CONTROL OF THE SUBJECTIVE PERSPECTIVE ON AN AMBIGUOUS FIGURE THROUGH OCULAR SCANNING

The purpose of this experiment was to study the contribution of oculom otor process to visual image construction, visual image generation and visual recognition of a figure. A reversible figure such as a Necker cube teas presented to subjects. In the first part of the experiment, scanning of the figures's outlines was varied along opposite direction s. In the second part, both perspective possibilities of the ambiguous figure were simultaneously presented and subjects had to recognize th e one they scanned. According to the choice they expressed, the perspe ctive subjects recognition depended on, the way they scanned the ambig uous figure. When recognizing, subjects serially imaged parts of the s hape. These data are suggestive of a shape recognition process through assimilation to an oculomotor program, whose execution is controlled by visual perceptual trace.
