Theories On Drawing and Brain Function
Edwards's method of drawing and teaching was revolutionary when she published it in 1979. It received an immediate positive response, and is now widely accepted by artists, teachers, and others around the world. Underlying the method is the notion that the brain has two ways of perceiving and processing reality — one verbal and analytic, the other visual and perceptual. Edwards' method advocates suppressing the former in favor of the latter. It focuses on disregarding preconceived notions of what the drawn object should look like, and on individually "seeing" edges or lines, spaces, relationships, and lights and shadows, later combining them and seeing them as a whole, or gestalt.
Edwards's early work was based in part on her understanding of neuroscience, especially the cerebral hemisphere research which suggested that the two hemispheres of the brain have different functions. She spoke of verbal/analytic processing as taking place in the brain's left hemisphere, and visual/perceptual processing as taking place in the right. When later research showed that the locus of these activities is much less clear cut, she began calling the two modes "left mode" and "right mode", respectively.

Famous quotes containing the words theories, drawing, brain and/or function:
“The two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx’s concept was more comprehensive and less time-bound than Freud’s.”
—Erich Fromm (1900–1980)
“He who is in love is wise and is becoming wiser, sees newly every time he looks at the object beloved, drawing from it with his eyes and his mind those virtues which it possesses.”
—Ralph Waldo Emerson (1803–1882)
“The within, all that inner space one never sees, the brain and the heart and other caverns where thought and feeling dance their sabbath.”
—Samuel Beckett (1906–1989)
“Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
—Frank Smith (b. 1928)
