“In areas of the brain that represent the retinal image, more resources will be directed to processing large images than to processing small images because the processing is determined by the area of the retina that the image stimulates,” says Dr. They also found that most images were better remembered when they were presented as bigger relative to when they were presented as smaller. To their surprise, they found that even in this case, the participants remembered the large, blurry images better than the small, clear images. To understand whether this result was determined by size rather than amount of detail, the researchers also examined whether large, blurred images are better etched in memory than clear, small images, where the large images contained the same details as the small images. This phenomenon was not dependent on specific stimuli, the order in which the images appeared, their resolution, or the amount of information they contained. Time and time again the researchers found that the large images were better remembered (1.5 times more) than the small images. One hundred eighty-two subjects participated in seven different experiments. Each participant was shown different pictures in different sizes, each presented to them just once. Gilaie-Dotan’s lab, examined what happens to visual memory when participants were asked to look at pictures without knowing anything about a memory task to come. Shaimaa Masarwa and Olga Kreichman, PhD students in Dr. These findings can have many implications, including on the use of different types of electronic screens and the quality of information processing when we rely on large vs. The results of the study, just published in the journal Proceedings of the National Academy of Sciences, show for the first time that in natural vision, visual memory of images is affected by the size of the image on the retina. Her assumption was based on the fact that large images require the visual system to utilize greater resources for processing them. Sharon Gilaie-Dotan, of Bar-Ilan University’s School of Optometry and Vision Science and Gonda (Goldschmied) Multidisciplinary Brain Research Center, sought to determine whether large images are better remembered than small ones during natural daily behavior. The elements influencing whether we remember one image and not the other aren’t yet known, but researchers have assumed that image size and memory aren’t connected to one another, since we usually understand what appears in an image, whether it is large or small.Ī new study led by Dr. Some become etched in our memory and some don’t. Summary: In natural vision, visual memories of an image are affected by the size of the vision on the retina.Įvery day we encounter images on the wall, in newspapers, books, and electronic devices.
