First secure some geometrical figures. Take for example a five-pointed star, have the child look at it carefully, then close his eyes and reproduce its form and size in a clear, visual picture. Let him look at the drawing and see if he can improve the clearness and definite proportion of his mind's eye picture. Now have him take a sheet of paper and draw this picture as he sees it in his mind, and when complete compare it with the original for accuracy in size and proportion. Let him close his eyes several times and get just as definite a mind's eye picture as possible before he attempts the drawing of the figure. Practice with figures of this kind, gradually increasing their complexity.
Use Other Simple Objects
Instead of the geometrical figures of the previous exercise, take some simple object, such as a coin, a key, a watch charm, or a book. Follow the same plan as above. Have the child make a complete mind's eye picture, then try to draw it.
Color Practice Valuable
Secure a number of colored objects, such as sheets of paper, or book covers, or candy boxes, anything which is colored. Let the child study the color carefully, then reproduce it in his mind's eye. First he must work with single colors, then combine two or three in a group, and reproduce them in his mind's eye. In following this exercise he will develop an accurate color memory.
Out-of-Door Games
Select a certain tree and let the child look at it intently for a few seconds, then ask him to close his eyes, or look away, and describe the tree to you. Try to get him to see clearly all the detail in his mind's eye picture, as you did in the former exercises for the physical eye.
Use Entire Landscape
In the same way have the child visualize the landscape. Let him look at it intently for a few moments, and then, with his eyes closed, describe it. The description which the child gives will reveal the amount of detail in his mind's eye picture. Try again, and see how much he can add at the second trial.
