Excerpt from The Effect of Context Upon Perceptual DifferentiationThe role Of context has been further emphasized in a study by Gatti (17) on illusions in the perception of geometrical figures seen at rest and in motion. When such space relations appear in the parts Of a complex, they become changed or deformed, and this phenomenon has been termed by Catti the deforming nature of the complex.Numerous investigations have dealt with the effect of various factors on illusions Of reversible perspective. Donahue and Grif fiths for example, studied the in¿uence Of complexity on the ¿uctuations of such figures, using 8 well-known figures of the reversible perspective type, such as the staircase, cube, glass, book, tetrahedron, and various composite cube figures. They found that the greater the complexity of the figure, the slower the rate Of change, but that this factor Of complexity is not the most important. The most important factor was found to be the familiarity of the subject with the figure and with the two possible interpretations. The more familiar the figure, the more rapid was the rate of ¿uctuation, unless there was an unequal familiarity with the two interpretations Of the figure.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
