1.Open one case lengthwise in front of the subject so that the empty, inclined panel to which the pilot caps are fixed, is nearer the subject. The cases may be given in any order. Before being presented to the subject, the caps should be arranged in random order. A good practice to follow is to rearrange the caps after each test is administered. To do so, after the arrangement of the caps has been recorded, transfer them to the opposite panel in random order. Then close the case and turn it over. It is now ready for future testing.
2.Instruct the subject as follows:
The object of the test is to arrange the caps in order according to color. Please transfer them from this panel (indicate) to this panel (indicate) and place them so they form a regular color series between the two end caps (indicate). It should take you about two minutes per panel. However, accuracy is more important than speed so you will be told when the two minutes are up but the panel will not be taken away from you. Arrange them as best you can, but do not dawdle. Do you understand? Begin.
If the subject does not show comprehension, say,
Take the cap which looks most like that (indicate a pilot cap) and place it there . . . and the cap most like that (indicate the last one) and place it there, and so on.
3.Allow the subject as long as necessary to arrange the caps in an order with which they are satisfied. If two minutes have passed, and the subject is not through, quietly remind them that two minutes are up, and allow more time to finish the task.
Record the time taken to complete the test.
