The researchers found that to describe animals, the visually impaired rely on biological classifications, similar to the way scientists do it. According to Curiosity, a new study shows that visually impaired people have insight into animals, though they have never seen what hippos or sharks look like. “The first hand experience is not the only way to develop a rich understanding of the world around us,” said Judy Kim, a graduate student at Johns Hopkins University. Visually impaired people have very good knowledge of things like light and color, though it is unclear how they perceive the shape and learn about it. Some studies suggest that they may know through communication, like hearing someone say “flamingos are pink”. “People often think we can’t know what we don’t see. There are actually many ways to understand the world around,” Kim said. The team invited 20 visually impaired people and 20 normal people, arranged the names of animals according to size (smallest to largest) and height (lowest to highest). They then classify animals into groups based on shape, external characteristics and colors, eliminating species of different shapes or other characteristics (such as hippos with feathers or fur, skin or scales or not). In general, blind and normal people arrange in similar ways about the characteristics of each species. For example, both groups agreed that dolphins are similar in shape to sharks, and that sloths look like bears. 15/20 blind people and 19/20 normal people surveyed said elephants are bigger than rhinos. But there are still some differences between the two groups. Contrary to the idea that visually impaired people are aware of animals through the description of ordinary people, they have disagreements about characteristics that people most often see are colors. Ordinary people sort quite well animals by color. But when compared, it is difficult for them to divide them into shapes. While the visually impairment, it is easy to classify them according to the shape but not in the same color. The researchers found that to describe animals, the visually impairment relies on biologically similar categories of science. This is useful when distinguishing shapes and characteristics, for example birds with feathers and typical wing shapes. But it is ineffective in color because many different species of animals are the same color (swans, polar bears and sheep are white). Consequently, it is possible to conclude: The visually impairment has a wealth of information based on reasoning. “Sometimes people think that visual experience is the best way to learn about the world. But this study shows that language communication can still give us rich and accurate knowledge, even knowledge that at first glance looks intuitive, “said Marina Bedny, co-author of the study, and Assistant Professor of Psychological and Brain Science. “Both ordinary people and blind people live in civilized cities, and they don’t need to know about the wild world. But the animal world is obviously very attractive to people, “Bedny said.
