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