Sultan, one of the brightest of the early chimpanzees used for psychological research, was tested by Gestalt psychologist Wolfgang Köhler. Sultan is particularly recognized for his insight in solving numerous problems, including stacking or manipulating boxes to reach a reward and use of two sticks as a unit to rake food to a reachable distance.
Köhler conducted experiments similar to those of Hobhouse. [ 3 ] [ 4 ] Köhler with a background in many disciplines ( philosophy , history , natural science , and experimental psychology ) finished his doctorate under the supervision of Carl Stumpf at the Berlin Psychological Institute. [ 4 ]

In support of this argument, Costello summarizes an ape experiment that was conducted in the 1920s by Wolfgang Kohler. The principal player in the experiment was an ape named Sultan who was variously deprived of his bananas until he reasoned his way into obtaining them.

His device used short-focus lenses. Stratton used a one-tube, monocular device because this also reverses left and right and he wished to set up an experiment without distortion of depth perception. [5] In 1931 Theodor Erismann and Ivo Kohler conducted a series of experiments using mirror-prismatic upside down goggles employing only one mirror. [6]
