Abstract

In the preceding selection (see record 2007-10344-006) it was shown that a simultaneous perception of two colours in the same visual direction is possible when both objects are seen as independent figural wholes. The necessary separability of these objects cannot be achieved when they coincide perfectly, however; it is imperative that some part of one object shall extend beyond the corresponding boundary of the other. But this protruding part not only serves to bring about a separation between the two objects; it also acts to influence the colour of the overlapping (i.e, the "critical") area. Suppose, for example, that one sees a cross made of a transparent blue strip upon a yellow strip. If, looking through the aperture of a hole-screen, only the intersection is visible, this area will be seen to have a whitish grey colour. But this changes immediately when one lays aside the screen and sees the entire blue, or yellow strip, or both together. The critical area now assimilates the colour of the figure to which it is seen as belonging. It is to a systematic investigation of this phenomenon that we now turn. We shall be interested primarily in answering the following questions: Is there any uniformity in the influence exerted upon the critical area by the overlapping one (or vice versa)? Do these phenomena also make their appearance in the case of contrasting colours and of after-images? (The complete version of this article appeared as "Experimentelle Untersuchungen über die Aenderung von Farben unter dem Einfluss von Gestalten" ["Angleichungserscheinungen"], Zeitschr. f. Psychol., 1923, 92, 249-325.) (PsycInfo Database Record (c) 2023 APA, all rights reserved)
