Insight learning is common in humans, but it requires preparation. Do not expect an insightful answer to a test question to appear if you have not studied the material. Many instances of insight appear after one has worked long and hard on a problem. Then, upon relaxing or sleep the solution suddenly appears. The mathematician Fermat, for example, supposedly solved a difficult problem (Fermat's last theorem) in a dream, and scribbled the answer in the margin of a book. When he awoke, he found he could not read his scribblings. That theorem has yet to be proved definitively.
The chemist Kékulé was working on the structure of benzene. While relaxing in front of his fire, according to one version of the story, he watched the flames. Gradually, he imagined the flames making circles spinning in one direction, and then stopping, and spinning in reverse. He jumped up, realizing he had solved the benzene problem; the double bonds resonated, or were shared by the six carbon atoms.
You too may have insightful solutions like these. Observing children at play is another good place to observe insight. Some animals can learn by insight as well. During World War I, the German psychologist Wolfgang Köhler was interned on the island of Tenerife off the coast of Africa. There he worked with a chimp called Sultan. Sultan solved problems insightfully. The most famous was the box and banana problem. Köhler suspended a banana from the ceiling of Sultan's enclosure. Sultan could not reach the banana. After trying for awhile, he gave up. Later, he hopped up, moved a box under the banana, and retrieved it. That solution came to him insightfully. But, remember, Sultan had much previous experience with boxes. That was his preparation for an insightful solution.
