Resumen de Evocation de l'image mentale d'un polygone par programmation de l'exploration visuelle de ses contours
The purpose of these experiments was to study the contribution of oculomotor processes to visual image construction and generation. In a first experiment, subjects scanned a square shape, then drew it with closed eyes. The results showed that both ocular and manual responses started from the same angle and moved into the same direction. When drawing, subjects mentally pictured a complete square. In a second experiment, an irregular shape replaced the square. The results showed that repeated scanning of the outlines allowed an incidental learning of the shape and that subjects memorized their ocular movements rather than the figure. When drawing, subjects serially imaged parts of the shape. To interpret the data, hypotheses concerning common processes underlying both motor intention of ocular movements and visual image generation are suggested.
