"A complete theory would have to answer, among others, the following questions, given two adjoining retinal areas of different stimulation, under what conditions will the corresponding parts of the behavioural (perceptual) field appear of different whiteness but equal brightness (or "illumination"), when of different brightness but equal whiteness? A complete answer to this question would probably supply the key to the complete theory of colour perception in the broadest sense."
Kurt Koffka was a German psychologist and professor. He was born and educated in Berlin, Germany; he died in Northampton, Massachusetts, from coronary thrombosis. He was influenced by his maternal uncle, a biologist, to pursue science. He had many interests including visual perception, brain damage, sound localization, developmental psychology, and experimental psychology. He worked alongside Max
"To apply the category of cause and effect means to find out which parts of nature stand in this relation. Similarly, to apply the gestalt category means to find out which parts of nature belong as parts to functional wholes, to discover their position in these wholes, their degree of relative independence, and the articulation of larger wholes into sub-wholes."
Kurt Koffka"The general aim of my book has been but to point out a way in which a solution of these numerous problems (behavior and development) can be attained. The nature of mental development as it has been revealed to us is not the bringing together of separate elements, but the arousal and perfection of more and more complicated configurations in which both the phenomena of consciousness and the functions of the organism go hand in hand."
Kurt Koffka"Things look as they do because of the field organization to which the proximal stimulus distribution gives rise. This answer is final and can be so only because it contains the whole problem of organization itself."
Kurt Koffka"Why We See Things and Not the Holes Between Them. We can now attempt an answer to the question why we do so. Two of the factors of organization which we have so far discussed seem to me to be the most important causes of this effect. In the first place, the segregation and unification which occurs will separate areas of different degrees of internal articulation, and according to our law, the more highly articulated ones will become figures, the rest fusing together to form the ground. Look at any landscape photograph. You see the shape of the things, the mountains, and trees and buildings, but not of the sky."
Kurt Koffka"In his major work, Principles of Gestalt Psychology, Koffka (1935) devoted over 60 pages to the hypothesized role of ego in memory... Koffka distinguished between self and ego, the former being defined as a central subsystem of ego, but his analysis of memory was given in terms of the broader system, ego."
Kurt Koffka"In our theory the total field of excitation is divided into two major sub-systems, each containing numerous sub-systems of its own: the Ego and the environment. And the trace field which is created by the excitation field contains the same dichotomous organization."
