Adults born blind have rich insight into what animals they've never seen like hippos and sharks look like, a new study finds.
"First-person experience isn't the only way to develop a rich understanding of the world around us," says corresponding author Judy Kim, a doctoral candidate at Johns Hopkins University. "Essentially, the question is, how do we know what we know?"
While some previous research has shown that blind people do have knowledge of things like light and color, researchers still have little understanding of what blind people know about appearance and how they learn such information. Some studies suggest that people born blind remember verbal facts, like "flamingos are pink," so the research team wanted to investigate further.
"People often have the intuition that we can't know what we can't see," says Kim.
