A Test for Order
Allow a third glance at the color strip while you count ten, and have each begin at the left hand end of the strip, noting the arrangement of the colors, and see if they can write accurately the order in which the colors appear on the card.
The first test is for quick reaction of the mind. The amount that they are able to observe in a given length of time will depend upon the rapidity with which their minds react. This test is designed to determine the rapidity of the mental reaction. About thirty-five per cent of those who take it are able to get the correct number, where the number of colors is not more than seven.
The second test is designed to determine the ability of the mind to hold the color impressions. About twenty-five per cent are able to retain the impression of the seven colors.
The third test combines the power to retain the color impression with the ability to retain the correct order. Experience shows that not over ten per cent are able to give the order accurately.
Similar tests repeated will give a great amount of exercise and soon result in a perceptible increase in the power to accomplish the desired results.
