With reading difficulties can come other cognitive strengths
"The trick that makes Escher’s drawings intriguing is a geometric construction psychologists refer to as an “impossible figure,” a line-form suggesting a three-dimensional object that could never exist in our experience. Psychologists, including a team led by Catya von Károlyi of the University of Wisconsin-Eau Claire, have used such figures to study human cognition. When the team asked people to pick out impossible figures from similarly drawn illustrations that did not violate causality, they were surprised to discover that some people were faster at this than others. And most surprising of all, among those who were the fastest were those with dyslexia.
"Dyslexia is often called a “learning disability.” And it can indeed present learning challenges. Although its effects vary widely, children with dyslexia read so slowly that it would typically take them a half a year to read the same number of words other children might read in a day. Therefore, the fact that people who read so slowly were so adept at picking out the impossible figures was a big surprise to the researchers. After all, why would people who are slow in reading be fast at responding to visual representations of causal reasoning?"
