Purdue Accuracy Test: What It Is, Works And How It Is Applied

Have you heard of the Purdue Accuracy Test? As the name suggests, the Purdue Accuracy Test is a test that assesses the accuracy of the performer’s movements.

This is a tool that was developed in the 1950s and was initially used in the selection of personnel for jobs that required coordination and skills, but is now used in the field of psychotherapy.

Here, we’ll learn about the features of the Purdue Accuracy Test, the materials needed to perform it, the parts and what the test is all about, as well as how to evaluate it and its possible uses.

    What is the Purdue Accuracy Test?

    The Purdue Accuracy Test is a test developed by industrial psychologist Joseph Tiffin, Department of Industrial Psychology, Purdue University, USA.

    This is allows you to assess coordination as well as two types of manual activity: Thick movements of fingers and arms and fine digital dexterity. On the one hand, it assesses eye-hand coordination, and on the other hand, it assesses the superficial movements of the arms, hands and fingers, and tests the yellow of the finger against finer and more precise movements.

    To perform the Perdue Accuracy test, a number of essential physical elements are required which we will discuss below.

    Material to manufacture

    The Purdue Accuracy Test includes the following components.

    1. A wooden board

    This wooden board has two columns. Each of these columns consists of 25 holes about half a centimeter in diameter.

    At the top of the columns there will be 4 cavities for a specific number of pins, tubes and washers, distributed as follows: at the ends (right and left) the pins will be arranged. In the center are two positions to be occupied, which will be filled as follows: next to the dominant hand, the tubes will be placed, and on the side of the non-dominant hand, the pucks will be placed.

    2. A stopwatch

    The stopwatch is essential to measure the time of each testwhich he trains for the Purdue Accuracy Test, and has an impact on the results thereof.

      Parts of the test

      The test consists of several parts which are summarized here. In all these parts, it is necessary to take into account and report who will have a short time to familiarize themselves with the parts (Tubes, washers and dowels) and practical. The Purdue Precision Test can be viewed as a tool for measuring patient progress.

      1. Part I

      With the dominant hand, they should insert as many pins as possible, within 30 seconds. The idea is to insert the pins as quickly as possible. The exercise is timed, and in the event that a part falls, you should not waste time looking for it, but taking another.

      In this part, what is valued is the coordination of the dominant hand.

      2. Part II

      This part of the test is the same as the first one, except that the non-dominant hand is used to execute. So, with the non-dominant hand, they should insert as many pins as possible, within 30 seconds.

      The person is reminded that they need to go as fast as possible, that they are going to be timed and that if they drop a part, they should not waste time looking for it, but taking another. In this part, what is valued is the coordination of the non-dominant hand.

      3. Part III

      This part follows the line of the previous two. In this case, the person should insert as many pins as possible on both sides, with the use of both hands at the same time, Ditto within 30 seconds.

      He is reminded again that he has to go as fast as possible, that he is going to be timed and finally that if a coin falls on him, he should not waste time looking for it, but taking another. In this part, what is valued is the two-hand coordination.

      4. Part IV

      This last part consists of an assembly task. The idea is to make a coordinated and stipulated sequence which consists of: inserting a plug – a washer – a tube – another washer. This should be done by alternating the use of both hands and always starting with the dominant hand. 60 seconds are available for this test exercise.

      In this last part of the test, what is assessed is the alternating bimanual coordination, so that the person will be informed that while one hand inserts a coin, the other must grab the next coin to insert.

      Assessment form

      The scores, and therefore the results of the Purdue Accuracy Test, are stipulated by the following parameters:

      • For Part I and Part II, the score is the number of pins inserted during the given 30 seconds.
      • For Part III, the total number of pairs is counted.
      • For Part IV, complete couplings and spare parts are explained. So multiply the number of complete assemblies by 4 (which are the parts that make up each assembly) and add the spare parts.

      With all that, variables such as the sex, age or pathologies of the patient are taken into account, So that each person’s percentiles are subject to these variables.

      Uses and applications

      There are several uses for the Purdue precision test app. In the beginning, once designed and created, it can be seen used in personnel selection processes, As it allowed to assess finger ability as well as manual precision.

      These skills are important in handling work, sewing machines, production lines, assembly and maintenance for example.

      But its field of applicability is more closely related to the psychotherapeutic field; it is used in tests for brain damage and brain damage, for people who are going to perform movement therapy (as a tool to assess the patient’s progress), for the diagnosis of learning problems, to assess needs in vocational rehabilitation, and also in the diagnosis of dyslexic people.

      On the other hand, ** is a test of particular interest for occupational therapies **, which are therapies in which various activities are performed.

      These therapies are aimed at people with limitations due to physical damage or illness, disability or cultural impairments, and their objective is to maximize the autonomy of these people, as well as to prevent future disabilities and to be able to stay healthy.
