Subsequent research conducted by Haber and colleagues revealed that this eidetic ability is not particularly rare. While performing these experiments, Haber was amazed to hear of scores of children who could keep seeing any image in front of them - not just doctored ones like those used in ‘ghost’ images - even after the image was removed. ![]() You should see a color-inverted version of the picture very briefly. To experience the afterimage effect, stare intensely in the center of this specially processed image for 30-60 seconds, then move your gaze to a white surface such as a piece of paper or a nearby wall. This is a harmless mind trick that results from photoreceptors in your retina getting fatigued from focusing on the same color for too long. His interest in the subject was piqued during experiments on afterimages or “ghost” images, a phenomenon in which people, particularly children, can still see certain images in front of them for a brief period of time even after the photo is removed. One of the first prominent scientists who investigated eidetic memory is psychologist Ralph Norman Haber. For most people, these images are only stored for a few short seconds before being discarded or transferred to short-term memory. Eidetic memory is believed to be controlled primarily by the posterior parietal cortex in the brain, where visual stimuli are processed and fragments of images retained. ![]()
