Abstract
The research examined some aspects of an hypothetical involvement of the eyes in the process of imagery and the individual differences in the modulation of the imagery-perception interaction of 59 (7 male and 52 female) undergraduate students in psychology. The subjects were asked to image with open eyes and to project, looking through a zoom lens, the “mental” image onto a white screen. While the subject was imaging, the experimenter moved the lever of the zoom lens in the direction of an hypothetical enlargement. This movement evoked different classes of responses: 46% of the subjects had a loss, even if for a short time, of the image, 37% of the subjects observed a strange and unexpected enlargement of the mental image, 7% did not observe any change in imagery, and 10% had other responses. A psychophysiological discussion concerned the strange phenomena observed in this research that have not yet been explored enough.
