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. The Letter Game Prepare a series of white cards about 2 X 3 inches, larger for larger groups, on which are painted the letters of the alphabet in large black type. For this test select a convenient spot, such as the mantel, window sill, or table edge, and place six letters upright and side by side, but do not have the letters spell a word. Each child should be supplied with paper and pencil. All should hold the pencil above their heads. Upon a signal allow the children a five-second glance at the letters. When the five seconds have elapsed give the command "Write," at which each child will write the letters in proper sequence. When they have had ten seconds in which to write, give the command "stop." During the time for writing the letters the cards should be covered. Now the cover can be removed and each allowed to check the result. Begin with the arrangement of about six letters and gradually increase the number and complexity of arrangement so as always to give the child something to strive for. =Only that which requires effort results in growth. Those things for which we strive are of most value to us.= A few examples for the letter game-- M D L T R X X O M E R S E A M N R T V T E X R L O S A X M E V A L R Y A C O P T E L Later arrange some double line combinations, and increase the complexity as the ability develops. Y--E--O--P X--O--J--R M--P--S--Q E--M--T--A B--Z--Y--E R--E--T--W L--V--D--H In some combinations use letters which make the semblance of a word and later some which spell a word. Notice how quickly and easily the combination is remembered when it conveys sense or something definite which the mind can grasp. For example-- T--E--X--O A--M--I--T C--O--C--O B--R--A--S C--R--E--P J--U--B--S F--I--N--O The Number Game In the same manner in which you made the cards for the Letter Game prepare a set on which are numbers instead of letters. Follow the same rules for the Number Game, using rows of numbers instead of letters. First use a row of single digits, increasing it until you have used nine or ten. Then change and arrange a column of two digits, as illustrated below. Later for variety you can combine letters and numbers. In some arrangements leave blank spaces requiring the child to leave the blank in its proper location when reproducing his mental picture. A Few Examples for Guidance
