into large-scale exercise tests, fine exercise tests, and a combination of the two. Most of these tests are speed tests whose scores are related to the time it takes to complete the task and are suitable for both adolescents and adults. Generally this kind of test relies on the instrument, but also in the form of pen and paper. Some paper-pencil tests have better predictive validity, but there is currently evidence that there is little correlation between paper-pencil tests and instrumental tests used to measure the same type of athletic ability.

1. Big Motion Test

A test that measures the speed and accuracy of large movements of fingers, hands, and arms. The most common is the Stromberg Dexterity Test (produced by EL Stromberg). This test requires participants to arrange as quickly as possible 54 colored biscuits in the specified order; another common test is Minnesota Operating speed test (Minnesota Mechanical Assembly Test), this is a manual agile test, including a board with 60 holes and red and yellow wooden blocks, divided into 5 sub-tests, namely the installation test, flip test, removal Quiz, one-handed flip and placement test, two-handed flip and placement test. In these sub-tests, it is required to flip, move, and place the wooden block in the specified manner. For example, the placement test requires the test subject to place the wooden block in the hole. Scoring takes into account the time to complete.

2. Minor Movement Test

Measure the speed and accuracy of small movements. Common O'Connor finger test and O'G. Paterson test. The test requires the finger or pair of tweezers to place a small copper nail into a small hole in a fiberboard. There is also the Crawford Small Parts Dexterity Test. In the first part of the test, the tweezers tried to insert the nails into the holes and put a small ring on each nail; in the second part, put the small screws into the screw holes and tighten with a screwdriver. Test scores are calculated as the time to complete each section. The half-reliability of the test is about 0.85, but the correlation between the first and second parts is only 0.40. Although it can be estimated that the test scores will be related to the performance of certain occupations that require fine movement agility, such as lettering, there are no reports of such evidence of validity.

3 Big and small movement test

Simultaneously measure both hand and hand movements and finger agility. The common one is the Purdue Pegboard test, which does not use tools. The first part requires the right, left, and both hands to be used to insert the nail into the hole; the second part requires the nail and copper ring to be placed together in the hole, and both hands can be used at the same time. There are also Pennsylvania Bi-Manual Worksamples (prepared by JRRobert) and Bennet Hand-Tool Dexterity Test (prepared by GK Bennett). For both tests, nuts and bolts are used. The former requires the tester to screw 100 nuts on the 100 bolts and then insert them into the holes. The latter requires the tester to first place three different specifications on the left side of the toolbox Unscrew the 12 nuts from the bolts and install them on the right plate. Scores are calculated based on the time it takes to complete the test.
