Test #7A: Draw It

See how long you can retain a visual image. You can do this as a series
of tests or you can draw two, three, or four images at the same time.
Look at each image below for 30 seconds and remember as much
as you can. Then, close the book and try to draw it from memory.
Next, without looking back at the image or your drawing, do something
else for 30 minutes and try to draw it again. Compare your two
drawings to the original to see how much you remember. Then, try
the same test 30 days later and see how your second set of drawings
compare to your first test. 57
