dc.description.abstractThis thesis is based on the Gestalt hypothesis that the principles. of perceptual organization determine the perceptual groupings the person imposes on the stimulus field, and that these perceptual groupings are also actively grouped in the memory according to the same Gestalt principles of organization. This organization of perception and memory determine the characteristics of recall and reproduction. A brief review of previous work in this area is discussed with reference to changes in memory as a func­tion of time and as a function of competing traces. The methodology of these studies is criticized for three basic reasons: They begin with an organized stimulus, they use repeated reproductions from the same subjects, and they fail to objectively quantify their results. The experiment described in this thesis attempted to avoid the problems of the previous methods by using an isotropic (unorganized) stimulus, by employing a method of cascaded subjects, and by objectively quanti­fying the amount of organization in a subject's repro­duction of a stimulus by a psychophysical scaling technique. It was found that subjects organize the stimulus in order to remember it and that this organizational process in perception and memory determines the, characteristics of the reproductions. Thus the subjects' reproductions were more organized than the stimulus they viewed.en_US
