There are still those, a quarter of a century after Köhler’s death, who believe that the ultimate explanation of all psychological phenomena will be written in the language of physiology. His attempt was not absurd. Remember, too, that when Köhler ﬁrst described his model, knowledge of the workings of the brain was sketchy, to say the least. It has been said that early neurophysiological attempts to probe the brain were like trying to understand people in the street from the top of a skyscraper, armed only with a giant needle.
Figures tend to be complete, coherent and in front of ground, which is seen as less distinct, is attended to less readily, and is often seen as ﬂoating behind the ﬁgure. When ﬁgure and ground share a contour (as they commonly do), then the contour is usually seen as belonging to the ﬁgure. 3 the immediate organization leads us to see a black triangle (the ﬁgure) in front of a white ground. But the printed page permits trickery. The white disc on the triangle, is it a ﬁgure? – in which case it will be seen as over the black (which is now ground) or is it an aperture?
An introspectionist approach to the explanation of Gestalt phenomena would have been essentially psychological or mental in ﬂavour. However, as we have seen, the hostility of the Gestalt movement to introspection rules out any explanation of this type. Physical Gestalten and the minimum principle Köhler considered the possibility that perceptual Gestalten were manifestations of a wider set of phenomena that included physical Gestalten. The reader will remember from an earlier section that studies of physical phenomena over the centuries had accumulated a mass of evidence to support a general principle of least effort or least energy – the minimum principle.
