Learning to read can be hard. For children with dyslexia, it can be especially hard. In a 2017 interview with American Public Media reporter Emily Hanford, neuroscientist Guinevere Eden argued that “reading is not a natural skill,” as our brains were designed to recognize objects—such as an animal loping toward us across the plains—but not necessarily letters. Eden pointed out that to become fluent readers, students must learn to bypass aspects of their brain’s “visual system” in order to understand, for example, that “b” and “d” are not just similar objects but different letters.
